Testosterone level: Can you boost it naturally? – Mayo Clinic

Aside from making healthy lifestyle choices and addressing medication side effects or untreated medical conditions, there's little you can do to naturally boost your testosterone level.

Testosterone levels vary greatly among men. In general, however, older men tend to have lower testosterone levels than do younger men. Testosterone levels gradually decline throughout adulthood about 1 percent a year after age 30 on average.

A blood test is the only way to diagnose a low testosterone level or a reduction in the bioavailability of testosterone. Some men have a lower than normal testosterone level without signs or symptoms. For most men, no treatment is needed. But for some others, very low testosterone levels lead to a condition in which bones become weak and brittle (osteoporosis). For others, low testosterone might cause changes in sexual function, sleep patterns, emotions and the body.

However, some of these signs and symptoms can be caused by factors other than low testosterone, including medication side effects, thyroid problems, depression and excessive alcohol use. There are also conditions, such as obstructive sleep apnea, that might affect testosterone levels. Once these conditions are identified and treated, testosterone typically will return to a normal level.

If you are experiencing signs and symptoms that might be the result of a low testosterone level, consult your doctor. He or she can evaluate possible causes for the way you feel and explain possible treatment options. In addition, these steps might help:

What are androgens?

Hormones are chemical messengers madeby glands in the body that are carried inthe blood to act on other organs in thebody. Hormones are needed for growth,reproduction and well-being.

Androgens are male sex hormones thatincrease at puberty and are needed for aboy to develop into a sexually mature adultwho can reproduce. The most importantandrogen is testosterone.

Testosterone is the most important androgen (male sex hormone) in men and it is needed for normal reproductive and sexual function. Testosterone is important for the physical changes that happen during male puberty, such as development of the penis and testes, and for the features typical of adult men such as facial and body hair and a masculine physique. Testosterone also acts on cells in the testes to make sperm.

Testosterone is also important for overall good health. It helps the growth of bones and muscles, and affects mood and libido (sex drive). Some testosterone is changed into oestrogen, the female sex hormone, and this is important for bone health in men.

Testosterone is mainly made in the testes. A small amount of testosterone is also made by the adrenal glands, which are walnut-sized glands that sit on top of the kidneys.

The pituitary gland and the hypothalamus,located at the base of the brain, controlthe production of male hormones andsperm. Luteinizing hormone (LH) andfollicle stimulating hormone (FSH) arethe two important messenger hormonesmade by the pituitary gland that act onthe testes.

LH is needed for the Leydig cells in thetestes to make testosterone, the male sexhormone. Testosterone and FSH from thepituitary gland then act together on theseminiferous tubules (sperm-producingtubes) in the testes to make sperm.

Androgen, or testosterone, deficiency iswhen the body is not able to make enoughtestosterone for the body to functionnormally. Although not a life-threateningproblem, androgen deficiency can affectyour quality of life.

Androgen deficiency due to diseases of the testes or hypothalamus-pituitary affects about one in 200 men under 60 years of age. It is likely that androgen deficiency is under-diagnosed and that many men are missing out on the benefits of treatment. About one in 10 older men may have testosterone levels lower than those in young men, but this is usually linked with chronic illness and obesity. The benefits and risks of testosterone treatment for such men are not yet known.

Testosterone levels in men are highestbetween the ages of 20 and 30 years. Asmen age there is a small, gradual drop intestosterone levels; they may drop by up toone third between 30 and 80 years of age.

Some men will have a greater drop intestosterone levels as they age, especiallywhen they are obese or have other chronic(long-term) medical problems. On the otherhand, healthy older men with normal bodyweight may not experience any drop inserum testosterone levels.

There is no such thing as male menopauseor andropause that can be compared tomenopause in women.

Low energy levels, mood swings, irritability,poor concentration, reduced muscle strengthand low sex drive can be symptoms ofandrogen deficiency (low testosterone).Symptoms often overlap with those of otherillnesses. The symptoms of androgen deficiencyare different for men of different ages.

Androgen deficiency can be caused bygenetic disorders, medical problems, ordamage to the testes or pituitary gland.Androgen deficiency happens when thereare problems within the testes or withhormone production in the brain. A commonchromosomal disorder that causes androgendeficiency is Klinefelters syndrome.

A diagnosis of androgen deficiency involveshaving a thorough medical evaluation andat least two blood samples (taken in themorning on different days) to measurehormone levels. Diagnosis should not be simply based on symptoms as these could becaused by other health problems that needdifferent treatment. A diagnosis of androgendeficiency is only confirmed when blood testsshow a lower than normal testosterone level.

A reference range is used as a guide by testing laboratories and doctors to decide whether a persons hormone levels are normal or low, and whether treatment may be needed. Testosterone is measured in units called nanomalor. The normal testosterone reference range for healthy, young adult men is about 8 to 27 nanomolar but these numbers vary between measurement systems.

Androgen deficiency is treated with testosterone therapy; this means giving testosterone in doses that return the testosterone levels in the blood to normal. Testosterone is prescribed for men with androgen deficiency confirmed by blood tests. Once started, testosterone therapy is usually continued for life and the man needs to be checked regularly by a doctor.

In Australia testosterone therapy is available in the form of injections, gels, creams, patches and tablets, and works very well for men with confirmed androgen (testosterone) deficiency. The type of treatment prescribed can depend on patient convenience, familiarity and cost. Commercial testosterone products contain only the natural testosterone molecule that is chemically produced from plant materials.

Side-effects are not expected because testosterone therapy aims to bring a mans testosterone levels back to normal. However, testosterone therapy can increase the growth of the prostate gland which can make the symptoms of benign prostate enlargement (such as needing to urinate more often) worse. In the case of prostate cancer, testosterone therapy is not used because of concerns that it can make the tumour grow. Too high a dose of testosterone can lead to acne, weight gain, gynaecomastia (breast development), male-pattern hair loss and changes in mood. Any side-effects should be managed by a doctor and the testosterone dose lowered.

There are many herbal products marketed, particularly on the Internet, as treatmentsthat can act like testosterone and improve muscle strength and libido (sex drive). However, there are no known herbal products that can replace testosterone in the body and be used to treat androgen deficiency.

Testosterone therapy generally stops the production of the pituitary hormones FSH and LH, which reduces the size of the testes and can lower or stop sperm being made.

Testosterone treatment should not be given to a man wanting to become a father in the foreseeable future. If sperm production was normal before testosterone therapy, it usually recovers after treatment stops but it can take many months to go back to normal.

Testosterone therapy in men with androgen deficiency aims to bring testosterone levels back to normal and to return muscle strength and energy levels back to normal. However, the use of androgens (anabolic steroids) by normal men to improve athletic performance is illegal and has important short-term and long-term health risks.

Men who use anabolic steroids will lower or even turn off their own testosterone and sperm production. It may take many months for testosterone levels and sperm counts to return to normal after stopping anabolic steroids.

There are no known ways to prevent androgen deficiency caused by damage to the testes or pituitary gland. However, if you live a healthier lifestyle and manage other health problems your testosterone levels may improve, if your low testosterone levels are caused by other illness.

Not all men have a drop in testosterone levels with age. A healthy lifestyle may help you to keep testosterone levels normal.

Oxandrolone, sold under the brand names Oxandrin and Anavar, among others, is an androgen and anabolic steroid (AAS) medication which is used to help promote weight gain in various situations, to help offset protein catabolism caused by long-term corticosteroid therapy, to support recovery from severe burns, to treat bone pain associated with osteoporosis, to aid in the development of girls with Turner syndrome, and for other indications.[4][5][6] It is taken by mouth.[4]

Side effects of oxandrolone include symptoms of masculinization such as acne, increased hair growth, voice changes, and increased sexual desire.[4] Uniquely among most AAS that are active by mouth, it seems to have little risk of liver damage.[4][7] The drug is a synthetic androgen and anabolic steroid, hence is an agonist of the androgen receptor (AR), the biological target of androgens such as testosterone and dihydrotestosterone.[4][8] It has strong anabolic effects and weak androgenic effects, which give it a mild side effect profile and make it especially suitable for use in women.[4]

Oxandrolone was first described in 1962 and was introduced for medical use in 1964.[4] It is used mostly in the United States.[4][9] In addition to its medical use, oxandrolone is used to improve physique and performance.[4][10] The drug is a controlled substance in many countries, so nonmedical use is generally illicit.[4][11][12][13]

Oxandrolone has been researched and prescribed as a treatment for a wide variety of conditions. It is FDA-approved for treating bone pain associated with osteoporosis, aiding weight gain following surgery or physical trauma, during chronic infection, or in the context of unexplained weight loss, and counteracting the catabolic effect of long-term corticosteroid therapy.[14][15] As of 2016[update], it is often prescribed off-label to quicken recovery from severe burns, aid the development of girls with Turner syndrome, and counteract HIV/AIDS-induced wasting. Oxandrolone improves both short-term and long-term outcomes in people recovering from severe burns and is well-established as a safe treatment for this indication.[5][6] It is also used in the treatment of idiopathic short stature, anemia, hereditary angioedema, alcoholic hepatitis, and hypogonadism.[16][17]

Medical research has established the effectiveness of oxandrolone in aiding the development of girls with Turner syndrome. Although oxandrolone has long been used to accelerate growth in children with idiopathic short stature, it is unlikely to increase adult height, and in some cases may even decrease it. Oxandrolone has, therefore, largely been replaced by growth hormone for this use.[18] Children with idiopathic short stature or Turner syndrome are given doses of oxandrolone far smaller than those given to people with burns to minimize the likelihood of virilization and premature maturation.[18][19]

Many bodybuilders and athletes use oxandrolone for its muscle-building effects.[4] It is much more anabolic than androgenic, so women and those seeking less intense steroid regimens use it particularly often.[4] Many also value oxandrolone's low hepatotoxicity relative to most other orally active AASs.[4]

Like other AASs, oxandrolone may worsen hypercalcemia by increasing osteolytic bone resorption.[14] When taken by pregnant women, oxandrolone may have unintended effects such as masculinization on the fetus.[14]

Women who are administered oxandrolone may experience virilization, irreversible development of masculine features such as voice deepening, hirsutism, menstruation abnormalities, male-pattern hair loss, and clitoral enlargement.[18][14][19] Oxandrolone may disrupt growth in children, reducing their adult height.[20][bettersourceneeded] Because of these side effects, doses given to women and children are minimized and people are usually monitored for virilization and growth abnormalities.[18][19] Like other androgens, oxandrolone can cause or worsen acne and priapism (unwanted or prolonged erections).[14][20] Oxandrolone can also reduce males' fertility, another side effect common among androgens.[20] In an attempt to compensate for the exogenous increase in androgens, the body may reduce testosterone production via testicular atrophy and inhibition of gonadotropic activity.[14]

Unlike some AASs, oxandrolone does not generally cause gynecomastia because it is not aromatized into estrogenic metabolites.[21] However, although no reports of gynecomastia were made in spite of widespread use, oxandrolone was reported in a publication in 1991 to have been associated with 33cases of gynecomastia in adolescent boys treated with it for short stature.[22][23] The gynecomastia developed during oxandrolone therapy in 19 of the boys and after the therapy was completed in 14 of the boys, and 10 of the boys had transient gynecomastia, while 23 had persistent gynecomastia that necessitated mastectomy.[22][23] Though transient gynecomastia is a natural and common occurrence in pubertal boys, the gynecomastia associated with oxandrolone was of a late/delayed onset and was persistent in a high percentage of the cases.[22][23] As such, the researchers stated, "although oxandrolone cannot be implicated as stimulatory [in] gynecomastia", a possible relationship should be considered in clinicians using oxandrolone in adolescents for growth stimulation.[22][23]

Uniquely among 17-alkylated AAS, oxandrolone shows little to no hepatotoxicity, even at high doses.[7][unreliable medical source?][24] No cases of severe hepatotoxicity have been singularly attributed to oxandrolone.[24] However, elevated liver enzymes have been observed in some people, particularly with high doses and/or prolonged treatment, although they return to normal ranges following discontinuation.[24] In any case, oxandrolone may be among the safest 17-alkylated AASs in terms of hepatotoxicity.[7][unreliable medical source?]

Oxandrolone greatly increases warfarin's blood-thinning effect, sometimes dangerously so.[25] In April 2004, Savient Pharmaceuticals published a safety alert through the FDA warning healthcare professionals of this.[26] Oxandrolone can also inhibit the metabolism of oral hypoglycemic agents.[14] It may worsen edema when taken alongside corticosteroids or adrenocorticotropic hormone.[14]

Like other AASs, oxandrolone is an agonist of the androgen receptor, similar to androgens such as testosterone and DHT.[4] This increases protein synthesis, which increases muscle growth, lean body mass, and bone mineral density.[6]

Compared to testosterone and many other AASs, oxandrolone is less androgenic relative to its strength as an anabolic.[4][27] Oxandrolone has about 322 to 633% of the anabolic potency and 24% of the androgenic potency of methyltestosterone.[4] Similarly, oxandrolone has as much as 6times the anabolic potency of testosterone and has significantly reduced androgenic potency in comparison.[4] The reduced ratio of anabolic to androgenic activity of oxandrolone often motivates its medical use in children and women because less androgenic effect implies less risk of virilization.[4] The bodybuilding community also considers this fact when choosing between AASs.[4]

As oxandrolone is already 5-reduced, it is not a substrate for 5-reductase, hence is not potentiated in androgenic tissues such as the skin, hair follicles, and prostate gland.[4] This is involved in its reduced ratio of anabolic to androgenic activity.[4] Due to the substitution of one of the carbon atoms with an oxygen atom at the C2 position in the A ring, oxandrolone is resistant to inactivation by 3-hydroxysteroid dehydrogenase in skeletal muscle.[4] This is in contrast to DHT, and is thought to underlie the preserved anabolic potency with oxandrolone.[4] Because it is 5-reduced, oxandrolone is not a substrate for aromatase, hence cannot be aromatized into metabolites with estrogenic activity.[4] Oxandrolone similarly possesses no progestogenic activity.[4]

Oxandrolone is, uniquely, far less hepatotoxic than other 17-alkylated AASs, which may be due to differences in metabolism.[24][4][1][3]

The oral bioavailability of oxandrolone is 97%.[2] Its plasma protein binding is 94 to 97%.[2] The drug is metabolized primarily by the kidneys and to a lesser extent by the liver.[1][2] Oxandrolone is the only AAS that is not primarily or extensively metabolized by the liver, and this is thought to be related to its diminished hepatotoxicity relative to other AAS.[1][3] Its elimination half-life is reported as 9.4 to 10.4hours, but is extended to 13.3hours in the elderly.[2][3] About 28% of an oral dose of oxandrolone is eliminated unchanged in the urine and 3% is excreted in the feces.[3]

Oxandrolone is a synthetic androstane steroid and a 17-alkylated derivative of DHT.[28][29][4] It is also known as 2-oxa-17-methyl-5-dihydrotestosterone (2-oxa-17-methyl-DHT) or as 2-oxa-17-methyl-5-androstan-17-ol-3-one, and is DHT with a methyl group at the C17 position and the C2 carbon replaced with an oxygen atom.[28][29][4] Closely related AASs include the marketed AAS mestanolone (17-methyl-DHT), oxymetholone (2-hydroxymethylene-17-methyl-DHT), and stanozolol (a 2,3-pyrazole A ring-fused derivative of 17-methyl-DHT) and the never-marketed/designer AAS desoxymethyltestosterone (3-deketo-17-methyl-2-DHT), methasterone (2,17-dimethyl-DHT), methyl-1-testosterone (17-methyl-1-DHT), and methylstenbolone (2,17-dimethyl-1-DHT).[28][29][4]

Oxandrolone was first made by Raphael Pappo and Christopher J. Jung while at Searle Laboratories (now part of Pfizer). The researchers first described the drug in 1962.[4][30][31] They were immediately interested in oxandrolone's very weak androgenic effects relative to its anabolic effects.[30][4] It was introduced as a pharmaceutical drug in the United States in 1964.[4]

The drug was prescribed to promote muscle regrowth in disorders which cause involuntary weight loss, and is used as part of treatment for HIV/AIDS.[4] It had also been shown to be partially successful in treating cases of osteoporosis.[4] However, in part due to bad publicity from its illicit use by bodybuilders, production of Anavar was discontinued by Searle Laboratories in 1989.[4] It was picked up by Bio-Technology General Corporation, which changed its name to Savient Pharmaceuticals, which following successful clinical trials in 1995, released it under the brand name Oxandrin.[4] BTG subsequently won approvals for orphan drug status by the Food and Drug Administration for treating alcoholic hepatitis, Turner syndrome, and HIV-induced weight loss.[4] It is also indicated as an offset to protein catabolism caused by long-term administration of corticosteroids.[4]

Oxandrolone is the generic name of the drug and its INN, USAN, USP, BAN, DCF, DCIT, and JAN, while ossandrolone is or was formerly the DCIT.[28][29][32][9][33]

The original brand name of oxandrolone was Anavar, which was marketed in the United States and the Netherlands.[4][34] This product was eventually discontinued and replaced in the United States with a new product named Oxandrin, which is the sole remaining brand name for oxandrolone in the United States.[4][35] Oxandrolone has also been sold under the brand names Antitriol (Spain), Anatrophill (France), Lipidex (Brazil), Lonavar (Argentina, Australia, Italy), Protivar, and Vasorome (Japan), among others.[4][29][34][36] Additional brand names exist for products that are manufactured for the steroid black market.[4]

Among those using oxandrolone for nonmedical purposes, it is often referred to colloquially as "Var", a shortened form of the brand name Anavar.[37][38][39][self-published source]

Oxandrolone is one of the few AASs that remain available for medical use in the United States.[35] The others (as of November 2017) are testosterone, testosterone cypionate, testosterone enanthate, testosterone undecanoate, methyltestosterone, fluoxymesterone, nandrolone decanoate, and oxymetholone.[35]

Outside of the United States, the availability of oxandrolone is quite limited.[4][9] With the exception of Moldova, it is no longer available in Europe.[4] Oxandrolone is available in some less-regulated markets in Asia such as Malaysia.[4] It is also available in Mexico.[4] Historically, oxandrolone has been marketed in Argentina, Australia, Brazil, France, Italy, Japan, and Spain, but it appears to no longer be available in these countries.[4][29][34][9]

In the United States, oxandrolone is categorized as a Schedule III controlled substance under the Controlled Substances Act along with many other AASs.[11] It is a Schedule IV controlled substance in Canada,[12] and a Schedule 4 controlled drug in the United Kingdom.[13]

Oxandrolone is sometimes used as a doping agent in sports. Cases of doping with oxandrolone by professional athletes have been reported.

Testosterone Levels Test: MedlinePlus Lab Test Information

What is a testosterone levels test?

Testosterone is the main sex hormone in males. During a boy's puberty, testosterone causes the growth of body hair, muscle development, and deepening of the voice. In adult men, it controls sex drive, maintains muscle mass, and helps make sperm. Women also have testosterone in their bodies, but in much smaller amounts.

This test measures the levels of testosterone in your blood. Most of the testosterone in the blood is attached to proteins. Testosterone that is not attached to a protein is called free testosterone. There are two main types of testosterone tests:

Testosterone levels that are too low (low T) or too high (high T) can cause health problems in both men and women.

Other names: serum testosterone, total testosterone, free testosterone, bioavailable testosterone

A testosterone levels test may be used to diagnose several conditions, including:

You may need this test if you have symptoms of abnormal testosterone levels. For adult men, it's mostly ordered if there are symptoms of low T levels. For women, it's mostly ordered if there are symptoms of high T levels.

Symptoms of low T levels in men include:

Symptoms of high T levels in women include:

Boys may also need a testosterone levels test. In boys, delayed puberty can be a symptom of low T , while early puberty may be a symptom of high T.

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

You don't need any special preparations for a testosterone levels test.

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

Results mean different things depending on whether you are a man, woman, or boy.

For men:

For women:

For boys:

If your results are not normal, it doesn't necessarily mean you have a medical condition needing treatment. Certain medicines, as well as alcoholism, can affect your results. If you have questions about your results, talk to your health care provider.

Men who are diagnosed with low T levels may benefit from testosterone supplements, as prescribed by their health care provider. Testosterone supplements are not recommended for men with normal T levels. There is no proof they provide any benefits, and in fact they may be harmful to healthy men.

Testosterone | FDA Label – | AIDSinfo

Drug Description

Testosterone is a naturally occurring androgenic steroid hormone. [1]

[1] AHFS Drug Information 2007; p. 3071

Testosterone (transdermal and injection) is used to treat hypogonadism, a condition that commonly occurs in HIV infected men, particularly those whose disease has progressed to AIDS. In addition to typical manifestations of hypogonadism (e.g., impaired sexual mood and functioning, loss of body hair, gynecomastia, bone loss, impaired sense of well-being), HIV infected men with hypogonadism may exhibit a disproportionate loss of lean body mass and muscle wasting. Testosterone replacement therapy is considered the treatment of choice for androgen deficiency and AIDS wasting in this population. [1] It has been investigated to assess its efficacy in reducing symptoms of increased visceral fat in HIV infected men. [2] Transdermal testosterone has also been investigated to determine its safety and efficacy in treating weight loss in HIV infected women. [3] [4]

Testosterone is the principal endogenous androgen. Endogenous androgens are responsible for a number of physical conditions, including alterations in body musculature and fat distribution. [1] Loss of lean body mass is a common complication of HIV/AIDS, and HIV infected individuals undergoing highly active antiretroviral therapy (HAART) have a high incidence of lipodystrophy. Although the pathophysiologies of wasting and visceral obesity common to HIV infection are multifactorial, testosterone replacement appears to have a favorable impact on these syndromes. [2]

Testosterone produces retention of nitrogen, potassium, sodium, and phosphorus and increases protein anabolism. [3] Androgens are highly lipid-soluble and enter target cells by passive diffusion. Testosterone or the active metabolite 5-alpha-dihydrotestosterone (DHT) binds to an intracellular androgen receptor, which then translocates to the nucleus and attaches to specific hormone receptor elements on the chromosome. This process initiates or suppresses transcription and protein synthesis. Testosterone can produce estrogenic effects as a result of its conversion to estrogen. Endogenous plasma testosterone is maintained and regulated by gonadotropins within a normal range by a negative feedback system involving the hypothalamus and pituitary. Androgens also stimulate red blood cell production by enhancing production of erythropoietic stimulating factors. [4]

Esters of testosterone cypionate and testosterone enanthate given via intramuscular (IM) injection are absorbed slowly from the lipid tissue phase at the injection site, with peak serum concentrations reached about 72 hours after the dose is given. These esters' slow absorption results in a prolonged duration of action of 2 to 4 weeks after administration. By contrast, testosterone propionate given by IM injection has a comparatively short duration of action. Irritation at the IM injection site may cause erratic absorption of any testosterone ester. [5]

Transdermal testosterone is absorbed systemically through the skin. Approximately 10% of a testosterone gel dose is absorbed into systemic circulation. Increases in serum testosterone concentrations occur within 30 minutes of the application of a 100-mg dose of 1% gel. In most patients, physiologic concentrations are achieved within 4 hours, with percutaneous absorption maintained throughout the 24-hour dosing period. Serum testosterone concentrations reach steady state by the second or third day of dosing with the 1% gel. [6]

Percutaneous absorption of testosterone via transdermal systems varies considerably among individual patients; however, serum testosterone concentrations generally reach the normal physiologic range within the first day of dosing. These levels are maintained with no accumulation of testosterone during continuous dosing. Because genital skin contains high concentrations of 5-alpha-reductase, serum concentrations of the active metabolite DHT are generally in the supraphysiologic range for men following chronic scrotal application of testosterone transdermal systems. In some men, however, DHT concentrations may increase initially and then decrease to normal levels with continued therapy. [7]

In serum, testosterone is bound with high affinity to sex hormone binding globulin (SHBG) and with low affinity to albumin. The amount of SHBG in serum and the total testosterone concentration determine the distribution of pharmacologically active and nonactive forms of the androgen. [8] Approximately 40% of endogenous testosterone in plasma is bound to SHBG, 2% remains unbound, and the rest is bound to albumin and other proteins. [9]

Testosterone is in FDA Pregnancy Category X. Studies in humans have shown that androgens cause masculinization of the external genitalia of the female fetus. [10] Because the risks clearly outweigh the possible benefits in women who are pregnant or who can become pregnant, androgens are contraindicated in these patients. Women who become pregnant while receiving testosterone should be informed of the potential hazard to the fetus. [11] It is not known whether testosterone is distributed into breast milk; however, because of the potential for adverse effects in the nursing infant, androgens are not recommended for women who are breastfeeding. [12]

Protein binding of testosterone is very high (approximately 99%), with 80% binding to SHBG and 19% to albumin. The metabolite DHT has greater affinity for SHBG than does testosterone. [13]

Biotransformation of testosterone occurs primarily through the liver. [14] Both IM and transdermal administration of testosterone avoid first-pass metabolism. Testosterone esters for injection first undergo hydrolysis of the ester to the active form, free testosterone. Free testosterone is further converted into two of the major active metabolities, DHT and estradiol. The plasma half-life of testosterone is highly variable, ranging from 10 to 100 minutes. Both testosterone and its metabolites are renally excreted in urine and feces (approximately 90% and 6%, respectively, of an IM dose). [15]

The most frequent adverse effects of testosterone include abdominal or back pain; abnormal ejaculation, or frequent or continuing penile erections; acne or local blistering of skin; anxiety; bladder irritability or urinary tract infection; breast soreness; cholestatic hepatitis, jaundice, and abnormal liver function tests; diarrhea; dizziness; edema; excessive sexual stimulation; flushing of the skin; gynecomastia; habituation; headache; hirsutism; hypercalcemia; increased serum cholesterol; insomnia; libido changes; male pattern baldness; mental depression or irritability; nausea; oligospermia; pain or irritation at injection site; priapism; prostate disorders; redness, burning, or itching at transdermal application site; retention of water, sodium, chloride, potassium, and inorganic phosphates; and seborrhea. [1] [2] [3] [4]

Frequent adverse effects among women receiving testosterone therapy include indications of virilization (amenorrhea or other menstrual irregularities; clitoral enlargement; hirsutism; and hoarseness or deepening of the voice). [5]

Pregnant women should not receive testosterone therapy because of the potential for serious harm to the fetus. In addition, pregnant women should avoid skin contact with application sites on patients because of the possibility that transdermal testosterone can be transferred from patients to their sexual partners or others in close physical contact. Potential adverse effects to female offspring exposed to testosterone in utero include clitoral hypertrophy, labial fusion of the external genital fold, abnormal vaginal development, and persistence of a urogenital sinus.

Because concurrent administration of testosterone with oral coumarin- or indandione-derivative anticoagulants can cause bleeding in some patients, dosage adjustment of anticoagulants may be needed during and after coadministration of the two drugs. Concurrent administration of testosterone with hepatotoxic drugs, including but not limited to abacavir, lamivudine, nevirapine, tenofovir, and zidovudine, may increase the incidence of hepatotoxicity. Patients should be carefully monitored, especially those undergoing long-term therapy or those with a history of liver disease. [1]

Increased serum levels of oxyphenbutazone have been reported in patients receiving androgens and oxyphenbutazone concurrently. The use of testosterone by diabetic patients may result in decreased blood glucose levels and reduced insulin requirements. Increased clearance of propranolol has been reported in patients receiving the drug concurrently with testosterone cypionate. [2] [3] Concurrent administration of testosterone with corticotropin (ACTH) or corticosteroids may enhance edema formation; these drugs should be combined with caution, particularly in patients with cardiac or hepatic disease.

High and Low Testosterone Levels in Men

What is testosterone?

Testosterone is considered to be the "male hormone" that's produced in men by the testes. Although women's ovaries produce some testosterone, the hormone is produced in much higher concentrations in men and it is responsible for many of the secondary sex characteristics seen in men such as a deeper voice and hair on the chest, in addition to contributing to a healthy libido, building muscle mass, and maintaining energy levels.

The problems associated with high testosterone levels are infrequent and rare in middle-aged and elderly men who are not receiving testosterone or other steroid treatments. When the testosterone level becomes out of balance, it usually becomes too low rather than too elevated.

What are the signs and symptoms of low testosterone levels in men?

The most common "out of balance" testosterone levels are found to be on the low side of normal; this occurs because a male's highest testosterone level usually peaks at about age 20, and then it decreases slowly with age. It has been suggested that a 1% decrease in testosterone level per year is not unusual for middle-aged (30 to 50 years old) and older males. While this decrease may not be noticeable in some men, others may experience significant changes starting in their middle-aged years or more commonly at age 60 and above. This drop in testosterone levels is sometimes termed hypogonadism, "male menopause" or andropause.

Low testosterone levels may result in a decline in:

Additional symptoms of in low-T in men may include:

What are normal or average testosterone levels in men?

In general, the normal range in males is about 270 to 1070 ng/dL with an average level of 679 ng/dL. A normal male testosterone level peaks at about age 20, and then it slowly declines. Testosterone levels above or below the normal range are considered by many to be out of balance. Moreover, some researchers suggest that the healthiest men have testosterone levels between 400 - 600 ng/dL.

What are the benefits of higher than normal testosterone levels?

Examples of benefits, which are modest, of men having higher than average testosterone levels include:

What are the disadvantages of having higher than average testosterone levels?

Examples of drawbacks or disadvantages of men having higher than average testosterone levels include:

What are anabolic steroids, and what their side effects?

Both men and women that utilize anabolic steroids to gain an athletic "edge" (for example, some professional athletes) or to increase muscle mass (for example, some bodybuilders) may experience high levels of testosterone and develop complications, and side effects, for example:

What is the treatment for low-T in men?

There is treatment available low testosterone levels. Doctors may prescribe medications that contain testosterone such as:

What men should not use testosterone therapy?

Not all men may be candidates for this type of treatment.

How often should a man have his testosterone levels checked?

So, how does one ensure that testosterone levels remain in balance? Some doctors suggest that monitoring testosterone levels every five years, starting at age 35, is a reasonable strategy to follow. If the testosterone level falls too low or if the individual has the signs and symptoms of low testosterone levels described above, testosterone therapy can be considered. However, once testosterone therapy is initiated, testosterone levels should be closely monitored to make sure that the testosterone level does not become too high, as this may cause stress on the individual, and high testosterone levels may result in some of the negative problems (described previously) seen.

Finding the appropriate balance of testosterone is possible through discussions with your doctor, and it requires your willingness to have testosterone levels checked before the initiation of therapy and then checked routinely in the future.

The Reality behind Testosterone Therapy

If you're in midlife, chances are you've heard a lot about testosterone therapy for women. If you believe everything you read, supplementing with this hormone can improve your sex life, give you more energy, clear up your skin and help you run a four-minute mile. The reality, however, is far different. For example, testosterone therapy could cause acne, facial hair and a deeper voice.

While there is evidence that testosterone therapy can help some women with certain health-related issues, primarily sexual disorders, it most assuredly is not a wonder drug, and it is not recommended for most women.

First, a few words about testosterone. Testosterone is an androgen, or sex-related hormone. Although considered "male" hormones, androgens play important roles in a woman's reproductive cycle and overall health. Produced in your ovaries, adrenal glands and fat cells, androgens like testosterone have more than 200 actions in women.

Learn more about the signs of high testosterone in women.

One of those actions is to contribute to your sexual arousal. This is the physical part of sexthe "tingling" feeling that lets you know your body, at least, is ready for action. Desire, however, if the part of you that determines interest and makes you want to sneak up behind your partner and begin kissing the back of his or her neck.Because testosterone levels can fluctuate significantly and because women have relatively low levels of testosterone, testosterone tests will not necessarily indicate whether a woman's lack of desire or arousal is related to naturally occurring testosterone. However, studies do find that supplemental testosterone, delivered in the form of a patch, improves sexual desire and responsiveness and increases the frequency of sexual activity.

Unlike estrogen, androgen levels don't suddenly drop when you reach natural menopause. Instead, androgen production begins slowly falling in your twenties. By the time you reach menopause, you're producing about half as much as you made at puberty. However, your ovaries may still continue to produce small amounts of androgens even after menopause. Some studies show menopausal ovaries continue to produce testosterone; other studies show they do not. One thing is for sure: if your ovaries are removed or damaged, you will go into surgical or early menopause. Some women who experience surgical menopause report a drop in sexual desire and drive.

We're still not quite sure whether the reduced androgen levels that occur with aging are responsible for the loss of sexual drive some women experience as they age. What is clear, however, is that supplemental testosterone therapy improves some women's ability to become aroused and the intensity of their orgasms after menopause, particularly women thrust into sudden menopause.

If your health care professional thinks you might benefit from androgen therapyalso called testosterone therapyyou will likely be started on a very small dose and monitored carefully.

Keep in mind, however, that there is no FDA-approved form of testosterone for treating sexual disorders in women. Nonetheless, your health care professional can prescribe a testosterone product approved for other indications. Examples include compounded testosterone creams and testosterone patches, gels, creams or pills approved for use in men. They should only be given to women if doses are reduced considerably, and blood testosterone levels are closely monitored, which can be difficult to do.

There are few, if any, side effects from the small amounts of supplemental testosterone used to treat sexual desire disorders in women, although your health care professional should monitor you closely. You should also know that there is very little evidence about the effects of testosterone on women not taking supplemental estrogen, which is why your health care professional shouldn't prescribe androgen therapy without estrogen.

Bottom line: If your lack of sexual drive is affecting your relationship and/or your quality of life, talk to your health care professional about your options.

Treating low testosterone levels – Harvard Health

Testosterone is the hormone that gives men their manliness. Produced by the testicles, it is responsible for male characteristics like a deep voice, muscular build, and facial hair. Testosterone also fosters the production of red blood cells, boosts mood, keeps bones strong, and aids thinking ability.

Testosterone levels peak by early adulthood and drop as you ageabout 1% to 2% a year beginning in the 40s. As men reach their 50s and beyond, this may lead to signs and symptoms, such as impotence or changes in sexual desire, depression or anxiety, reduced muscle mass, less energy, weight gain, anemia, and hot flashes. While falling testosterone levels are a normal part of aging, certain conditions can hasten the decline. These include:

Millions of men use testosterone therapy to restore low levels and feel more alert, energetic, mentally sharp, and sexually functional. But it's not that simple. A man's general health also affects his testosterone levels. For instance, being overweight, having diabetes or thyroid problems, and taking certain medications, such as glucocorticoids and other steroids, can affect levels. Therefore, simply having low levels does not always call for taking extra testosterone.

Doctors diagnose low testosterone based on a physical exam, a review of symptoms, and the results of multiple blood tests since levels can fluctuate daily.

If your doctor diagnoses low testosterone, other tests may be considered before therapy. For example, low testosterone can speed bone loss, so your doctor may recommend a bone density test to see whether you also need treatment for osteoporosis.

Prostate cancer is another concern, as testosterone can fuel its growth. The Endocrine Society recommends against testosterone supplementation in men who have prostate cancer or have a prostate nodule that can be felt during a digital rectal exam.

In most cases, men need to have both low levels of testosterone in their blood and several symptoms of low testosterone to go on therapy.

It is possible to have low levels and not experience symptoms. But if you do not have any key symptoms, especially fatigue and sexual dysfunction, which are the most common, it is not recommended you go on the therapy given the uncertainty about long-term safety.

Even if your levels are low and you have symptoms, therapy is not always the first course of action. If your doctor can identify the source for declining levelsfor instance, weight gain or certain medicationhe or she may first address that problem.

If you and your doctor think testosterone therapy is right for you, there are a variety of delivery methods to consider, as found in the Harvard Special Health Report Men's Health: Fifty and Forward.

Most men feel improvement in symptoms within four to six weeks of taking testosterone therapy, although changes like increases in muscle mass may take from three to six months.
