Your Guide to What Testosterone Is and What It Does for Your Body

What Effect Does Testosterone Have on the Body

In female adults, high levels of testosterone may be a sign of polycystic ovary syndrome (PCOS). This condition is very common — up to 15% of females of reproductive age have it. There’s a wide range of normal or healthy levels of testosterone circulating in the bloodstream.

Some studies have found no greater risk of prostate cancer with testosterone replacement therapy, but it continues to be a topic of ongoing research. Normal male testosterone levels range between 280 and 1,100 nanograms per deciliter (ng/dL) for adult males, and between 15 and 70 ng/dL for adult females, according to the University of Rochester Medical Center. While testosterone production naturally tapers off as a man ages, other factors can cause hormone levels to drop. However, many men with normal testosterone levels have similar symptoms, so a direct connection between testosterone levels and symptoms is not always clear.

“Anabolic” refers to muscle building, and “androgenic” refers to increased male sex characteristics. Testosterone is the main androgen, meaning it stimulates the development of male characteristics. Your adrenal glands also produce the hormone dehydroepiandrosterone (DHEA), which your body transforms into testosterone and estrogen.

And since the development and transfer of adaptive traits relies on the entire developmental system, not just the genes, relevant changes in non-genetic features of the system can bring about significant shifts in gendered behaviour. Possible side effects include acne, hair growth on the face and body, male-pattern hair loss, and oily skin. Excessive doses of testosterone can result in irreversible side effects such as enlargement of the clitoris and lowering of the voice. When a patient of mine decides to stop taking testosterone, it is rarely because of side effects and almost always because it simply isn’t working for her. Unlike with estrogen, for which blood levels are rarely required, testosterone therapy requires being tested to make sure yours is in the right range.

The existence and direction of the behavioural differences may be due to ‘deep-seated, biological factors’, but culture heavily influences how those differences play out. That’s why the question of whether male promiscuity, risk-taking and competitiveness were sexually selected adaptations for reproductive success simply doesn’t have the implications for now and the future that we usually assume they do. Nor does wellbutrin increase testosterone (https://www.primopianomolise.it/art/integratore_testosterone_1.html) it necessarily mean that a hormonal endowment prefigures the male brain for these traits (although that’s not to deny the likelihood of sex-differentiated initial ‘tilts’). So, while a gendered culture influences how these traditional roles play out, I don’t see the evidence that it imposes them.

Headquartered in Pittsburgh, UPMC is a world-renowned health care provider and insurer. We operate 40 hospitals and 800 doctors’ offices and outpatient centers, with locations throughout Pennsylvania, Maryland, New York, West Virginia, and internationally. We employ 4,900 physicians, and we are leaders in clinical care, groundbreaking research, and treatment breakthroughs. News & World Report consistently ranks UPMC Presbyterian Shadyside as one of the nation’s best hospitals in many specialties. You should have regular checkups with your doctor while undergoing TRT. Ovary or adrenal gland tumors and polycystic ovarian syndrome are potential causes. Early puberty can be caused by tumors and a condition known as congenital adrenal hyperplasia.

While males with Klinefelter syndrome can’t have children naturally, they may be able to have biological children with assisted reproductive technology. Your doctor may also want to measure your iron levels to check for haemochromatosis. They may refer you for a genetic test called a karyotype to check for genetic conditions such as Klinefelter’s syndrome. We should always be cautious not to treat sex-correlated patterns as a ‘general rule’, including the related assumption that sex always gets its ‘work’ done in the same way across species. The evidence suggests that sex is indeed an important concept for explaining the evolution of mating systems. But it’s part of a remarkably diverse picture, pointing to multiple ‘counter-forces’ that can push against the evolution of conventional sex roles, as my colleague John Dupré has argued.

Such supplements can include dehydroepiandrosterone (DHEA), and the herbal product Tribulus terrestris. However, a bill was passed in 2014 banning designer anabolic steroids. The effects of gradually lowering testosterone levels as men age have received increasing attention in recent years. High or low levels of testosterone can lead to dysfunction in the parts of the body normally regulated by the hormone. One study suggests that there’s a lower risk of aggressive prostate cancers for those on testosterone replacement therapy, but more research is needed.

And while it’s true that men’s testosterone levels gradually decline as they age, there are cases where testosterone levels can be abnormally low and cause negative symptoms. If necessary, there are ways to increase testosterone through lifestyle changes and hormone replacement therapy. Once again, as with males, the use of supplemental testosterone hormone in females provides many of the same results. Women can expect better body composition thanks to increased fat burning, weight loss, and improved muscle mass. Stronger bones and muscles reduce the risk of age-related fractures. The hormone testosterone is responsible for red blood cell production in the bone marrow.
