"In some ways, the symptoms of low testosterone can be similar to what women experience when they begin menopause," says Dr. Hakim. Testosterone belongs to a group of sex hormones called androgens that are responsible for starting puberty, the development of your sexual reproductive system and your ability to reproduce. "There are many factors at play that have an impact on testosterone production and men with hypogonadism often present with many different signs or symptoms," says Dr. Hakim.

Athletes are allowed to compete in the restricted events with medical suppression of testosterone (by contraceptive injections or pills, or physical castration), although in practice many have chosen to switch to unaffected events, most notably the 200 m. Most men feel improvement in symptoms within four to six weeks of taking testosterone replacement therapy, although changes like increases in muscle mass may take from three to six months. And any activity that promotes good health will be beneficial to your biological functions, like producing testosterone and other hormones.

The study found that there was no correlation between endogenous testosterone and sporting performance for women in most events. The authors noted that there is "complete overlap of the range of concentrations seen between the genders. This shows that the recent decision of the IOC and IAAF to limit participation in elite events to women with a 'normal' serum testosterone is unsustainable." However, a study of endocrine profiles in 693 elite female and male athletes published in 2014 found that only 13.7% of the elite female athletes had high levels of testosterone while as many as 16.5% of the elite male athletes had low levels of testosterone.
