Research suggests that homosexuality is closely related to hormonal imbalances found in roughly 4 percent of all adults. True or False?
Both men and women produce testosterone, but levels of testosterone are generally higher in men than women. However, levels of testosterone in some XX females fall within the range of testosterone levels of XY men. This overlap has created controversy within women’s sports. Testosterone is known to increase muscle mass and enhance some types of athletic performance, so some people have suggested that women with naturally high testosterone have an unfair competitive advantage. In 2011, the International Association of Athletics Federations (IAAF) adopted a policy that limits levels of testosterone in women athletes, saying that women athletes must not have a blood testosterone concentration greater than 10 nanomoles per liter (nmol/L), a level typically seen in men. Some elite women athletes have natural testosterone levels above this limit and have challenged the policy. Do you think that it is fair for XX females with naturally high testosterone (levels typically found in XY males) to…
