It concluded that female athletes with high testosterone levels have a significant competitive advantage over those with low testosterone levels in 400 m, 400 m hurdles, 800 m, hammer throw, and pole vault ...
This graph of "Acceptable Testosterone Levels in Females and Males Compared to a Hypothetical Athlete" shows a situation in which the hypothetical athlete above may be a female with hyperandrogenism, higher than normal levels of testosterone, and would be subjected to sex verification tests and possibly forced to undergo aggressive medical protocols.
‘We have high levels of testosterone in our 20s, but after the age of 30, levels naturally decline by approximately 1% per year - unless you have a surgically-induced menopause, during which ...
