Typically, testosterone levels in men are around 15 times higher than in women. In both women and men, it’s normal for testosterone levels to drop with age — starting at about age 30 in men ...

When compared with women with lower levels of the hormone free testosterone (fT), women with the highest fT levels performed significantly better in the 400 m, 400 m hurdles, 800 m, hammer throw, and pole vault with margins of 2.73%, 2.78%, 1.78%, 4.53%, and 2.94%, respectively. Such a pattern was not found in any of the male athletic events.
Free Androgen Index (FAI) is a ratio used to determine abnormal androgen status in humans. The ratio is the total testosterone level divided by the sex hormone binding globulin (SHBG) level, and then multiplying by a constant, usually 100. The concentrations of testosterone and SHBG are normally measured in nanomols per liter. FAI has no unit.
Testosterone is an essential hormone for both men and women, playing an important role in muscle growth and cognitive function. Low levels of the hormone can lead to changes in mood, cognition and ...
