Body fat and testosterone related?

Testosterone. The amount of body fat can influence the ratio between testosterone and estrogen in your body. Adipose tissue (fat) has the ability to convert testosterone to estrogen. @drhtay.
Fat lowers T. New studies have shown that overweight men tend to have lower testosterone levels. This compounds the problem that fat cells (in both men and women) produce estrogen, and therefore, estrogen side-effects. In men, this can cause nipple tenderness and breast development.
