Soy and Estrogen
One common misconception is that soy contains estrogen and can have adverse hormonal effects on men’s health. The truth is soy contains isoflavones, not estrogen.*
Recent studies have shown soy and isoflavones to have no adverse effect to men’s health, and more specifically no adverse effect to sperm counts and testosterone levels.
