Look into diindolylmethane (DIM) supplement for men and women. What I understand how it works is that It acts as an estrogen blocker (aromatase inhibitor) and there is a lot of estrogen hormones/mimics of estrogen in the food supply. By blocking that, testosterone is freed in the body to be used. It comes from cruciferous vegetables.
