MALES: Progesterone may help to inhibit the conversion of androgens to estrogens as well as serve as a precursor for cortisol synthesis when cortisol levels are low. Progesterone is also a natural inhibitor of 5-alpha reductase, which converts testosterone into the more potent androgen, dihydrotestosterone (DHT) within target cells. Excessive levels of estrogens and DHT in combination are thought to play a role in stimulating the growth of prostate cancer cells. Because progesterone is an antagonist of both hormones it may have benefit in lowering risk for prostate cancer. Progesterone PIL: www.askdrskip.com/progesterone/
