Propecia treats men with male patterned baldness. Proscar treats enlarged prostates. Proscar  and Propecia are medications  and  brand names for finasteride, a synthetic antiandrogen that prevents enzymes from converting testosterone to Dihydrotestosterone (DHT), also referred to as an androgen or male sex hormone.  Propecia and Proscar block DHT. High levels of DHT are believed to be responsible for an enlarged prostate and prostate cancer. Additionally, it is believed that DHT causes hair follicles.

Both Propecia and Proscar are medications manufactured by Merck & Co. Testosterone is the main androgen in men and is needed for normal sperm, bone, and muscle development in addition to potency and libido. DHT has no physiological role in the adult male but is involved in producing prostate enlargement, balding, and body hair. Merck & Co. found that DHT was a causative factor in male pattern baldness when treating men with enlarged prostates with Proscar and created Propecia.

Finasteride is a type II5-Alpha reductase inhibitor that prevents the conversion of androgen testosterone to DHT. The mechanism of Propecia is quite simple because it inhibits the production of testosterone, a male sex hormone, and so it decreases the problems of elevated testosterone or testosterone sensitivity while creating the same problems as if a man had low testosterone.

Until recently, it was believed that there were minimal side effects from Propecia and Proscar. New information suggests that Proscar and Propecia may impair sexual function, sexual desire, and erectile function. The sexual dysfunction side effects from Propecia and Proscar may be permanent and irreversible.
