DHT is necessary for normal development of the genitalia of the male fetus. Because Proscar inhibits the conversion of Test to DHT, it could cause abnormal development of the genitalia in a male fetus. Doesn't take much in rats, but no one knows what exposure is necessary in humans to cause problems. Bottom line, if there is a possibility of pregnancy, don't use finasteride. There have been some studies done in women (Italy) using Proscar for excessive hair growth. It is effective and free of sides, but the pregnancy issue is always a concern.
