Will taking finasteride cause birth defects?
A. There is only a theoretical possibility that it can. The probability is close to nil. There has not been a single case report of a birth defect due to taking finasteride. The association of a lack of DHT and birth defects is that a woman who has a congenital severe deficiency of 5 alpha reductase can give birth to a male child with abnormalities of his urinary tract and present as a pseudohermaphrodite. It has not been demonstrated to be caused by taking finasteride either by the father or the mother. We have had many patients, whose wives have conceived while the father was taking finasteride without any reports of birth defects or any other complications. blue_top.
