Prenatal treatment of congenital adrenal hyperplasia.

Prenatal diagnosis of congenital adrenal hyperplasia (CAH) is accurate and prenatal therapy is effective in significantly reducing or even eliminating virilization of females affected by CAH, sparing these children the consequences of genital surgery, sex missassignment and gender confusion. However, both the physical and psychological development of these children and the possibility of long-range adverse effects in the mothers need to be evaluated further. Prospective multicentre studies covering several decades are being designed.
