Congenital atresia of the uterine cervix and vagina: three cases.

The outcome of surgical intervention in three patients with congenital atresia of the cervix seen at our institution is reviewed. The results are compared with results in all cases reported in the literature. The embryologic mechanisms that are involved in lower Müllerian tract formation are discussed. In our opinion surgery to preserve fertility in these patients offers little chance of success at great risk and should not be attempted.
