Müllerian abnormalities in fertile women and recurrent aborters.

Ninety-six women with recurrent first-trimester spontaneous abortions underwent hysterosalpingography to rule out müllerian abnormalities, both congenital and acquired. Results were compared with those in 96 women who had undergone hysterosalpingography before artificial insemination by donor and subsequently had a full-term, normal delivery. The patients with two recurrent, consecutive abortions had müllerian abnormalities similar to those in women with three consecutive abortions; however, they had different müllerian abnormalities than did the control group. Congenital and acquired malformations seen most often in patients with recurrent abortions were septate, arcuate and bicornuate uteri and incompetent cervical os. Pelvic examination did not discriminate between patients with recurrent abortions and the control group.
