In the last six years I have seen 11 patients1 with more or less complete duplex anomalies of the uterovaginal tract, each of whom has had one or more pregnancies (a total of thirty-two). The present discussion applies strictly to the association of the two conditions; no attempt is made to present embryologic or purely gynecologic considerations, and my approach is from the clinical rather than from the academic side.

Briefly, duplex anomalies of the uterovaginal tract are due to (1) irregularities of fusion involving the normal junction of the müllerian ducts to form the symmetrical halves of the corpus of the uterus and (2) irregularities in canalization involving the urogenital sinus or lower uterine and vaginal tracts. The most common anomaly is simple uterus arcuatus, departing little from the normal contours and hence not as often important clinically. I have not included such cases.
