Assisted reproductive technology makes it possible for some women that have paramesonephric duct anomalies to conceive and give birth to healthy babies. The caudal parts of the paramesonephric ducts fuse into a single tube, known as the uterovaginal primordiumbefore flowing into the ve aspect of the urogenital sinus at the sinus tubercle directly medial to the mesonephric ducts.
Sex determination and differentiation. The paramesonephric ducts play a critical role in the female reproductive tract and differentiate to form the uterine tubes, uterus, superior vagina as well as the uterine cervix. The epoophoron and Skene’s glands may be present. Through the use of Vecchietti and Mclndoe procedures women can carry out their ds activity.
