Paramesonephric Duct

Data from the developing mouse showing the relationship between the mesonephric and paramesonephric ducts opening into the urogenital sinus.

The paramesonephric duct began as an infold of surface epithelium lying along the surface of the genital ridge. Estrogens, both maternal and fetal, stimulate its development and that eventually of the external female fetal genital structures.

In contrast, the mesonephric duct regresses, remnants of this duct may remain lying within the broad ligament.
