When these receptors are blocked or knocked out in mice within the paramesonephric duct mesenchyme, AMH-induced paramesonephric duct regression is lost. During this time primordial germ cells migrate from the yolk sac to the gonadal ridge ; a region of mesenchyme arising from, and running parallel with, the mesonephros.

The caudal parts of the paramesonephric ducts fuse into a single tube, known as the uterovaginal primordiumbefore flowing into the dorsal aspect of the urogenital sinus at the sinus tubercle directly medial to the mesonephric ducts.


Wolffian structures are male urogenital structures that include the epididymisvas deferensand seminal vesicles that differentiate from this structure. The Journal of Obstetrics and Gynaecology Research. Discoveries in Molecular, Cellular, and Evolutionary Biology.

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.

In the absence of the Wnta7a within the duct epithelium as the ducts regress, ductal AMHR-II expression is lost, and residual paramesonephric ducts would be retained in males, throwing off the urogenital system.

In both the male and the female the mesonephric duct develops into the trigone of urinary bladdera part of the bladder wall.
