The paramesonephric ducts and the mesonephric ducts share a majority of the same mesenchyme due to Hox gene expression. In both the male and the female the mesonephric duct develops into the trigone of urinary bladdera part of the bladder wall. Power will come from either a 6.

In the mature male, the function wolft this system is to store and mature spermand provide accessory semen fluid. The genes expressed play a critical role in mediating the regional characterization of structures found along the cranial-caudal axis of the female reproductive tract. Testosterone binds to and activates androgen receptoraffecting intracellular signals and modifying the expression of numerous genes.
