The mesonephric duct, also known as the Wolffian duct, archinephric duct, Leydig's duct or nephric duct, is a paired organ that develops in the early stages of embryonic development in humans and other mammals. It is an important structure that plays a critical role in the formation of male reproductive organs.

The Müllerian ducts only develop in the absence of anti-Müllerian hormone, where the Wolffian ducts regress. [citation needed] Development of the female reproductive tract begins at approximately week 8 of embryonic development, and development of the Müllerian duct system is typically complete by the end of the first trimester.

Embryos are formed with Wolffian and Mullerian ducts, which will either become the male or female reproductive tract, respectively. [8] In a male embryo, the testicular cords will induce the development of the Wolffian duct into the vas deferens, epididymis and the seminal vesicle and cause the repression and regression of the Mullerian duct.

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. Many types of disorders can occur when this system is disrupted ranging from uterine and vaginal agenesis to the duplication of unwanted cells of the uterus and vagina.
The fetus has two sets of tubes which give rise to accessory reproductive organs - the (Wolffian) mesonephric ducts and the (Müllerian) paramesonephric ducts. Usually, the Wolffian duct gives rise to male reproductive organs (specifically the testicle, epididymis and vas deferens) while the Müllerian to female (the fallopian tubes, the uterus ...
