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 internal genitalia consist of two accessory ducts: mesonephric ducts (male) and paramesonephric ducts (female). The mesonephric system is the precursor to the male genitalia and the paramesonephric to the female reproductive system. [8] As development proceeds, one of the pairs of ducts develops while the other regresses.

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.

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 term vagina is from Latin vāgīna, meaning "sheath" or "scabbard". [1] The vagina may also be referred to as the birth canal in the context of pregnancy and childbirth. [2] [3] Although by its dictionary and anatomical definitions, the term vagina refers exclusively to the specific internal structure, it is colloquially used to refer to the vulva or to both the vagina and vulva.
Gartner's duct is located in the uterus' broad ligament. Its position is parallel with the lateral uterine tube and lateral walls of vagina and cervix . The paired mesonephric ducts in the male , in contrast, go on to form the paired epididymides , vasa deferentia , ejaculatory ducts and seminal vesicles .
