Müllerian duct
Quick Summary
The M\u00fcllerian duct, also known as the paramesonephric duct, is a structure that develops during prenatal development in both male and female embryos. In females, these ducts are crucial for forming the reproductive organs. The first two-thirds of the M\u00fcllerian ducts develop into the uterine tubes (fallopian tubes), while their lower ends fuse to form the uterus, cervix, and the upper part of the vagina.12
In male embryos, the M\u00fcllerian ducts typically degenerate due to the secretion of M\u00fcllerian inhibiting hormone by the developing testes. The Wolffian duct, in contrast, develops into the male genital tract. The development of these ducts is a critical part of sexual differentiation, influenced by genetic and hormonal factors.2

…male genital tract, and the Müllerian duct, the source of the female reproductive organs. During the third month of fetal development, the Sertoli cells of the testes of XY fetuses begin to secrete a substance called Müllerian inhibiting hormone. This causes the Müllerian ducts to atrophy instead of develop into…
