Human embryos contain both mesonephric (Wolffian) and paramesonephric (Müllerian) ducts. The presence of testosterone and anti-Müllerian hormone in males cause the mesonephric ducts to develop into the seminal vesicles, epididymis, vas deferens, and efferent ducts of the testis and the paramesonephric ducts to regress into the appendix epididymis. The absence of these hormones in females cause the paramesonephric ducts to develop into the fallopian tubes, uterus, cervix, and upper vagina and the mesonephric ducts to regress into the mesonephric remnants, located in the lateral walls of the fallopian tube, uterus, cervix, and upper vagina. 851209 IJSXXX10.1177/1066896919851209International Journal of Surgical PathologyHernandez and Marcus research-article2019
