lerian ducts along the lateral aspect of the gonads in conjunction with simultaneous regression of the mesonephric ducts. Interruption of müllerian duct development during this time gives rise to aplasia or hypoplasia of the vagina, cervix, or uterus. Müllerian duct growth is accompanied by mid-line migration and fusion of these paired ducts to In the absence of Mullerian Inhibitory Factor these ducts proliferate and grow extending from the vaginal plate on the wall of the urogenital sinus to lie beside the developing ovary. The paired ducts begin to fuse from the vaginal plate end, forming the primordial body of the uterus and the unfused lateral arms form the uterine tubes . 2018-06-19 2020-03-29 1: Anti-Mullerian Hormone A glycoprotein that causes regression of MULLERIAN DUCTS. It is produced by SERTOLI CELLS of the TESTES. In the absence of this hormone, the Mullerian ducts develop into structures of the female reproductive tract.

In the absence of Mullerian Inhibitory Factor these ducts proliferate and grow extending from the vaginal plate on the wall of the urogenital sinus to lie beside the developing ovary. The paired ducts begin to fuse from the vaginal plate end, forming the primordial body of the uterus and the unfused lateral arms form the uterine tubes . The Wolffian duct will degrade, and the Mullerian duct will develop into female sex organs such as the uterus, fallopian tubes and part of the vagina.

The etiologic heterogeneity of Mullerian fusion defects is considered. Fertil Steril 40:80, 1983 Incomplete Mullerian fusion results from par­ tial or complete failure of the Mullerian ducts to fuse or canalize.
