Sertoli cells also ensure regression of mullerian ducts via secretion of anti mullerian and inhibin hormones (3).
Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a rare anomaly in females that affects 1 in 5000 live births (1,2), in which there is dysgenesis of the Mullerian ducts leading to failure of development of the uterus and vagina.
The female reproductive tract develops from a pair of Mullerian ducts that form the fallopian tube, uterus, cervix, and the upper two-thirds of the vagina.
Transverse vaginal septum is a rare condition that results from incomplete fusion between the vaginal components of the mullerian ducts and the urogenital sinus.
This hormone binds to the AMH type II receptor, a single transmembrane protein (TP) with serine-threonine kinase activity, expressed on target organs such as Mullerian ducts, Sertoli and Leydig cells of testis and granulosa cells of the ovary.
Mammals initiate embryonic development without phenotypic sexual differentiation, and an ovary is not required for the female phenotype, but a testicle and the production of androgenic hormones are essential for the development of a male phenotype, since both, Wolff and the Mullerian ducts are found in sexually undifferentiated embryos.
DISCUSSION: Rudimentary Horn in a unicornuate uterus results from failure of complete development of one of the Mullerian ducts and incomplete fusion with contralateral side.
Without AMH, the Mullerian ducts develop into normal internal female organs (uterus, fallopian tubes, cervix and upper vagina).
Uterine malformations make up a diverse group of congenital anomalies that can result from various alterations in the normal development of the Mullerian ducts, including underdevelopment of one or both Mullerian ducts, disorders in Mullerian duct fusion, and alterations in septum reabsorption.
In normal fetal sex organ development, the Wolffian and Mullerian ducts give rise to male and female internal sex organs, respectively.
Embryologically, Mullerian ducts in the female develop into vagina, uterus and oviducts.
Uterus didelphys results from the arrest of midline fusion of Mullerian ducts and is characterized by complete/ partial duplication of the uterus, cervix, and vagina.
