For PMDS, ELISA tests can be used to determine the levels of AMH within the male individuals serum, but this is only effective before the individual reaches puberty as it normally increases during this period. PMDS patients display low levels of AMH within the serum, and low levels of testosterone. Treatment
The main form of treatment is laparotomy, a modern and minimally invasive type of surgery. Laparotomy properly positions the testes within the scrotum (orchidopexy) and remove Müllerian structures, the uterus and fallopian tubes. Occasionally they are unsalvageable if located high in the retroperitoneum. During this surgery, the uterus is usually removed and attempts made to dissect away Müllerian tissue from the vas deferens and epididymis to improve the chance of fertility. If the person has male gender identity and the testes cannot be retrieved, testosterone replacement will be usually necessary at puberty should the affected individual choose to pursue medical attention. Recently, laparoscopic hysterectomy is offered to patients as a solution to both improve the chances of fertility and to prevent the occurrence of neoplastic tissue formation. The surgery is recommended to be performed when the individual is between one and two years old, but usually done when less than one year old. Having a target age for surgery reduces the risks of damaging the vas deferens. The vas deferens is in close proximity to the Müllerian structures, and is sometimes lodged in the uterine wall.
The AMH receptors are on the Müllerian duct mesenchyme and transfer the apoptotic signal to the Müllerian epithelial cell, presumably via paracrine actors. The Wolffian ducts differentiate into epididymides, vasa deferentia and seminal vesicles under the influence of testosterone, produced by the fetal Leydig cells. Diagnosis
Persistent Müllerian duct syndrome (PMDS), also known as persistent oviduct syndrome, is a congenital disorder related to male sexual development. PMDS usually affects phenotypically normal male individuals with the karyotype (46, XY) and is a form of pseudohermaphroditism.The condition occurs in males and consists of normal-functioning reproductive organs and gonads, but also female reproductive organs such as the uterus and the fallopian tubes. The fetus has two sets of tubes which give rise to accessory reproductive organs - the (Wolffian) mesonephric ducts and the (Müllerian) paramesonephric ducts. Usually, the Wolffian duct gives rise to male reproductive organs (specifically the testicle, epididymis and vas deferens) while the Müllerian to female (the fallopian tubes, the uterus and the vagina), while the other duct regresses. In PMDS, an abnormality in the anti-Müllerian hormone signalling pathway causes the in-males-redundant Müllerian duct to persist and give rise to variously developed female reproductive organs.PMDS has various causes related to AMH or receptor abnormalities. For example, AMH has failed to synthesize, failed to release or was secreted at the wrong time. Normally, both the Müllerian and Wolffian ducts are present during the 7th week of gestation.
