Anomalies that develop within the paramesonephric duct system continue to puzzle and fascinate obstetricians and gynecologists. Due to a very broad range of anomalies it is very difficult to diagnose paramesonephric duct anomalies. The paramesonephric ducts play a critical role in the female reproductive tract and differentiate to form the uterine tubes, uterus, superior vagina as well as the uterine cervix.

Wolffian structures are male urogenital structures that include the epididymisvas deferensand cconductos vesicles that differentiate from this structure.

cconductos The caudal parts of the paramesonephric ducts fuse into a single tube, known as the uterovaginal primordiumbefore flowing into the dorsal aspect of the urogenital sinus at the sinus tubercle directly medial to the mesonephric ducts.

The paramesonephric ducts and the mesonephric ducts share a majority of the same mesenchyme due to Hox gene expression. In both the male and the female the mesonephric duct develops into the trigone of urinary bladdera part of the bladder wall. Discoveries in Molecular, Cellular, and Evolutionary Biology.

Development of the reproductive system. Anatomical terminology [ edit on Wikidata ]. In the absence of the Wnta7a within the duct epithelium as the ducts regress, ductal AMHR-II expression is lost, and residual paramesonephric ducts would be retained in males, throwing off the urogenital system. In females, the paramesonephric ducts give rise to the uterine tubes, uterus, and upper portion of the vagina, while the mesonephric ducts degenerate due to the absence of male androgens.

Most abnormalities are often recognized once the external genitalia is no longer masked and the internal reproductive organ abnormalities become revealed.
