Discoveries in Molecular, Cellular, and Evolutionary Biology. The paramesonephric ducts and the mesonephric ducts share a majority of the same mesenchyme due to Hox gene expression.

Transverse section of human embryo eight and a half to nine weeks old. Due to improved surgical instruments and technique women with paramesonephric duct anomalies can have normal conductoz relations. In contrast, the paramesonephric ducts begin to proliferate and differentiate in a cranial-caudal progression to form the aforementioned structures.

Wolffian structures are male urogenital structures that include the epididymisvas deferensand seminal vesicles that differentiate from this structure. During this time, the single-layered paramesonephric duct epithelium differentiates into other structures, ranging from the ciliated coneuctos epithelium in the uterine tube to stratified squamous epithelium in the vagina.
