The development of the wolffian/epididymal duct is crucial for proper function and, therefore, male fertility the development of the epididymis is complex the initial stages form as a transient embryonic kidney then the mesonephros is formed, which in turn undergoes extensive morphogenesis under the influence of androgens and growth.

During the development of many internal organs, a single epithelial tubule undergoes repetitive deformation and generates a complex but well-organized pattern, such as tree-like branching or coiling, and it has been shown that tubular patterning processes are remarkably stereotypical and reproducible (joseph et al, 2009 x development and morphogenesis of the wolffian/epididymal duct. Hinton lab august 18, 2015 by our research focuses on the morphogenic events that allow the wolffian (epididymal) duct to elongate and coil without proper.
