Development of male reproductive system video

Male reproductive system

Primordial sex cells are formed in the yolk sac in the pre-somite embryo. They migrate from this position to the medial aspect of the mesonephric ridge. The epithelium of the mesonephric ridge then proliferates and forms its own ridge called the genital ridge. Two ducts are now recognised as the Wolffian or mesonephric duct and the paramesonephric duct (Mullerian ducts) bilaterally. The mesonephric duct is associated with the mesonephros and the developing kidney system. In the male, as soon as the sex cells arrive, the epithelium of the genital ridge form sex cords which becomes cut off from the surface epithelium and are linked to the mesonephric tubular system to form the primitive seminiferous tubules of the testis. This allows the mesonephric duct to be the main duct that differentiates into the definitive male reproductive system with the formation of the duct of epidydimis, the vas deferens, and ejaculatory duct. The Mullerian tubercle which is formed at the junction of the two ducts with the urogenital sinus in both sexes becomes the seminal colliculus of the prostate. The paramesonephric duct degenerates in the male but forms the ductal system in the female, but may also form vestigial structures in the male such as appendix of testis and epidydimis. The paradydimis and aberrant ductules are formed from the mesonephric tubules  which persists.
