Wolffian Duct

The Wolffian duct is an embryonic structure in developing embryos that plays a key role in forming the male reproductive system. In males, under the influence of certain hormones, it develops into structures like the epididymis, vas deferens, and seminal vesicles, which are involved in sperm storage and transport. In females, the Wolffian ducts typically regress and do not form significant structures. Their development is part of the process that determines along which path the reproductive organs will form, making them essential for proper sexual differentiation during early development.
