From Wikipedia, the free encyclopedia.
Wolffian duct (also known as Archinephric Duct, Leydig's duct, and the mesonephric duct) is an organ in humans prior to birth. It carries urine from the kidney.
In a male, it develops into the vas deferens; in a female, into the epoophoron.
It is named after Kaspar Friedrich Wolff.
