Processus vaginalis : ウィキペディア英語版 | Processus vaginalis
The processus vaginalis (or vaginal process) is an embryonic developmental outpouching of the peritoneum. It is present from around the 12th week of gestation, and commences as a peritoneal outpouching. ==Sex differences== In males, it precedes the testis in their descent down within the gubernaculum, and closes. This closure (also called ''fusion'') occurs at any point from a few weeks before birth, to a few weeks after birth. The remaining portion around the testes becomes the tunica vaginalis. If it does not close in females, it forms the canal of Nuck.
