La descente testiculaire

Testicular descent

Resume

La formation des gonades est intimement liée à celle du mésonéphros ou rein intermédiaire. Les testicules apparaissent dans la région dorsale de l’embryon, en arrière de la cavité coelomique abdominale. Pour gagner leur situation définitive les testicules descendent dans la cavité pelvienne, franchissent la paroi abdominale par l’anneau inguinal et se fixent au fond de la poche scrotale. La migration testiculaire se fait ainsi en trois phases successives ayant chacune leur mécanisme propre. Les organes annexés aux testicules (épididyme et déférent) et surtout les ligaments qui les relient à la paroi (gubernaculum testis) jouent un rôle essentiel dans ces déplacements.

Abstract

Gonadal development is intimately linked to that of the mesonephros. The primordial testes differentiate in the dorsal region of the embryonic abdomen, behind the coelomic cavity. To reach their final location within the scrotum, the testes descend into the pelvis, pass through the abdominal wall by the inguinal canal, and attach to the base of the scrotal pouch. Testicular migration therefore comprises three stages, each requiring its own mecanism (s). The genital ducts (epididymis, vas deferens) and ligament which attaches the testis to the scrotal wall (gubernaculum testis) certainly play an essential role in these migratory events. The first phase is quite passive, associated with the growth of the abdominal cavity. In the second phase, the gubernaculum enlarges and shortens, pulling the testis through the inguinal canal. Finally, the gubernaculum, as a short, fibrous ligament, attaches the testis to the scrotal wall.
