The inguinal canal forms by mesenchyme condensation around the gubernaculum. During the first trimester, the gubernaculum extends from the testis to the labioscrotal fold, and the processus vaginalis and its fascial coverings form. A bilateral oblique defect in the abdominal wall develops during week 6 or 7 of gestation as the muscular wall develops around the gubernaculum. The processus vaginalis protrudes from the peritoneal cavity and lies anteriorly, laterally, and medially to the gubernaculum by week 8 of gestation.
