With gentle traction on the testis, the most distal gubernacular attachment was divided with electric hook cautery, and gubernaculum was used as a handle for mobilizing the testis.
Origin, development and fate of the gubernaculum hunteri, processus vaginalis peritonei, and gonadal ligaments.
The anatomic risk factor associated with neonatal torsion is lack of fixation of the gubernaculum. However, other risk factors for neonatal torsion include high birth weight, late birth week, breech presentation, and trauma from labor (Basta et al., 2015; Mano, Livne, Nevo, Sivan, & Ben-Meir, 2013; Sharp et al., 2013).
Passage through the inguinal canal is aided by both the processus vaginalis and the shortening of the gubernaculum. The testes remain retroperitoneal throughout their descent, but are intimately associated with the posterior wall of the processus vaginalis.
Inguinal canal development goes through complex events involving the gubernaculum and the process vaginalis.
