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.
Despite the reptile heart have no union with pericardium and be anchored by gubernaculum cords ligament in some groups (JACOBSON, 2007), the exact origin of extracardiac fluid can not be determined since no hyperechoic interface was observed concurrently (MARTORELL et al., 2004), even when there was liquid between liver lobes.
Usually, as the puppy grows--initially, in utero, and then, after his birth--his testicles are gradually pulled from the abdomen, through the inguinal canal (a passageway through the abdominal wall), and into the scrotum by the gubernaculum, a ligamentous cord connecting the testes to the scrotum.
Using light microscopy, the nematodes were identified as spiruroids of the genus Procyrnea (Spiruroidea: Habronematidae) according to the following characteristics: the body presented fine transverse striations, buccal region consisting of two pseudolabia and dorsal and ventral labia each consisted of two submedial lobels and small teeth on the border of pseudolabia, thick-walled buccal cavity, esophagus divided into a short anterior muscular part and a long posterior glandular part, a coiled male tail with caudal alae, unequal spicules, presence of a gubernaculum, and a vulva in females near their midbody (Chabaud, 1975).

The gubernaculum on the left side was cut to displace the testis into the abdomen, and the inguinal canal was closed.
