Abstract

We studied the morphology of the spermatic funicle in goats according to their scrotum conformation.  Animals were divided into three experimental groups: I – non-bipartite scrotum; II - bipartite scrotum up to 50% of testicular length; and III – bipartite scrotum over 50% of testicular length. We evaluated the length of the spermatic funicle, cremaster muscle, the segment of the umbilical artery and spermatic funicle histology. In all groups the testicular artery was found to be single (95%) or divided (5%), surrounded by numerous veins without valves and varied and irregular diameters. In group I, the subcapsular adipose tissue was involving the veins. In groups II and III, this tissue was showed as plates surrounding the funicle, becoming thicker near the mesoductus, suggesting the presence of thermal insulation between the vessels and the vas deferens. We found that goats from group III showed greater length of funiculus (mean=10.25cm) and testicular artery (mean=152.80 cm), in comparison with groups I (8.06 and 103.25 cm) and II (8.60 and 121.80 cm). This may facilitate heat exchange between arterial and venous blood. The length of the cremaster muscle did not differ statistically (P>0.05) between groups I (19.37 cm), II (18.61) and III (20.06 cm).
