Microdissection and radiographic studies of the arterial vasculature of the human testes.

Conflicting and sparsely detailed reports concerning the arterial vasculature of the testes prompted us to study 51 human cadaveric testicles radiographically in order to document any interarterial communications. Twelve specimens were harvested from the pediatric age group and 39 from adult cadavers. Vascular communication was demonstrated between the testicular, cremasteric, and vasal arteries in all specimens studied. Large-caliber anastomotic channels were demonstrated between the testicular and vasal arteries in 87% of specimens. No discernible differences in these vascular communications were documented among adult, pediatric, and undescended testes.
