Compensatory development of a patent vascular supply to the testis after intra-abdominal transection of its main blood vessels.
The compensatory development of testicular vascular supply was studied in the pig after intra-abdominal transection of the testicular artery and vein at a young age (2 months). Post-pubertally (6 1/2 months) in these animals, normal spermatogenic epithelium and testosterone values were found. Functionally important anastomoses developed from latent connections between the vasal and testicular arteries at the coiled part of the latter and on the surface of the testis. Blood supply to the testes of operated animals reached 80% of values measured in control animals.
