[The structural-functional characteristics of the blood vessels of the testis and its tunicae]. / Strukturno-funktsional'ni osoblyvosti krovonosnykh sudyn iaiechka ta ioho obolonok.

The structure of arteries and veins of a testis and its capsules was studied on 53 preparations of human testes (men aged from 25 to 30 years) and on 43 preparations of rat testes (mature Wistar rats weighing 150-200 g) using the methods of vessels' injection, angiography, morphometry and silver impregnation. It has been ascertained that structure of testicular capsule arteries, veins and microvessels has specific features. The role of these blood vessels in thermoregulation of testis is discussed.
