title: Testicular vasomotion in different mammals.
abstract: Vasomotion is a rhythmical variation in arterial blood flow present in many different organs among them the rat testis. Vasomotion is suggested to play an important role for the transvascular fluid exchange and the exchange of nutrients over the capillary wall as well as the formation of interstitial fluid. The present study was undertaken to elucidate whether vasomotion is present in the testes of different species independent of their anatomical vascular topography. Blood flow in the testes of mouse, brush-tailed possum, tammar wallaby, ram and human was investigated by using a laser Doppler flowmeter. Vasomotion was found in all the species investigated.
