Effects of Oxygen and Decreased Total Pressure on Testicular Function in the Rabbit

摘要

This investigation examined the effects of increased partial pressure of oxygen at reduced total pressure (380 mm. Hg) on testicular function in the rabbit. Ejaculates were collected with an artificial vagina. Ejaculate volume, sperm concentration, percentage of live sperm, percentage of sperm with normal morphology, and sperm motility were measured. At the end of the experimental period the rabbits were sacrificed and gonadal and epididymal sperm reserves were measured. Histologic studies were made on the pertinent organs. Changes were observed in testicular and other sexual functions, although the semen sample variables fell within normal range in all groups. All the rabbits remained healthy throughout the periods of exposure. (Author)
