Abstract Studies have been carried out on 18 adult male rabbits divided into three groups. One group (hypoxic) was exposed to a simulated altitude (6,060 m for 6 h daily for 21 days), the second group was exposed to the same altitude plus cold (−5°C) for the same duration, and the third acted as control. The results showed no difference in the body weight of the three groups, but the weights of the sex organs in the exposed groups were significantly reduced. In both these groups the number, motility and survival time of spermatozoa decreased significantly; the sex organs showed atrophy on histological examination; and there was an increase in the alkaline and acid phosphatase activity and cholesterol concentration, and a fall in GPC level. These changes were more marked in the cold plus altitude group than in the group exposed to altitude alone. It has been concluded that hypoxia affects not only the testis but also the epididymis and the vas deferens. The spermatozoal quality of rabbits deteriorates. When cold and hypoxia are combined, their effects are additive.
