Résumé

The effect of different grades of hypobaric hypoxia for 48 hours was studied on spermatogenesis, Leydig cells and delta 5-3 beta-hydroxysteroid dehydrogenase activity in toad (Bufo melanostictus). Maximum inhibition of testicular activity was noted in 7,315 m exposed animals. The impairment of testicular function at high altitude is possibly due to inhibition of gonadotrophin secretion.
