Effect of cadmium on the spermatogenesis of Rana hexadactyla Lesson.
A single subcutaneous injection of 0.5 mg cadmium chloride in Amphibian Ringer solution caused a significant decrease in secondary spermatogonial and primary spermatocytic stages in the semineferous tubules of frogs in 7 days. B3 cells of adenohypophysis and the activities of delta 5-3 beta-hydroxy steroid dehydrogenase and 17 beta-dehydrogenase in the Leydig cells were significantly increased in the same period. There were no significant changes in 3 days.
