Effect of depot medroxyprogesterone acetate and testosterone ananthate on the testis of albino rats: ultrastructural and biochemical studies.
Male albino rats were treated with depot medroxyprogesterone acetate (1 mg/animal/day) + testosterone ananthate (100 micrograms/100 g body weight/day) for 30 and 60 days. After 30 days of treatment, all the testicular enzymes like beta-glucuronidase, hyaluronidase, sorbitol dehydrogenase, lactate dehydrogenase, acid and alkaline phosphatase, registered non-significant decrease in their values. Fifty percent of the treated animals achieved sterility after 30 days of treatment. After 60 days of treatment the testis showed degenerative changes in Golgi phase and late spermatids. Changes in the Golgi phase spermatids were related with degeneration of the nuclear membrane. Changes in the late phase spermatids included mitochondrial hypertrophy of the midpieces, membrane lysis, absence of cristae and degeneration of annulus leading to detachment of tail. Cytoplasm of luminal area displayed hypertrophied mitochondria devoid of cristae, prominent appearance of Golgi bodies, intense lysosomal activity and ample vacuolation. Tail fragments of degenerated spermatids prevailed in luminal cytoplasm. Except for beta-glucuronidase which registered a significant decrease, levels of all the other testicular enzymes, viz. hyaluronidase, lactate dehydrogenase, sorbitol dehydrogenase, acid phosphatase and alkaline phosphatase were within their control limits. The ultrastructural and biochemical changes are correlated.
