Antifertility plant products: testicular cell population dynamicsfollowing solasodine (C27H43O2N) administration in rhesus monkey (Macaca mulatta).
Solasodine obtained from the Solanum xanthocarpum berries was administered to Rhesus monkeys for 150 days to evaluate their effect on testicular cell population dynamics. Solasodine brings about an interference with spermiogenesis at the stage XII of late spermatids. The spermatids were decreased by 69% (P less than 0.001). No significant change was found in the population of spermatogonia/primary and secondary spermatocytes. The production of immature and mature Leydig cells were decreased by 60.4% and 41.6% respectively. A significant decrease in cauda sperm count (Control: 83.1 +/- 6.3; Solasodine 1.21 +/- 0.3 million/ml) was noticed. The testicular protein, sialic acid and glycogen contents were depleted following solasodine treatments to rhesus monkeys. Bioassay studies showed the antiandrogenic nature of the compound.

Reversible chemical sterilization: effects of cyclohexanol administration on the testes and epididymides of male rabbit.
Cyclohexanol administration (25 mg/kg/day orally for 40 days) produced a brief period of infertility in rabbits by inhibiting the process of spermatogenesis at the spermatocyte and spermatid levels. Seminiferous tubule and Leydig cell nuclear dimensions were reduced. The lumen of epididymides and ductus deferens were devoid of spermatozoa. Cyclohexanol administration reduced the concentrations of RNA, protein, sialic acid and glycogen in the testes and epididymides, whereas the total cholesterol concentration of the testes was elevated. Depletion of adrenal ascorbic acid was conspicuous. Moderate elevation of serum cholesterol, phospholipids, triglycerides, bilirubin, and pyruvate transaminase were recorded. Histopathological examination of liver did not show any damage. Leydig cell impairment and decreased production of RNA and sialic acid in the testes returned to subnormal values after cessation of cyclohexanol treatment for 70 days. Normal spermatogenesis was seen after 10 weeks of recovery period.
