Background: The male antifertility activity of Gossypol, the active ingredient of cotton seed, inspired the idea for development of an agent with male contraceptive activity. The result of subsequent studies lead to the discovery of several class of compounds with antifertility activity. In this study the antifertility activity of iso-Propyl and iso-Butyl derivatives of dihydropridine were evaluated.
Methods: The two aforementioned compounds were administered subcutaneously in (10 mg/kg/day) dose to male rats. The animals were treated and kept according to the TUMS committee recommendations on ethical and animal maintenance considerations. Sixty days after the first injection the following fertility and histological indices were evaluated, animal’s body weight difference (B.W.D), sperms motility, sperm viability, ESR (epididymal sperm reserve), DSP (daily sperm production), serum testosterone concentration, fertility index, GSI (gonado somatic index). Histological indices are respectively the area and circumference of seminiferous tubules, each testis and their crosswise dissections, the diameter of seminiferous tubules and the number of seminiferous tubules per square millimeter, that were determined.
Results: The values of the two test groups were determined and compared with the results of normal group that were using normal saline only and the blank that were receiving propyllenglycol only.
Conclusion: The significant inhibitive activity of candidate compounds on animal's physiologic indices were in accordance of our pervious estimation of compounds activity as (lead compound) for synthesis and preparation of new compounds with male contraceptive activity
