Involvement of prostaglandin in the antifertility effects of gossypol.
This study was undertaken to determine the effects of gossypol alone and gossypol in combination with prostaglandin and aspirin. Rats were administered gossypol (40 mg/kg/day), gossypol and prostaglandin (PGF2 alpha-2 mg/kg/day), gossypol and aspirin (300 mg/kg) for 4 weeks. A marked effect of the gossypol-prostaglandin combination was observed on sperm motility and spermatogenesis. The effect of the gossypol-aspirin combination was less pronounced. The ratio of body weight to testicular and epididymal weights between the different groups showed no marked difference. No effect of drug treatment on plasma testosterone, LH and FSH was observed. The data presented in this paper suggest that prostaglandin plays an important role in the antifertility effects of gossypol.
