title: Effect of (-)- and (+)-gossypol on fertility in male rats.
abstract: (+)-Gossypol has neither antifertility effect nor toxicity at the dosage of 30 mg/kg orally for 14 days in male rats, but slight damage was found in the germinal epithelium of the testis in animals dosed for 4 weeks. (-)-Gossypol at 30 mg/kg orally for 7 days clearly had an antifertility effect in male rats. It appears that (-)-gossypol is the active stereoisomer of racemic gossypol.
