Effect of gossypol on few testicular enzymes in mature rats.

Effect of oral administration of gossypol acetic acid (15 mg/kg/day) for 10 weeks, on certain enzymes, which may be taken as markers for the different stages of spermatogenesis, was studied in male albino rats. Gossypol produced a significant decrease in hyaluronidase and sorbitol dehydrogenase, while no change was observed in beta-glucuronidase and acid phosphatase. A significant increase in the total lactate dehydrogenase activity was observed in the testis. The possible significance of these findings is discussed.
