Effect of gossypol on rats maintained on protein deficient and low potassium diets.
Sexually mature male albino rats were divided into four groups of 5 animals each. Animals of group I served as control, whereas animals of group II received gossypol (20 mg/kg body weight/day) for 45 days. Animals of groups III and IV were maintained on protein deficient diet. Animals of group IV received 20 mg/kg gossypol in addition to the protein deficient diet. Animals of group III and IV received protein deficient diet for 45 days before initiating gossypol treatment. The total period of maintaining the animals on protein deficient diet was 90 days. In another experiment, the same experimental protocol was followed except that the animals were maintained on low potassium diet instead of protein deficient diet. A significant decrease in body weight of animals was observed following protein deficient and gossypol (group IV) treatment. Testis weight decreased significantly in the animals of group III (protein deficient) and group IV (protein deficient + gossypol). Similar observations were made in the animals maintained on low potassium diet. In both the experiments, sperm motility was reduced significantly. Histologically, in the testis of animals of group IV (protein deficient + gossypol) almost all the tubules were disorganised and vacuolated and total arrest of spermatogenesis could be observed in majority of the tubules.
