ABSTRACT
The effect of anti-follicular stimulating hormone [FSH] on testicular lipid and the specific activity of testicular enzymes of the isocitrate dehydrogenase [ICDH], pyruvate/malate dehydrogenase [MDH] and malic enzyme involved in lipogenesis were studied in mature bonnet monkeys, Macaca radiata. Immunization of monkey with anti-FSH for 24 days did not produce any significant changes in the body weight, organ weight and pituitary weight. Testicular isocitrate dehydrogenase [ICDH] and malic enzyme activities were decreased significantly but MDH activity was stimulated by anti-FSH treatment. Testicular total lipid, phospholipid and cholesterol, were not altered significantly by the Anti-FSH treatment. Increased level of free cholesterol were also observed after FSH treatment. Among glyceride glycerol sub classes, triacyl glycerol showed a significant increase. Among testicular phospholipid classes, phosphatidyl inositol was markedly decreased by anti-FSH immunization. Data on serum hormonal profile, shows that there were no alteration in serum testosterone, prolactin [PRL] and luteinizing hormones [LH] but FSH was significantly decreased. The present study reveals that immunization with anti-FSH has significant effect on different class of testicular lipids and pyruvate malate enzymes cycle
