Ligustrum fruit extract wasgiven by gastric gavage at a dose of crude drug 30 g·kg^(-1)·d^(-1) for 110 days. The serum gonadadotropic hormones andtestosterone were determined on d 60 and testicular histology examined on d 110. Results: In the control diabeticrats, the seminiferous tubules were dilated and the spermatogenic cells irregularly arranged. Spermatogenesis was arrest-ed with the number of spermatids highly reduced and spermatozoa not observed. In the treated rats, all types of sper-matogenic cells were practically normal. The serum luteinizing hormone (LH), follicle-stimulating hormone (FSH)and testosterone levels were higher in the treated than in the control rats, but the difference was insignificant. Conclu-sion: In experimental diabetic rats, ligustrum fruit extract protects the damaging effect of experimental diabetes onspermatogenesis. (Asian J Androl 2001 Mar; 3 : 71-73)展开更多
