Morphology and histochemistry of male genital system was surveyed in spring, summer and fall. After collecting geckoes, they were weighted and SVL (Snout-vent length) were measured. After opening abdominal cavity, the genital system was exposed. Then testicular weight was measured and Gonadosomatic Index was calculated. Then, the genital system was fixed in 10% buffer neutral formalin and routine process of histology was done. The slides were stained with H&E, PAS and PAS-Alcian blue. Results revealed that, testis is active in spring and fall with significant seminiferous tubules enlargement. The epididymis is filled with sperms and the sexual segments in kidney are visible and significant. For the moderate climate in west of Iran, the reproductive cycle of A. elisae is seasonal and it depends on the temperature.

One of the treatments of this syndrome is using Insulin sensitive drugs. The main objective of this project is to analyze the effect of Repaglinide on the histomorphology of polycystic ovary. Materials & Methods: In this study, PCOS is induced by the injection of Testosterone Enanthate in immature mice aged five to seven weeks old for four weeks. Then, the mice were divided in to two groups of control and case. The control group had no injection. In the case group, each mouse received 30 μgr Repaglinide. Body weight, the ratio of ovary weight to body weight, and ovarian diameter were measured and the changes in histomorphology of the ovary, characteristics of ovarian tissue, and the number of follicles were investigated. TTest was used in this study (T-test, P0.05( . Results: The result revealed that Repaglinide had a reducing effect on body weight, the r...
