چکیده
BACKGROUND In this study we aimed to evaluate the impact of chronic exposure to the Gly-phosate (GP) on rat's testicular tissue and sperm parameters. OBJECTIVE Testicular tissue, morphology of sperms and testosterone level in serum of mature male rats were analyzed. MATERIALS AND METHODS Animals were divided into two test and control-sham groups. The test group was subdivided into 4 groups (10, 20, 30 and 40 days GP administrated). Each test group (n=8) received the compound at dose of 125 mg/kg, once a day, orally for 40 days while control-sham group (n=16) received the corn oil (0.2 ml/day). RESULTS Microscopic analyses revealed increased thickness of tunica albuginea, obvious edema in sub-capsular and interstitial connective tissue, atrophied seminiferous tubules, arrested spermatogenesis, negative tubular differentiation and repopulation indexes, decreased Leydig cells/mm(2) of interstitial tissue, hypertrophy and cytoplasmic granulation of Leydig cells, elevated death, immature sperm and increased immotile and abnormal sperm percentage. The carbohydrate ratio was reduced in first three layers of the germinal epithelium (GE) cytoplasm. The upper layers of the GE series were manifested with low rate of lipid accumulation in cytoplasm, while the cells which were located in first layers were revealed with higher amount of lipid foci. Hematological investigations showed significant (p<0.05) decreasing of testosterone level in serum. CONCLUSION The current data provide inclusive histological feature of chronic exposure against GP with emphasizing on reproductive disorders including histological adverse effect on the testicular tissue, spermatogenesis, sperm viability and abnormality which potentially can cause infertility.

In this investigation, diabetes was induced in adult male Sprague-Dawley rats by single intraperitoneal injection of streptozotocin (STZ) at 45 mg kg-1 of body weight. A group comprised of 8 diabetic rats was treated with metformin at 100 mg kg-1 of body weight for reducing the elevated blood glucose level. The results revealed that, in the untreated diabetic rats, the body and testicular weigh...

Effects of camphor on histomorphometric and histochemical parameters of testicular tissue in mice
Background: In traditional medicine of some Asian countries it is believed that camphor could act as a sexual depressant. However, limited studies have been published on this issue. OBJECTIVES: In the current study, effects of camphor on testes, sperm and serum factors, and roles of vitamin E as antioxidant in treatment of toxicity of camphor for testes were studied. METHODS: Fifty adult male m...
