چکیده
Methods Thirty-two mature male rats were divided into two control and test groups. The experimental diabetes (50 mg kg−1 streptozotocin, ip) was induced in test group andsubdivided into non-treated diabetic, 300 and 600 mg kg−1 omega-3-treated (orally by gavage) groups. The rats in control group received 0.5 ml saline using intra gastric gavage. Following 45 days, general histopathological changes, serum level of testosterone, inhibin B, glucose, and sperm parameters, testicular total antioxidant capacity (TAC) and malondialdehyde (MDA) content were analyzed. The mitochondriadependent apoptosis was investigated by assessing the Bcl-2 and caspase-3 expression as well asDNA fragmentation. Finally, the in vitro fertilization (IVF) potential was examined by evaluating preimplantation embryo developing.Results: The omega-3 signifcantlyameliorated the diabetes-induced histological damages, diminished serum level of glucose, testicular MDA content, and enhanced the serum testosterone, inhibin B and testicular TAC. The animals in omega-3-treated groups exhibited a significant (p < 0.05) up-regulation in Bcl-2, as well as remarkable (p < 0.05) down-regulation incaspase-3 expression compared to non-treated diabetic rats.Conclusion Our data showed that the omega-3 (especially at 600 mg kg−1dose level) effectively ameliorates the experimental diabetesinduced infertility in rats by up regulating the testicular endocrine and antioxidant statuses, preventing mitochondria-dependent apoptosispathway and potentially improving the sperm quality.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
