Effect of Fresh and Frozen Semen on in vitro Fertilization and Subsequent Development of Goat Embryos
This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...متن کامل
Background Oxidative stress induced by cyclophosphamide (CP), as a chemotherapeutic agent, causes vulnerability of sperm and declining the fertility capacity. Then in this study the effect of crocin (saffron extract) on amelioration of these side effects was investigated. MaterialsAndMethods In this study 24 mice were divided in three groups (n=8). Control group received normal saline (0.2 ml/d...متن کامل
