P-214: The Rate of In Vitro Oocyte Maturation,Fertilization and Embryo Development in Presence of Melatonin in Mice
Background: It is important to protect oocytes and embryos from oxidative stress in the culture medium. Melatonin has been shown to be a direct free radical scavenger. Therefore, effect of melatonin during in vitro oocyte maturation (IVM), fertilization and embryo development of mouse oocytes was evaluated. Materials and Methods: Oocytes from supper-ovulated mouse were divided to two groups: cu...
متن کاملThe effect of varicocele ligation on oocyte fertilization and pregnancy after failure of fertilization in in vitro fertilization-embryo transfer.
Although varicocelectomy is generally believed to improve semen quality and the hamster egg penetration assay, these parameters do not correlate well with in vitro fertilization (IVF) success. The effect of varicocelectomy on IVF of human oocytes was examined on thirteen couples with normal female fertility, but severe oligozoospermia and the presence varicocele in the males with failure of fer...
متن کاملThe effect of glucocorticoids on mouse oocyte in vitro maturation and subsequent fertilization and embryo development.
Increased glucocorticoid levels, due to medical therapy or stress-related, may affect reproduction via the hypothalamus-pituitary-axis or directly at the oocyte level. We examined the effects of natural (corticosterone) or synthetic (dexamethasone) glucocorticoids on mouse oocyte maturation and underlying changes in extracellular signal-regulated kinase (ERK) phosphorylation patterns. Fertiliza...
متن کاملP-23: Effect of Melatonin on In vitro Maturation, Fertilization and Resulted Embryo Development in Mouse
Background: Melatonin has been recognised as effective reactive oxygen species (ROS) scavenger. antioxident melatonin effects has been expressed in management of cancer, alzheimer, diabet diseases. This study designed to determine the effect of melatonin on in vitro oocytes maturation and fertilization and cleavage and blastocyst development rate of mouse. Materials and Methods: Cumulus - oocyt...
متن کاملO-11: Diverse Effects of Polyunsaturated Fatty Acids on Oocyte Maturation and Development In vitro
Background: Polyunsaturated fatty acids (PUFAs) have been shown to influence fertility and endocrinology of reproduction and metabolic activity in many species. In dairy cows, we and others have shown changes in steroid and metabolic hormones and prostaglandins leading to alteration of ovarian activity and uterine function. These can influence fertility by changes in folliculogenesis cyclicity ...
