O-24: Increased Homocysteinein PCOS Affects Oocyte and Embryo Quality
Background: The biochemical characteristics of the follicular fluid (FF) play essential role in oocyte quality, the subsequent fertilization potential and embryo development. The oocyte quality and metabolism largely depends on follicular microenvironment. Present study aimed to investigate the relationship between oocyte quality and FF homocysteine (Hcy) level in women undergoing to IVF treatm...
متن کاملGonadotropin Stimulation Regimens and Oocyte Embryo Quality
In the normal human menstrual cycle, the final phase of ovarian folliculogenesis leading upto the pre-ovulatory stage is gonadotropin dependent. Luteinising hormone (LH) acts synergistically with follicle stimulating hormone (FSH) to achieve follicular steroidogenesis, luteinisation and ovulation. It therefore follows that the maturational process of the oocyte contained within the follicle and...
متن کاملOocyte morphology does not affect fertilization rate, embryo quality and implantation rate after intracytoplasmic sperm injection.
In this study, we compared the fertilization rate and embryo quality after intracytoplasmic sperm injection (ICSI) as they relate to oocyte morphology. A total of 654 ICSI cycles yielding 5903 metaphase II oocytes were observed. The oocytes retrieved in these cycles were divided into (i) normal oocytes, (ii) oocytes with extracytoplasmic abnormalities (dark zona pellucida and large perivitellin...
متن کاملOocyte developmental competence and embryo quality: distinction and new perspectives
In vitro embryo production is the cornerstone of infertility treatment in human and is increasingly used in cattle to propagate high genetic merit animals. To increase its efficiency, many different approaches have been tested all of which stem from the concepts of oocyte quality and developmental competence. Presented here are recently reported findings and perspectives related to bovine oocyt...
متن کاملO-10: Assessment of Oocyte and Embryo Quality in Different Time between Oocyte Retrieval and hCG Priming
Background: Abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. In this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hCG) administration. Materials and Methods: A total of 985 metaphase II were ...
