Elevated Progesterone Levels on the Day of Oocyte Maturation May Affect Top Quality Embryo IVF Cycles
In contrast to the impact of elevated progesterone on endometrial receptivity, the data on whether increased progesterone levels affects the quality of embryos is still limited. This study retrospectively enrolled 4,236 fresh in vitro fertilization (IVF) cycles and sought to determine whether increased progesterone is associated with adverse outcomes with regard to top quality embryos (TQE). Th...
متن کاملA cost-effectiveness comparison of embryo donation with oocyte donation.
OBJECTIVE To compare the cost-effectiveness of embryo donation (ED) to that of oocyte donation (OD). DESIGN Calculation of cost-effectiveness ratios (costs per outcome achieved) using data derived from clinical practices. SETTING In vitro fertilization centers and embryo donation programs. PATIENT(S) Infertile couples undergoing oocyte donation or embryo donation. INTERVENTION(S) Oocyte...
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 کاملO-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 کاملThe window for embryo transfer in oocyte donation cycles depends on the duration of progesterone therapy.
In 192 oocyte donation cycles performed between January 1993 and July 1996, we examined the width of 'the window for embryo transfer' using standard hormonal replacement methods. All transfers were performed within 48 h of insemination. We varied the day of embryo transfer with regard to the initiation of progesterone therapy and, thus, the duration of endometrial exposure to progesterone and a...
