BACKGROUND An inverse relationship between oocyte efficiency and ovarian response was reported in conventional IVF. The purpose of this study was to report metaphase II (MII) oocyte efficiency according to oocyte yield in minimal/mild stimulation IVF (mIVF) and to assess whether oocyte yield affects live birth rate (LBR). METHODS Infertile women (n = 264) aged < 39 years old with normal ovari...

background: the purpose of present study was to evaluate the role of pre-ovulatory gnrh agonist therapy on ivf outcomes in gnrh antagonist cycles. methods: in this prospective study we recruited 100 infertile women undergoing ivf cycles with gnrh antagonists. the patients were assigned to two groups: group a (the study group, n=42) were assigned for receiving hcg+triptorelin for the final oocyt...

OBJECTIVES To investigate whether a lower than expected number of oocyte after ≥14 mm follicle aspiration during OPU has any effect on pregnancy outcomes Methods: This is a retrospective study done between 2010 and 2013 at the IVF Unit of the Zeynep Kamil Women and Children Diseases Education and Research Hospital, dealing with the medical records of infertile patients who underwent IVF cycle a...

a:4:{s:10:"Background";s:1707:"Early embryonic development in mammals begins in transcriptional silence with an oocyte-mediated transcriptional reprogramming of parental gametes occurs during a so called across-the-board process of “erase-and-rebuild”. In this process, the parental transcription programs are erased long before (maternal) or soon thereafter (paternal) fertilization to generate a...

the aim of this study was to determine the quality of cumulus-oocyte-complexes (cocs) and the effects of bovine serum albumin (bsa) supplementation on in vitro maturation and fertilization rate of buffalo oocytes. cocs were collected from slaughterhouse buffalo ovaries by aspiration method. only normal grades cocs were matured for 48 hours in tcm-199 media. two groups were created: one for the ...

Background: Intracytoplasmic sperm injection (ICSI) is the choice option for treatment of couples with severe male infertility. Recent studies indicate that the ICSI procedure or the technique itself cannot increase chromosomal abnormalities observed in born children. It maybe result of the Materialss used during ICSI procedure such as PVP and hyalorunidase. Activation of the oocytes might be c...
