The egg and the cumulus are referred to as the oocyte-cumulus complex. Pubmed and medline were searched up to April for papers on oocyte fertilization and its mechanistic components. In vitro maturation is an assistive reproductive technique ART typically used in patients with fertility issues including polycystic ovary syndrome PCOS , high antral follicle counts and ovarian hyper-responsiveness. Retrieved on April 24, A few live births have already been made by taking small early tertiary follicles, letting them mature in vitro and subsequently fertilizing them. It can be offered to women with infertility problems, combined with IVF, offering women pregnancy without ovarian stimulation. Realizing this fundamental difference, vitrification concept has been developed and successfully applied in IVF treatment with the first life birth following vitrification of oocytes achieved in

Importantly, markers of successful cytoplasmic maturation are also not readily visualized, thus making judgment of oocyte quality difficult. Some of the discrepancy seen in the literature could be the result of inexact timing of PN observation; if a laboratory is not consistent, PN patterns may be visible but change over time and depending on the PN check relative to fertilization, could result in discrepant PN scoring. The development of the trophectoderm and the inner cell mass is equally important for a healthy pregnancy to develop. Slow freezing traditionally has been the most commonly used method to cryopreserve oocytes, and is the method that has resulted in the most babies born from frozen oocytes worldwide.
