Incomplete denudation of oocytes prior to ICSI enhances embryo quality and blastocyst development.
BACKGROUND Granulosa cells are essential mediators of oocyte maturation and fertilization. Because of the denudation of oocytes in preparation for ICSI, any potential positive effect of surplus cumulus cells (CCs) on further development would be unable to exert further effect. In order to evaluate the actual influence of adhering cumulus cells on further preimplantation development, this prospe...
متن کاملpreimplantation mouse embryo
The role of membrane sterols in the compaction and subsequent development of the preimplantation mouse embryo was studied by incubating embryos in 7-ketocholesterol and other oxygenated sterols. These sterols have been shown to inhibit sterol synthesis and deplete membranes of cholesterol in a variety of other cell types. Compaction and subsequent blastocyst formation were normal when embryos w...
متن کاملLow concentration of hyaluronidase for oocyte denudation can improve fertilization rates and embryo quality
OBJECTIVE Hyaluronidase enzyme is an extremely important factor for the process of oocyte denudation, but little is known about its negative effects. METHODS This prospective randomized study analyzed the results of using different concentrations of hyaluronidase (Diluted: 8IU/mL and Normal: 80IU/mL) used for denudation of sibling-oocytes for 22 women undergoing treatment for assisted reprodu...

متن کاملGlycine increases preimplantation development of mouse oocytes following vitrification at the germinal vesicle stage
Ice-free cryopreservation, referred to as vitrification, is receiving increased attention in the human and animal assisted reproduction. However, it introduces the detrimental osmotic stress by adding and removing high contents of cryoprotectants. In this study, we evaluated the effects of normalizing cell volume regulation by adding glycine, an organic osmolyte, during vitrification of mouse g...
