Vitrification of human germinal vesicle oocytes; before or after in vitro maturation?
Background The utilization of immature oocytes derived from stimulated cycles could be of great importance, specially for urgent fertility preservation cases. The aim of the current study was to determine whether in-vitro maturation is more successful before or after the vitrification of these oocytes. MaterialsAndMethods The study was performed in a private IVF center. 318 germinal vesicle (GV...
متن کاملthe effects of cumulus cells on in vitro maturation of mouse germinal vesicle stage oocytes
background: in vitro maturation (ivm) of oocytes is a promising technique to reduce the costs and avert the side-effects of gonadotropin stimulation for in vitro fertilization (ivf). the pregnancy rates from oocytes matured in vitro are much lower than those of in vivo stimulation cycles, indicating that optimization of ivm remains a challenge. objective: in this study, we investigated the effe...

متن کاملP-72: Ovine Oocytes Vitrified at Germinal Vesicle Stage as Cytoplast Recipients forSomatic Cell Nuclear Transfer (SCNT)
Background: The cryopreservation of immature oocytes at the germinal vesicle (GV) stage would create an easily accessible, nonseasonal source of female gametes for research and reproduction. The present study investigated the ability of ovine oocytes vitrified at the GV stage using a cryoloop to be subsequently matured, fertilized and cultured in vitro to blastocyst-stage embryos. Materials and...
متن کاملProduction of blastocysts following in vitro maturation and fertilization of dromedary camel oocytes vitrified at the germinal vesicle stage
Cryopreservation of oocytes would serve as an alternative to overcome the limited availability of dromedary camel oocytes and facilitate improvements in IVP techniques in this species. Our goal was to develop a protocol for the vitrification of camel oocytes at the germinal vesicle (GV) stage using different cryoprotectant combinations: 20% EG and 20% DMSO (VS1), 25% EG plus 25% DMSO (VS2) or 2...
