The objective of this study was to evaluate the effects different maturation systems on oocyte resistance after vitrification and phospholipid profile plasma membrane (PM). Four were tested: 1) in vitro using immature oocytes aspirated from slaughterhouse ovaries (CONT; n = 136); 2) obtained by ovum pick-up (OPU) unstimulated heifers (IMA; 433); 3) OPU stimulated (FSH; 444); 4) vivo 24 hours prior an injection GnRH (MII; 658). A sample matured each fresh group analyzed matrix associated...
Embryo production by intrafollicular oocyte transfer (IFOT) represents an alternative for of a large number embryos without requiring any hormones and only basic laboratory handling. We aimed to (1) evaluate the efficiency IFOT using immature oocytes (IFIOT) (2) compare embryo development after IFIOT fresh or vitrified oocytes. First, six IFIOTs were performed obtained ovum pickup. After insemination uterine flush recovery, 21.3% total transferred structures recovered excluding recipient's...
The association of a technique that guarantees the embryo quality in vivo blastocyst and otherwise allows increment production, such as vitro model, would result healthier cheaper embryo. Immature oocytes intrafollicular transfer (IOIFT) is which immature obtained by ovum pickup are injected into dominant follicle synchronized recipient. We hypothesised IOIFT could support development even after oocyte vitrification. aimed to compare or traditional system using fresh vitrified oocytes....
