Abstract
Retrospective analysis at Kyono ART Clinic Comparison of embryological development pregnancy live birth and fetal malformation between oocytes with SERC the SERC+ group and those without the SERC− group in 2158 patients 3758 cycles after ICSIFertilization and implantation rate were significantly lower in SERC+ MII oocytes than in SERC− MII oocytes After the transfer of fresh and vitrified embryos derived from SERC+ oocytes 14 pregnancies resulted in 14 healthy babies including 2 from fresh embryo transfer ET and 12 from vitrifiedwarmed ET with no malformationsThe presence of SERC in MII oocytes was associated with significantly lower fertilization rates and implantation rates than seen in SERC− MII oocytes within SERC + cycles However SERC had no impact on postimplantation development as well as neonatal outcome
