Abstract

The objective of this study was to investigate the impact of protocols with agonists and antagonists of gonadotropin-releasing hormone (GnRH) on the quality of obtained embryos and also to compare the efficacy of different methods of embryo cryopreservation — vitrification and slow freezing method. The results revealed, that vitrification method provides better embryo survival rate, higher clinical pregnancy rate. No significant differences between both protocols of controlled ovarian hyperstimulation (COH) were found in the number of embryos of top and good quality
