abstract：:Oocyte vitrification has been introduced into clinical settings without extensive pre-clinical safety testing. In this study, we analysed major safety aspects of human oocyte vitrification in a high security closed system: (i) chromosomal meiotic segregation, (ii) embryonic developmental kinetics and (iii) DNA (hydrox...
