Embryonic egg freezing - Vitrification or Slow-freeze?

Abstract

In Vitro Fertilization (IVF) is a form of assisted reproductive technology (ART) that combines an egg from the women and a sperm sample from the man in a dish within the laboratory setting. The embryo that develops and divides is then transferred into the uterus of the woman for attachment and growth. The woman can also freeze more of her eggs, so that if the fresh transfer does not take, she has the option of trying again with her frozen eggs. Therefore, the cryopreservation of the eggs is an important and necessary component of the fertilization process, and this study evaluated the success rate, and the morphology of two different types: vitrification and slow freezing.
