[Oocyte vitrification in an ART laboratory]

Abstract

Oocyte vitrification has been authorized in France after the modification of French bioethics law in July 2011. This evolution will bring a dramatic change in patients' management since, from 2011, infertile couples, oocyte donation and fertility preservation programs will benefit this technique in France. We have introduced oocyte vitrification in our ART laboratory through a validation of the method using Evidence-Based Medicine model: open system Cryotop, Ethylène-glycol 15% and DMSO 15%. Based on our 1-year experience, oocyte vitrification upgrades our daily practice while also minimizing embryo cryoconservation as recommended by the law.
