“…On apportera ici une solution au don. Il faut se rappeler que la loi européenne demande aux pays membres d'assurer les besoins de santé de leur population, il est intéressant de souligner que dans ce cadre, la France ne répond pas à la demande actuelle et se doit de contribuer financièrement à la prise en charge à l'extérieur des frontières (Boyer, 2010).…”

Ovocyte vitrification was finally authorized by the new law voted in July 2011 upon the revision of the French bioethics law. Expected for 30 years, cryopreservation of female gametes had a major impact on Assisted Reproductive Technologies (ART) practice worldwide and in our country. It brought tremendous changes in the field of reproductive biology, from intraconjugal infertility management to gamete donation, through autologous cryopreservation for fertility preservation. Although it appears to be "obvious", ovocyte vitrification seems to be barely used as a routine technique in French IVF laboratories. We will discuss the events that led to the present situation. We will also tackle the expected benefits of ovocyte vitrification especially as an alternative to embryo freezing.

“…Aprè s 30 ans d'Assistance mé dicale à la procré ation (AMP) sans congé lation d'ovocyte en routine, le 7 juillet 2011 la loi reconnaît la conservation ovocytaire grâce à la maîtrise technique de la vitrification [1][2][3]. L'objectif affiché est de limiter le nombre d'embryons congelé s exclus du projet parental.…”

Purpose Oocyte vitrification is a worldwide used technique that has proved its worth. Although it was shown not to alter oocyte integrity, a recent study concluded that it may affect oocyte embryo development. As the morphology and kinetics of embryos derived from sibling fresh and vitrified oocytes have not been described previously, the present study evaluates cleavage rate, blastomeres size, fragmentation rate, and blastocyst formation in vitrified/warmed oocyte derived embryos (VODE) as compared with sibling fresh oocytes derived embryos (FODE). Methods This investigation included 90 infertility cases displaying large cohort of mature oocytes at pick up, divided into 2 groups after denudation. A part of oocytes underwent ICSI while others were vitrified. Oocyte warming cycles were performed when no pregnancy was achieved using fresh eggs. Zygote to blastocyst development was recorded prospectively in an image database up to day 5. Results VODE did not show major difference as compared with FODE in terms of cleavage rate, number of blastomeres, fragmentation rate, and blastomeres size. Furthermore, percentage of morulae at day 4 and blastocysts at day 5 are not affected by oocyte vitrification. Conclusion Although our results show that embryo development is not altered by oocyte vitrification, offspring follow-up is essential to exclude any adverse developmental effect of the technique.
