Zusammenfassung
Vor nunmehr über 30 Jahren wurde die Kryokonservierung in die Reproduktionsmedizin eingeführt und seitdem kontinuierlich weiterentwickelt. Die Vitrifikation, das ultraschnelle Einfrieren menschlicher Eizellen, Zygoten und Embryonen, wird dabei immer häufiger eingesetzt. In diesem Beitrag wird das Cryotop-Verfahren zur Vitrifikation beschrieben. Es werden aktuelle Ergebnisse, Fertilisations- und Schwangerschaftsraten, präsentiert, die nach Vitrifikation von Eizellen und Embryonen in verschiedenen Entwicklungsstadien erzielt wurden.
Abstract
Over 30 years ago, the cryoconservation procedure was introduced into assisted reproduction technology and has since been continuously improved. Vitrification, the ultra-rapid freezing of human oocytes, zygotes and embryos, is becoming more and more the method of choice. This paper presents the latest results, fertilization and pregnancy rates, after vitrification of different developmental stages using the cryotop method.
