Abstract

The cryopreservation of ovarian tissue with subsequent transplantation of the tissue represents an established method of fertility protection for female patients who have to undergo gonadotoxic therapy. The procedure can be performed at any point in the cycle and thus generally does not lead to any delay in oncological therapy. With the aid of this procedure, more than 130 births to date worldwide have been able to be recorded. The birth rate is currently approximately 30% and it can be assumed that this will increase through the further optimisation of the cryopreservation and surgical technique. The concept paper presented here is intended to provide guidance for managing cryopreservation and transplantation of ovarian tissue to German-speaking reproductive medicine centres.

Die Kryokonservierung von Ovarialgewebe mit anschließender Transplantation des Gewebes stellt eine etablierte Methode der Fertilitätsprotektion für Patientinnen dar, die sich einer gonadotoxischen Therapie unterziehen müssen. Das Verfahren kann zu jedem Zykluszeitpunkt erfolgen und führt somit meistens zu keiner Verzögerung der onkologischen Therapie. Mithilfe dieses Verfahrens konnten bis dato mehr als 130 Geburten weltweit verzeichnet werden. Die Geburtenrate beträgt derzeit ca. 30% und es ist von einer Steigerung durch eine weitere Optimierung der Kryokonservierungs- und Operationstechnik auszugehen. Das hier vorgelegte Konzeptpapier soll Handlungsempfehlungen für den Umgang mit der Kryokonservierung und Transplantation von Ovarialgewebe an deutschsprachigen reproduktionsmedizinischen Zentren geben.

Keywords: Ferti PROTEKT; cryopreservation; fertility protection; ovarian tissue; transplantation.
