Vitrification is a method of cryopreservation which leads to a glass-like amorphous solidification of the cell. Due to its easy handling concerning cost-effectiveness and cell survival, it has become well established in modern assisted reproduction techniques. Multiple studies have demonstrated reproducible cell survival rates after thawing. According to the German IVF survey pregnancy rates now reach nearly 20%. The indications for vitrification vary from classical cold storage of supernumerary zygotes to cryopreservation of oocytes or ovarian tissue for fertility preservation strategies in young women. Until now, follow-up studies concerning fetal health after cryopreservation have not been available in sufficient number and results are still awaited.
