Oocytes Freezing in Patient with Cancer
Ovarian tissue cryopreservation was first performed more than 20 years ago. The first live birth after ovarian tissue transplantation after cryopreservation was reported in 2004  followed by a second one the following year . Today, with more than 120 live births and a 30% success rate, this technique is no longer considered experimental. However, the evolution of oocyte and embryo vitrification techniques has limited the ovarian cryopreservation to a selected number of patients. The ASRM (American Society for Reproductive Medicine) recognizes the cryopreservation of oocytes and embryos as only valid methods for the preservation of fertility.
