The aim of this review is to present information related to oocyte cryopreservation, and particularly oocyte vitrification, performed to preserve fertility in
oncologic and social indications. The success rates of oocyte cryopreservation have increased with the widespread use of the vitrification technique and are
currently similar to those of in vitro fertilization performed with fresh oocytes. Vitrification is the most successful technique for oocyte cryopreservation.
The most important factors that influence the success rate are the patient’s age at the time of vitrification and the number of mature oocytes frozen. Thus,
live birth rates differ for each age depending on the number of oocytes thawed and the freezing method. The American Society of Reproductive Medicine
and the American Society of Clinical Oncology recommend presenting the option of oocyte cryopreservation for fertility preservation in cancer patients.
Besides cancer patients, use of oocyte vitrification is increasing in women who wish to postpone pregnancy age and to have reproductive freedom with the
development of the cryopreservation technique and the achievement of pregnancy rates similar to the use of fresh oocytes. Patients are provided consultancy
service in terms of indication, the success rates by age, and the total number of oocytes frozen. It should be emphasized that this procedure is not a type of
insurance policy for fertility, especially in elective oocyte cryopreservation
