Abstract
|
|
|
Background: In recent years, the demand for fertility preservation for both oncologic and nononcologic reasons, as well as for personal reasons, has increased dramatically.
Current Concepts: Currently, embryo and oocyte cryopreservation after ovarian stimulation are the mainstays of fertility preservation treatment in women. Embryo cryopreservation is an established and the most successful method of fertility preservation when sufficient time (approximately 2 weeks) is available to perform ovarian stimulation. Recent advances in freezing techniques (vitrification) have significantly improved the outcomes from oocyte cryopreservation that are comparable with those from embryo cryopreservation.
Discussion and Conclusion: This review focuses on the indications for the two techniques of fertility preservation and their results. For women to receive timely opportunities to preserve fertility, it is necessary to raise awareness among all medical departments and the public.
