Oocyte Cryopreservation
It is is useful to preserve fertility in women not prepared to have a family and, for the first time in human history, the biological clock can be stopped.
It gives opportunity to women undergoing cancer treatment to preserve fertility.
It also would benefit the younger woman who doesn’t anticipate motherhood in the near future and wants to preserve her fertility. Finally, couples undergoing IVF could freeze extra eggs instead of embryos. Once the couple decides that their family is complete, it is much easier emotionally to discard frozen eggs instead of frozen embryos.
