For women who do not have a birth plan or do not have fertility conditions, egg freezing is a better way to preserve fertility.

Frozen eggs refer to mature oocytes (commonly known as eggs) obtained by puncturing ovaries through medical technology. The mature oocytes are frozen and stored in ultra-low temperature environment (liquid nitrogen,-196 ℃) for a long time with the help of professional cryopreservation technology. Thawing and resuscitating frozen oocytes when necessary can be used to solve fertility problems in in vitro fertilization and embryo transfer technology.

Egg freezing is one of the important derivative techniques of in vitro fertilization and embryo transfer, which is mainly used for long-term preservation of mature oocytes of women in vitro, and provides the possibility of fertility for women with medical indications for thawing and resuscitation to obtain viable oocytes.
