Freezing of ovaries preserve fertility better than eggs. Women who freezed their ovaries tissues can have babies easily in future.
Eggs freezing requires an IVF with hormone replacement therapy before conception can take place while ovarian freezing reverses menopause and increases the chance of natural pregnancy without any fertility treatment.
Ovarian tissue cryopreservation can be considered as a good option for fertility preservation for women who are not ready to have children now; busy with their career or undergoing cancer treatment and choose to have children at old age or after treatment.
