Approach to fertility preservation for patients undergoing gonadotoxic therapy^*

¶ Ovarian tissue can be cryopreserved for potential future procedures such as in vitro follicle growth or tumor cell purging.

◊ When appropriate, ovarian tissue cryopreservation can be combined with oocyte or embryo cryopreservation to increase treatment success.
