To improve outcome after ovarian tissue cryopreservation and transplantation: Clinical approach based on a case series and literature review

A passive ART approach is advised after OTT, except in patients with pre-existing fertility issues. For others, ART can be considered if pregnancy is not achieved within 10 months after ovarian function recovery. Repeated transplantation has limited efficacy and should be carefully considered, especially in those who did not regain ovarian function after first OTT.
