Where we are at with ovarian tissue freezing

Nearly four out of 10 women who undergo ovarian tissue cryopreservation are able to have children, according to the latest evidence.

The results from a 17-year study of cancer patients suggest it can now be considered a viable option for fertility preservation.

In fact, the authors argue the procedure is superior to egg freezing in that it can also reverse menopause and restore natural fertility.

They say the next frontier is to explore its potential in delaying childbearing among healthy women.

“Ovarian tissue cryopreservation (OTC) enables preservation of a potentially large number of primordial follicles, bringing the possibility of not only restoring spontaneous fertility but also the endocrine function upon transplantation,” the US authors explain in the journal Reproductive Sciences.

“It does not require ovarian stimulation, avoiding significant delays in the initiation of cancer treatments, and can be utilised in prepubertal children.”

In this study, 19 reports were included for qualitative synthesis.

The researchers found that:
