• Collecting and freezing ovarian tissue when young, then transplanting it back years later, is being proposed as a way to restore hormone production and put the onset of menopause on hold, potentially for many years.
• A modeling study in the American Journal of Obstetrics and Gynecology (Oktay, Yale) estimates that reimplanting bits of one's own frozen ovaries every few years could maintain cyclical hormonal fluctuations and potentially delay menopause for several decades if started before age 40.
• Beyond age 40, the procedure is unlikely to prevent the onset of menopause, per Oktay's research.
• Outside experts have raised concerns about using the technique to delay menopause in healthy individuals, say the potential to reduce health-condition risk is oversold, and note that existing treatments for menopause symptoms are simpler and safer than an elective procedure requiring surgery in one's 20s or 30s, decades of tissue storage, and multiple implant surgeries.
• About 20 carefully screened individuals have stored ovarian tissue at Oktay's clinic in anticipation of potentially delaying menopause, qualifying for health reasons such as a family history of early menopause and high risk for menopause-related illness.
• The technique is an established fertility-preservation option for young people about to undergo chemotherapy, with more than 200 babies born using it and roughly a 28 percent live-birth success rate in a recent review.
