What does the current literature say about outcomes of female fertility cryopreservation in children with cancer? I'm Alex Halpern, a research fellow from Children's National, and this is an article that you should know. Gillippelli et al. performed a systematic retrospective review trying to answer this question. They initially reviewed 104 abstracts and 34 full text articles and ended up including 12 studies in their review. They found that ovarian tissue cryopreservation was performed in 501 patients, with 5.9% of these patients undergoing ovarian tissue transplantation. After ovarian tissue transplantation, 33% of these patients were able to become pregnant. So, it seems like ovarian tissue cryopreservation has great advantages for pediatric cancer patients, but needs to be studied further. Does this information change your practice at all?
