New study offers hope for girls facing infertility from medical treatments
NCT ID NCT06710769
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study offers girls facing fertility-threatening medical treatments the option to freeze their ovarian tissue for future use. Up to 40 participants will have a small piece of ovary removed laparoscopically and stored. The goal is to see how many choose this option and at what age they later use the tissue.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ovarian tissue freezing procedure
- What this could lead to
- If successful, this could help girls preserve their ability to have biological children after treatments that might otherwise cause infertility.
- What could go wrong
- This is a small, early-stage study focused on feasibility, not on actual pregnancy outcomes. The tissue may not restore fertility when used later, and the procedure carries surgical risks.
