Can freezing ovarian tissue help girls have babies later?
NCT ID NCT02646384
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study offers girls from birth to age 17 the chance to freeze their ovarian tissue before medical treatments that could harm their fertility, such as chemotherapy or radiation. The tissue is removed surgically and stored. Later, if they want to have children, the tissue can be transplanted back. The study is tracking how many pregnancies and live births result from this approach.
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 cryopreservation (freezing and storage of ovarian tissue)
What this could lead to
If successful, this could help girls who need cancer treatment or other therapies to have a chance at biological children later in life.
What could go wrong
This is an early-stage experimental procedure, and it is not yet proven how often it leads to pregnancy. The tissue may not survive transplantation, and risks from surgery exist.
