Frozen testicle tissue may help cancer survivors become dads
NCT ID NCT07542626
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether transplanting a man's own frozen testicular tissue, stored before childhood cancer treatment, can restore fertility. Twenty men with azoospermia (no sperm) who want children will undergo the procedure. Doctors will check if the graft produces sperm and if that sperm can be used for in vitro fertilization.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
autologous transplantation of cryopreserved immature testicular tissue
What this could lead to
If successful, this could offer a way for men who became infertile after childhood cancer treatment to have biological children using their own frozen tissue.
What could go wrong
This is a very early pilot study with only 20 participants, so results may not apply widely. The graft may not produce viable sperm, and there is a risk of reintroducing cancer cells from the stored tissue.
