NCT ID NCT06387498
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study looks at whether it's possible and safe to freeze testicular tissue for males of any age who face infertility due to medical treatments like chemotherapy or radiation. Researchers will collect a small sample of testicular tissue through a biopsy and freeze it for potential future use. The goal is to see how many eligible patients choose the procedure and how many have their tissue successfully preserved, while also tracking any side effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- testicular tissue biopsy and cryopreservation
- What this could lead to
- If successful, this could offer a way to preserve fertility for males who might otherwise become infertile due to medical treatments or conditions.
- What could go wrong
- This is an early feasibility study with only 60 participants. The procedure carries risks like bleeding, infection, or long-term pain, and it's not yet known if the frozen tissue can later restore fertility.
