Frozen testicle tissue may help infertile men have kids
NCT ID NCT07364409
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This experimental study tests whether frozen-thawed testis tissue, when grafted under the skin, can produce sperm in men with infertility. Five men will receive their own stored tissue. The goal is to see if viable sperm can be retrieved, potentially offering a future fertility option for cancer survivors.
