NCT ID NCT05479474
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Stanford study tests whether injecting a man's own platelet-rich plasma (PRP) into his testicles can help produce sperm. Ten men with nonobstructive azoospermia who previously failed sperm retrieval will receive the injection. Three months later, doctors will check for sperm and, if found, use it for IVF.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
platelet-rich plasma (PRP)
What this could lead to
If it works, this could offer a new option for men with no sperm in their ejaculate to father biological children using their own sperm.
What could go wrong
This is a very early, tiny trial with only 10 participants. The procedure is experimental, may not produce sperm, and carries risks from the injection and blood draw.
