First seen Nov 01, 2025 · Last updated May 10, 2026 · Updated 28 times
Summary
This study tests whether taking clomiphene citrate (a fertility drug) for 9 months can help men with non-obstructive azoospermia (no sperm in semen due to testicular failure) produce sperm for IVF. About 128 men who had a failed first sperm retrieval surgery will receive either the drug or a placebo. The goal is to see if more men can have sperm found in their semen or during a second surgery, offering a chance at biological fatherhood.
