NCT ID NCT07268235

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at 129 men with low or no sperm in their semen who had sperm surgically removed from the testicle (micro-TESE) for IVF. Researchers compared doing the sperm retrieval 24 hours versus 48 hours before the egg retrieval to see if timing affected live birth rates. The goal is to find the best schedule for couples undergoing fertility treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to

If timing matters, it could help doctors plan IVF procedures to improve chances of live birth for couples with male infertility.

What could go wrong

This is a small, retrospective study (129 participants) from a single clinic, so results may not apply to everyone. It only looks at timing, not a new treatment.
