NCT ID NCT07062237

First seen Jun 27, 2026 · Last updated Jul 10, 2026 · Updated 2 times

Summary

This study compares two sperm collection timings—1 hour versus the usual 2-5 days of abstinence—to see which leads to more embryos with normal chromosomes during IVF. Researchers will track embryo health and pregnancy rates in 187 women. The goal is to find a simple way to improve IVF outcomes without extra drugs or procedures.

What this could mean

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

Active substance
ultrashort abstinence (1 hour) vs standard abstinence (2-5 days) for sperm collection
What this could lead to
If it works, this could point toward a simple way to increase the number of healthy embryos in IVF, potentially improving pregnancy success rates.
What could go wrong
This is an early-stage study with 187 participants, so results may not apply to everyone. The shorter abstinence might reduce sperm count or quality, and the benefit for pregnancy rates is not yet proven.
