NCT ID NCT07532629
First seen Apr 19, 2026 · Last updated Jun 20, 2026 · Updated 7 times
Summary
This study looks at how the natural microbes and chemical profiles in couples' bodies relate to IVF outcomes. Researchers will collect samples from 1000 couples and track whether they have a baby, miscarriage, or other pregnancy results. The goal is to find patterns that might help predict success, but this is an observation-only study with no treatment given.
