Blood test on IUI day may reveal pregnancy clues
NCT ID NCT07038616
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 158 women having intrauterine insemination (IUI) to see if progesterone levels on the day of insemination are linked to pregnancy rates. IUI is a simpler, cheaper fertility treatment than IVF, but success rates are low. Researchers measured progesterone and other hormones in routine blood tests. The goal is to find a way to better time insemination and improve outcomes.
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 a link is found, this could help doctors time insemination better and improve IUI success rates without extra drugs.
- What could go wrong
- This is a small, completed observational study, not a treatment trial. It only looks for a correlation, so it won't prove what works best.
