Brain blood flow differs between sexes – new study explores why

NCT ID NCT04265053

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This completed early-phase study looked at how sex and stress influence blood flow in the brain. Researchers gave 42 healthy young adults indomethacin (an anti-inflammatory drug) or a placebo to test whether a specific mechanism (COX signaling) explains differences between men and women. The goal is to gather knowledge that could lead to better, sex-specific treatments for brain blood vessel diseases.

What this could mean

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

Active substance
Indomethacin
What this could lead to
If successful, this could point toward sex-specific therapies for cerebrovascular diseases like stroke.
What could go wrong
This is a very early, small study in healthy young adults, so findings may not apply to older or sick populations. The drug used (indomethacin) is not being tested as a treatment here.
