Hormone swings linked to suicide risk in women: new study
NCT ID NCT04112368
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether stabilizing hormones with estrogen patches and progesterone pills could reduce suicidal thoughts in women with recent suicidal ideation. 124 women participated, tracking their daily mood and suicide risk over a month. The goal was to understand how natural hormone cycles influence short-term suicide risk, not to provide a treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Estradiol transdermal patch and oral micronized progesterone
- What this could lead to
- If successful, this could point toward a treatment that prevents monthly worsening of suicide risk in women of reproductive age.
- What could go wrong
- This is a small, early-phase study focused on understanding biology, not testing a treatment. The results may not lead to a direct therapy, and the hormone interventions may have side effects.
