Could expressing milk before birth help preterm babies?
NCT ID NCT07191366
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at whether pregnant women at high risk of preterm birth can safely express breastmilk from week 28 to 34 of pregnancy. Researchers will check if it affects how soon the baby is born, how much milk is available at birth, and whether it helps with breastfeeding. The goal is to see if this simple technique can give preterm newborns better access to their mother's milk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Hand stimulation of the breast (antenatal breastmilk expression)
- What this could lead to
- If it works, this could give preterm babies earlier access to their mother's milk, potentially improving nutrition and breastfeeding success.
- What could go wrong
- This is an early-stage study with 250 participants, so results may not apply to all high-risk pregnancies. There is a small risk that expressing milk could trigger contractions or other complications.
