First seen Apr 03, 2026 · Last updated Apr 30, 2026 · Updated 5 times
Summary
This study tested two methods—natural progesterone and a vaginal pessary—to see which better prevents early birth in pregnant women with a short cervix (25 mm or less). 203 women with a single baby between 20-24 weeks of pregnancy took part. The goal was to reduce births before 34 weeks. Results help doctors choose the best option for at-risk pregnancies.
