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

Summary

This study tests whether a soft silicone ring, called an Arabin pessary, can help prevent preterm birth (before 37 weeks) in women carrying a single baby who have a short cervix. The trial involves 544 participants and compares those who receive the pessary to those who do not. The goal is to see if this simple device can reduce the risk of early delivery or fetal death.
