Why Cervical Length Matters During Pregnancy: Understanding the Risk of Preterm Birth

Cervical length is an important part of pregnancy monitoring, especially during the second trimester. The cervix normally remains long and closed during pregnancy, but in some women it may begin to shorten earlier than expected.

A shorter cervix can sometimes be associated with an increased risk of preterm birth. Doctors may recommend a transvaginal ultrasound to measure cervical length in women with certain risk factors or pregnancy histories.

Depending on the findings, further monitoring or treatment may be advised. Regular antenatal visits and timely assessment can help doctors identify changes early and plan appropriate pregnancy care for both mother and baby.
