Normal maternal cervical length

Normal cervical length is analyzed on a case-by-case basis.

Maternal cervical length is an important indicator of pregnancy stability and risk of premature delivery. In general, the normal cervical length for non-pregnant women is between 2.5 and 3 cm. This length is effective in maintaining pregnancy stability and reducing the risk of miscarriage and premature delivery.

During pregnancy, especially in the second trimester, the normal value of cervical length varies, usually 3.6±0.5 cm. Monitoring cervical length during this period is especially important to prevent premature birth. If the cervical length is less than 2.5 cm, accompanied by abdominal pain, bleeding and other symptoms, it is necessary to be alert to the increased risk of miscarriage or premature birth.

Changes in cervical length may be affected by a variety of factors, including age, birth history, history of cervical surgery, etc. Therefore, women with abnormal cervical length, especially those planning pregnancy, should be evaluated and treated under the guidance of professional doctors. If necessary, cervical cerclage and other interventions can be taken to ensure maternal and infant safety.
