How long is the normal cervical length?

The normal cervical length is 25 to 30 mm.

Although 25 to 30 mm is considered normal, there may actually be some variation between individuals. This is related to a variety of genetic, developmental and other factors. Monitoring cervical length is especially important during pregnancy. If the cervix is too short, it may increase the risk of premature birth. Cervical length can be assessed by ultrasound and other means in order to take timely intervention measures.

Accurate measurement of cervical length requires professional medical equipment and technology. Ultrasound is a commonly used test method, but the accuracy of the operation can be affected by many factors, such as the experience of the operator and the accuracy of the instrument.

Too short may be associated with congenital abnormalities, a history of cervical surgery, multiple births, etc., and may lead to a range of gynecological problems or adverse pregnancy outcomes. Too long may affect the delivery process to some extent.

For women, regular gynecological examinations, including evaluation of cervical length, can help identify potential problems early. This is important for maintaining female reproductive health.

Understanding normal cervical length and its related knowledge is essential for women's reproductive health management and pregnancy care.
