Cervical adoption, also known as cervical dilation, is the process of opening up the cervix by widening it. This can be done manually by a doctor or gynecologist, or it can occur naturally during labor and childbirth.
Dilation of the cervix is necessary for the baby to pass through the birth canal during delivery. Without cervical dilation, vaginal delivery is nearly impossible.
In rare cases, cervical dilation may also be necessary for certain medical procedures, such as a biopsy or hysteroscopy.
Understanding the Cervix
Before diving into cervical dilation, it’s important to understand the anatomy of the cervix. The cervix is the lower part of the uterus, which connects to the vagina.
It’s made up of firm and fibrous tissues, which help it stay closed during pregnancy to protect the developing fetus. The cervix also plays a role in keeping unwanted bacteria out and holding the fetus in until it’s time for delivery.
During pregnancy, the cervix naturally softens and stretches in preparation for childbirth. This is known as effacement.
Effacement is measured in percentages, with 0% indicating that the cervix is long and thick, and 100% indicating that the cervix is thin and stretched. Typically, the cervix will efface before it dilates.
Cervical Dilation During Labor
During labor, the cervical dilation process is triggered by several hormones in the body, including oxytocin, prostaglandins, and estrogen.
These hormones work together to soften and open up the cervix, making way for the baby to move through the birth canal. Dilation may start slowly, progressing by only a few millimeters per hour, or it may happen more rapidly, especially during the latter stages of labor.
Cervical dilation may be monitored by a healthcare provider during labor using a pelvic exam. During a pelvic exam, the provider will insert gloved fingers into the vagina and assess the position and thickness of the cervix.

They will then determine how many centimeters the cervix has dilated by measuring the opening with their fingers. The measurement is typically expressed in centimeters and can be anywhere from 0 (closed cervix) to 10 (fully opened cervix), depending on the stage of labor.
Medical Procedures That Require Cervical Dilation
While cervical dilation during labor is a natural process, there are some medical procedures that may require manual dilation of the cervix. These procedures are usually done for diagnostic or therapeutic purposes, such as:.
- Biopsy: A small sample of tissue is removed from the cervix for examination and diagnosis of abnormal cells.
- Hysteroscopy: A thin, lighted tube is inserted into the cervix to examine the uterus and cervix for abnormalities.
- IUD insertion: A contraceptive device is inserted into the cervix and uterus for long-term birth control.
- Cervical cerclage: A stitch is placed around the cervix to help prevent preterm labor or premature delivery.
These procedures may be performed under local anesthesia. However, some women may require conscious sedation or even general anesthesia to help them relax and reduce pain during the procedure.
When is Cervical Dilation Needed?
Cervical dilation is a necessary part of the labor and delivery process. Without it, vaginal delivery is impossible. However, not all women will experience cervical dilation at the same rate or in the same way.
In some cases, cervical dilation may occur too slowly or not at all. This is known as cervical dystocia. Cervical dystocia may occur due to several factors, including:.
- Abnormal fetal position
- Large fetal size
- Scar tissue or adhesions from previous procedures
- Infection or inflammation of the cervix
In cases of cervical dystocia, medical intervention may be necessary to help speed up the dilation process. This may include the administration of medications, such as oxytocin, or manual dilation of the cervix by a healthcare provider.
In severe cases, a C-section delivery may be necessary.
The Bottom Line
Cervical adoption or cervical dilation is an essential part of the labor and delivery process. However, it is important to note that not all women will dilate at the same rate or in the same way.
In some cases, medical intervention may be necessary to help speed up the dilation process if it’s too slow or not happening at all.
As with any medical procedure, it’s important to speak with your healthcare provider to understand the risks and benefits of cervical dilation and any related procedures that may be required.
