Dear Dr. Vanessa,
I’m 24, and have not yet had any children. At my last gynecological exam, the clinician remarked that I have “the tiiiiiniest cervix!” I didn’t ask anything about it at the time, but now I’m wondering, is this something I should be concerned about? Will I have a difficult time giving birth?

Dear T.D.,
Please don’t let this clinician’s remark bother you. The remark may be more a reflection of the inexperience of the clinician than the size of your cervix. Regardless, having a small cervix does not mean that you will have a difficult time giving birth. You do not need any special evaluation or procedure because of this “lame” comment. Cervical size varies, but one thing is for sure, your cervix is small because you have not had any vaginal deliveries.
The cervix is the narrow, lower part — neck — of the uterus, with a narrow opening connecting the uterus to the vagina. A woman’s menstrual flow leaves the uterus through the opening of the cervix, which is called the os. Optimally, a pregnant woman’s cervix is long, thick, and firm so that it can provide support to keep the pregnancy within the uterus as well as to stretch open wide enough to facilitate childbirth. During pregnancy, the os is also plugged with cervical mucus to protect the pregnancy. Read the rest of this entry »
