Cervix Disorders

A cervix disorder is a problem with your cervix. The cervix is part of the female reproductive system. It is the lower, narrow end of the uterus (womb), which opens into the vagina (birth canal). The cervix has a small opening that expands during childbirth. It also allows menstrual blood to leave your body.
