Cervical Hypoplasia


Cervical hypoplasia is when a girl is born with a cervix that is smaller than normal. The cervix is the lower part of the uterus, sometimes called the “neck,” that connects the uterus to the vagina. 

Patients can be seen by Texas Children's experts in Pediatric and Adolescent Gynecology.

Causes & Risk Factors

Cervical hypoplasia is rare a congenital disorder, meaning it is present at birth. It occurs when the reproductive organs don’t develop properly in the fetus. Frequently this condition is associated with abnormal or absent vaginal development.

The cause of this abnormal fetal development is not yet known. 

Symptoms & Types

Symptoms may include:

  • No monthly periods (amenorrhea)
  • Abdominal pain – caused by blood collecting in the uterus

Diagnosis & Tests

A smaller than normal cervix may be discovered during a pelvic exam, which may prompt additional testing including:

  • Blood tests
  • Ultrasound – to obtain images of the reproductive organs
  • Magnetic resonance imaging (MRI)for more detailed images of the reproductive tract

Treatment & Care

Treatment depends on the individual condition and their symptoms.
