Labial Hypertrophy

Labial hypertrophy is a condition in which one or both sides of a girl’s labia (sometimes called the vaginal lips) are larger than normal.

The condition usually affects the inner labia but it can also affect the outer labia, the two large folds of fatty tissue covering the vagina.

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

Causes & Risk Factors

The condition occurs when the labia don't develop normally during puberty. The cause is not yet known.

Symptoms & Types

Common symptoms include:

  • Visibly larger labia
  • Irritation, discomfort or pain in the crotch area when wearing tight clothing such as bathing suits or tights
  • A “bulge” in a girl’s underwear or swimsuit
  • Chronic vaginal yeast infections
  • Discomfort during physical activities such as bike riding, running, or horseback riding
  • Discomfort during sexual intercourse 

Diagnosis & Tests

The condition may become obvious during childhood or puberty. Diagnosis is confirmed through a physical exam.

Treatment & Care

Treatment depends on the individual and their symptoms.  

Loose-fitting clothing and creams can help prevent irritation. 

If the condition causes extreme discomfort or distress, a surgical procedure known as a labioplasty is available to reduce the labia to a more normal size.
