Labial Hypoplasia | Overview


The labia are basically two fat pads to protect a woman's clitoris and vagina from trauma. Labial hypoplasia is a harmless condition in which one or both sides of the labia don't form normally during puberty. One side may be normal while the other side grows smaller or is absent.

  • The cause of labial hypoplasia is unclear.
  • Missing one or both sides of the labia or having labia of different sizes has no long-term medical complications.
  • Women with labial hypoplasia have normal sexual function because the clitoris, clitoral hood and vagina are normal.
