Causes of labial fusion

It's not certain what causes labial fusion, but it usually occurs as a result of some irritation or inflammation of the vaginal area, known as Vaginitis .

This can cause the inner lips of the vulva to become sticky. Without enough oestrogen in the body, which is quite normal before puberty ,the lips can stay stuck together and gradually become firmly joined.

The problem is rarely seen in girls after they begin puberty, because this is when they start to produce the hormone oestrogen.
