The primary contributing factor to<unk>  is low estrogen levels. A vulva with low estrogen exposure, such as that of a preadolescent, has delicate epithelial lining and is therefore vulnerable to irritation. Conditions causing irritation, such as infection, inflammation and trauma, cause the edges of the<unk> minora to fuse together. The<unk>  typically begins at the posterior frenulum of the<unk> minora and continues anteriorly. Most<unk>  adhesions resolve spontaneously before puberty as estrogen levels increase and the vaginal epithelium becomes cornified.
