White Stuff on Labia Majora, Labia Minora

Regardless of sexual activity at times women notice a build up of white stuff or residue on their labia majora and labia minora (clitoris and vulva area). The medical term for this build up is smegma.

Smegma gathers in the nooks and crannies of the body’s skin folds, including between the labia and around the clitoral hood.

Smegma is a natural lubricating residue made up of shedded skin cells, skin oil secretions, and moisture, including sweat.  Smegma’s pasty, cheesy like appearance can vary in color from almost white to a darker shade, depending on a person’s skin tone.

Smegma gathers in men under the foreskin of uncircumcised penises. Because of male circumcision, smegma is more common among women than men.

Smegma is known for is its characteristic smell, which some find arousing and others find unpleasant. If the build up of smegma is worrisome, it can be gently wiped away with a cotton swap or rinsed away with warm water. Keep in mind, the vulva area, the labia majora, labia minora and clitoris skin is sensitive, avoid applying soap to the area. Soap tends to be drying and the natural secretions (moisture) of the labia and clitoris provide suppleness and comfort.

If a regular warm water rinse between the labia does not produce enough of an improvement in vulva aroma, consider seeing a healthcare practitioner or gynecologist for a check-up.
