What is smegma definition?

Smegma is a natural, white substance that accumulates in the folds of the male or female genitalia. It is made up of dead skin cells, oils, and other bodily fluids. Smegma is harmless and most people produce it, but it can sometimes cause odor or discomfort if not cleaned regularly. Proper hygiene and cleaning of the genital area can help prevent the buildup of smegma. In males, smegma can accumulate under the foreskin of an uncircumcised penis and may need to be removed regularly. In females, smegma can accumulate in the folds of the labia minora and around the clitoral hood.
