Smegma is a thick, whitish substance that can accumulate under the foreskin of the penis. It is composed of dead skin cells, oils, and bacteria. While smegma is a normal bodily secretion, excessive amounts can lead to irritation, infection, and other health problems. Fortunately, there are a few simple steps that men can take to avoid smegma buildup.
Good hygiene is the most important factor in preventing smegma. Men should wash their genitals daily with soap and water. It is also important to retract the foreskin and clean underneath it. If smegma does accumulate, it can be removed with a cotton swab dipped in warm water. In some cases, a doctor may recommend using a topical antibiotic cream to treat smegma-related infections.
