The frenulum of prepuce of penis is the fold of the skin in charge of attaching the underside of the glans with the inner surface of the foreskin. Its function is to help to contract the prepuce on the glans. Short frenulum is when the frenulum is so short that it restricts the movement of the foreskin, which causes discomfort during sexual activity. One of the consequences is that it can get torn, causing pain and some bleeding, which is not a medical emergency, but if it gets complicated it requires medical treatment. There are different methods for this: from the use of creams with corticosteroids and exercise for the manual extension of the frenulum, to repair plastic surgery (fenuloplasty), elimination (fraenectomy) or circumcision.
