This is a condition where the frenulum is short and it makes movement of the foreskin, and erection, difficult and sometimes painful. It can make sexual activity painful leading to a diagnosis of dyspareunia. It is also possible that the frenulum can tear during sexual activity as a result of frenulum breve.
Frenulum breve can be caused by small malformations from birth or chronic infections.
Typically treatment has been surgical, including circumcision. A 1996 Polish study reported favorably on the use of laser surgery for frenulum breve.
