The frenulum of prepuce of penis, often known simply as the frenulum, is an elastic band of tissue under the glans penis that connects the foreskin (prepuce) to the vernal mucosa, and helps contract the foreskin over the glans. In the event of frenulum breve or frenular chordee, or to ensure that the glans can be freely and completely exposed, the frenulum may be partially or totally removed. It is also often removed in a circumcision.
