A '''frenulum''' (or '''frenum''', plural: '''frenula''' or '''frena''', from the Latin ''frēnulum'', meaning "little bridle") is a small fold of tissue that binds movable structures to non-movable structures in the body. In the human body, examples of frenula include the frenulum linguae, under the tongue, the frenulum labii superioris inside the upper lip, and the ''frenulum labii inferioris'' inside the lower lip. The word ''frenulum'' on its own is often used for the frenulum in the human [[penis]], which is an elastic band of tissue under the [[glans penis]] that connects to the [[foreskin]] to the vernal [[mucosa]], and helps contract the prepuce over the glans. This is sometimes colloquially known as the "banjo string".

The frenulum and the associated tissue delta on the underside of the [[penis]] below the [[corona ]] has been described in sexuality textbooks as "very reactive" and "particularly responsive to touch that is light and soft." The “underside of the shaft of the penis, meaning the body below the corona” is a “source of distinct pleasure.”<ref name="hass1993">{{REFbook

In men with spinal cord injury preventing sensations from reaching the brain, for example, the frenulum just below the [[glans ]] can be stimulated to produce orgasm and peri-ejaculatory response.<ref>{{REFweb

[[Frenulum breve]] is a condition in which the frenulum is short and restricts the movement of the [[foreskin]], which may or may not interfere with normal sexual activity. Frenulum breve may be treated by manually [[tissue expansion| expanding]] the [[shaft skin ]] by [[stretching]]. The condition may also be treated by [[frenuloplasty]], or [[frenectomy]]. Frenulum breve may contribute to frenular chordee, where the glans is pulled toward the vernal body of the penis.

It is possible for the frenulum to tear during sexual activities. The [[frenular artery]], a branch of the dorsal artery, may be severed, causing significant [[bleeding]].

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]].<ref name="Griffin-Kroovand1990">{{REFjournal

Song ''et al''. (2015) report that the frenulum may need to be lengthened after a [[circumcision ]] amputates [[skin ]] tissue from the [[penis]].<ref>{{REFjournal

Rarely, boys are born without a frenulum. This condition causes no issues and permits unusually full complete retraction of the [[foreskin]].

It may be missing in men who were [[circumcised ]] at birth, as it is often crushed and cut away, or broken during infant [[circumcision]]. Men who are circumcised as adults may specify whether or not they wish to preserve their frenulum. The frenulum was reported to be cut in 26.7%, 20%, and 33.33% of [[circumcised ]] patients in various surveys.<ref name="Griffin-Kroovand1990"/><ref name="Gary2000"/>
