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".

Cepeda-Emiliani et al (2023) state:
<blockquote>
One circumcision technique [91] has been proposed to protect
as much tissue as possible ventrally due to the sexual functions
attributed to this region. Concerningly and antithetically to the
former technique, the frenular area has been intentionally
targeted during [[adult circumcision]] by some urologists in
the belief that its total and permanent denervation using
monopolar current might be a definitive treatment for lifelong
premature ejaculation. These urologists concluded that
their circumcision technique resulted in “a consistent reduction
in penile sensitivity” and “is a strong weapon in the hands of
urological surgeons, which must be used very carefully, as its
effects on male sexuality can be devastating and irreversible
if performed in the wrong patient. Thus, the caveat must be
right circumcision in the right patient using the correct
surgical technique’”. To the extent that
this type of circumcision may impair sexual function by
denervating a neurologically permissive substrate through which
sexual sensation enters the central nervous system, we agree
with Jannini [93] that denervation of the frenular region is a
potentially dangerous intervention.<ref name="cepeda2023">{{REFjournal

[[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 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.

==Protection of the frenulum==
Tearing the frenulum during penetration is not uncommon. Men with a short frenulum should observe precautions when penetrating their partner. When penetration occurs the vaginal wall will tend to push the foreskin to a retracted position and that is likely to strain the frenulum and may cause it to tear. The frenular artery, which supplies blood to the [[glans penis]], passes through the frenulum. If it is torn, significant bleeding may occur.
Men should delay penetration until foreplay has sexually aroused the partner and caused her to be lubricated. If her [[vagina]] does not lubricate, then personal lubricant should be applied prior to penetration. One should penetrate slowly and carefully to avoid placing excessive strain on the frenulum.
