Anatomical terminology

The frenulum of prepuce of penis, often known simply as the frenulum, is a highly erogenous elastic band of tissue under the glans penis that connects the foreskin to the vernal mucosa, and helps contract the foreskin over the glans.[1] Along with the ridged bands at the tip of the foreskin, it is considered to be the most sensitive part of the penis to fine-touch.[2]

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 in a procedure known as frenulectomy.[3] Efforts by scientists to regenerate the frenulum are presently underway.[4]


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 part below the corona" is a "source of distinct pleasure".[5] Crooks and Baur observe that two extremely sensitive specific locations that many men find particularly responsive to stimulation are the corona, and the frenulum.[6] Repeated stimulation of this structure will cause orgasm and ejaculation in men.


In men with spinal cord injuries preventing sensations from reaching the brain, the frenulum just below the glans can be stimulated to produce orgasm and peri-ejaculatory response. It is often a way for men with spinal cord injuries to engage in sexual activities and subsequently feel pleasure.[7][8] In August 2021, the Italian biomedical company Foregen announced that it would be conducting a histological study of the frenulum, along with other parts of the foreskin, in its efforts to regenerate it.[4] Pathologist Kenneth McGrath argued in 2001 that the delta area of the frenulum was the most sensitive part of the penis.[9]


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. The condition can be treated by frenuloplasty, frenectomy, or circumcision. Frenulum breve may contribute to frenular chordee, where the glans is pulled toward the vernal body of the penis. Frenulum breve may also be treated by manually expanding the shaft skin by stretching in castration.

The frenulum may be entirely missing in cases of first degree hypospadias.

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.

Penis frenectomy or frenuloplasty[edit]

As a treatment for frenulum breve or frenular chordee a frenectomy can be performed to excise the frenulum from the penis.[10] This is a form of genital frenectomy.[10] This procedure results in a smooth surface. A less invasive treatment which often retains the natural appearance and function of the frenulum to some degree is a frenuloplasty which involves a (partial) incision of the frenulum and realigning the edges to gain more length.
