Frenulum vs. Fourchette: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on March 6, 2024
The frenulum is a small fold of tissue that secures or restricts the motion of a mobile organ in the body; the fourchette is the fold of skin at the posterior part of the vulva.

Key Differences

The frenulum is found in various body parts, such as under the tongue or the penile shaft. The fourchette is located specifically at the posterior part of the vulva.
Frenulums serve to restrict and secure the movement of the organ they are attached to. The fourchette is primarily a structural feature of the vulva, marking the lower boundary of the vaginal opening.
Issues with frenulums can lead to conditions like tongue-tie or frenulum breve. The fourchette can be subject to tearing or stretching during sexual activity or childbirth.
Surgical procedures can alter or remove frenulums for medical reasons. The fourchette may be involved in surgical procedures like episiotomies during childbirth.
Frenulums vary in size and elasticity among individuals. The fourchette also shows variability and can change due to hormonal influences or physical events like childbirth.

Frenulum and Fourchette Definitions


Varies in form and function across the body.
The frenulum's elasticity is crucial for normal organ function.


May be involved in episiotomies.
An episiotomy during childbirth might involve the fourchette.


A small fold of tissue connecting two parts of the body.
The frenulum under his tongue was short, limiting movement.


Marks the lower boundary of the vaginal opening.
The fourchette defines the vaginal opening's lower edge.


Restricts the movement of the organ it's attached to.
The frenulum's tightness sometimes requires surgical intervention.


A fold of skin at the vulva's posterior part.
The fourchette is located at the back of the vulva.


Commonly found under the tongue.
A tight oral frenulum can affect speech.


Changes due to hormonal or physical influences.
Hormonal changes during puberty can affect the fourchette's appearance.


(Anatomy) A small frenum.


(Entomology) A bristly structure on the hind wings of certain moths and butterflies that holds the forewings and hind wings together during flight.


(anatomy) A small fold or ridge of tissue that supports or restrains the motion of the part to which it is attached, in particular a fold of skin beneath the tongue, or between the lip and the gum.
Humans have three oral frenulums: beneath the tongue, between the upper lip and gum, and between the lower lip and gum.


A bristle or row of bristles on the edge of the hindwings of some lepidoptera which unites the wings by interlocking with a catch on the posterior part of the forewings.
