Ventral view of a circumcised penis, with frenular delta proximal to the glans penis

The frenular delta in human anatomy is the triangular area underneath the penile glans along the penile ventral body, and is composed of a mucosa.^[1] The frenulum attaches at the top of the triangle and outlines its sides, which connect with the ridged bands. The delta is highly innervated, and is considered a specific erogenous zone.^[2] The frenular delta is sometimes removed during male circumcision.
