The fundiform ligament of the penis is a structure of the external genitalia whose descriptions differ according to the source consulted.
The 41st Edition of Gray's Anatomy (2015) and Traité d'Anatomie humaine do not acknowledge this structure. Some sources equate the fundiform ligament with the Scarpa fascia.
Although rarely mentioned, this ligament is also found in females (at the clitoris).
Research
A 2023 cadaveric study on 7 cadavers characterised the fundiform ligament as a structurally heterogenous structure that is superficial to the suspensory ligament of penis. The study identified three morphological types/variants of the fundiform ligament: a single triangular structure (attached proximally onto the linea alba); a doubled structure with accessory bundles (one medial main band and one lateral accessory band on each side); and an amorphous, ligamentous fibrous connective band structure.
