Structure:

The deep fascia of the penis is a dense layer of connective tissue that surrounds and supports the erectile structures of the penis.[1] It lies deep to the superficial penile fascia (dartos fascia) and envelops the corpora cavernosa and the corpus spongiosum.[1] The superficial dartos fascia is located immediately beneath the skin of the penis and contains smooth muscle fibers. While the dartos fascia is continuous with the dartos layer of the scrotum, the deep fascia of the penis forms a distinct, deeper layer that provides firm structural containment for the erectile tissues.[1] It also plays an important role in clinical anatomy, particularly in urology and penile surgery. Its integrity is relevant in conditions such as penile fracture, Peyronie’s disease, and during procedures including penile prosthesis implantation, where accurate identification of fascial layers is essential.[1]
