Deep to the skin lies the superficial (dartos) and deep (Bucks’) fascia, which supply additional structural support ( 2). The skin is firmly attached to the glans and only loosely attached to the shaft, allowing for mobility during intercourse. If infection or trauma do occur, the skin can impair intracavernosal functioning and result in a contained abscess or hematoma formation, respectively. Skin plays an important role in protecting the penile tissues from trauma during intercourse and as a barrier from bacterial infection.

Each layer of the penis plays a significant role in the function and dynamics of the penis during sexual activity and voiding ( 1). The main components of the penis are surrounded by areolar tissue and peripherally encased with skin. The penis is composed of three large cylinders-two corpora cavernosa dorsally, which contain the erectile tissue, and the corpus spongiosum which constitutes the urethra. To fully understand limitations of small penis size and the surgical correction possibilities, we must review the relevant basic penile anatomy.
