Penis Anatomy

A Flash diagram of the anatomy of a human penis. The shaft of the penis is made of three columns of tissue called 'corporeal bodies': two corpora cavernosa and one corpus spongiosum. In most boys, the foreskin encloses the glans at birth, but in hypospadias the foreskin is incomplete, looking like a ‘hood’ on the back of the glans instead, while the opening (meatus) of the urethra is also located on the underside of the penis (between the penis and scrotum, in the scrotum, or underneath the scrotum on the perineum) in hypospadias, instead of at the tip of the glans. See how a penis with midshaft hypospadias differs from one without, and roll-over different parts of the diagram for their labels.
