Parts of the penis and scrotum

  • The Penis
    The shaft of the penis is formed by three columns of erectile tissue full of blood vessels, bound together by fibrous tissue. At the end of penis is the cone-shaped glans.

  • The glans
    The glans is the head of the penis. Prepuce usually covers the glans. The glans, as well as the corona - the ridge of flesh that connects the glans to the shaft of the penis - is highly sensitive.

  • The corona
    The 'crown' a ridge of flesh denoting the junction of head of the penis with the shaft.

  • The frenulum
    A thin strip of flesh on the underside of the penis that connects the shaft to the head.

  • The prepuce (foreskin)
    In uncircumcised males, the glans is covered by a loose, hood-like foreskin called the prepuce, which rolls over and covers the head of the penis. Prepuce is what is removed during circumcision.

  • The urethral meatus
    The opening at the tip of the penis to allow the passage of both urine and semen.

  • The smegma
    A cheese like substance secreted by glands on each side of the frenulum in uncircumcised men.

  • The scrotum
    The scrotum is loose, wrinkled pouch of skin that hangs behind and below the penis, divided into two compartments, each of which contains a testicle. The scrotum is a sac, and contains the testes, the male sexual glands. The scrotum's primary function is to maintain the testes at approximately 34 C, ideal temperature for testes to produce sperm effectively.
