External male genitalia

Partes genitales masculinae externae

Definition

Antoine Micheau

the external male genital organs refer to the reproductive structures visible externally. These typically include:

  • Penis: Organ used for copulation, varying significantly in shape and structure among species (e.g., fibroelastic in ruminants and pigs; musculocavernous in horses, dogs, and cats).

  • Male urethra

  • Prepuce: Fold of skin that covers the free part of the penis when not erect.

  • Scrotum: Skin-covered sac housing the testes, helping regulate temperature for optimal sperm production.
