Male genital organs

The male genital organs refer to the structures involved in reproduction and the production and transport of sperm. These organs are typically divided into:

• External genitalia:

  • 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.

• Internal genitalia:

  • Testes: Paired glands that produce sperm and testosterone, usually located in the scrotum.

  • Epididymis: A coiled tube where sperm mature and are stored.

  • Ductus deferens (vas deferens): Transports sperm from the epididymis to the urethra.

  • Tunics of spermatic cord and testis

  • Accessory sex glands: Include the vesicular glands (seminal vesicles), prostate, and bulbourethral glands (depending on species), which produce seminal fluid to nourish and transport sperm.
