  • Reproductive system
    Responsible for producing offspring. Includes male and female specific organs to complete offspring production.
  • Theriogenology
    Animal reproduction or the study of producing beasts.
  • Theri/o

    Beast
  • Gen/o

    Producing
  • -logy
    To study
  • Genitals or genitalia

    Male or female reproductive organs
  • Genit/o

    Organs of reproduction
  • Male reproductive system
    Functions to produce and deliver sperm to the egg to create life. It is composed of the scrotum, testes, epididymis, ductus deferens, accessory sex glands, urethra, and penis.
  • Scrotum or scrotal sac

    The external pouch that encloses and supports the testes. It keeps them outside the body at a lower body temperature for sperm development.
  • Scrot/o

    Scrotum
  • Perineum
    The area between the scrotum and anus in males or the vulva and anus in females.
  • Perine/o

    Perineum
  • Testes or testicles
    Male sex glands that produce spermatozoa.
  • Testis
    A single testes gland
  • Gonads
    Sex glands
  • Orch/o, orchi/o, orchid/o, test/o, and testicul/o

    Testes
  • Spermatic cord
    Suspends the testes in the scrotum
  • Seminiferous tubules
    Coiled tubes contained in the compartments of the testicles. They are channels that where sperm is produced and through which they live the testicles.
  • Leydig's or interstitial cells

    Cells between the spaces in the testicles that have endocrine function.
  • Sertoli cells
    Specialized cells in the testicles that support and nourish sperm growth.
  • Sperm or spermatozoa
    Male gametes
  • Spermatozoon
    One gamete
  • Sperm/o and spermat/o
    Spermatozoa.
  • Acrosome
    Structure at the top of the head of sperm that contains enzymes that allow them to penetrate the ovum.
  • Spermatogenesis
    Production of male gametes.
  • Head
    Part of the sperm with a nucleus and acrosome.
  • Midpiece
    Middle part of the sperm that contains mitochondria.
  • Flagella or tail
    End of the sperm that allows for movement.
  • Gamete
    Sex cells
  • Epididymis
    Formed from a duct the emerges from a cluster of seminiferous tubules. It is at the upper part of each testis that secretes part of the semen, stores semen before ejaculation, and provides a passageway for sperm. It runs down the length of the testicles, turns upward, and becomes the ductus deferens. This is where sperm become motile.
  • Motile
    Capable of spontaneous motion.
  • Epididym/o

    Epididymus
  • Ductus deferens
    A tube connected to the epididymis that carries sperm into the pelvic region toward the urethra. It is encased by the spermatic cord and is the excretory duct of the testes.
  • Ampulla
    Glandular portion of the ductus deferens in swine. It is an enlarged part of the tube or canal.
  • Male accessory sex glands

    Includes the seminal vesicles, prostate gland, and bulbourethral glands. They add secretions to the sperm and flush urine from the urethra before sperm enters it.
  • Seminal vesicles or vesicular glands
    Two glands that open into the ductus deferens where it joins the urethra. It secretes a thick, yellow substance that nourishes the sperm and adds volume to the semen.
  • Semen
    The ejaculatory fluid that contains sperm and the secretions of accessory sex glands.
  • Semin/i

    Semen
  • Ejaculatory duct
    Formed by the union of the ductus deferens and the duct from the seminal vesicles. It passes through the prostate and enters the urethra.
  • Prostate gland
    A single gland that surrounds or is near the urethra and may be well defined or diffuse depending on the species. It secretes a thick fluid that aids in the motility of sperm.
