Male Reproductive System

Vas Deferens:

  • Two long narrow tubes leading out of the epididymis
  • Carry sperm to the urethra

Seminal vesicles:

  • Two small organs about the size of a finger located behind the bladder
  • Produce nourishing fluid to give sperm energy to move

Prostate Gland:

  • The size and shape of a chestnut
  • Secretes fluid to help move sperm
  • Vas deferens tubes join urethra at prostate gland

Cowper’s gland:

  • Pea sized glands that connects to the urethra via a tiny duct
  • Secrete thick, clear mucus prior to ejaculation
male disorders

  • If the Testes fail to descend from the abdomen by the 1st year, hormone medication and/or surgery

Inguinal hernia:

    • Intestine may push through into the scrotum
    • Surgery

Testicular Cancer:

    • A cancer of the Testes that can affect males ages 15-35
    • Can be treated if found early, may be detected during a self examination
    • Symptoms: painful urination, blood in semen, general discomfort, enlarged testes, lumps

Prostate Cancer:

interesting facts about the male did you know
Interesting Facts Aboutthe Male DID YOU KNOW……………
  • 200 million to 600 million sperm cells may be deposited in the vagina by a single ejaculation.
  • Of those 200 – 600 million only a few hundred ever reach the egg.
  • If the sperm does not meet the egg they are either killed by acid, deformed, or they don’t complete the journey.
  • The male testes produce millions of sperm daily.
  • Sperm account for 1/10 of the volume of semen.
  • The journey to the fallopian tube for the sperm cells takes less than an hour following sexual intercourse.

More interesting Facts about the male…
  • Although many sperm cells may reach the egg, in most cases only one will actually fertilize it.
  • The female egg may survive for only twelve to twenty-four hours following ovulation.
  • Sperm may live up to seventy-two hours (three days) within the female reproductive tract.
  • Ejaculation: muscle contractions that push semen through the urethra and out the penis.
  • Nocturnal emissions (Orgasm): normal ejaculation of semen during sleep.
  • There is no average size penis when it is soft – most adult erections are the same size: 5 ½ - 6 inches long.
