  3. Male Reproductive Organs(Front View) 11 (Cowper’s Gland)

  4. Male Reproductive System Epididymis: • Two tightly coiled tubes that rest on top of the testes • Sperm move and mature Testes or testicles: • Two small glands that produce sperm • They produce male hormone testosterone • They hang outside the body in the scrotum Scrotum: • External sac of skin that hold testes • Protects testes • Regulates Temperature

  5. Male Reproductive System Foreskin: • A retractable double-layered fold of skin and mucous membrane that covers the glans penis. Penis: • Spongy tissue • Means for sperm and urine to exit the body • Male external organ Urethra: • Tube that carries semen and urine through the penis Bladder: • The organ that collects urine excreted by the Kidneys prior to disposal by urination

  6. 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

  7. SEX EDUCATION Male disorders

  8. Male disorders- Circumcision: • Removal of the foreskin • Generally removed as an infant Undescended Testes: • 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: • This is most common in men 65 years of age • Easily treated if detected early • All men over forty should be tested • Symptoms: painful & frequent urination, blood in semen/urine, general discomfort, enlarged testes, lumps

  9. 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.

  10. 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. • Hole’s Human Anatomy & Physiology Ninth Edition
