Estrella How the Male Reproductive System Works • Testes (testicles) male reproductive organs that produce sperm and testosterone. • The scrotum is a sac containing the testes. Muscles in the scrotum move the testes closer to or further from the body to regulate temperature. Chapter 18 Section 1 Male Reproductive System Human Sperm under scope
  7. 7. Copyright © by Holt, Rinehart and Winston. All rights reserved. R.G. Estrella Hormones: are chemicals that send messages. Testosterone is the major male sex hormone.

  13. 13. Copyright © by Holt, Rinehart and Winston. All rights reserved. R.G. Estrella 3 Sexual Glands in men: – Prostate Gland: about 1/3 of the semen. Makes a “basic” fluid that removes acid in the vagina. – Seminal Vesicles: make fructose “sugar”, 70% of semen. – Bulbourethral (Cowper’s) gland: makes pre-cum. Lubricates the urethra & cleans it of urine.
  14. 14. Copyright © by Holt, Rinehart and Winston. All rights reserved. R.G. Estrella How the Male Reproductive System Works • Urine passes from the urinary bladder into the penis through the urethra. • Sperm from the testes travels from the epididymis through the vas deferens. Sperm mix with glandular fluids in the vas deferens to make semen and goes into the urethra and out of the penis. Chapter 18 Section 1 Male Reproductive System
