Male reproduction

• What does the vas deferens carry?

  Sperm from the testes
• What is the function of the seminal vesicles?

  They secrete fluid that makes up semen
• Where are the testes located?

  In the scrotum outside the body
• What is the role of hormones produced by the pituitary gland in male reproduction?

  They trigger testosterone release
• What is the purpose of the scrotum?

  To keep testes at a lower temperature
• What happens to sperm in the epididymis?

  They mature and start to swim
• What is the vas deferens?

  A thick muscular tube carrying sperm
• What is the function of the prostate gland?

  Produces fluid that nourishes sperm
• What percentage of semen is produced by seminal vesicles?

  50-70%
• What type of fluid does the prostate gland produce?

  Slightly alkaline, milky or white fluid
• How does the urethra function in the male reproductive system?

  It carries both urine and sperm
• What is the role of the urethra?

  Extends from the bladder to the penis
• What happens during a vasectomy?

  The vas deferens is closed off
• What is the significance of sperm motility?

  It allows sperm to swim and reach the egg
• What is the size of the prostate gland?

  Walnut-sized
• What does the alkaline fluid produced by the prostate gland do?

  Supports and nourishes the sperm
• How does sperm maturation affect its survival?

  It increases motility and DNA protection
• What are the main components of the male reproductive system?

  • Testes
  • Epididymis
  • Vas deferens
  • Seminal vesicles
  • Prostate gland
  • Urethra
• What is the process of sperm transport in the male reproductive system?

  1. Sperm produced in testes
  2. Mature in epididymis
  3. Travel through vas deferens
  4. Mixed with seminal vesicle fluid
  5. Pass through prostate gland
  6. Exit via urethra
• What do the prostate and seminal vesicles mix with to form semen?

  Secretions (fluid)
• Why are the secretions from the prostate and seminal vesicles essential?

  They maintain sperm in a motile and viable state
• What does motile mean in the context of sperm?

  Can move
• What does viable mean regarding sperm?

  Healthy and can fertilize an egg
• Which gland mainly controls the endocrine hormonal system?

  Pituitary gland
• What is controlled by the pituitary gland in relation to male reproductive health?

  Messages about hormone secretion
• How does the pituitary gland relate to sperm production?

  It controls hormone secretion relevant to sperm production
• What are the roles of the prostate and seminal vesicles in male reproduction?

  • Mix secretions with sperm to form semen
  • Maintain sperm in a motile state
  • Ensure sperm are viable for fertilization
