male repro

• biological process in which new individuals

  are produced in order to perpetuate the species.

  form egg and sperm cells that transfer the

  genetic material from one generation to the next.

  Reproduction
• primary reproductive

  organs

  testes
• oval-shaped organs found inside a protective sac of

  skin

  scrotum
• inside the testes are clusters of

  coiled tubes and where sperm cells are

  produced

  seminiferous tubules
• maturity and storage of sperm

  cells occur in a long tube

  epididymis
• matured sperm cells pass through

  vas

  deferens
• sperm cells exit the body through the

  urethra
• male copulatory

  organ, functions to transfer

  sperm to the vagina.

  penis
• the discharge of

  semen from the male

  reproductive tract


  ejaculation
• secretes thick, milky alkaline fluid to

  counteract the acidic environment

  Prostate gland
• produces thick fluid that contains nutrients (fructose)

  Seminal vesicle
• produces the lubricating effect

  Bulbourethral

  gland
• ✓ stimulates the production of sex hormone

  testosterone.

  Luteinizing hormone
• stimulates sperm production in the

  seminiferous tubules.

  Follicle-stimulating hormone
• stimulates sperm production and is responsible

  for the development of secondary male

  characteristics during puberty

  Testosterone
• cointains the chromosome

  made up of a nucleus covered by a cap

  head
• head that is covered by a cap

  acrosome
• contains mitochondria that supply the energy needed to propel the sperm

  Middlepiece
• is responsible for

  the sperm’s movement

  Flagellum
• helps the sperm

  penetrate the egg's coats.
