Gamete Production and Fertilisation

• Where are sperm produced?

  Testes - Seminiferous tubules
• In the male reproduction system, germline cells divide by mitosis to produce more germline cells or by meiosis to produce sperm
• Describe the function of an Interstitial cell

  Produces and secretes Testosterone
• Where is semen produced? (2)

  Seminal vesicles and the prostate gland
• What is the function of the fluids (semen) secreted by the prostate gland and seminal vesicles?

  Maintains the mobility and viability of the sperm
• What do seminal vesicles secrete?

  a fructose rich liquid
• What is the function of the fructose rich liquid that is secreted by seminal vesicles?

  1. provides energy for the mobility of the sperm

  2. stimulates the female to make contractions to take the sperm up
• What does the prostate gland secrete?

  a thin lubricating liquid
• What does the thin lubricating liquid contain?

  Enzymes which regulate the viscosity of semen
• What is contained in the ovaries?

  Immature ova at various stages of development
• What happens during the development stage of the ovum?

  Each ovum is surrounded by a follicle that protects the developing ovum and secretes hormones
• Briefly describe the events that lead to fertilisation

  Mature ova are released into the oviduct where they may be fertilised by sperm to form a zygote
