BACK TO REPRODUCTIVE SYSTEM
BACK TO REPRODUCTIVE BEHAVIOUR



Sensitization

  • Reproductive behaviour can only take place if the neurons in the hypothalamus have been sensitized to respond to sensory signals.


Male

  • Testosterone is aromatized to oestradiol in the brain. Oestradiol promotes reproductive behaviour.
  • Testosterone is produced in small episodes every 4-6 hours.
  • Relatively constant supply of testosterone, thus oestradiol, to the hypothalamus in the male.
  • This allows the male to initiate reproductive behaviour at any time.


Female

  • Only experiences high oestradiol during the follicular phase.
  • Will only display sexual receptivity during oestrus.
