== Introduction ==
* Reproductive behaviour can only take place if the neurons in the [[Endocrine_System_-_Hypothalamus_-_Anatomy_%26_Physiology#Hypothalamus|hypothalamus]] have been sensitized to respond to sensory signals.
* Reproductive behaviour can only take place if the neurons in the [[Endocrine_System_-_Hypothalamus_-_Anatomy_%26_Physiology#Hypothalamus|hypothalamus]] have been sensitized to respond to sensory signals.

== Male ==
* In the male, testosterone is aromatized to oestradiol in the brain. Oestradiol promotes reproductive behaviour.
* In the male, testosterone is aromatized to oestradiol in the brain. Oestradiol promotes reproductive behaviour.
* Testosterone is produced in small episodes every 4-6 hours.
* Testosterone is produced in small episodes every 4-6 hours.
* Relatively constant supply of testosterone, thus oestradiol, to the [[Endocrine_System_-_Hypothalamus_-_Anatomy_%26_Physiology#Hypothalamus|hypothalamus]].
* Relatively constant supply of testosterone, thus oestradiol, to the [[Endocrine_System_-_Hypothalamus_-_Anatomy_%26_Physiology#Hypothalamus|hypothalamus]] in the male.
* This allows the male to initiate reproductive behaviour at any time.
