Components of the Reproductive (Hypothalamus, Pituitary, Testis) Axis
- Hypothalamus
- Produces GnRH
- GnRH
- Simulates production and release of LH and FSH from anterior pituitary
- Patterns of secretion (3):
- Seasonal (peaking in spring)
- Circadian (highest testosterone in morning)
- Pulsatile, peaks every 90-120 minutes
- Pulsatility arises at puberty, around age 12
- GnRH
- Produces GnRH
