TESTOSTERONE CONTROL
---NEGATIVE FEEDBACK (Decreases production of sex hormones if the levels of sperm and testosterone are too high) [homeostasis]---
*Main control centre: HYPOTHALAMUS (brain)
*HYPOTHALAMUS releases GnHR (gonadotropin releasing hormone) targeting the ANTERIOR PITUITARY
* ANTERIOR PITUITARY secretes:
- LH (Lutenizing Hormone):
- Targets the testes (Interstitial Cells that produce testosterone)
- Increases Testosterone Production
- FSH (Follicle Stimulating Hormone)
- Targets testes (Seminiferous Tubules that produce sperm)
- Increases Sperm Production
**HYPOTHALAMUS KEEPS TESTOSTERONE AND REPRODUCTIVE HORMONE LEVEL IN CHECK WITH NEGATIVE FEEDBACK WITHHOLDING PRODUCTION OF KEY HORMONES WHEN NECESSARY**
- Targets the testes (Interstitial Cells that produce testosterone)
- Increases Testosterone Production
- Targets testes (Seminiferous Tubules that produce sperm)
- Increases Sperm Production
