Study Notes
Hormone Regulation of Spermatogenesis
- FSH (Follicle-Stimulating Hormone) initiates spermatogenesis.
- Testosterone plays a crucial role in males by promoting the development of male characteristics and reproductive organs.
Testosterone Production Regulation
- Testosterone production is regulated by a negative feedback loop involving the hypothalamus, anterior pituitary, and testes.
Inhibin Production
- Sertoli cells in the seminiferous tubules of the testes produce inhibin.
Anterior Pituitary Stimulation
- Gonadotropin-Releasing Hormone (GnRH) from the hypothalamus activates the anterior pituitary to produce LH (Luteinizing Hormone) and FSH.
Leydig Cell Stimulation
- LH stimulates Leydig cells to produce testosterone.
Testosterone and Inhibin Relationship
- Testosterone inhibits the production of FSH by stimulating the production of inhibin, which in turn inhibits FSH production.
