Document Summary
In 1889, charles-edouard brown-sequard injected himself with extract (dog/g. pig) Wwii german scientists: chronic wasting (pow/concentration camp, soldier supplement (increase aggression, adolph hitler. Secreted from the testes and ovaries: only the levels of testosterone is different (more for men, less for women) Testes + sterol + ketone = testosterone. Endogenous anabolic steroid: a compound we produce ourselves. Negative feedback system: testosterone levels detected by hypothalamus r, low levels cause release of grf (gonadotropin-releasing factor) Grf stimulates pituitary to produce: fsh (follicle-stimulating hormone, lh (luteinizing hormone) Induce spermatogenesis: synthesis/release of testosterone (by leydig cells) As levels of testosterone increase, it will tell the hypothalamus to slow down, that it has enough, and therefore there will be less grf released, meaning there will be less fsh and lh released. Negative feedback loop because as levels increase, it is sending an inhibitory signal back to the hypothalamus to pull back. Steroids come in and mess up the whole system.
