Difficult anatomy and physiology question!!!!?

well, In number 1) the GnRH causes the release of FSH, not the way you wrote it there. (Gonadotropin-Releasing Hormone stimulates the release of Follicle Stimulating Hormone, you have it backwards.) In number 2, LH doesn't stimulate the pituitary to release FSH, that's GnRH again. I'm not aware that testosterone stimulates more testosterone production...that's a positive-feedback loop and those are rare, but you may want to google it or look elsewhere. Hope it helps.
