If anyone could tell me if I have this right it would be great, I get a little different info from different sources.
Estrogen production in the ovaries stimulates GnRH in the hypothalamus. This triggers the anterior pituitary to manufacture FSH and LH. LH triggers ovulation.
Decreased GnRH causes production of FSH, which stimulates the follicles to...there is my question I guess. I have read in my text that it simply controls FSH and LH production. But from different sources I understand that an increase triggers ovulation and a decrease stimulates FSH so the whole process can start over again.
I am supposed to understand the positive and negative feedback each of these creates on target tissues. Unfortunately, nothing in my text covers this. HELP!
