Hi I read it in a book called
Mastering menopause by Emine Cay Masters, M.D., FACOG.
I got it free on my kindle and found it quite easy to read. She states that ADs increase the pituitary glands secretion of prolactin and elevated prolactin levels supress ovarian function resulting in low estrogen levels. I find it all very intriguing and I'm sure I read something else about this but can't recall where at the moment. X
