I wonder if there is anything that can safely bind neural estrogen receptors that doesn't have cause the physical changes?

This might work. (Good luck finding some, though.) "We recently discovered that ICI 182,780 (1), an antagonist of estrogen receptor (ER)-dependent proliferation in reproductive tissues, functions as an estrogenic agonist in primary neurons."
