Newbie question on aromatase inhibition

[thx138]

Hello, I take finasteride for BPH. After a year on it I think I'm developing gynecomastia. I don't seen anything in the mirror but in discussions with others the first sign can be nipple sensitivity. Not in the pleasureable sense, more of irritation. I can feel shirt fabric rubbing against the nipples. A blood spot test showed Estradiol 27 (12-56) and testosterone 453 (400-1200). I've used DIM but don't know whether it's working. I'd like to try Femara, a relatively new aromatase inhibitor. Anyone have experience with this?

Thanks,
