I am not sure femara is better than clomid, but in theory there are a couple of good reasons for femara
in your case. First, there are case reports of endometriosis
being treated successfully by aromatase inhibitors, which is the class of drug femara is from. Second, femara results in a thicker, better looking endometrium, than clomid. On the other hand, femara is more likely to result in one egg being released, rather than multiple.
