Hyde, i have low E2 also. My E2 was 71 (normal range 75 - 178). Even when my total t was at 25.2nmol my E2 was only at 73! When my E2 was 71 (on 10g's of androgel daily) i wasn't getting morning wood either. Low E2 can give the same symptoms as high E2.
Do you have any other symptoms of low e2 (Dry Skin being one)? How's the libido looking?
