Have endometrial hyperplasia, no abnormal bleeding (app. 11mm @ day 13 of cycle). dr. advises ablation. is that recommended? please explain.

No: Your are 44 years old, are you still having your periods? If you are, then 11 mm endometrial thickness is not considered endometrial hyperplasia in a menstruating woman. Besides, even if you were postmenopausal endometrial hyperplasia may imply dysplasia or cancer and ablation is the wrong thing to do since you may mask a cancer. If you have no abnormal bleeding then ablation is not indicated.
