Charli'smumma i know many endo's like to do the surgery on women who are still of childbearing age, because it removes any potential problems re: babies etc. If you already have a kid you cannot be in close physical contact with them for the first few weeks, and if you fall pregnant within 6 months it can be pretty much horrifically disastrous for the foetus - NO contraceptive is 100%, only 6 months of abstinence would be the sure thing, and it might cause problems within a relationship to have to do that.

Thyroid problems are VERY common in post-menopausal women, women who do NOT have to care for a baby 24/7, will NOT fall PG, accidentally or not. But then again lots of doctors like to use the treatment they themselves are most familiar with, because they've had more practice and experience with that, and feel most confident with it. It could be your old endo either sees more young patients or has a seperate protocol for younger patients. Let us know how you go.
