I would certainly avoid the surgery if possible. I went through menopause when I did high dose Cytoxan. The MG just flared up all the time instead. I was so disappointed.

There is plenty of info stating that even post menopausal women who remove the ovaries have increased incidence of dementia and earlier deaths statistically than women who do not. The ovaries secrete small amounts of estrogen even after menopause. Of course there are plenty of women who have to resort to the surgery in cases of cancer or other serious disease. Just think long and hard before you do that for menstrual flare ups.
