"pay attention and you be the judge. but cut the meds, not the iodine."
I tend to agree with Trapper. When it comes to the original question at this post, I will say; no, I dont believe Iodine made you premenopausal. It has no FSH destroying effect as I know of; rather the oposite. I ovulate still, pretty regular: two months before my 50ies, 5 years into iodine.
