Does Hashimoto’s disease affect fertility?

Hashimoto’s disease, also called Hashimoto’s thyroiditis, is an autoimmune condition in which the immune system makes antibodies against the thyroid gland. The thyroid becomes inflamed. Initially the person may release extra thyroid hormone, but over time most people are left with an underactive thyroid gland (hypothyroidism). Untreated hypothyroidism in women can make it harder for them to conceive.
