Hypothroidism and conception

Women with hypothyroidism find conceiving difficult due to the disturbances of the menstrual cycle and ovulation. Thyroid problems are generally diagnosed by blood tests looking directly at the thyroid hormones. Some women may be diagnosed with Hashimoto’s Disease, which is an autoimmune condition. Hashimoto’s is diagnosed by the presence of thyroid antibodies on blood screening.
