Subclinical hypothyroidism treatment 2012 honda: The association between subclinical hypothyroidism and erectile dysfunction

The elevation of TSH levels reflects the sensitivity of the hypothalamic-pituitary axis to small decreases in circulating thyroid hormone; as the thyroid gland fails, the TSH level may rise above the upper limit of normal when the free T 4 level has fallen only slightly and is still within the normal range.
