Subclinical hypothyroidism has long been considered as an infertility factor.11 In a particular study, it was observed that the mean duration of infertility was significantly longer in subjects with subclinical hypothyroidism when compared with those who had normal levels of thyroid hormones.2 Similarly, another study observed that women with elevated serum TSH levels had lower pregnancy rate than those with normal circulating levels.11 These findings therefore suggest that subclinical hypothyroidism may have impact on female fertility.
