Subclinical hypothyroidism and hyperprolactinemia

The authors have studied 25 women aged 22 to 26 years with a diagnosis of prolactinemia moderately increased in primary sterility. Among 25 women under observation, 7 (28%) showed a hormone picture of subclinic hypothyroidism. In fact the evaluation of TSH after stimulation with TRH showed a curve typical of the subclinic hypothyroidism. In 8 women (32%) the authors have found an increase of the thyroid gland, and in 3 patients (12%) galactorrhea. The increase of volume of the thyroid gland was constant in all the women with subclinic hypothyroidism. Considering the results obtained by this study, the authors point out a correlation between subclinic hypothyroidism-hyperprolactinemia and sterility. The data obtained are in accordance with that has been reported in literature.
