Thyroid function in girls with menstrual disturbances in iodine-deficiency region

The estimate the functional state of the female adolescent thyroid with menstrual cycle disorder, living in the iodine deficiency regions, 130 female adolescents with irregular menstrual cycle were examined. Hypothyroidism incidence (in them) was 16.9%. In addition we considered TSH range 2.5–4.0 mU/l (highly normal TSH level) the extent of which was 12.3%. High extent of antibody carriage to the thyroid (31.3%) in girls with irregular menses, having high blood TSH level. There were no statistical differences between the structure of menstrual dysfunction and menstrual duration depending on thyroid function (p = 0.2383, respectively), as well as the average values of estradiol levels depending on TSH level (p = 0.3213). Thus, the influence of highly normal TSH on menstrual function development in female adolescents.
