There was executed the clinical examination of 225 women of reproductive age, and in all cases there was made blood sampling for the determination of the serum level of TSH, free T. Observed cases were divided into three groups: 18-29 years, 30-39 years, 40-49 years. As a result, a high prevalence of declined thyroid function was found to be in the form of subclinical manifested hypothyroidism, which exceeds by several times the average incidence of these pathologies in the population. It should be noted that the maximum number of women suffering from subclinical (21.33% of observed cases), and the manifested hypothyroidism (9.33% of the study) was seen in a group of women aged of 18-29 years.
