The study sampling consisted of 96 males from Arkhangelsk and 52 males from village of Nes. The examination was carried out to find out predominant regulative effect of dopamine on the system "hypophysis - thyroid" depending on territory of residence. In males of Zapolyarye, against the background of higher levels of T4, fT3 and TSH and cyclic adenosine mono-phosphate in blood occurs decreasing of levels of thyroglobulin and dopamine in comparison with males of circumpolar territories in case of registration of positive correlation between levels of dopamine and fT3. In males from circumpolar territories age-related decreasing of range of variations of level of dopamine and fT4 under increase of concentration of TSH was registered. At that, negative correlation between content of dopamine and T4 was registered. The age-related dynamics of alteration of level of cyclic adenosine monophosphate with tendency to increase in males of Zapolyarye at the age of 36-60 years in comparison with age group of 22-35 years.
