[Hormonal feature of the androgen status in different-aged males.].

The examined males (n=374) aged from 20 to 69 years were divided into five age groups: the 1st - 20-29 years; the 2nd - 30-39 years; the 3rd - 40-49 years; the 4th - 50-59 years; the 5th - 60-69 years. There was 16,1±7 nmol/l total testosterone level in serum of all aged group. Hormonal signs of androgen deficiency, increased elderly aged groups, were revealed in males of the 2nd group as compared with males of the 1st group. The frequency of androgen deficiency (total testosterone level less than 12,1 nmol/l) in the 1st group was 26,9%; in groups 2, 3 and 4 this index was similar, composed 30,6-33,9%. However, the frequency of androgen deficiency increased and amounted to 44% in the 5th group. The frequency of hypogonadism hormonal signs (total testosterone level less than 8 nmol/l) did not significantly differ in groups 1-4 (6,2-9,3%), and only in group 5 it increased and amounted to 28%. The age-related androgenic deficiency in males was associated with decrease in androgenic function both the gonads, and the adrenal glands, increased level of sex steroid-binding globulin, increased metabolism of testosterone in estradiol and was accompanied by compensatory increase of luteinizing hormone synthesis in the pituitary gland.
