ABSTRACT
OBJECTIVE: To explore the changes of serum sexual hormone levels in male hyperthyroidisms before and after treatment. METHODS: Compared with the control group, the serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T) and estradiol (E2) of 68 cases of male hyperthyroidisms before and after treatment were detected by chemiluminescence immunoassay technique, and then statistical analysis was performed. RESULTS: The serum T and E2 levels of male hyperthyroidisms were significantly higher than those of the control group before treatment (P < 0.005); while no significant difference in FSH and LH levels existed between the patients and the control group (P > 0.05). There was no difference in FSH, LH, T and E2 levels between patients and the control group after treatment (P > 0.05). CONCLUSION: There are sexual hormone metabolism disorder in hyperthyroidism men, and the increasing serum T and E2 levels are only to adapt the high metabolism environment, and the changes of hypothalamus-pituitary-gonadal axes. Along with the control of hyperthyroidism, the sexual hormone levels return to normal.
