title: Estradiol and nitric oxide in men over 50 years of age.
abstract: We measured the circulatory levels of nitric oxide and estradiol in men over 50 years with estrogenisation findings. We investigated relation between nitric oxide, which is the principal signal for relaxation of vascular smooth muscle cells, and estradiol levels in serum in men over 50 years with estrogenisation. This study included 14 men with (group 1) and 20 without estrogenisation findings (group 2). Mean nitric oxide and estradiol levels were found to be significantly lower in group 2 than group 1. Group 2 had lower levels sex-hormone binding globin and higher both systolic and diastolic blood pressure values than group 1. There was a significant correlation between nitric oxide and estradiol in esrogenisation group.
