Little is known about the relationship between blood pressure and endogenous sex steroid hormones in patients with essential hypertension. Studies in hypertensive men have described decreased androgens. Men with cardiovascular disease may have estrogen levels which are increased or similar to healthy controls. We measured selected sex steroid hormones in 24 medication-free patients with uncomplicated essential hypertension (diastolic blood pressure less than or equal to 90 mmHg) and 24 normotensive subjects. The groups were equally divided by race, gender, age and weight. Hypertensive men had lower levels of both free and total testosterone and androstenedione than controls. The converse was true for hypertensive women. Androgen levels were similar in blacks and whites regardless of gender or blood pressure. Estradiol levels were higher in hypertensive men and women than controls and in blacks than whites. Levels of luteinizing hormone and sex hormone binding globulin were similar in all subjects. The clinical and pathophysiological significance of our findings merits further investigation.

The effect of an angiotensin-converting enzyme inhibitor, lisinopril, on gonadal hormones was assessed in 20 patients with essential hypertension. A daily dose of 5 to 20 mg of lisinopril was administered for 6 mo. In male patients, the free testosterone (f-T) concentration decreased significantly (before, 13.8+/-2.4 pg/ml; after, 9.9+/-1.5 pg/ml: mean +/- SEM, p < 0.05), whereas the plasma total testosterone (T), estradiol (E2), and sex hormone binding globulin (SHBG) concentrations were not significantly affected. Lisinopril had no effect on plasma T, f-T, or E2 concentrations in female patients, but significantly increased the plasma SHBG concentration (before, 48.0 6.1 nmol/l; after, 62.7+/-6.7 nmol/l: p < 0.01). The results of this preliminary study suggest that lisinopril affects plasma f-T and SHBG concentrations. The clinical implications of lisinopril-induced changes in plasma f-T and SHBG concentrations remain to be clarified.
