February 2023 in “riUfes (Universidade Federal do Espírito Santo)” This study found that supraphysiological doses of testosterone alter endothelial relaxation pathways in hypertensive rats, with varied contributions from nitric oxide, prostanoids, and endothelium-derived hyperpolarizing factors, influenced by estrogen and dihydrotestosterone levels.
October 2013 in “Journal of the American College of Cardiology” This study found that individuals with a nondipper blood pressure pattern had higher 24-hour urinary aldosterone levels, suggesting a possible link to heart issues.
October 2013 in “Journal of the American College of Cardiology” This review discusses the potential role of autonomic dysfunction and sympathetic overactivity in hypertension development and reports no new results; renal denervation therapies have gained popularity for resistant cases.
In this study, testosterone treatment was found to increase blood pressure in rats, potentially through mechanisms involving sodium and water retention in the kidneys and changes in specific gene expressions in the brain.
January 2024 in “Life sciences” This study observed that in spontaneously hypertensive rats, testosterone's effects on endothelium-dependent vasodilation involved reduced nitric oxide levels, increased oxidative stress, and greater reliance on endothelium-dependent hyperpolarization, with variations in these responses noted when testosterone was combined with either anastrozole or finasteride.
