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.
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.

May 2001 in “Hypertension” This review discusses the potential mechanisms by which androgens may elevate blood pressure, particularly through impacts on the renin-angiotensin system, but reports no new experimental results.

January 2017 in “Archives of biochemistry and biophysics” In this study, testosterone was reported to increase aquaporin levels and water reabsorption in the kidneys of male rats, potentially leading to higher blood pressure, with effects mitigated by flutamide and finasteride.

June 2016 in “PeerJ” In this study, testosterone increased the expression of epithelial sodium channel proteins and mRNAs in rat kidneys, suggesting a potential mechanism for its effect on blood pressure through enhanced sodium reabsorption.
