Estradiol

17α-estradiol treatment in male mice reduced calorie intake, body mass, and adiposity while improving insulin sensitivity, glucose tolerance, and hepatic insulin responsiveness through estrogen receptor alpha signaling. Benefits were completely abolished in mice lacking estrogen receptor alpha, confirming the mechanism of action.

Review of evidence demonstrating that estradiol at physiological doses enhances endothelium-mediated vasorelaxation, reduces vasoconstriction, and lowers blood pressure in older hypogonadal males. Estrogen receptor alpha mediates these beneficial vascular effects in both sexes.

Continuous estradiol treatment significantly improved cognitive aging trajectory and spatial memory performance in middle-aged to old female rats, with benefits persisting even after treatment cessation. Cognitive improvements were demonstrated to be independent of cardiometabolic health effects, suggesting direct neuroprotective mechanisms.

Estrogen replacement therapy restores sexual hormone levels in women of reproductive age and induces expression of antioxidant and longevity-related genes, suggesting potential anti-aging mechanisms at the molecular level.
