Not just diabetes: How slightly high blood sugar wrecks men’s sexual health

Aging men aren't just battling time—they're up against rising blood sugar. New research reveals that subtle increases in metabolic markers like glucose have more influence on declining sexual health than age or testosterone levels alone. The findings, based on a 6-year study of otherwise healthy men, show that even below-diabetes-level sugar changes can impair sperm mobility and erectile function. But there’s good news: lifestyle choices and medical support could help men maintain reproductive vitality well into older age.
