Sugar, Not Age, Emerges as Key Driver of Men’s Sexual Health Decline
A six-year study presented at ENDO 2025 challenges the view that aging alone governs men’s sexual health. Researchers found that even modest rises in blood sugar, rather than age or testosterone alone, are linked to declines in sperm quality, erectile function, and libido. The findings underscore the importance of metabolic health for men’s sexual vitality in Thailand and beyond.
Traditionally, discussions about declining male sexual and reproductive health have focused on hormones and aging. The new study, led by a senior endocrinologist, suggests that subtle metabolic changes—especially small increases in blood sugar—may play a larger role than previously recognized. “Although age and testosterone have long been linked to changes in sexual health, our findings show these shifts align more closely with modest rises in blood sugar and other metabolic changes,” the lead researcher noted. The takeaway: lifestyle management and regular blood sugar monitoring could help preserve sexual health with age.
