Metabolic well being components, together with small will increase in blood sugar, are the principle drivers of change within the reproductive methods and sexual functioning of ageing males, based on a examine being introduced Saturday at ENDO 2025, the Endocrine Society’s annual assembly in San Francisco, Calif.
“Although age and testosterone levels have long been considered an impetus for men’s declining sexual health, our research indicates that these changes more closely correlate with modest increases in blood sugar and other metabolic changes,” mentioned Michael Zitzmann, M.D., Ph.D., professor and physician of drugs at College Hospital in Muenster, Germany. “This means that men can take steps to preserve or revive their reproductive health with lifestyle choices and appropriate medical interventions.”
These conclusions observe a long-term examine of wholesome males (with out diabetes mellitus, coronary heart illness and/or most cancers) aged 18–85 that started in 2014 with 200 members and concluded in 2020 with 117 members. Researchers studied progressive adjustments in members’ semen and hormonal profiles, erectile functioning and metabolic well being (BMI and blood sugar ranges marked by the HbA1c take a look at).
Findings indicated that over time hormone ranges and semen parameters stayed largely inside regular ranges. Nonetheless, sperm motion and erectile operate declined in males with minimally elevated blood sugar ranges that had been under the 6.5% HbA1c diabetes threshold. The examine additionally discovered that whereas testosterone ranges didn’t have a direct affect on erectile operate, they did correlate with members’ libido evaluation.
“We’re hopeful that the information gleaned from this study will help doctors and their patients formulate effective male sexual health maintenance plans,” Zitzmann added. “We now know that it’s in our power to retain sexual and reproductive well-being in men, even as they age.”
This analysis was performed as a part of the FAME 2.0 examine.
