- Hearing loss is a common age-related condition that affects quality of life. Testosterone may help protect against hearing loss.
- This study examined the association between serum testosterone and hearing loss in older Japanese men (aged 60–69).
- Higher serum testosterone levels were associated with lower odds of high-frequency (4 kHz) hearing loss.
These findings were published in Otol Neurotol (2025;46(8):e342-e348)
