MedPageToday -- Interest and involvement in sex remain strong among many men as they age -- even into their 90s, an Australian cohort study found. Among 2,783 men ages 75 to 95, 48.8% (95% CI 47 to 50.6) felt that sex was still at least somewhat important in their life, according to Zoë Hyde, MPH, of the University of Western Australia in Crawley, and colleagues.
