The Massachusetts Male Aging Study

The Massachusetts Male Aging Study (MMAS) is a significant research project that began in the late 1980s to understand the health, sexuality, and aging of men. It examined various aspects of men's health, including hormone levels, sexual function, and psychological well-being. By studying a diverse group of men aged 40 to 70, researchers aimed to identify common health issues, particularly related to aging and erectile dysfunction. The findings have provided valuable insights into the physical and emotional changes men experience as they age, contributing to better medical care and understanding of male health issues.
