Vaginal aging: from concealed symptoms to defined biomarkers (opens in new tab)

Vaginal aging is a multifactorial biological process characterized by structural, functional, and molecular alterations driven primarily by estrogen decline. This review summarizes current evidence on potential biomarkers across five domains: physiological parameters, imaging features, histological changes, and molecular alterations. We further discuss methodological challenges and future research directions necessary to establish standardized and clinically applicable biomarkers. Understandi...
