Automated segmentation of whole-body MRI data from the UK Biobank has enabled researchers to quantify prostate volume in 30,616 men, revealing significant insights into age-related prostate enlargement and lower urinary tract symptoms (LUTS). This study highlights that prostate volume increases continuously with age, with notable enlargement occurring in midlife, often exceeding clinical thresholds.

The findings underscore the importance of biological factors such as height, body mass index (BMI), insulin-like growth factor 1 (IGF-1), and bioavailable testosterone as independent correlates of prostate size. Notably, the associations with height and bioavailable testosterone strengthen with advancing age, indicating a potential shift in the biological drivers of prostate enlargement over the life course. Additionally, the study establishes a clear link between larger prostate volumes and higher odds of clinically recorded LUTS, particularly pronounced in midlife, suggesting that age-related changes in prostate size may have significant implications for patient management in geriatric care.

This research provides population-based MRI reference values that can enhance clinical understanding and management of prostate health in aging men. By integrating advanced imaging techniques into routine evaluations, this work sets a precedent for how scalable imaging can inform the assessment of common age-related conditions, potentially guiding future therapeutic strategies and clinical interventions aimed at improving healthspan and quality of life in older populations.
