Serum sex hormones and the 20-year risk of lower urinary tract symptoms in community-dwelling older men.

Objective: To evaluate serum sex steroid hormone concentrations and long-term risk of subsequent lower urinary tract symptoms (LUTS) in a cohort of community-dwelling older men.

Subjects And Methods: Between 1984 and 1987, serum sex hormone concentrations were measured in participants in the Rancho Bernardo Study, a prospective, community-based study. In 2006, the American Urological Association Symptom Index (AUA-SI) was mailed to surviving male participants.
