CONTEXT: Androgen deprivation therapy (ADT) for prostate cancer (PCa) leads to a selective loss of leg muscle function during walking. Rodent models of ADT have demonstrated that the levator ani is exquisitely androgen sensitive. OBJECTIVE: To determine whether the high androgen responsiveness of the levator ani muscle documented in rodents is evolutionarily conserved and ADT is associated with a selective loss in leg muscle volume. DESIGN: Prospective longitudinal case-control study. SETTING: Tertiary referral hospital. PARTICIPANTS: Thirty-four men newly beginning ADT and 29 age-matched controls with PCa. MAIN OUTCOME MEASURES: The muscle volumes in liters of the levator ani and primary mu..
