Cetrorelix Pamoate (AEZS-102) in Patients With Symptomatic BPH: a Double-blind Placebo-controlled Efficacy Study

Benign Prostatic Hypertrophy (BPH) is a common and bothersome condition of aging men. It is characterized by an enlargement of the prostate occurring in human male over the age of 50 which increases in prevalence with age, and among those aged 50 to 80, about 40% report moderate or severe urinary symptoms of prostatism.
