AR and benign prostatic hyperplasia: Benign prostatic hyperplasia (BPH), which is commonly associated with lower urinary tract symptoms (LUTS), is a highly prevalent disease that is characterized by the proliferation of the human prostate and greatly affects the quality of life of ageing men.1 The prostate is a hormone‐responsive organ, and androgen receptor (AR) signalling plays a fundamental role in BPH progression.
