Benign Prostate Hyperplasia

Benign Prostatic Hyperplasia (BPH) is a benign prostate disease based on the benign proliferation of stromal cells and epithelial cells. Due to fibroid hyperplasia and an increase in the glands of the prostate, the entire prostate eventually increases in size [1–4]. In the pathological process of benign prostatic hyperplasia, sex hormones play an important role, the most important of which is the androgen secreted by the testes. Androgen is converted into active dihydrotestosterone (DHT) by type II 5α reductase in the prostate, and DHT also plays an important role in the proliferation of prostate stromal and epithelial cells [5–7].
