Association of Benign Prostatic Hyperplasia with Male Pattern Baldness

In 1998, a study involving 225 patients with benign prostatic hyperplasia (BPH) and 160 controls investigated the link between BPH and male pattern baldness. The study found that those with BPH had a higher severity of baldness (median grade IV) compared to the control group (median grade III), with a significant difference (P <0.001). Additionally, 53.8% of the BPH group had a baldness grade of IV or higher, compared to 36.9% in the control group (P <0.01), and a higher incidence of inherited baldness was observed in the BPH group (31.6% vs. 12.5% in controls, P <0.001). However, no correlation was found between the severity of baldness and the International Prostate Symptom Score. The study concluded that there is a strong association between BPH and male pattern baldness, which could lead to cross-screening and combined treatment strategies for both conditions.
