Risk Factors for Benign Prostatic Hyperplasia (BPH)

Non-Modifiable Risk Factors

Age is a significant risk factor for BPH, with prevalence increasing from 40-45 years, reaching 60% by age 60, and 80% by age 80, according to The Journal of Urology 1, 2
Hormonal factors, including the conversion of testosterone to dihydrotestosterone (DHT), play a role in BPH development, as reported by The Journal of Urology 1, 2

BPH develops due to an imbalance between cellular growth and apoptosis in favor of growth, causing increased cellular mass in the prostatic transition zone, as described by The Journal of Urology 1, 2
BPH can lead to benign prostatic enlargement (BPE), which can cause obstruction at the level of the bladder neck, termed benign prostatic obstruction (BPO), according to The Journal of Urology 1, 2
BPH contributes to LUTS via two primary mechanisms: direct obstruction from enlarged tissue and increased smooth muscle tone and resistance, as reported by The Journal of Urology and Praxis Medical Insights 1, 3

The prevalence of moderate-to-severe LUTS rises to nearly 50% by age 80, with increasing risk of complications such as acute urinary retention, as reported by The Journal of Urology 1, 4
Regular monitoring is recommended for men with risk factors for BPH progression, according to The Journal of Urology 1, 4

The American Urological Association recognizes inflammation as an important factor in BPH etiology 5
