What Causes an Enlarged Prostate?

For many men, an enlarged prostate—also known as benign prostatic hyperplasia (BPH)—becomes a common part of aging. While the exact cause of BPH isn't fully understood, medical research points to hormonal changes as a key factor, particularly as men grow older.

One hormone stands out in this process: dihydrotestosterone (DHT). This potent derivative of testosterone accumulates in the prostate over time and plays a major role in stimulating cell growth. As DHT levels remain high or fluctuate with age, it can prompt the prostate cells to multiply, gradually increasing the gland's size.

Though not harmful in itself, this enlargement can press against the bladder and urethra, leading to familiar symptoms like frequent urination, difficulty starting or maintaining a urine stream, and the feeling of incomplete bladder emptying. These issues often begin around age 50 and become more common with advancing age.

It’s important to note that BPH is not cancer and does not lead to prostate cancer, but it can significantly affect quality of life. Factors like genetics, lifestyle, and overall health may also influence how severely a man is affected, even if DHT remains the central player in the biological process.

While there’s no surefire way to prevent BPH, staying physically active, managing weight, and regular check-ups can help men stay ahead of symptoms. For those experiencing discomfort, a range of treatments—from medications to minimally invasive procedures—can bring meaningful relief.
