At What Age Does the Prostate Start to Grow?

The prostate naturally begins to grow around age 40, though symptoms usually appear later. Understanding this process helps you know when it’s worth starting to monitor your prostate health.

After 40, hormonal changes cause the prostate to slowly increase in size. This is normal: not every man will develop symptoms, but most will experience some degree of growth over the years.

Urinary symptoms become common after age 50. About half of men by 60, and the large majority by their 80s, have some degree of benign hyperplasia. The speed and intensity vary widely from one person to another.

The general recommendation is to start prostate check-ups at age 50, or at 40 if you have a family history of prostate cancer or prostate problems. These check-ups not only monitor benign growth — they also enable the early detection of other conditions.

Prostate growth cannot be fully prevented, but maintaining a healthy weight, exercising and managing conditions such as diabetes help keep symptoms milder. Regular check-ups are the best tool for catching any change early.
