Prostate Health: What Every Man Should Understand About This Gland

What Is the Prostate and What Does It Do?

The prostate is a small, walnut-sized gland located just below the bladder and in front of the rectum. It surrounds the urethra — the tube through which urine and semen leave the body — which is why prostate problems frequently affect urinary function.

Its primary role is reproductive: the prostate produces a fluid that forms part of semen, helping to nourish and transport sperm. Although it is not essential for life, its anatomical position means that changes to its size or health can have significant effects on urinary and sexual function.

How the Prostate Changes With Age

The prostate goes through two main growth phases during a man's life. The first occurs during puberty, when testosterone drives initial development. The second begins around age 25 and continues slowly throughout life — a process that becomes clinically relevant for most men after age 50.

This gradual growth is largely driven by hormonal changes, particularly shifts in the balance between testosterone and estrogen. As the gland enlarges, it can begin to press on the urethra, leading to the urinary symptoms many older men experience. This age-related growth is not inherently dangerous but does require attention when symptoms arise.

Common Prostate Conditions

Three conditions account for the vast majority of prostate health concerns in men:

• Prostatitis: Inflammation of the prostate, sometimes caused by bacterial infection. It can cause pelvic pain, painful urination, and flu-like symptoms. It most commonly affects men under 50 and is treatable, though some forms are chronic.
• Benign Prostatic Hyperplasia (BPH): Non-cancerous enlargement of the prostate that becomes increasingly common after age 50. Symptoms include a weak urine stream, frequent nighttime urination, and difficulty starting or stopping urination. Learn more in our article on BPH and when symptoms need medical review.
• Prostate cancer: The most common cancer diagnosed in American men. Many cases are slow-growing, but the disease varies widely in aggressiveness. Early-stage prostate cancer often produces no symptoms, making screening conversations particularly important.

Symptoms You Should Not Ignore

Prostate conditions share overlapping symptoms, which is why self-diagnosis is unreliable. The following changes in urinary or sexual function warrant a visit to a healthcare provider:

• Difficulty starting urination or maintaining a steady stream
• Frequent urge to urinate, especially at night
• Feeling that the bladder has not fully emptied
• Blood in urine or semen
• Pelvic, lower back, or hip pain that does not resolve
• Painful ejaculation or decreased urine flow

None of these symptoms confirm a specific diagnosis — only a clinician can evaluate what is causing them. That said, persistent changes to urinary function are among the most actionable early signals men can respond to.

Prostate Screening: What to Expect

Prostate screening typically involves two approaches used together: a PSA blood test and, in some cases, a digital rectal exam (DRE). Neither is infallible on its own, which is why clinical context — including age, family history, and race — shapes how results are interpreted.

Screening guidelines vary between major medical organizations, and recommendations are not one-size-fits-all. Men at higher risk — including Black men and those with a first-degree relative who had prostate cancer — are generally advised to start the conversation with their doctor earlier.

Lifestyle Factors and Prostate Health

Research suggests a meaningful connection between general lifestyle habits and prostate health outcomes over time. While no diet or exercise routine has been proven to prevent prostate conditions outright, several patterns are associated with lower risk in observational studies:

• Physical activity: Regular exercise is linked to better urinary function and may reduce the risk of aggressive prostate cancer, according to some research.
• Dietary patterns: Diets high in vegetables — particularly tomatoes, cruciferous vegetables, and legumes — appear in observational data to be associated with prostate health benefits.
• Weight management: Obesity has been associated with an increased risk of more aggressive forms of prostate cancer.

These habits support broader health goals regardless of their specific effect on the prostate. The Men's Preventive Care hub offers practical guidance on screenings and healthy habits across every stage of adult life.
