Did you know that your prostate gland doubles in size between ages 40 and 60? This walnut-sized gland surrounding the urethra produces fluid for semen and plays a role in hormone metabolism. While prostate changes occur naturally with age, distinguishing between normal aging and conditions requiring medical attention determines whether you need enlarged prostate treatment.
Benign prostatic hyperplasia (BPH) affects many men as they age, causing the prostate to compress the urethra and obstruct urine flow. Unlike prostate cancer, BPH doesn’t spread to other tissues, but untreated symptoms can lead to bladder damage, kidney problems, and urinary tract infections.

Prostate Changes After 40
The prostate grows through two main phases: during puberty when it doubles in size, and again starting around age 25, continuing throughout life. This second growth phase accelerates after 40 due to hormonal changes, particularly the conversion of testosterone to dihydrotestosterone (DHT) within prostate cells.
Prostate tissue consists of glandular cells that produce prostatic fluid and smooth muscle cells that help expel semen during ejaculation. As men age, both cell types multiply, but the proportion changes – more smooth muscle develops relative to glandular tissue, contributing to urinary symptoms. The transitional zone, which surrounds the urethra directly, experiences the most growth in BPH, explaining why even modest enlargement can cause significant symptoms.
Prostate volume typically increases with age. However, prostate size doesn’t always correlate with symptom severity – some men with larger prostates experience minimal symptoms, while others with modest enlargement face significant urinary difficulties. The shape and direction of growth matter more than absolute size.
Recognizing BPH Symptoms
Lower urinary tract symptoms from BPH fall into two categories:
– Storage symptoms include frequent urination (more than eight times daily), nocturia (waking multiple times at night to urinate), sudden urges to urinate, and occasional urge incontinence
– Voiding symptoms encompass weak urine stream, difficulty starting urination, intermittent flow, straining to urinate, and feeling of incomplete bladder emptying
Symptom progression typically follows a predictable pattern. Initially, men notice taking longer to empty their bladder or needing to wake once nightly to urinate. As obstruction increases, the bladder muscle thickens to overcome resistance, leading to more frequent contractions and reduced capacity. Eventually, the bladder may lose its ability to contract effectively, resulting in urinary retention.
The International Prostate Symptom Score (IPSS) quantifies symptom severity through seven questions about urinary habits, with scores ranging from 0-35:
– Mild symptoms (0-7) might require only monitoring
– Moderate symptoms (8-19) often benefit from medication
– Severe symptoms (20-35) may require procedural intervention
Quality of life assessment adds another dimension, measuring how much symptoms interfere with daily activities, work, and sleep.
PSA Testing and Screening Guidelines
Prostate-specific antigen (PSA) testing measures a protein produced exclusively by prostate cells, with normal levels typically below 4.0 ng/mL. However, PSA rises with any prostate enlargement – whether from BPH, prostatitis, or cancer – making interpretation complex. Age-adjusted ranges provide better context:
– Under 2.5 ng/mL for men 40-49
– Under 3.5 ng/mL for 50-59
– Under 4.5 ng/mL for 60-69
– Under 6.5 ng/mL for men over 70
PSA velocity, measuring how quickly levels change over time, offers additional diagnostic value. Annual increases exceeding 0.75 ng/mL may indicate cancer even when absolute values remain within normal ranges. Free PSA percentage helps distinguish between BPH and cancer – higher percentages of unbound PSA suggest benign enlargement, while lower percentages warrant further investigation.
Singapore’s Ministry of Health recommends discussing PSA screening with men aged 50-75 who have sufficient life expectancy. Men with family history of prostate cancer or BRCA gene mutations should consider screening from age 45. Digital rectal examination (DRE) complements PSA testing by detecting nodules, asymmetry, or textural changes that might indicate cancer despite normal PSA levels.
Enlarged Prostate Treatment Options
Medical management begins with alpha-blockers like tamsulosin or alfuzosin, which relax smooth muscle in the prostate and bladder neck, improving urine flow within days to weeks. These medications work regardless of prostate size, making them suitable for men with bothersome symptoms but modest enlargement. Common side effects include dizziness, retrograde ejaculation, and nasal congestion.
5-alpha-reductase inhibitors such as finasteride or dutasteride block DHT production, shrinking the prostate over 3-6 months. These medications work better for larger prostates and reduce progression risk, including acute urinary retention and need for surgery. Combination therapy using both drug classes provides effective symptom relief for men with moderate to severe symptoms and enlarged prostates.
Minimally invasive procedures offer alternatives when medications prove insufficient. Transurethral resection of the prostate (TURP) remains a standard approach, removing obstructing tissue through the urethra. Other options include laser therapies (HoLEP, GreenLight), which vaporize excess tissue with less bleeding risk, and UroLift, which uses implants to hold prostate lobes apart without tissue removal. Prostatic artery embolization blocks blood flow to shrink the gland, preserving sexual function better than surgical options.
Lifestyle Modifications for Prostate Health
Dietary changes can reduce BPH symptoms and slow progression:
– Limiting evening fluid intake reduces nocturia
– Avoiding caffeine and alcohol decreases bladder irritation and urgency
– Double voiding – urinating, waiting several minutes, then trying again – helps empty the bladder more completely
– Scheduled voiding every 3-4 hours prevents overdistension that can worsen symptoms
Exercise improves prostate health through multiple mechanisms:
– Aerobic activity reduces inflammation markers linked to prostate growth
– Pelvic floor exercises strengthen muscles supporting bladder control
– Resistance training helps maintain healthy testosterone levels and body composition
– Regular exercise is associated with fewer urinary symptoms and slower BPH progression
Weight management particularly benefits prostate health, as abdominal obesity increases estrogen production and inflammatory cytokines that stimulate prostate growth. Even modest weight loss can improve urinary symptoms and reduce medication requirements. Mediterranean-style diets rich in vegetables, fish, and healthy fats show associations with reduced BPH risk and symptom severity.
What Our Urologist Says
Clinical experience shows men often wait years before seeking help for urinary symptoms, assuming they’re normal aging. However, earlier intervention typically means simpler treatment options and improved outcomes. Enlarged prostate treatment has evolved significantly – we can now offer procedures that preserve sexual function while treating symptoms.
Many patients worry that prostate treatment will affect sexual performance, but current medications and procedures minimize these risks. Alpha-blockers may cause retrograde ejaculation but don’t affect erection quality or libido. Surgical techniques like UroLift and Rezum preserve ejaculatory function in many men.
The relationship between BPH and prostate cancer remains a common concern. Having BPH doesn’t increase cancer risk, though both conditions can coexist. Regular monitoring allows us to detect any concerning changes early while managing bothersome symptoms.
Conclusion
Early detection through regular screening allows for simpler treatment options and better outcomes. Men with moderate to severe symptoms have multiple effective treatments available, from medications to minimally invasive procedures that preserve sexual function.
If you’re experiencing frequent nighttime urination, weak urine stream, or difficulty starting urination, a MOH-accredited urologist can provide comprehensive evaluation and enlarged prostate treatment options tailored to your specific condition.
