Prostate Physiology & the Dynamics of Testosterone Metabolism

The prostate gland is a fibromuscular and glandular organ encircling the proximal portion of the male urethra. Its primary physiological function is the production of seminal fluid, which nourishes and transports sperm cells. With advancing age, circulating testosterone is locally converted into dihydrotestosterone (DHT) through the action of the enzyme 5-alpha-reductase. DHT exhibits significantly higher binding affinity for androgen receptors within stromal cells of the prostate.

This biological mechanism contributes to progressive cell proliferation within the transitional zone of the prostate gland (benign prostatic hyperplasia, BPH). As tissue volume expands, mechanical compression on the prostatic urethra may produce characteristic Lower Urinary Tract Symptoms (LUTS):

• Hesitancy before the onset of urination.
• Weakened or interrupted urinary stream.
• Need for abdominal straining to achieve bladder evacuation.
• Post-void residual fullness sensation.

Adopting evidence-based preventive measures — consistent aerobic physical activity, weight management, and a diet rich in plant sterols — helps moderate symptom progression and supports lasting quality of life.

Clinical Guide: Male Pelvic Floor Functional Kinesiology

The pelvic floor musculature (including the levator ani, bulbospongiosus, and ischiocavernosus muscles) forms a dynamic supportive hammock beneath the urinary bladder and rectum. In men, these muscles play an indispensable role in maintaining urinary continence and stabilizing the pelvis during locomotion.
