For something the size of a walnut, the prostate gland plays a massive role in a man’s life. Yet, most men don’t think about it until it starts causing problems. Whether you’re here for a health check-in or just curious about how your body works, understanding the prostate is a vital part of men’s wellness.
The prostate is a small, muscular gland found only in biological males. It sits deep in the pelvis, tucked directly below the bladder and in front of the rectum.
Its most unique physical feature is its location: it wraps entirely around the urethra—the “pipe” that carries both urine and semen out of the body. This “donut-hole” placement is exactly why prostate issues often lead to bathroom troubles.
What Does the Prostate Actually Do?
The prostate isn’t just a passive neighbor to your bladder; it’s a busy factory and a mechanical switch. Its main functions include:
- Supporting Fertility (The “Semen Factory”)
The prostate’s primary job is to produce prostatic fluid. This milky liquid makes up about 30% of the volume of semen. It’s packed with enzymes (like PSA), zinc, and citric acid that:
- Nourish sperm: Providing the energy they need to swim.
- Neutralize acidity: The female reproductive tract is naturally acidic; the alkaline prostatic fluid acts as a shield, helping sperm survive long enough to reach an egg.
- The Ejaculation Pump
The prostate contains smooth muscle fibers. During orgasm, these muscles contract quickly and powerfully, “pumping” the seminal fluid into the urethra to be expelled. - The Traffic Controller
The prostate acts as a biological switch. During sexual activity, it closes off the opening to the bladder. This ensures that semen goes out the right way and prevents urine from mixing into the ejaculate. - Hormone Conversion
The prostate helps convert testosterone into a more active form called DHT (dihydrotestosterone), which is essential for male physical characteristics and sexual health.
Why the Prostate Changes with Age
Unlike most organs that stop growing after puberty, the prostate often experiences a second growth spurt later in life.
- In your 20s: It’s about the size of a walnut.
- In your 50s and beyond: It can grow to the size of a lemon or even an orange.
This growth is known as BPH (Benign Prostatic Hyperplasia). Because the gland surrounds the urethra, as it gets bigger, it “squeezes” the tube. This is why many men notice a weaker urine stream or the need to wake up multiple times at night as they get older.
Tips for a Healthy Prostate
While you can’t stop time, you can support your prostate health through lifestyle choices: - Eat Your “Red” Veggies: Lycopene, found in cooked tomatoes and watermelon, is linked to better prostate health.
- Stay Active: Regular exercise helps maintain healthy hormone levels and reduces inflammation.
- Know Your Numbers: Starting at age 50 (or 45 if you have a family history), talk to your doctor about a PSA test to screen for early signs of trouble.
