Can You Shrink or Cure an Enlarged Prostate Naturally?

Question 1: Is There a Natural Way to Shrink an Enlarged Prostate?

Hello John,

Your experience illustrates an important problem with the phrase “natural prostate treatment”: many products are marketed for BPH, but symptom relief, actual prostate shrinkage and prevention of complications are three very different outcomes.

Can Lifestyle Changes Shrink the Prostate?

Not reliably.

Conservative treatment can still be very useful, especially when symptoms are mild or only moderately bothersome. Current European guidance considers watchful waiting and lifestyle measures reasonable for many men with uncomplicated lower urinary tract symptoms.

Useful measures can include:

• reducing excessive evening fluid intake if nocturia is a problem;
• reducing caffeine or alcohol when they clearly worsen urgency or frequency;
• avoiding constipation;
• staying physically active;
• reviewing medicines such as decongestants, antihistamines or diuretics that may worsen urinary symptoms; and
• using relaxed or double voiding when incomplete emptying is mild and your clinician considers it appropriate.

These measures may improve symptoms, but they do not remove obstructing prostate tissue.

Does Saw Palmetto Shrink the Prostate?

The best current evidence does not support that claim.

The U.S. National Center for Complementary and Integrative Health states that enough research has been performed to conclude that saw palmetto is probably not helpful for BPH urinary symptoms.

A 2023 review of 27 studies found that saw palmetto used alone produced little or no benefit for BPH symptoms. NIH-funded trials also failed to show meaningful improvement compared with placebo, even at higher-than-usual doses.

What About Stinging Nettle, Pygeum and Pumpkin Seed?

These products have some limited evidence, but none should be advertised as a reliable cure.

Stinging Nettle

Some studies suggest possible symptom improvement from Urtica dioica, either alone or in combination with other products. However, evidence is limited and preparations vary substantially.

Pygeum

Older short-term studies suggest that pygeum may improve some urinary symptoms, but trials have generally been small, short and based on different preparations.

Pumpkin Seed Products

Certain pumpkin-seed preparations have shown modest improvements in symptom scores in some studies. This does not establish that ordinary pumpkin seeds or pumpkin-seed supplements reliably shrink the prostate or prevent urinary retention.

For more detail, see our evidence-based guide to natural remedies for enlarged prostate.

What About Zinc?

Zinc is an essential nutrient, but taking more zinc does not mean the prostate will shrink.

There is no established role for routine high-dose zinc supplementation as a BPH treatment.

The U.S. National Institutes of Health sets the adult tolerable upper intake level at 40 mg of zinc per day from all sources, unless a clinician has prescribed a higher amount for a specific medical reason.

Excessive long-term zinc intake can contribute to copper deficiency and neurological or immune problems.

Can Kegel Exercises Shrink the Prostate?

No.

Pelvic-floor exercises may help some men improve bladder control, particularly when urinary leakage is present. They do not reduce prostate size or remove bladder-outlet obstruction.

If your main problem is weak flow or incomplete emptying, pelvic-floor exercises should not replace an assessment of urinary flow and residual urine.

What About Valerian to Sleep Through Nocturia?

Valerian does not treat BPH or reduce nighttime urine production.

I would be cautious about using a sedating product simply so you can sleep through an urge to urinate. In older adults especially, sedating medicines and supplements can contribute to dizziness or falls when getting out of bed at night.

If nocturia is a major problem, a 3-day bladder diary is more useful because it can show whether the cause is prostate obstruction, overactive bladder, excessive nighttime urine production, evening fluid intake, sleep apnea or another condition.

What Actually Shrinks an Enlarged Prostate Without Surgery?

The best-established non-surgical prostate-shrinking medicines are 5-alpha-reductase inhibitors:

• finasteride; and
• dutasteride.

These medicines reduce the conversion of testosterone to dihydrotestosterone (DHT), which drives prostate growth.

Current EAU guidance reports that long-term treatment can:

• reduce prostate volume by approximately 18–28%;
• improve symptom scores;
• increase urinary flow; and
• reduce the risk of acute urinary retention and BPH-related surgery.

They are generally most useful in men with moderate-to-severe symptoms and an increased risk of progression, for example a prostate volume above about 40 mL.

They work slowly and may cause reduced libido, erectile dysfunction or ejaculatory problems in some men.

See our BPH medications guide.

What About Alpha Blockers?

Alpha blockers such as tamsulosin, alfuzosin, doxazosin and terazosin can improve urinary flow relatively quickly by relaxing smooth muscle at the prostate and bladder neck.

They do not substantially shrink the prostate or prevent long-term progression by themselves.

If an alpha blocker did not help you previously, I would review why it failed before assuming that every medication will fail. Prostate size, residual urine, bladder function, dose, treatment duration and the actual cause of the symptoms all matter.

If You Decided Against Laser Surgery, Are There Other Procedures?

Yes.

Modern BPH treatment is no longer a choice between “take herbs forever” and “have the entire prostate removed.”

See our BPH procedures and surgery guide.

Question 2: Is There a Permanent Cure for Prostate Enlargement?

The most accurate answer is:

There is no single treatment that guarantees a permanent lifetime cure for every man with BPH.

However, several treatments can provide very durable relief, and some operations remove most or essentially all of the obstructing BPH adenoma without removing the entire prostate.

Radical Prostatectomy Is Not the Standard “Permanent Cure” for BPH

The old answer incorrectly stated that the only permanent cure for BPH is to remove the entire prostate with a radical prostatectomy.

A radical prostatectomy removes the entire prostate, seminal vesicles and some surrounding tissue. It is primarily used to treat prostate cancer.

It is not routinely performed for ordinary benign prostate enlargement.

What Is a Simple Prostatectomy?

A simple prostatectomy is a BPH operation used mainly for very large prostates.

Despite the name, it does not remove the entire prostate. The surgeon removes the enlarged inner adenoma that causes obstruction while leaving the outer prostate capsule in place.

Simple prostatectomy can be performed by open, laparoscopic or robotic approaches depending on the center and patient.

EAU guidance considers open simple prostatectomy effective and durable for very large prostates, although endoscopic enucleation such as HoLEP is often preferred when the necessary expertise and equipment are available because it is less invasive.

Is TURP Only Effective for One or Two Years?

No.

The old answer incorrectly called TURP ineffective because prostate tissue may grow again.

TURP is an established operation with documented long-term symptom and flow improvement. Current EAU guidance describes TURP as the standard surgical procedure for many men with bothersome moderate-to-severe symptoms and prostates roughly 30–80 mL.

Some men eventually require retreatment, but that does not make the original operation ineffective.

Is HoLEP a More Durable Option?

HoLEP removes the obstructing adenoma by separating it from the surgical capsule and morcellating the tissue.

It is highly effective across a broad range of prostate sizes and has very durable results with relatively low retreatment rates.

For very large prostates, HoLEP or another enucleation technique can often accomplish the same BPH objective as simple prostatectomy with a transurethral approach.

What Happened to TUNA?

Transurethral needle ablation (TUNA) is an older thermal technology and is no longer a mainstream modern BPH procedure.

It should not be presented alongside TURP as if both remain equivalent current standards.

Does BPH Become “Enormous” Because a Patient Did Not Take His Pills?

That is too simplistic and can unfairly blame the patient.

BPH progression varies according to:

• age;
• baseline prostate volume;
• PSA as a marker of volume/progression in selected contexts;
• hormonal biology;
• genetics;
• metabolic factors; and
• individual disease course.

Appropriate 5-alpha-reductase inhibitor treatment can reduce progression risk in selected men, but a large prostate is not proof that someone “failed” to take his medication.

When Is Surgery Recommended?

Current AUA guidance recommends surgery particularly when BPH causes:

• kidney insufficiency from obstruction;
• refractory urinary retention;
• recurrent urinary tract infections;
• recurrent bladder stones;
• recurrent visible bleeding attributed to BPH; or
• lower urinary tract symptoms that remain unacceptable despite—or instead of—medical treatment.

Surgery can also be chosen by a well-informed patient who prefers a procedural solution rather than continued medication.

Which Treatments Can Actually Change Prostate Size?

So Can BPH Be “Cured”?

The word cure can be misleading.

For mild BPH, the goal may simply be controlling symptoms safely.

For men with substantial enlargement, medication can shrink the gland and reduce progression risk.

For men with significant obstruction, procedures such as TURP or HoLEP can remove enough tissue to provide many years of relief, sometimes for the remainder of a man’s life.

But no ethical clinician should promise that every BPH treatment will permanently eliminate every urinary symptom forever, because the bladder itself can also change with age and other urinary conditions may develop.
