Quick Answer
Every BPH treatment has tradeoffs. Alpha blockers can cause dizziness and ejaculation problems; finasteride or dutasteride can affect libido, erections and ejaculation; tadalafil can cause headache, flushing and low blood pressure in susceptible patients. Procedures may cause temporary burning, urgency, blood in the urine or catheter dependence, while tissue-removing surgery can also cause bleeding, urethral scar tissue, temporary incontinence and very commonly dry or retrograde ejaculation.
The most important point is that erectile dysfunction, ejaculation changes, urinary leakage, bleeding and retreatment risk are not the same for every treatment. A less invasive procedure may preserve ejaculation better but offer less symptom improvement or a higher chance of future retreatment. A more definitive operation such as TURP or HoLEP usually provides stronger, more durable relief but is more likely to change ejaculation.
Side effects should be discussed before treatment so the option fits your urinary symptoms, prostate anatomy, health, medications and sexual priorities.
BPH treatment is no longer simply a choice between “medicine or surgery.” Modern care includes watchful waiting, several medication classes, ejaculation-preserving minimally invasive procedures and highly durable operations such as TURP and HoLEP.
That makes treatment more individualized—but it also makes side-effect counseling more important.
The 2026 AUA procedural guideline specifically emphasizes balancing effectiveness, durability, procedure-specific adverse effects, sexual function and retreatment risk when choosing a BPH procedure.

BPH Treatment Side Effects at a Glance
| Treatment | Common / Important Side Effects | Sexual Effect | Retreatment / Durability |
|---|---|---|---|
| Alpha blockers | Dizziness, orthostatic hypotension, fatigue; cataract-surgery IFIS risk | Ejaculatory dysfunction, especially tamsulosin/silodosin | Symptoms return if medicine is stopped; does not prevent progression |
| Finasteride / dutasteride | Slow onset; breast tenderness/enlargement in a small minority | Reduced libido, ED, lower semen volume/ejaculatory dysfunction | Disease-modifying in enlarged glands; works only while taken |
| Tadalafil 5 mg daily | Headache, flushing, dyspepsia, nasal congestion, back/muscle pain; hypotension risk | Often improves erections | Controls symptoms; does not prevent BPH progression |
| UroLift / PUL | Temporary burning, urgency, pelvic discomfort, hematuria | Ejaculation usually preserved | Higher retreatment risk than TURP |
| Rezūm | Temporary urgency, dysuria, hematuria, swelling and catheter need | Erections/ejaculation usually preserved | 5-year surgical retreatment about 4.4% in pivotal data |
| Aquablation | Bleeding, temporary urinary symptoms, catheterization | Lower anejaculation rate than TURP in trials | Good 5-year durability; some retreatment risk |
| PAE | Pelvic discomfort, urinary symptoms, retention; rare non-target embolization | Often relatively favorable | Higher retreatment than TURP/enucleation |
| TURP | Bleeding, infection, retention, temporary urgency/incontinence, urethral stricture/bladder-neck contracture | Dry/retrograde ejaculation common; ED possible but less common | Durable |
| HoLEP | Temporary stress leakage, urgency, dysuria, bleeding; stricture uncommon | Dry/retrograde ejaculation very common; erectile function usually preserved | Very durable, low retreatment |
| Simple prostatectomy | More invasive surgery: bleeding, catheter, infection, temporary urinary leakage | Ejaculatory change expected; erectile effects possible | Very durable; used mainly for selected very large glands |
Do Not Ask Only “Will This Cause Impotence?”
Ask separately about erections, ejaculation, orgasm, urinary control, catheter time, bleeding, recovery and retreatment. A procedure can preserve erections while still causing permanent dry ejaculation.
Side Effects of BPH Medications
Alpha Blockers
Common alpha blockers include tamsulosin, alfuzosin, silodosin, doxazosin and terazosin.
Possible side effects include:
- dizziness;
- lightheadedness when standing;
- low blood pressure;
- fatigue;
- nasal congestion;
- and ejaculatory dysfunction.
EAU notes that ejaculatory dysfunction occurs more often with the more selective drugs, especially tamsulosin and silodosin. Vascular adverse effects are more prominent with less uroselective agents such as doxazosin and terazosin.
Alpha blockers are also associated with intraoperative floppy iris syndrome (IFIS). Tell an ophthalmologist before cataract surgery if you currently take—or previously took—an alpha blocker.
Finasteride and Dutasteride
5-alpha-reductase inhibitors are useful in appropriately enlarged prostates because they can shrink the gland and reduce long-term progression risk.
Their most relevant adverse effects are sexual:
- reduced libido;
- erectile dysfunction;
- reduced semen volume;
- ejaculatory dysfunction;
- and, less commonly, breast tenderness or enlargement.
EAU reports gynecomastia/breast or nipple tenderness in roughly 1–2% of treated men.
Finasteride and dutasteride also lower PSA by approximately 50% after several months. This is not an “adverse effect,” but it is clinically important because PSA must be interpreted using a new baseline.
Mood Symptoms
Mood-related safety warnings have received increased regulatory attention. A patient taking finasteride who develops depressed mood, depression or suicidal thoughts should seek medical advice promptly rather than stopping or continuing treatment without discussion.
Tadalafil 5 mg Daily
Tadalafil can improve LUTS and erectile function. Common adverse effects can include:
- headache;
- flushing;
- indigestion;
- nasal congestion;
- back or muscle pain;
- and lightheadedness.
Tadalafil must not be used with nitrates because the combination can cause dangerous hypotension. It is also unsuitable in several unstable or recent cardiovascular conditions.
Antimuscarinics
These may be used for urgency/frequency-dominant symptoms in selected men.
Common adverse effects include:
- dry mouth;
- constipation;
- blurred vision;
- and possible worsening of bladder emptying.
They require more caution when PVR is already high or retention risk is significant.
Beta-3 Agonists
Mirabegron and related drugs can help storage symptoms such as urgency and frequency.
Possible adverse effects include:
- increased blood pressure;
- headache;
- urinary infection;
- and, uncommonly, urinary retention.
Side Effects of Minimally Invasive BPH Procedures
UroLift / Prostatic Urethral Lift
PUL places small implants that hold obstructing prostate tissue away from the urethra.
Common early effects are usually temporary:
- burning with urination;
- urgency/frequency;
- pelvic discomfort;
- blood in urine;
- and occasionally temporary catheter use.
Its major advantage is a low incidence of sexual side effects, particularly preservation of ejaculation.
The tradeoff is durability: EAU states symptom and flow improvements are inferior to TURP at 24 months and retreatment is more common.
Rezūm / Water-Vapor Thermal Therapy
Rezūm deliberately causes tissue inflammation and necrosis, so symptoms can temporarily worsen before they improve.
Short-term effects can include:
- burning;
- urgency;
- frequency;
- blood in urine;
- pelvic discomfort;
- temporary retention;
- and catheter dependence for several days in some men.
Sexual function is generally well preserved. EAU cites 98% preservation of antegrade ejaculation at 12 months in one comparative study, while five-year pivotal-trial surgical retreatment was 4.4%.
Aquablation
Aquablation uses an image-guided robotic waterjet to remove tissue.
The most important early concern is bleeding, although modern hemostasis techniques have improved safety.
Other short-term effects include catheterization, urinary burning, urgency and transient leakage.
In the WATER randomized trial, persistent early adverse events were lower with Aquablation than TURP, and among sexually active men the anejaculation rate was 10% with Aquablation versus 36% with TURP. EAU also reports 81–90% preservation of antegrade ejaculation in long-term WATER/WATER II data.
Prostate Artery Embolization (PAE)
PAE is performed by an interventional radiologist and avoids transurethral resection.
Possible adverse effects include:
- pelvic/perineal discomfort;
- temporary urinary irritation;
- urinary retention;
- groin/wrist access-site complications;
- contrast/radiation exposure;
- and rare non-target embolization.
The sexual profile can be favorable, but EAU emphasizes that evidence is mixed. More importantly, retreatment is substantially more common than after TURP or enucleation. In one five-year randomized study cited by EAU, 42% of men initially treated with PAE ultimately underwent TURP.
Side Effects of TURP, HoLEP and Other BPH Surgery
TURP
TURP remains a reference surgical treatment, especially for moderate-sized prostates.
Potential early complications include:
- bleeding and blood clots;
- urinary infection;
- temporary catheter dependence;
- urinary urgency/frequency;
- painful urination;
- temporary leakage;
- and urinary retention.
Potential later complications include:
- urethral stricture;
- bladder-neck contracture;
- persistent urinary incontinence in a minority;
- erectile dysfunction in some men;
- and retrograde/dry ejaculation.
Bipolar TURP has similar efficacy to monopolar TURP with an improved perioperative safety profile and avoids classic TUR syndrome from hypotonic irrigation fluid.
HoLEP
HoLEP is highly effective and durable across prostate sizes.
Short-term effects can include:
- burning and frequency;
- blood in urine;
- temporary stress urinary leakage;
- urgency;
- and catheter-related discomfort.
Most temporary urinary leakage improves as the sphincter and pelvic floor recover, although persistent incontinence can occur in a minority.
The most predictable sexual change is dry/retrograde ejaculation. Erectile function, however, is usually preserved, and comparative evidence does not show worse erectile outcomes than TURP.
TUIP
TUIP makes one or more incisions at the bladder neck/prostate rather than removing large amounts of tissue. It is mainly suitable for smaller prostates without a significant middle lobe.
Compared with TURP, bleeding risk is low and retrograde ejaculation is generally less common, but reoperation is more frequent.
Simple Prostatectomy
Open or robotic simple prostatectomy is used mainly for selected very large glands.
Because it is more invasive, potential complications include:
- greater blood loss;
- infection;
- longer catheterization;
- temporary urinary leakage;
- thromboembolic/anesthetic complications;
- and ejaculatory changes.
Simple Prostatectomy Is Not Radical Prostatectomy
BPH surgery removes the obstructing adenoma while leaving the prostate capsule. Radical prostatectomy removes the prostate for cancer and has a different side-effect profile.
Sexual Side Effects: Erection, Ejaculation and Orgasm Are Different
Erectile Function
Ability to achieve and maintain an erection. Many BPH procedures preserve erections even when ejaculation changes.
Ejaculation
Release of semen. TURP and HoLEP frequently cause dry/retrograde ejaculation, while UroLift, Rezūm and Aquablation generally preserve it more often.
Orgasm
The sensation of climax can remain even when little or no semen comes out.
Fertility
Dry/retrograde ejaculation can significantly reduce natural fertility even when erections and orgasm remain normal.
If future fertility or ejaculation preservation matters, raise it before treatment—not after a procedure has been selected.
Urinary Side Effects After BPH Procedures
Burning and Frequency
These are common during early healing because the urethra and prostate bed are irritated. They generally improve over days to weeks.
Blood in the Urine
Light hematuria can occur after many transurethral procedures. Bleeding can intermittently increase as scabs separate during healing.
Temporary Urinary Retention
Swelling can temporarily make urination difficult even after a procedure intended to improve flow. A catheter may be required until swelling settles.
Temporary Urinary Leakage
Urgency leakage or stress leakage can occur after outlet surgery, particularly enucleation of a large gland. Most temporary leakage improves, but persistent incontinence deserves urological assessment.
Urethral Stricture or Bladder-Neck Contracture
Scar tissue can narrow the urinary channel months after surgery, causing a progressively weaker stream. It may require cystoscopy and further treatment.
How Long Do Side Effects Last?
Duration depends heavily on the treatment.
| Treatment | Typical Early Recovery Pattern | Potential Lasting Issue |
|---|---|---|
| Alpha blockers | Side effects occur while medication is taken; dizziness can appear early | Ejaculatory dysfunction while taking medicine |
| 5-ARIs | Adverse effects may appear over weeks/months | Sexual side effects can persist while on treatment; discuss ongoing symptoms after stopping |
| UroLift | Urinary irritation usually days to a few weeks | Possible future retreatment |
| Rezūm | Symptoms may temporarily worsen for days/weeks before gradual improvement | Possible retreatment |
| Aquablation | Catheter/bleeding/irritation during early recovery | Ejaculation can change, but less often than TURP |
| TURP | Urinary irritation and bleeding may fluctuate for several weeks | Dry ejaculation common; stricture/incontinence less common |
| HoLEP | Urgency, burning and temporary leakage can take weeks to settle | Dry ejaculation very common; persistent leakage uncommon |
Recovery is not only about how soon you can leave hospital. A procedure can be outpatient but still cause several weeks of urinary irritation.
What About Herbal Treatment Side Effects?
The old page says herbal BPH treatments have no side effects when used correctly. That is not accurate.
Herbal and dietary supplements can cause:
- gastrointestinal symptoms;
- headache or dizziness;
- allergic reactions;
- drug interactions;
- variable dosing and product quality;
- and, depending on the ingredient, liver, blood-pressure or bleeding problems.
Also, cranberry and uva-ursi are not established treatments for BPH. Uva-ursi in particular should not be promoted as a routine male urinary remedy.
Saw palmetto has generally shown little or no overall benefit in high-quality evidence, with only limited formulation-specific nuance in EAU guidance.
How to Reduce the Risk of Treatment Side Effects
- Choose treatment according to anatomy and goals. A procedure that is excellent for one prostate may be a poor fit for another.
- Tell your doctor about every medicine and supplement. This includes blood thinners, blood-pressure drugs and herbal products.
- Discuss sexual priorities explicitly. Ask about erections, ejaculation and fertility separately.
- Ask about catheter expectations. Catheter duration differs greatly between treatments and patients.
- Follow activity restrictions. Heavy lifting and strenuous exercise can worsen bleeding during early healing.
- Stay appropriately hydrated. Do not intentionally dehydrate yourself to avoid urinating.
- Know the warning signs. Heavy bleeding, fever or inability to urinate need prompt attention.
- Ask about retreatment. A lower-side-effect procedure may come with a greater chance of needing another treatment later.
Seek Prompt Medical Care After BPH Treatment If You Have:
- complete inability to urinate;
- large blood clots or bleeding that is becoming heavy;
- fever or chills with urinary symptoms;
- severe or rapidly increasing pelvic/lower abdominal pain;
- fainting or severe dizziness;
- chest pain or severe shortness of breath;
- or a catheter that stops draining while the bladder becomes painful/full.
Do not try to treat acute retention by drinking less fluid. Acute urinary retention may require prompt catheter drainage.
Dr. Albana’s Note
When patients compare BPH treatments, I encourage them not to ask only which option has the fewest side effects. A treatment can look attractive because recovery is short or ejaculation is preserved, but it may provide less improvement or carry a greater chance of retreatment.
The better question is: Which side effects matter most to me, and what benefit am I receiving in exchange for those risks?
For example, a sexually active man who strongly prioritizes ejaculation may reasonably consider UroLift, Rezūm or Aquablation if his anatomy is suitable. A man with severe obstruction or a very large prostate may prioritize maximal durability and accept the high likelihood of dry ejaculation after HoLEP.
I also separate erectile function from ejaculation. Many patients hear “sexual side effects” and assume they will become impotent. In reality, TURP or HoLEP may leave erections intact while changing the direction or amount of semen during ejaculation.
Finally, temporary symptoms should be distinguished from complications. Burning, urgency, a small amount of blood and short-term catheter use can be expected after some procedures. Fever, inability to urinate, heavy bleeding or a blocked catheter are different and require medical attention.

Frequently Asked Questions About BPH Treatment Side Effects
Which BPH treatment has the fewest sexual side effects?
UroLift and Rezūm have particularly favorable ejaculation-preservation profiles in suitable patients, and Aquablation preserves antegrade ejaculation more often than TURP in randomized trials. Suitability depends on prostate anatomy and symptom severity.
Does TURP cause erectile dysfunction?
ED can occur after TURP, but the more predictable sexual change is retrograde/dry ejaculation. Erections, ejaculation and orgasm should be discussed separately.
Does HoLEP cause impotence?
HoLEP generally does not have a major negative effect on erectile function compared with TURP, but dry/retrograde ejaculation is very common.
Is urinary leakage permanent after HoLEP?
Temporary stress leakage can occur, especially after removal of a large obstructing adenoma, and often improves with healing and pelvic-floor recovery. Persistent incontinence is much less common and should be reassessed by the treating urologist.
Can finasteride cause sexual side effects?
Yes. Reduced libido, erectile dysfunction, lower semen volume and ejaculation changes are recognized adverse effects. The likelihood varies between individuals.
Why does tamsulosin affect ejaculation?
Selective alpha blockade changes smooth-muscle function involved in emission/ejaculation. Ejaculatory dysfunction is more frequent with highly selective agents such as tamsulosin and silodosin.
Does Rezūm make symptoms worse before they get better?
It can. The treatment causes tissue swelling and inflammation before the treated tissue shrinks, so urgency, burning, weak flow or catheter dependence may temporarily worsen during early recovery.
Can I choose a procedure just to avoid medication side effects?
Yes, provided you understand the procedure’s own risks, expected symptom benefit, durability, recovery and retreatment rate. A patient preference for procedural treatment is a legitimate part of shared decision-making.
