Most men will have a stretch where erections are not what they used to be. For some it is a one-off after a stressful week or too much alcohol; for others it becomes a pattern that quietly reshapes confidence, mood and a relationship. Erectile dysfunction (ED) is the persistent difficulty getting or keeping an erection firm enough for satisfying sex. It is one of the most common things men raise in a men's health clinic, and the data backs that up: the Massachusetts Male Aging Study found that around 52% of men aged 40 to 70 reported some degree of ED, with prevalence rising as men get older.
The reason a proper assessment matters is that an erection is, in large part, a vascular event. The same small arteries that fill the penis are affected early by the things that damage blood vessels everywhere else. Because of this, ED can be an early warning sign of cardiovascular disease, diabetes or high blood pressure, sometimes years before a heart problem shows up. So while the goal is to get erections working again, a good clinic also uses ED as a prompt to check what is going on underneath.
This guide walks through what drives ED, the full range of treatments available in Bangkok, honest pricing in Thai baht with a comparison to US and UK costs, how to judge realistic results, the risks worth knowing, and how to pick a clinic you can trust. None of this replaces a consultation. Several of these treatments, in particular the oral tablets, are prescription-only and carry real interactions, so the safe path always starts with a doctor.
What causes erectile dysfunction
ED is usually multifactorial, which is the clinical way of saying more than one thing is often involved. The StatPearls urology reference groups the causes into organic (a physical mechanism), psychogenic (psychological) and mixed, and in practice most men sit somewhere in the middle.
The main contributors a doctor looks for:
Vascular. Reduced blood flow from atherosclerosis, high blood pressure, high cholesterol or diabetes. This is the most common organic cause in men over 40 and the one most tied to general heart health.
Hormonal. Low testosterone, thyroid problems or raised prolactin. Low testosterone tends to hit desire and energy as much as the erection itself, which is a useful clue.
Neurological. Nerve signalling problems from diabetes, spinal issues, multiple sclerosis, or as a consequence of pelvic or prostate surgery.
Psychological. Performance anxiety, stress, depression and relationship strain. These are especially common in younger men and often coexist with a physical trigger.
Lifestyle and medications. Smoking, heavy alcohol, poor sleep, obesity and a sedentary routine all matter. So do several common drugs, including some blood pressure tablets and antidepressants.
One practical distinction: men who still get firm morning or spontaneous erections, but lose rigidity during sex, more often have a psychological or anxiety component. Men whose erections have faded gradually across all situations are more likely to have a physical, usually vascular, cause. It is rarely that clean, which is why testing helps. If your main issue is drive rather than rigidity, it is worth reading our explainer on erectile dysfunction vs low libido, and if quick climax is the real problem, premature ejaculation vs erectile dysfunction untangles the two.
How ED is assessed
A sensible work-up is quick and not invasive. At Menscape it usually involves a focused history (including which medications you take and your cardiovascular risk), a brief physical examination, and blood tests covering testosterone, blood sugar and cholesterol. Where blood flow is the suspected problem, a penile Doppler ultrasound can measure how well the arteries fill and whether blood leaks back out too quickly. A short questionnaire such as the IIEF helps grade severity and track progress later. The point is to match the treatment to the cause rather than handing every man the same tablet.
Treatment options in Bangkok
Think of ED treatment as a ladder. Most men start near the bottom with the simplest, lowest-risk options and only climb if needed. Many do best with a combination, for example tablets plus addressing a hormone issue, or shockwave alongside lifestyle change.
1. Lifestyle and treating the underlying condition
Stopping smoking, cutting alcohol, losing weight, sleeping properly and exercising regularly genuinely improve erections, because they improve the blood vessels. Controlling diabetes, blood pressure and cholesterol does the same. For mild or stress-related ED this is sometimes enough, and it makes every other treatment work better. It is the least glamorous option and the one with the best long-term return.
2. Oral PDE5 inhibitors (the first-line medicines)
Tablets such as sildenafil (the generic of Viagra) and tadalafil (the generic of Cialis) are the standard first-line treatment, and the AUA guideline gives them a strong recommendation. They work by blocking the PDE5 enzyme, which relaxes the smooth muscle in the penis and lets blood flow in when you are aroused. They do not create desire and they do not work without sexual stimulation.
The practical differences between agents matter more than most men realise:
Sildenafil acts in roughly 30 to 60 minutes and lasts around 4 to 6 hours. A heavy or fatty meal can blunt and delay it.
Tadalafil has a much longer window, up to about 36 hours, which is why it is the more forgiving choice for spontaneity. Food affects it less.
Vardenafil behaves similarly to sildenafil.
Avanafil is the fastest-acting, sometimes working within about 15 to 30 minutes.
There is also a daily low-dose tadalafil option (a small tablet taken every day) for men who want erections to be possible at any time without planning around a pill, and which can also help urinary symptoms from an enlarged prostate. We go much deeper into brands, doses and what each costs in our companion guide to ED medication in Bangkok and its costs.
One non-negotiable safety point: PDE5 inhibitors must never be combined with nitrate heart medicines (for example glyceryl trinitrate or isosorbide), because together they can cause a dangerous drop in blood pressure. This is why these tablets are prescription-only and why a proper history is essential, not a formality.
3. Testosterone therapy
When blood tests confirm genuinely low testosterone, testosterone replacement can restore desire, energy, mood and, in some men, erectile function. It is not an ED treatment on its own and will not help men with normal levels, so it should only follow proper testing and be monitored over time. It often works best alongside a PDE5 inhibitor rather than instead of one. Our overview of testosterone therapy for men explains who is a candidate and how monitoring works.
4. Low-intensity shockwave therapy (LiSWT)
Shockwave therapy uses gentle acoustic pulses applied to the penis across a course of sessions, with the aim of stimulating new blood-vessel growth and improving natural blood flow. A 2022 systematic review and meta-analysis of 16 randomised controlled trials found that LiSWT significantly improved erectile-function scores (IIEF) and erection hardness, with the clearest benefit in men with mild-to-moderate, vascular ED. It is appealing because it targets the underlying blood supply rather than masking the problem, and some men reduce their reliance on tablets afterward.
Two honest caveats. First, the AUA still classes shockwave as investigational, meaning the evidence is promising but not yet definitive, and results vary between men. Second, it is not a cure and benefits can fade over a year or two, so maintenance sessions are sometimes needed. We compare it head-to-head with tablets in is shockwave therapy better than Viagra, and the full treatment lives on our shockwave therapy service page.
5. Regenerative options: PRP and exosomes
Platelet-rich plasma (PRP) uses a concentrate from your own blood, injected into the penis with local anaesthetic, to deliver growth factors intended to support tissue and blood flow. Exosome therapy uses laboratory-prepared signalling vesicles toward a similar goal. These are newer, the evidence base is still maturing, and they are best understood as adjuncts for selected men rather than proven stand-alone cures. They are often combined with shockwave. If you are weighing these up, see PRP for erectile dysfunction, exosome therapy for erectile dysfunction and the comparison in exosome vs PRP.
6. Intracavernosal injections
Self-administered injections (commonly alprostadil) into the side of the penis reliably produce an erection within minutes and work even when tablets do not, because they act directly on the blood vessels rather than through the nerves. The trade-off is the injection itself and a small risk of a prolonged, painful erection (priapism) that needs urgent care. With good teaching most men manage them well, and they are a strong option after prostate surgery.
7. Vacuum erection devices
A vacuum pump draws blood into the penis mechanically, and a constriction ring at the base holds it there. It is drug-free, low-cost and safe, which suits men who cannot take medication. The erection can feel cooler and less natural, and it takes practice, but it is a legitimate and underused option.
8. Penile implant surgery
When nothing else restores reliable erections, a penile implant (prosthesis) is the definitive option. A three-piece inflatable device places cylinders in the penis, a small pump in the scrotum and a fluid reservoir, letting a man create a firm erection on demand and return to flaccid afterward. Satisfaction is high: a review in *Advances in Urology* reported satisfaction rates broadly in the 76 to 97% range for three-piece inflatable prostheses, among the highest of any ED treatment. It is genuine surgery with the usual surgical risks, and it permanently changes the natural erection mechanism, so it is reserved for men who have exhausted other routes. Explore device types and brands on our penile implant surgery options guide and the penile implant surgery service page.
Erectile dysfunction treatment cost in Bangkok (THB and USD)
A major reason men travel to Bangkok is price, especially for shockwave, regenerative therapy and implants, where Thai costs commonly run well below the US, UK and Australia for comparable devices and surgeons. The table below gives indicative ranges across the whole treatment ladder. These figures are for orientation only and should be confirmed at consultation, since the right plan, dose and number of sessions vary by person.
Treatment | Bangkok price (THB) | Bangkok price (USD approx.) | Typical US / UK cost | Indicative saving in Bangkok |
Doctor consultation / ED evaluation | 500 – 2,000 | ~15 – 60 | USD 150 – 400 | Often 70%+ |
Generic sildenafil (per tablet) | 40 – 120 | ~1 – 4 | USD 10 – 90 brand-equivalent | Large on brand pricing |
Generic tadalafil (per tablet) | 60 – 150 | ~2 – 5 | USD 10 – 90 brand-equivalent | Large on brand pricing |
Daily low-dose tadalafil (per tablet) | 30 – 80 | ~1 – 2.5 | USD 2 – 9 | Comparable to modest |
Testosterone blood test | 800 – 6,000 | ~25 – 180 | similar or higher | Variable |
Low-intensity shockwave (full course) | 18,000 – 50,000 | ~530 – 1,500 | USD 2,500 – 6,000+ | Roughly 50 – 75% |
PRP / regenerative session | 15,000 – 40,000 | ~440 – 1,200 | USD 1,500 – 4,000+ | Roughly 50 – 70% |
Penile injections (per vial / programme) | varies, confirm at consult | , | higher | Variable |
Three-piece inflatable penile implant | 449,000 – 650,000 | ~13,000 – 20,000 | USD 24,000 – 48,000 / £17,600 – 36,000 | Roughly 50 – 70% |
Pricing is indicative for 2026 and confirmed only after assessment. Tablet pricing is consistent with our dedicated ED medication cost guide.
What drives the cost
Treatment type. Tablets are inexpensive; surgery sits at the top because of the device, the operating theatre, anaesthesia and the hospital stay.
Brand vs generic. Brand-name Viagra and Cialis cost several times more than the identical-molecule generics, which are equally effective when sourced from a licensed clinic.
Number of sessions. Shockwave and regenerative therapy are courses, not single visits, so the package size drives the total.
The device, for implants. A three-piece inflatable implant costs more than a malleable (bendable) one, and brand and model affect the price.
What is included. Implant quotes should state whether anaesthesia, the device, hospital stay, medicines and follow-up are bundled in.
Clinic vs pharmacy. A clinic includes medical oversight and a prescription, which is the safe route, rather than buying loose pills over a counter.
Who is a candidate, and who is not
Most men with ED are candidates for *something* on the ladder; the question is which rung. The starting point on the ladder, lifestyle plus PDE5 inhibitors, suits the majority of men with mild-to-moderate ED and no contraindications.
PDE5 inhibitors are not appropriate, or need specialist caution, if you:
take nitrate medicines for chest pain or heart disease (an absolute contraindication, because the combination can cause severe, dangerous low blood pressure)
take certain alpha-blockers or the blood-pressure drug riociguat
have had a recent heart attack or stroke, unstable angina, or are advised against sexual activity for cardiac reasons
have very low blood pressure, severe liver disease, or certain inherited retinal conditions
This is exactly why these tablets are prescription-only. Buying them online or from a market stall bypasses the one check that keeps them safe.
For the procedures, candidacy is more individual. Shockwave and regenerative therapy tend to suit men with vascular, mild-to-moderate ED and are less useful in severe or end-stage cases. Implant surgery is generally reserved for men in whom other treatments have failed or are unsuitable, who understand it permanently alters the natural erection, and who are fit for an operation. Active genital infection, poorly controlled diabetes or unrealistic expectations are reasons to pause and reassess. A consultation exists to sort this out properly.
What recovery and the patient journey look like
For tablets, there is no recovery period; you take the medicine ahead of activity (or daily, for low-dose tadalafil) and titrate the dose with your doctor over a few attempts to find what works.
For a shockwave or PRP course, expect a series of short outpatient visits, often once or twice a week over several weeks. Sessions take around 15 to 20 minutes, are generally well tolerated, and you can return to normal activity, including sex, the same day in most cases. Results build gradually over weeks to a few months as tissue responds, rather than appearing immediately.
For a penile implant, the broad stages are:
Procedure. Performed under spinal or general anaesthesia, commonly with a one-night hospital stay.
First 1 to 2 weeks. Expect swelling, bruising and soreness, managed with pain relief; you rest and avoid strenuous activity.
Weeks 2 to 6. Gradual return to daily activities; the surgeon guides when wounds have settled.
Around 6 weeks. The device is typically activated and you are taught to use the pump, after which sexual activity usually resumes.
These timelines are typical, not guarantees, and your surgical team's instructions take precedence.

How well do treatments work
Results depend heavily on the cause and on choosing the right treatment, but realistic, evidence-aligned expectations look roughly like this:
PDE5 inhibitor tablets help a large majority of men, with response commonly cited in the region of 60 to 70% and higher in men without significant nerve damage. Dose adjustment and correct timing improve the odds, and a first "failure" is often just the wrong dose or technique.
Low-intensity shockwave produced statistically significant improvements in erectile-function scores and erection hardness across 16 randomised trials, best in mild-to-moderate vascular ED, though benefit can be modest and may need maintenance.
Testosterone therapy improves sexual function mainly in men with genuinely low levels, often through restored desire as much as rigidity.
Penile implants carry the highest satisfaction of any ED treatment, reported broadly in the 76 to 97% range for three-piece inflatable devices, because they reliably produce an erection on demand.
A combination approach, for instance shockwave plus tablets, or treating a hormone problem alongside an oral medicine, often outperforms any single treatment.
Risks and side effects
Every treatment has trade-offs. Most are mild, but a few warrant urgent attention.
Common, usually mild effects of PDE5 inhibitor tablets include headache, facial flushing, nasal congestion, indigestion and, with sildenafil, an occasional brief blue tinge to vision. These tend to settle and often lessen with a dose change.
Procedure-related risks include bruising, soreness or minor bleeding after shockwave or PRP injections; with implant surgery, the recognised surgical risks are infection, mechanical failure of the device over time, and the irreversibility of the natural erection mechanism once cylinders are placed.
Seek urgent medical care if you experience any of the following:
an erection lasting more than 4 hours (priapism), which is a medical emergency and most associated with injections, but possible with tablets
chest pain, severe dizziness or fainting during or after sex, especially on a tablet
sudden loss or marked decrease of vision or hearing
after implant surgery: spreading redness, fever, increasing pain or discharge from the wound, which can signal infection
If you take nitrates for your heart, do not take a PDE5 inhibitor and do not let anyone sell you one without disclosing this, because the interaction can be life-threatening.
How to choose a safe ED clinic in Bangkok
The Bangkok market ranges from excellent specialist clinics to street vendors selling counterfeit pills. The trust checklist is straightforward:
A real consultation and history. A clinic that prescribes without asking about your heart, medications and risk factors is cutting the one corner that matters most.
Licensed, genuine medication. Buy only from a licensed clinic or pharmacy. Counterfeit ED pills are common in tourist areas and may contain the wrong dose or contaminants.
A men's-health or urology focus. Sexual function sits at the crossroads of vascular, hormonal and psychological health, so depth of expertise counts.
Transparent pricing. Clear THB prices, and for implants an itemised quote stating what is and is not included.
Honest expectations. Be cautious of anyone promising a guaranteed cure, particularly for newer regenerative treatments where the evidence is still developing.
Red flags to walk away from: market or "herbal" performance pills, online pharmacies with no licensing or prescription, prices that look too good to be true, and any provider who skips your medical history.

The bottom line
Erectile dysfunction is common, often a window into wider health, and in most men genuinely treatable. The smart approach is to start with an assessment that finds the cause, begin on the lowest effective rung of the ladder, and step up only if needed. Bangkok offers the full range, from inexpensive generic tablets to advanced regenerative therapy and implant surgery, frequently at a fraction of Western prices. What it should never offer is a shortcut around the medical consultation. Because several of these treatments are prescription-only and carry real interactions, the first and most important step is a private conversation with a qualified doctor.
If erections have not been reliable for a while, book a confidential ED consultation at Menscape Bangkok and let an assessment, not guesswork, decide your next step.
Frequently Asked Questions
Is erectile dysfunction permanent or can it be reversed?
For most men it is treatable and often reversible, particularly when it is caught early and the underlying cause is addressed. Mild and stress-related ED can resolve with lifestyle change alone, and the majority of men respond to tablets. Even when erections cannot be restored medically, a penile implant reliably produces an erection on demand. Permanent, untreatable ED is the exception rather than the rule.
How quickly do ED treatments work?
It depends on the treatment. Oral PDE5 inhibitors act within about 15 to 60 minutes per dose, and injections within minutes. Shockwave, PRP and exosome therapy are different: they build results gradually over several weeks to a few months as tissue and blood flow respond. Testosterone therapy, where appropriate, also takes weeks. A penile implant is usable for sex once you have recovered, typically around six weeks after surgery.
Are generic ED tablets as good as Viagra and Cialis?
Yes, when bought from a licensed clinic or pharmacy. Generic sildenafil contains the same active molecule as Viagra, and generic tadalafil the same as Cialis, at the same doses, and they work the same way. The main difference is price, with generics costing a fraction of the brand. The risk lies not in generics themselves but in counterfeit pills from unlicensed sellers, which is why sourcing matters.
Can I drink alcohol with ED medication?
A small amount of alcohol is generally fine with PDE5 inhibitors. The problem is heavier drinking, which both impairs erections directly and, combined with the blood-pressure-lowering effect of the tablet, can cause dizziness or low blood pressure. If you plan to drink, keep it modest. This is something to discuss with your doctor at consultation, especially if you take other medicines.
Who should not take ED tablets?
PDE5 inhibitors are not safe for men taking nitrate heart medicines (such as glyceryl trinitrate or isosorbide), because the combination can cause a severe, dangerous drop in blood pressure. They also need caution with certain alpha-blockers, with riociguat, after a recent heart attack or stroke, and in some eye, liver and blood-pressure conditions. This is precisely why the tablets are prescription-only and require a medical history first.
Does shockwave therapy actually work for ED?
The evidence is encouraging but not definitive. A 2022 meta-analysis of 16 randomised trials found low-intensity shockwave significantly improved erectile-function scores and erection hardness, with the best results in men with mild-to-moderate, blood-flow-related ED. However, leading guidelines still class it as investigational, the benefit can be modest, and effects may fade over time, so some men need maintenance sessions. It suits selected men rather than everyone.
How much does ED treatment cost in Bangkok?
It spans a wide range. Generic tablets are inexpensive, roughly THB 40 to 150 each, and a consultation is around THB 500 to 2,000. A full shockwave course is commonly THB 18,000 to 50,000, regenerative sessions are in a similar bracket, and a three-piece inflatable penile implant runs about THB 449,000 to 650,000. For the procedures and devices, Bangkok prices are frequently 50 to 70% below US and UK costs. All figures are indicative and confirmed at consultation.
Can stress or anxiety cause erectile dysfunction in younger men?
Yes, and in younger men psychological factors such as performance anxiety, stress and relationship strain are among the most common causes. A useful clue is still having firm morning or spontaneous erections but losing rigidity during sex, which points toward a psychological component rather than a purely physical one. These cases often respond well to a short course of tablets to break the anxiety cycle, alongside addressing the stress itself.
Will my consultation and treatment be confidential?
Yes. Sexual-health consultations at a men's-health clinic are private and discreet, which is one reason many men prefer a specialist clinic to a general setting. A confidential consultation is also the safe and necessary first step, because it lets the doctor check your medical history, screen for interactions such as nitrates, and match the treatment to the actual cause rather than guessing.
