If you have searched for a way to treat erectile dysfunction (ED) that does not involve taking a tablet every time, you have probably come across PRP, often sold under the brand-style name "P-Shot" or "Priapus Shot." The pitch is appealing: draw a little of your own blood, spin out the platelet-rich part, inject it, and let your body's own growth factors rebuild the tissue. No drugs, no implants, no foreign material.
That pitch is partly true and partly marketing. PRP is a real procedure with a plausible biological rationale and a reassuring safety record. It is also a treatment that two of the best-designed studies to date found worked no better than a saline injection, and that the American Urological Association-guideline) still labels "experimental." Both of those things can be true at once, and a clinic that only tells you the first half is not giving you the full picture.
This guide is written for men who want the honest version before they spend money. We cover what PRP actually is, what the evidence does and does not show, realistic Bangkok pricing against US and UK costs, who is and is not a sensible candidate, the risks, and the alternatives that have stronger backing. PRP for ED requires a medical consultation, and in many countries the blood handling and injection must be done under a doctor's supervision, so treat this as background for that conversation, not a substitute for it.
What PRP for erectile dysfunction actually is
PRP stands for platelet-rich plasma. Your blood is mostly red cells, white cells, plasma (the liquid part), and platelets. Platelets are best known for clotting, but they also carry growth factors, signalling proteins that tell surrounding cells to repair, multiply, and form new small blood vessels. PRP is simply your own blood spun in a centrifuge so the platelets are concentrated into a small volume of plasma, which is then injected back into a target tissue.
The theory behind using it for ED is that erections depend heavily on healthy blood vessels and nerves inside the penis. If concentrated growth factors can encourage new vessel growth (angiogenesis) and tissue repair, the reasoning goes, blood flow and firmness should improve. PRP is already used with reasonable evidence in some orthopaedic and dermatology settings, which is part of why it migrated into men's sexual health.
The important caveat is that a plausible mechanism is not the same as a proven result. Plenty of treatments make biological sense and then fail to beat placebo when tested properly. ED is one of the areas where that gap between theory and outcome is still wide, which we will get into below.
How the procedure works, step by step
A typical PRP session for ED is short, usually 30 to 60 minutes door to door, and is done awake in a clinic room.
Consultation and workup. A doctor reviews your ED history, medications, and general health, and ideally checks for underlying causes such as low testosterone, diabetes, or cardiovascular risk. This step matters more than the injection itself, for reasons covered later.
Blood draw. A small volume of blood, often 10 to 60 ml, is taken from a vein in your arm, the same as a routine blood test.
Centrifugation. The sample is spun in a centrifuge for several minutes to separate and concentrate the platelets into a few millilitres of plasma.
Numbing. Topical anaesthetic cream, and sometimes a local anaesthetic injection or a penile block, is applied so the injections are tolerable.
Injection. Using a fine needle, the prepared PRP is injected into specific sites along the shaft, typically the corpora cavernosa, the two columns of erectile tissue. Most protocols use a small number of injection points.
Aftercare and discharge. Pressure is applied briefly, and you go home the same day. Some clinics pair PRP with a vacuum erection device for a few weeks to encourage blood flow, though this is an add-on, not part of the PRP itself.
There is no surgery and no general anaesthetic. The discomfort most men report is from the needles and the temporary swelling, not from a long recovery.
Recovery timeline
PRP has very little downtime, which is one of its genuine selling points.
Time after the procedure | What to expect |
First 24 hours | Mild soreness, possible bruising or minor swelling at injection sites. Avoid sexual activity and strenuous exercise. |
Days 2 to 7 | Tenderness usually settles. Most men return to normal activity, including work, the same or next day. |
Weeks 2 to 4 | Any bruising resolves. Some men report early changes; many notice nothing yet. |
Months 1 to 3 | The window in which improvements, if they occur, are usually reported. |
Months 3 to 6 | Often cited as the point of "peak" effect in clinic marketing, after which results, if present, may fade. |
These timelines come from clinic protocols and observational reports. As the next section explains, whether a meaningful improvement appears at all is exactly the point where the evidence becomes uncertain.
What the evidence actually shows (the honest version)
This is the section most clinic pages skip, so read it carefully.
The strongest study design for a question like this is a randomised, double-blind, placebo-controlled trial, where neither the patient nor the assessor knows who got real PRP and who got an inactive injection. Two such trials have been published, and both are sobering.
A 2023 randomised, double-blind, placebo-controlled trial from the University of Miami, published in the *Journal of Urology*, gave 61 men with mild to moderate ED either two PRP injections or placebo, a month apart. It found PRP was safe, but there was no significant difference in erectile function between PRP and placebo, and no measurable change in penile blood flow. The authors were blunt about the gap between marketing claims and the data (Masterson et al., 2023).
A 2024 randomised controlled study in *Basic and Clinical Andrology* reached the same conclusion. Across 52 men followed for 6 months, erection scores in the PRP group and the saline placebo group were statistically indistinguishable at every time point. The authors concluded the data did not support using PRP for mild to moderate ED (Ragheb et al., 2024).
So why do you also see positive claims? Because when you pool many lower-quality and single-arm studies together, a small average benefit appears. A 2024 meta-analysis in *PLOS One* combined 12 controlled trials and 11 single-arm trials (over 1,300 patients) and found PRP was associated with a modest improvement in IIEF erection scores compared with controls, with very few side effects (Du et al., 2024). A systematic review in *World Journal of Urology* similarly described "small to moderate benefits" with mild, temporary side effects, while stressing that protocols vary widely and quality is uneven (Asmundo et al., 2024).
How can placebo-controlled trials show nothing while a meta-analysis shows a little? Mostly because many of the positive studies lacked a blinded placebo group, and ED responds strongly to placebo. When you remove that comparison, improvements look bigger than they really are.
The bottom line, and the line a responsible clinic should give you: PRP for ED is reasonable to consider, low-risk, and may help some men, but it is not proven to outperform a placebo injection in the best trials, and it is not a cure. The same systematic review notes that neither the AUA nor the European Association of Urology guidelines endorse it, and that it remains an off-label, largely trial-stage therapy. The AUA's own guideline statement classifies PRP for ED as "experimental."
Realistic results: what numbers to expect
Setting honest expectations means using the numbers from the literature, not from brochures.
Individual positive trials reported roughly a 3 to 5 point gain on the IIEF erectile function score. The pooled 2024 meta-analysis expressed its (modest) benefit not as a raw point figure but as a standardised mean difference of about 0.59, which is a small to moderate effect. For context, the smallest change most men actually notice on the IIEF is usually considered around 4 points, so even the more favourable estimates sit close to the edge of being meaningful.
In the two blinded placebo-controlled trials, that gap shrank essentially to zero.
Improvements, when reported, tend to appear within 1 to 3 months and may not be permanent, which is why clinics often suggest repeat or maintenance sessions.
Translated into plain terms: a man with mild ED might notice a modest improvement in firmness or reliability, an effect that may partly reflect the procedure and partly reflect the natural response to attention and expectation. A man with moderate to severe ED, especially from significant vascular disease, nerve damage, or after prostate surgery, should not expect PRP to restore function on its own.
Who is a candidate, and who it is not for
PRP is most often offered to men with mild to moderate ED, particularly those who prefer to avoid or cannot tolerate daily medication, and who understand the evidence is limited.
PRP is a poor choice, or outright unsuitable, for several groups:
Men with severe ED from established vascular disease, advanced diabetes, or nerve injury (for example after radical prostatectomy). The damage is usually beyond what growth factors can repair, and other treatments work better.
Men whose ED is mainly psychological (performance anxiety, relationship issues, depression). An injection does not treat the cause; counselling or sex therapy and addressing the psychological driver does.
Men who have not had the underlying cause investigated. ED is frequently the first warning sign of cardiovascular disease or low testosterone. Jumping to an injection skips the part that could matter for your life, not just your sex life.
Contraindications
Most clinics will not perform PRP, or will require clearance first, in men who have:
A bleeding or clotting disorder, or who take blood thinners such as warfarin or dual antiplatelet therapy
A platelet disorder or very low platelet count
An active infection, especially in the genital or pelvic area
Active cancer, or current chemotherapy
An unstable or uncontrolled chronic condition
This is not a complete list, and only a doctor who has reviewed your history and medications can decide whether PRP is safe for you. PRP for ED requires a medical consultation and, in regulated settings, a prescription or physician supervision for the blood handling and injection.
Risks and side effects
Because PRP uses your own blood, the risk of allergic reaction or rejection is very low, and across the published studies serious adverse events were rare. The systematic and meta-analytic reviews logged only a handful of minor complications across more than a thousand patients.
Common, usually mild and temporary:
Pain or soreness at the injection sites
Bruising or small hematomas
Mild swelling or redness
Temporary tenderness for a day or two
Less common but more serious, seek prompt medical care if you notice:
Spreading redness, heat, swelling, or pus, which can signal infection
Fever
An erection that is painful and will not go down after several hours (priapism is a urological emergency)
Significant, worsening pain or a large expanding bruise
The safety profile is one of PRP's genuine strengths. The honest framing is that the main risk is not harm, it is spending money on a treatment that may do little, while delaying a proper diagnosis.
PRP compared with other ED treatments
Treatment | How it works | Evidence strength | Typical role |
PDE5 tablets (sildenafil, tadalafil) | Improve blood flow on demand | Strong, first-line | Most men start here |
Lifestyle change (exercise, weight, smoking, sleep) | Improves vascular and hormonal health | Strong | Foundation for everyone |
Testosterone therapy (if deficient) | Corrects hormonal cause | Strong when testosterone is genuinely low | Only if blood tests confirm deficiency |
PRP / P-Shot | Growth factors aim to repair tissue and vessels | Weak and mixed; experimental per AUA | Optional, for mild ED, expectations managed |
Low-intensity shockwave therapy | Acoustic waves stimulate new vessel growth | Promising but still investigational per AUA | Often combined with or compared to PRP |
Vacuum erection device | Draws blood into the penis mechanically | Established for producing erections | Low-cost, drug-free option |
Penile injections (alprostadil) | Directly trigger an erection | Strong | For men who do not respond to tablets |
Penile implant | Surgical device | Strong for severe, refractory ED | Last-line, for severe cases |
The pattern is clear. PRP sits in the "optional, lower-evidence" tier. It is not a replacement for the proven first-line options, and any clinic presenting it as superior to PDE5 tablets or as a definitive cure is overselling it.

How much PRP for ED costs in Bangkok
Bangkok is a major destination for men's regenerative treatments, and PRP is widely available. Prices vary with the clinic, the number of injection points, the PRP preparation system used, and whether it is bundled with shockwave or other add-ons. The figures below are indicative ranges from Bangkok clinics and should be confirmed at consultation.
Item | Bangkok (THB) | Bangkok (USD approx.) | Typical US / UK price | Indicative saving |
Single PRP / P-Shot session | 15,000 – 30,000 | 420 – 830 | 1,500 – 2,200 USD (US); 1,200 – 1,500 GBP (UK) | Roughly 50 – 70% less |
Course of 2 – 3 sessions | 35,000 – 70,000 | 970 – 1,950 | 3,000 – 6,000 USD | Often 50%+ less |
PRP combined with shockwave | 25,000 – 60,000 | 700 – 1,650 | 3,000 USD+ | Substantial |
USD conversions use an approximate rate of 36 THB to 1 USD and will move with the exchange rate. The headline point is consistent across providers: a PRP session that runs 1,500 USD or more in the United States typically lands in the low hundreds of dollars in Bangkok. That price gap is real, but it does not change the underlying evidence. Cheaper does not mean more effective, and a low price is not a reason to skip the question of whether PRP is the right treatment for you at all.
What drives the cost
Number of sessions. Most protocols use 2 to 3, so the course cost matters more than the single-session price.
PRP system and concentration. Closed, higher-yield kits cost the clinic more.
Add-ons. Bundling with shockwave, a vacuum device protocol, or supplements raises the total.
Clinic positioning and doctor experience. A urologist-led men's health clinic typically prices above a general medspa.
Pre-treatment workup. Blood tests for testosterone, glucose, and cardiovascular risk add cost but are worth it.
Choosing a clinic safely, and the red flags
Because PRP is lightly regulated and easy to market, clinic selection matters more than usual. Look for:
A licensed doctor, ideally a urologist or a physician with genuine men's health experience, performing or directly supervising the procedure, not a technician alone.
A proper consultation and workup that investigates the cause of your ED before selling you an injection.
Sterile technique and single-use, properly handled blood equipment.
Honest, evidence-based counselling, including the fact that PRP is experimental and may not work better than placebo.
Transparent pricing with no pressure to buy a large package on the spot.
Walk away if you see these red flags:
Guarantees of a "cure" or permanent results
Claims that PRP is proven superior to Viagra or Cialis
No interest in why you have ED, only in selling sessions
Pressure to pay upfront for a multi-session package before any assessment
No named doctor, or vague answers about who actually performs the injection
Prices that look too good to be true, often a sign of corner-cutting on the PRP system or sterility
A clinic confident in its work will happily discuss the evidence honestly, including its limitations. That honesty is itself a quality signal.
Where Menscape fits
At Menscape in Bangkok, ED is treated as a medical problem first and a procedure second. That means a proper consultation, screening for the common underlying causes such as low testosterone and cardiovascular risk, and a frank conversation about which treatment, if any, fits your situation. For some men that is PDE5 medication and lifestyle work, for others it is shockwave or a combination, and for some PRP may be a reasonable option with realistic expectations set in advance. PRP for erectile dysfunction requires a medical consultation, and our clinicians will tell you plainly when the evidence does, and does not, support it for your case.
If you want to understand your options without the hard sell, book a confidential consultation and start with a diagnosis rather than a guess.
Frequently Asked Questions
Does PRP for erectile dysfunction actually work?
The evidence is genuinely mixed. The two best-designed studies, randomised double-blind placebo-controlled trials, found PRP worked no better than a saline injection for mild to moderate ED. A 2024 meta-analysis that pooled many studies found a small average improvement in erection scores, but much of that came from lower-quality trials without a placebo group. The fair summary is that PRP may help some men modestly, is low-risk, but is not proven and is not a cure.
Is PRP for ED FDA-approved or recommended by urology guidelines?
No. PRP for ED is used off-label. The American Urological Association guideline classifies PRP for erectile dysfunction as experimental, and the European Association of Urology does not endorse it either. It is largely a clinical-trial and elective treatment rather than standard care.
How much does PRP for ED cost in Bangkok?
Roughly 15,000 to 30,000 THB per session (about 420 to 830 USD), with a course of 2 to 3 sessions running about 35,000 to 70,000 THB. That is typically 50 to 70 percent less than US prices, where a single session often costs 1,500 USD or more. These are indicative ranges, so confirm the exact price at your consultation.
How many PRP sessions will I need?
Most Bangkok clinics recommend 2 to 3 sessions, sometimes spaced a few weeks to a month apart, and may suggest maintenance sessions later. Because any benefit can fade, the course cost matters more than the single-session price when you budget.
Is the PRP injection painful?
Most men tolerate it well. Clinics apply numbing cream and often a local anaesthetic or penile block before the injections. You may feel soreness, mild bruising, or tenderness for a day or two afterwards, but there is no real downtime and most men resume normal activity quickly.
Is PRP safe?
The safety record is reassuring. Because PRP uses your own blood, allergic reaction or rejection is very unlikely, and across more than a thousand patients in published reviews serious complications were rare. The most common effects are temporary pain, bruising, and swelling. The bigger downside is not harm but spending money on a treatment that may do little while delaying a proper diagnosis.
How soon would I see results, and how long do they last?
When improvements occur, they are usually reported within 1 to 3 months, with clinics often citing a peak around 3 to 6 months. Effects are not guaranteed to be permanent, which is why repeat or maintenance sessions are commonly suggested. Keep in mind the best trials found no benefit over placebo at any time point.
Who should not have PRP for ED?
PRP is a poor fit for men with severe ED from advanced vascular disease, diabetes, nerve damage, or after prostate surgery, and for men whose ED is mainly psychological. It is generally avoided in those with bleeding or clotting disorders, on blood thinners, with active infection or cancer, or with uncontrolled chronic illness. A doctor must review your history first.
Can PRP be combined with other ED treatments?
Yes. Clinics often combine PRP with low-intensity shockwave therapy, a vacuum erection device protocol, or PDE5 medication. Combination approaches show somewhat better numbers in pooled data, though the same evidence limitations apply. The right combination depends on your diagnosis.
Should I try PRP before or instead of Viagra or Cialis?
No. PDE5 tablets such as sildenafil (Viagra) and tadalafil (Cialis) are proven first-line treatments with strong evidence, whereas PRP is experimental. For most men the sensible path is to investigate the cause of ED, optimise lifestyle, and try established treatments first. PRP is an optional add-on for selected cases, not a replacement for proven therapy.
