For most men, erectile dysfunction is first treated with tablets such as sildenafil or tadalafil, then with injections, a vacuum pump, or a suppository. When those options stop working, or a man simply wants a reliable, on-demand erection without ongoing medication, a penile implant becomes a sensible next step. The AMS 700 LGX, made by Boston Scientific, is one of the most widely used three-piece inflatable implants worldwide, and it is a frequent request at men's health clinics in Bangkok.
What sets the LGX apart is in its name. "LGX" stands for "length and girth expansion." The cylinders are designed to grow in both directions when inflated, not just become rigid, which many men feel gives a more natural-looking erection than older fixed-girth designs. This page explains what the device is, who it suits and who it does not, realistic Bangkok pricing in both Thai baht and US dollars, what recovery actually looks like week by week, the results you can reasonably expect (with real numbers from published studies), the risks worth understanding, and how to choose a clinic safely.
A penile implant is permanent surgery that requires an in-person urology consultation and a prescription. Nothing here is a substitute for that assessment. Use it to arrive at your consultation informed and with better questions.
What the AMS 700 LGX actually is
The AMS 700 is a three-piece (sometimes called fully inflatable) penile prosthesis. Three components sit entirely inside the body, with nothing visible from the outside:
Two cylinders placed inside the erection chambers of the penis (the corpora cavernosa).
A small pump tucked into the scrotum, alongside the testicles, that you squeeze to inflate.
A fluid reservoir positioned in the lower abdomen or pelvis that holds sterile saline.
To get an erection, you squeeze the pump in the scrotum a few times. Saline moves from the reservoir into the cylinders, and the penis becomes firm. When you are finished, you press a release valve (the AMS 700 uses a one-touch "Momentary Squeeze" pump), the fluid drains back to the reservoir, and the penis returns to a soft, natural-looking flaccid state. The erection lasts as long as you want, and it is independent of blood flow, nerves, or medication.
The AMS 700 family comes in three cylinder types. The LGX expands in both length and girth. The CX expands in girth only (it stays the same length). The CXR is a narrower, shorter version for men with smaller anatomy or scar tissue. According to Boston Scientific, the LGX is the only implant on the US market with cylinders designed to expand up to roughly 25 percent in length and up to about 20 mm in girth when inflated, which is the reason length-conscious men and their surgeons often select it.
Most modern AMS 700 devices are coated with InhibiZone, a surface treatment combining two antibiotics, rifampin and minocycline, that releases slowly in the days after surgery to lower the risk of device infection. This is a genuine, evidence-backed feature rather than marketing: it is the only antibiotic-impregnated inflatable penile prosthesis on the market.
Where the LGX sits among implant types
Feature | AMS 700 LGX (3-piece inflatable) | Coloplast Titan (3-piece inflatable) | Malleable / semirigid rod |
Erection mechanism | Pump-inflated saline | Pump-inflated saline | Always semi-firm, bent up or down by hand |
Expansion when inflated | Length and girth | Girth-dominant, very rigid | None |
Flaccid appearance | Natural, soft | Natural, soft | Permanently semi-rigid |
Concealment | Excellent | Excellent | Can be harder to conceal |
Rigidity | High | Highest (firmest) | Moderate |
Best suited to | Men wanting natural feel and length preservation | Men prioritising maximum rigidity | Limited hand dexterity, lower cost, simpler surgery |
Relative complexity | Higher | Higher | Lowest |
There is no single "best" implant. The LGX is frequently chosen for its natural feel and length behaviour; the Titan is often selected when rigidity is the top priority; malleable rods suit men who want the simplest device or have trouble operating a pump. Your surgeon will match the device to your anatomy, hand strength, and goals.
AMS 700 LGX cost in Bangkok (THB and USD)
Pricing for an inflatable penile implant in Thailand is driven mostly by the device itself, which is imported and individually serial-numbered, plus operating-room time, the surgeon's fee, and your hospital stay. The figures below are indicative ranges based on current Bangkok market pricing for branded three-piece inflatable implants. Always confirm the exact, itemised quote at your consultation, because final cost depends on the specific model, your anatomy, and whether any additional correction (for example, treating curvature) is needed.
Item | Indicative Bangkok price (THB) | Indicative price (USD) |
AMS 700 LGX, all-inclusive package (device + surgery + 1-2 night stay + aftercare) | 480,000 - 820,000 | ~13,000 - 23,000 |
Device component alone (AMS 700 LGX, genuine, serial-numbered) | 260,000 - 420,000 | ~7,200 - 11,700 |
Surgeon and anaesthesia fees | 90,000 - 180,000 | ~2,500 - 5,000 |
Operating room and 1-2 night hospital stay | 70,000 - 140,000 | ~1,900 - 3,900 |
Medication, follow-up visits, activation training | included in most packages | included |
Figures are indicative and should be confirmed at consultation. A genuine three-piece inflatable device is a major part of the bill, so unusually cheap "LGX" offers are a warning sign discussed below.
Bangkok versus the US and UK
Location | Typical all-inclusive cost (3-piece inflatable) | Approximate saving vs US |
Bangkok, Thailand | ~USD 13,000 - 23,000 (THB 480,000 - 820,000) | baseline |
United States | ~USD 25,000 - 40,000+ (often higher with hospital mark-ups) | Bangkok ~40-60% lower |
United Kingdom (private) | ~GBP 16,000 - 22,000 | Bangkok broadly comparable to lower |
Cleveland Clinic notes that a penile implant typically costs between USD 12,000 and 20,000, and that the figure varies between surgeons and medical facilities. US self-pay quotes for three-piece inflatable devices frequently run higher in practice, commonly around USD 15,000 to 35,000 or more once full hospital, surgeon, and facility fees are added. The Bangkok advantage comes from lower facility and labour costs, not from a cheaper or different device: reputable Thai centres implant the same genuine, serial-numbered Boston Scientific hardware with the same InhibiZone coating used in the West. The savings should never come from a counterfeit or expired device.
What drives the price up or down
Device model and configuration. The LGX and certain pump or reservoir options cost more than basic malleable rods.
Surgeon experience and case volume. High-volume prosthetic urologists tend to command higher fees and, importantly, tend to have lower complication rates.
Hospital tier. Internationally accredited private hospitals charge more for operating-room time than smaller facilities.
Added complexity. Correcting significant Peyronie's curvature, scarring from a previous implant, or revision surgery can raise the total.
Aftercare scope. Packages that bundle activation training, wound checks, and longer-term follow-up may look pricier upfront but can be better value.
Many Bangkok clinics offer instalment or financing options. Ask whether the quote is genuinely all-inclusive or whether anaesthesia, the device, and follow-up are billed separately, because that single question explains most of the price spread between clinics.
Who is a good candidate, and who is not
An implant is usually considered when other treatments have failed or are unsuitable. You may be a reasonable candidate if:
You have erectile dysfunction that no longer responds adequately to tablets, injections, a vacuum device, or suppositories.
Your ED has a clear physical (organic) basis, for example after prostate surgery (radical prostatectomy), with diabetes, Peyronie's disease with deformity, or significant vascular disease.
You have severe Peyronie's disease, where an implant can straighten the penis while restoring rigidity.
You understand the surgery is permanent, because the natural erectile tissue is altered during implantation, and you want a reliable, spontaneous solution without ongoing medication.
Who it is NOT for, and contraindications
This is just as important. A penile implant is generally not appropriate, or must be delayed, in these situations:
Any active infection, whether a urinary tract infection, a skin infection in the genital or groin area, or infection elsewhere in the body. Operating during an active infection sharply raises the risk of the device becoming infected, and surgery should be postponed until it clears.
ED that can still be managed with tablets, injections, or a vacuum device. Implant surgery is irreversible, so simpler options are exhausted first.
ED that is primarily psychological without a physical cause, which is usually better treated with counselling, medication, or sex therapy.
Uncontrolled diabetes or poorly managed health conditions, which increase infection and healing risks. These are often optimised first, then re-assessed.
Unrealistic expectations, for example expecting the implant to dramatically increase penis size or to restore lost sensation. An implant restores rigidity and function; it does not change sensation, orgasm, or fertility, and it does not make the penis substantially larger than its natural erect dimensions.
Mayo Clinic notes that a penile implant is usually not recommended until other erectile dysfunction treatments have been tried, and that surgery should be avoided if you have an active infection, such as a urinary tract or other infection. A thorough consultation, often including a review of your medications, cardiovascular health, and sometimes a vascular assessment, is what separates a good candidate from a poor one.
The procedure, step by step
AMS 700 implantation is a planned operation, usually taking around 60 to 90 minutes, performed under general or spinal anaesthesia. A simplified outline:
Preparation. You are given antibiotics, and the surgical area is carefully cleaned and shaved immediately before surgery to reduce infection risk. Many surgeons use a "no-touch" technique to keep the device from contacting skin.
Incision. A small incision is made, typically where the base of the penis meets the scrotum (penoscrotal) or in the lower abdomen (infrapubic). Scarring is generally minimal and well hidden.
Placing the cylinders. The erectile chambers (corpora cavernosa) are gently dilated, measured, and the two LGX cylinders are sized precisely and inserted. Accurate sizing is critical for both comfort and length preservation.
Placing the pump and reservoir. The pump is positioned in the scrotum and the reservoir in the lower abdomen or pelvis, then all three components are connected and tested.
Testing and closure. The surgeon inflates and deflates the device to confirm it works and that the penis is straight, then closes the incision. The device is usually left partially inflated initially to reduce swelling and scarring.
You will typically stay one to two nights. A catheter may be placed briefly, and you go home with antibiotics and pain relief.
Recovery timeline, week by week
Healing is gradual, and rushing it is the most common avoidable mistake. A typical staged recovery looks like this, though your surgeon's instructions always take priority:
Days 1 to 7. Expect swelling, bruising, and discomfort in the penis and scrotum, which is normal. Pain settles noticeably after about a week, per Cleveland Clinic. Keep the area clean, take antibiotics as prescribed, and limit walking and standing. Most men who fly home wait until at least day 5 to 7, once swelling and any catheter issues have settled, but discuss travel timing with your surgeon.
Weeks 1 to 2. Swelling improves. You may return to a desk job after about a week; physically demanding work needs two to four weeks off. Avoid heavy lifting and strenuous activity.
Weeks 2 to 4. You return for a wound check. Around this point, many surgeons begin activation training, teaching you to inflate and deflate the pump and starting gentle daily cycling to keep the chambers supple.
Weeks 4 to 6. Most men are cleared to resume sexual activity at around four to six weeks, once healing is confirmed and you are comfortable operating the device. Cleveland Clinic advises avoiding sex for at least four weeks.
Beyond 6 weeks. Comfort and confidence with the device continue to improve over the following months. Follow-up visits taper off, but long-term support should remain available.
If you are travelling to Bangkok specifically for this procedure, plan for a stay long enough to cover the operation, the early healing window, and at least one in-person follow-up, rather than flying out within a day or two.
Results you can realistically expect
The honest summary is that satisfaction with modern three-piece implants is high, durability is good, and the numbers below come from published patient series rather than promotional claims.
Satisfaction. Cleveland Clinic states that over 90 percent of people with a penile implant are happy with the results. In a study of 45 men who received the AMS 700 LGX, published in the Asian Journal of Andrology, 80 percent reported satisfaction with their final penile length at 12 months.
Length behaviour. That same LGX series found stretched flaccid length increased by a mean of about 1.1 cm at 12 months, and when fully inflated the penis measured roughly 10 percent (about 1.3 cm) longer than baseline. A larger Korean series of 342 men, published in BMC Urology, similarly reported mean stretched length rising from about 11.1 cm to 12.2 cm at 12 months. These are modest, real gains in the context of length preservation, not dramatic enlargement.
Function and confidence. In that Korean cohort, IIEF satisfaction-domain scores improved significantly from baseline at 3, 6, and 12 months after surgery. An implant produces a reliable, on-demand erection independent of medication.
Durability. A 2024 narrative review in the AME Medical Journal reports AMS 700 mechanical reliability of roughly 90 to 93 percent at 5 to 6 years and about 77 to 81 percent at 10 years, with fluid leakage from tubing or cylinder wear being the most common cause of eventual failure. Cleveland Clinic notes implants last around 20 years on average before wearing out.
It is worth being clear about what an implant does not do. It does not increase sensation, change orgasm or ejaculation in men who still produce it, restore fertility, or make the penis larger than its natural erect size. It restores the ability to have a firm erection whenever you choose.

Risks and side effects
Penile implant surgery is generally safe in experienced hands, but it is real surgery with real risks. Understanding them is part of giving informed consent.
More common or expected, usually temporary:
Swelling, bruising, and pain for one to two weeks.
Temporary changes in penile sensation.
A slightly different feel to erections, since the mechanism is mechanical.
Some men perceive a small loss of length compared with their best historical erection, which is one reason the LGX is chosen.
Less common but more serious:
Infection of the device. This is the most feared complication because an infected implant usually has to be removed. The InhibiZone antibiotic coating exists specifically to lower this risk; in one long-term study of diabetic patients, antibiotic-coated AMS 700 implants reduced infection-related revision substantially compared with uncoated devices. Diabetic and immunocompromised men carry higher baseline risk.
Mechanical failure of a cylinder, pump, tube, or reservoir over the years, which may require a revision operation.
Erosion or migration, where part of the device pushes against or through tissue. Mayo Clinic specifically lists internal erosion or adhesion as a risk that can require device removal.
Persistent pain or difficulty operating the pump, which usually improves with time and training.
Seek urgent medical care if you notice
Treat the following as red flags and contact your surgeon or attend an emergency department promptly:
Fever, spreading redness, increasing warmth, or pus or discharge from the incision, which can signal infection.
Severe or worsening pain that is not controlled by your prescribed medication.
A part of the device becoming visible or eroding through the skin.
Sudden swelling, a hard lump, or significant new bruising in the days after surgery.
An erection that will not deflate or any sign the device has malfunctioned.
Prompt attention to a device infection gives the best chance of saving the implant or managing the problem with fewer consequences.
Choosing a safe clinic in Bangkok
Outcomes with penile implants depend heavily on surgeon experience and on the integrity of the device supply chain. Bangkok has excellent prosthetic urologists, but quality varies, so do your due diligence.
Look for:
A board-certified urologist who regularly performs penile prosthesis surgery, ideally one who can speak to their case volume. Higher-volume implant surgeons generally report lower complication rates.
A named, licensed surgeon. Strong Thai clinics list their urologists by name with their Thai medical-license numbers; you should be able to verify who is operating on you.
An accredited hospital or surgical facility with proper infection-control standards and an experienced anaesthesia team.
A genuine, sealed, serial-numbered AMS 700 LGX, with the serial number documented and given to you. This is your proof of authenticity and your warranty record.
Comprehensive aftercare, including activation training, wound checks, and a clear plan for long-term follow-up and warranty support.
Red flags to walk away from:
LGX pricing that is dramatically below the market, which can indicate a counterfeit, expired, or grey-market device.
A clinic that cannot or will not show the device serial number or verify authenticity.
No named urologist, or refusal to confirm exactly who will perform the surgery.
No structured follow-up, or aftercare that ends the moment you leave the hospital.
Pressure to decide quickly, or claims that sound too good to be true, such as guaranteed size increases.
A trustworthy clinic will welcome these questions and answer them in writing.

Frequently Asked Questions
Does the AMS 700 LGX make my penis permanently longer?
Not dramatically. The LGX is designed to preserve and modestly improve length, not to enlarge the penis. Published studies of LGX patients found stretched flaccid length increased by roughly 1 cm at 12 months, and the inflated penis measured about 10 percent longer than baseline. Think of it as protecting the length you have and giving a more natural-looking erection, rather than a true enlargement procedure.
How much does an AMS 700 LGX implant cost in Bangkok?
As an indicative range, an all-inclusive AMS 700 LGX procedure in Bangkok typically costs about THB 480,000 to 820,000, or roughly USD 13,000 to 23,000, covering the genuine device, surgery, a one to two night hospital stay, and aftercare. That is commonly 40 to 60 percent below US pricing for the same branded device. The exact figure depends on the hospital, surgeon, and your anatomy, so confirm an itemised quote at your consultation.
Is the LGX better than the Coloplast Titan?
Neither is universally better; they suit different priorities. The LGX is often chosen for its natural feel and its ability to expand in both length and girth when inflated. The Titan is frequently selected when maximum rigidity is the main goal. The right choice depends on your anatomy, hand strength, and what matters most to you, which your surgeon will assess during the consultation.
How soon can I have sex after the surgery?
Most men are cleared to resume sexual activity at around four to six weeks, once healing is confirmed and they are comfortable operating the pump. Cleveland Clinic advises avoiding sex for at least four weeks. Your surgeon will give a personalised timeline based on how you heal and on your activation training progress.
How long does an AMS 700 implant last?
Modern three-piece inflatable implants are durable. Published data show AMS 700 mechanical reliability of about 90 to 93 percent at 5 to 6 years and roughly 77 to 81 percent at 10 years, and Cleveland Clinic notes implants last around 20 years on average. The most common reason a device eventually needs replacing is fluid leakage from worn tubing or cylinders, which can be addressed with a revision operation.
What is the biggest risk, and how is it reduced?
Device infection is the most serious complication, because an infected implant usually has to be removed. The AMS 700's InhibiZone coating, which slowly releases two antibiotics after surgery, is designed specifically to lower this risk and has been shown to reduce infection-related revisions, particularly in higher-risk patients such as those with diabetes. Choosing an experienced surgeon and an accredited facility with strict infection control further reduces the risk. Seek urgent care for fever, spreading redness, or discharge from the wound.
Will the implant affect my sensation, orgasm, or fertility?
No. The implant restores the ability to have a firm erection on demand, but it does not change skin sensation, the feeling of orgasm, or ejaculation in men who still produce it, and it does not affect fertility. If you could orgasm before surgery, you generally still can afterwards. The implant works on rigidity, not on the nerves responsible for sensation or climax.
Can I travel home soon after the procedure?
Most men who travel for the surgery wait until at least day 5 to 7 before flying, once early swelling has settled and any catheter has been removed, but this should be agreed with your surgeon. If you are coming to Bangkok specifically for the implant, plan a stay long enough to cover the operation, the early healing window, and at least one in-person follow-up visit rather than leaving within a day or two.
Do I really need a consultation and prescription first?
Yes. A penile implant is permanent surgery, and it is only appropriate after a urologist confirms the cause of your erectile dysfunction, rules out simpler treatments and active infection, and checks that you are medically fit. The device is prescription-only and individually sized to your anatomy. The consultation is also where you receive an accurate, itemised price and discuss whether the LGX or another option suits you best.
