Best Penile Implant Size Options Types & Complete Guide in 2025

For many men, size really matters! For those considering penile implants, nothing is more important than choosing the right implant size, and this is for a good reason.

After all, the implant size can greatly affect the overall satisfaction and comfort of the implant’s receiver. Here we should mention that achieving good results depends upon choosing a well-made, manufactured implant that can suit each patient.

Interestingly, penile implants are not a new thing at all. They were first introduced in the 1930s by Russian surgeons, and since then, they have branched into different forms and sizes.

2025 Best Penile Implants Types and sizes

A penile implant (or prosthesis) is a surgical device used to treat severe erectile dysfunction (ED) that does not respond to medications or other non-surgical treatments. In 2025, the most commonly used implants include the AMS 700 for ED and the Penuma implant for cosmetic girth enhancement. These devices are designed to fit a range of penile anatomies, providing a natural appearance, comfortable fit, and reliable function.

Penile implant sizes vary significantly. Standard options often range from L to 3XL, with XXL being among the most commonly selected sizes. Length options typically span 12 cm to 22+ cm, and diameter choices (e.g., 9.5 mm to 14 mm) are selected by the surgeon based on precise measurements to ensure proper fit. While inflatable ED implants restore rigidity, they are not primarily intended for size increase. Cosmetic implants like Penuma focus on girth enhancement and can also improve the visible flaccid length in some cases.

Reported before-and-after results from men with ED implants or Penuma implants show high satisfaction, with many patients noting noticeable increases in girth and improvements in overall appearance.

Penile Enlargement Implant

Almost each guy with erectile dysfunction can regain an erection with the use of prostheses, or penile implants. Indeed, the most frequent surgical treatment used to treat erectile problems is these penile implants. During the procedure, the penis is surgically and invasively implanted with implants. Your surgeon will insert two cylinders, a reservoir, and a pump into your body to create an inflated penile implant.

These cylinders are connected via tubes to a different reservoir located beneath the muscles of your stomach. There is fluid in the reservoir, and the whole system is also connected to a pump.

A study indicates that improvements in surgical technique, together with traction treatments and surgeries to raise perceived penile size, are easy ways to optimize penile length.

For men seeking not only erectile function but also size enhancement, some cosmetic penile implants can improve girth and flaccid length. This demonstrates how penile implants for length and best penile implant options can be considered depending on individual goals and anatomical needs.

Best Penile Implant for Length

When it comes to penile implants, there are three main variations that you can think about. Penile implants are produced as inflated prostheses in two and three pieces, as well as in a pliable form.
According to a study, males having an inflatable prosthesis are likely to witness a more significant length increase than those with a malleable implant.

If you choose this path, your doctor will assist you in choosing the ideal penile prosthesis based on your medical condition, manual dexterity, and past surgical procedures. Here are the main options available.

The best penile implant for length is the AMS 700 LGX. Its inflatable cylinders expand in both length (longitudinally) and girth (transversely) to help counter perceived shortening.

Other models, such as the AMS 700 CX and Coloplast Titan, focus primarily on rigidity while still offering some length customization. Meanwhile, the Penuma implant provides significant increases in girth and flaccid length through a silicone implant. However, the LGX is specifically engineered for length restoration, making it the preferred choice for men seeking the best penile implant for length.

Penile Implant Size Options

Penile implant size options vary by brand (e.g., AMS or Penuma) and type (malleable or inflatable). They come in various lengths (approximately 12–27 cm) and diameters (around 9.5–14+ mm). Some systems offer extendable tips, while inflatable implants can provide girth expansion for a more natural feel. The final size and fit are determined by the surgeon during surgery to ensure optimal results.

Common penile implant sizes include:

• Lengths: Ranging from shorter (around 12 cm) to longer (up to 27 cm), selected to match the patient’s natural stretched penile length.
  
• Diameters (Girth): Available in different widths (e.g., 9.5 mm, 11 mm, 13 mm, 14 mm), with some inflatable models significantly expanding girth.
  
• Extendable Tips: Certain malleable implants (like the Rigi10) include extenders to fine-tune both length and girth.

AMS Semi-Rigid Models for Penile Implant (2025)

Semi-rigid or malleable penile implants are often made of two penile rods implanted in the electrode chambers of the penis. These implants usually fall under the following brand names:

AMS Tactra

These implants come in 14-23 cm, 16-25 cm, and 18-27 cm variations with different diameters. AMS (American Medical Systems) offers these semi-rigid or malleable implants with different penile implant size options to accommodate different anatomical variations in men. In the past, people have called them “Boston Scientifics Tactras”.

AMS Spеctra

These implants provide additional implant size options including 12, 16, and 20 cm in length with different diameters. They also come with “real tip” extenders that can also help to increase the sizes.

AMS Inflatable Penile Implants 2025 Sizes

Inflatable penile implants are optimized for inflation and deflation for the sole purpose of simulating a more natural erection. You can find two main types of inflatable implants in the market: two-piece and three-piece systems. These types also include:

AMS Ambicor

The Ambicor 2-Piece is manufactured as a two-component system for optimal comfort and ease of use. You can find it in sizes of 14 cm, 16 cm, 18 cm, 20 cm, and even 22 cm lengths.

AMS 700™ LGX

The AMS 700 LGX penile implant is available in standard lengths of 12 cm, 15 cm, 18 cm, and 21 cm, suitable for both Penoscrotal (PS) and Infrapubic (IP) surgical approaches. These three-piece inflatable implants are designed to provide significant length and girth expansion, helping men preserve or regain penile size. Known for their durability, they offer a firm and natural-feeling erection when inflated.

AMS 700 CX

The AMS 700 CX similarly offers several penile implant-size options to the AMS 700 LGX. The implant achieves a firm erection by providing more rigidity and girth expansion. You can find it in sizes of 12 cm, 15cm, 18 cm, 21 cm, and even 24 cm.

AMS 700 CXR

The inflatable penile prosthesis is manufactured as an option for those with small implant needs and those with fibroids, deep scarring, or narrower organs. You can find it in sizes of 10 cm, 12 cm, 14 cm, and 16 cm, and 18 cm.

Things to Consider When Choosing Penile Implant Size

Together, you and your physician will choose which kind of implant is ideal for your particular case after carefully discussing all factors during your appointment.

Your surgeon should take into account your particular medical background and characteristics. This requires a thorough medical examination and testing. Among the factors that you need to consider when choosing the best penile implant are:

• Your penile size and worries about length loss
• Your general health state
• Your age (and the age of your partner)
• The total cost of the procedure (including consultation and maintenance)
• Prior abdominal and reproductive surgical procedures
• Your body type and the presence or absence of a noticeable suprapubic fat pad
• Whether a penis is circumcised or not

Penuma Penile Implant

The Penuma® implant is an FDA-approved penile implant made to make a penis seem and feel larger, and it has drawn increasing interest as a possibly safe method for men to enlarge their penis.

In this case, medical-grade silicone is used to make the soft penile implant (similar to butt and chin implants).
Enhancing a mans sexual experience and self-assurance in his sex life is the main goal of the implant.

Additionally, it seems to be supported by several sound scientific research. Indeed, the prosthetic implant can provide additional circumference, correct abnormalities, and enhance the appearance of a retractile penis.

It is implanted subcutaneously, which means that it is situated above the tissue that permits the penis to function but beneath the skin.

Penuma Implant Sizes

Penuma implants come in three main sizes—Large (L), Extra-Large (XL), and Extra-Extra-Large (XXL)—designed to increase girth and provide some improvement in flaccid length. The specific size is determined by your surgeon based on your anatomy to achieve natural-looking results, generally adding 1.5 to 2.5 inches in girth and length.

Before and After Penuma Size Chart

Studies and surgical data show the following average improvements:

• Girth (circumference): 1–2.5 inches (3.1–6.35 cm) increase
• Flaccid Length: 1.5–2.5 inches (3.8–6.35 cm) increase
• Erect Length: Typically no significant increase

Surgeons select the appropriate implant using patient measurements (flaccid length and girth) in combination with the Penuma implant size chart, which correlates flaccid dimensions with the suitable implant size and expected results.

Penile Implants Before-and-after results

Before-and-after experiences reported by men who undergo penile implant procedures—whether for ED treatment or cosmetic enhancement with devices like the Penuma—generally show high satisfaction rates. Many patients report noticeable increases in penile girth, commonly averaging 1 to 2 inches in circumference, as well as visible improvements in flaccid length of up to 1–2 inches. Beyond physical changes, patients frequently describe improved confidence, enhanced sexual performance, and a better overall quality of life.

Cost of Penile Implant Size Options

The cost of a penile implant isn’t cheap in most countries. However, in countries like Turkey, the cost is often cheaper than in other places, costing between $4000-$8000.

In the United States, the surgery can cost up to $20000, which is significantly high for many patients. The same thing can be said about the cost in Western and Northern Europe.

In the UK, prices are often $8,750 to $18,750, depending on the implant type (malleable being cheaper than inflatable) and bundled services.

The Penuma XXL implant cost varies but generally falls within the $15,000 to $24,000+ range in the US, covering the implant (around $5,000) and surgical fees.

However, patients are often shocked to hear that Medicare and the majority of large insurance companies could pay for penile implant surgery if deemed necessary.
