SizeGenetics® Penile Curvature & Peyronie's Edition - At-Home Medical Traction Device (FDA-Registered)
Your Member Enlargement System
Description
The complete at-home system for men correcting penile curvature and Peyronie's disease. The SizeGenetics Penile Curvature & Peyronie's Edition is an FDA-registered medical traction device that applies gentle, measured, directional tension to gradually straighten penile curvature — non-surgically, privately, at home.
Built on the SizeGenetics traction platform trusted by men for over 25 years, this edition ships with the full elongation-bar range and comfort accessories for the long, repeatable daily sessions curvature correction requires.
What penile curvature and Peyronie's actually are
Peyronie's disease is the formation of fibrous scar tissue (plaque) within the tunica albuginea, the elastic sheath surrounding the erectile chambers. That plaque is less elastic than healthy tissue, so the penis bends toward it during erection. Congenital curvature is similar in effect without the plaque. Both respond to sustained mechanical tension.
How traction therapy corrects curvature
Penile traction therapy applies a steady, comfortable stretch along the shaft. Sustained tension triggers mechanotransduction — the process by which cells convert mechanical load into biological remodeling. Chung & Brock (Therapeutic Advances in Urology, 2013) documented that mechanical traction drives "reorganization and remodelling of collagen fibres into uniform densely packed fibrils parallel to the axis of mechanical strain." The European Association of Urology (EAU) Guidelines on Penile Curvature (2023) recognise penile traction therapy as a conservative, non-surgical treatment option for Peyronie's disease — addressing both curvature and length.
Across 15+ peer-reviewed studies (1,000+ patients), penile traction therapy shows a ~27% mean curvature improvement:
- Levine et al. (Journal of Sexual Medicine, 2008) — pilot study, 10 Peyronie's patients, 2–8 hours/day for 6 months: 10°–45° curvature reduction (avg ~33%) plus 1.0–2.5 cm length gain. [ref]
- Gontero et al. (Journal of Sexual Medicine, 2009) — Phase II prospective study, 15 patients, 4–6 hours/day for 6 months; gains remained stable after the device was discontinued. [ref]
- Moncada et al. (BJU International, 2019) — controlled multicentre study, 93 patients across six university hospitals (47 treatment / 46 control): treatment group achieved a mean 31.2° curvature reduction (41.1% improvement) and 1.8 cm length gain over 12 weeks. [ref]
Typical timeline: measurable curvature reduction of 10–20° by months 3–6, building to 15–30° by months 6–9 with consistent wear.
Most patients notice initial curvature improvement within 3–6 months of consistent daily wear. Curvature exceeding 90°, or active/painful (acute-phase) Peyronie's, warrants urological evaluation before traction.

Frequently asked questions
How long until I see curvature improvement? Traction therapy is gradual. Published studies used 2–8 hours of daily wear over roughly 6 months (Levine 2008; Gontero 2009). Most men notice initial curvature improvement within 3–6 months of consistent daily use.
What degree of curvature can be treated at home? Mild-to-moderate curvature responds best to conservative traction; severe curvature or curvature with pain warrants a urologist's assessment first.
Traction vs surgery — which is right for me? Traction is non-invasive, reversible and low-risk but slower; surgery is faster but invasive with its own risks. Many men trial conservative traction before considering surgery.
Is it safe / does it hurt? Worn correctly at recommended tension it should feel like a firm stretch, not pain. Start low and build up. Stop and consult a professional if you experience pain, numbness or discoloration.
Can I use it for general straightening without Peyronie's? Yes — congenital curvature responds to the same directional traction.

TREATMENT
The SizeGenetics™ uses the traction method, which is the most natural way to increase size. But how does traction work? By applying a steady stretch to the shaft of the memeber over time, the tissue cells divide and multiply – a process called ‘cytokinesis’ – for an increase in both length and girth that lasts. Yes – the effects of the SizeGenetics™ are PERMANENT! The enlargement technique that SizeGenetics™ uses can be done discreetly at home, so nobody needs to know about your quest for self-improvement.
The SizeGenetics™ is designed in Denmark and uses only the finest quality materials. If you want to learn more about our different models, check out the brief overview of our portfolio below:
TRAINING SCHEDULE
Our six-week ‘Slow Start-Up Schedule’ is an ideal training program for first-time users to get used to the SizeGenetics™ device and traction method. The initial SizeGenetics™ training program gives your body time to adapt, by starting out with low traction and short periods of usage of the device.
Traction and duration of use are then gradually increased week by week. The start-up schedule is meant as a guideline – if you feel you can move forward faster than indicated, you can do so since the product is safe in any event. Once the desired results have been achieved, the enlargement program can simply be discontinued, and the results are permanent without adding any training.
BENEFITS/SIDE-EFFECTS
Your body is probably just fine. But why not add a little extra in size and be the bigger man, literally? We believe the boost in size from using the SizeGenetics™ will give you an overall lift in self-confidence, boost your love life, and therefore improve overall life satisfaction. We see male enhancement as just another way of taking care of your body, like going to the gym or eating healthily. So start your journey towards getting a bigger one today. The SizeGenetics™ enlarger is the original and best method of enlargement. And we’re proud to have over 20 years of experience in producing the best extenders and happy that we have over half a million satisfied customers.
Benefits:
- Increased permanent size
- Stronger/longer erections
- Can help premature ejaculation
- Straightening of curvature
Side effects: The SizeGenetics™ doesn’t have any side effects in a medical sense, but these are the issues to look out for:
- Soreness around the fixation area behind the glans
- Difficulty in getting the right traction
- Slipping of the memember head under traction
- Impatience – using too much traction too soon

Thank you so much :D
Thank you so much to the designers of this device, and also to the customer service team, you're all GREAT. My customer service guy, Arnold, he gave me perfect advice as to how to keep the glans in the device without choking it too hard, that was paramount in me even being able to wear the device indefinitely.
I do remove the device every 20 minutes of wearing, as the glans will get purple after 20 minutes of wearing, and I take 5 minute breaks. The rosy colour of the glans comes back instantly after releasing the silicone tube.
I use the no-slip black rubber mat directly onto the penis, on top of it the sponge sleeve and then the silicone tube, fully onto the sponge sleeve. In this setting, the glans doesn't slip out of the silicone tube anymore, stays in, always.
I'm very happy and I wish all of you happy stretching :)

This is actually one of the greatest inventions ever created. It gives guys an opportunity to add an extra few inches to their manhood. At first, I was a little skeptical about the comfort of the product, but after some research I learned that there are different ways to attach this device, so I give it a try and now I’m very pleased with the comfortability of this product. After trying different methods of attaching it to Bobby without being uncomfortable I feel that for me the most comfortable way to wear it It’s with the silicon tube and the comfort pad, Both together is super comfortable to use and I can wear it all day long with sometimes forgetting that I have it on. I know it’s going to be different with everybody but as long as you find different methods to wear comfortably all day long, you’ll be happy with the result. In the beginning you will pinch your skin a few times with your fingers trying to put it on and off, but you will get the hang of it and like they say this is not a sprint it’s a marathon and if you wear it a few hours every day getting some rest when you feel sore and you don’t quit and you keep on with the program you will be very happy with the results so if you are thinking about purchasing it, just do it. We only live so long and if you are not pleased with the size of your tool make a change, get on with the program and you will get bigger with this device. It’ll take time but you will get there.

I’ve tried various stretches, pumps, and exercises. I gained about 1.5” in length, but plateaued. I bought this to reach my goal of +2” to my unit during the pandemic. And I got it. My gains haven’t gone away 4 years later. I just got a replacement strap to see how much further I can grow. Def recommend the product, if you can wear it for hours daily.

An Honest Review - Just buy it
I think this is a great product with great results. The catch is obviously that you need to invest the time and be patient. I recommended this product to my best friend and encouraged him to buy it ASAP to start his journey which he did. The most important aspects I find are: 1. The ability to employ constant traction for extended periods of time. 2. The ability to conceal it and be discrete. 3. Easy length management through either additional bars or extension via device.You cannot go wrong and the R:R ratio is definitely in your favor using this device..

I got the Ultimate system, shipping came in a few days. Just starting using the device, there are no instructions given with the package, just a QR code to some video links. After watching them there are some things that are not explained very well, some parts and their uses, not explained at all.
The biggest thing is when tightening the strap, it's very easy to pinch one's skin on it. This is very painful so I'd highly recommend the comfort pad. These foam pads look like they would get worn down over time so I recommend getting extra. Even with the ultimate set they only give one. And they charge $20 for a set of 4 which is a bit of a rip off as I'm sure the foam is probably only a few cents but it's the right size. The more frugal out there could probably do something equivalate with a large foam pad and some scissors for under a dollar.
Second issue for me at least was getting it tight enough that it wouldn't slip off. The video explains to have the extension bars equal to the length of your flaccid penis but I'm a grower not a shower so my flaccid length is only 2 inches and the minimum length for the basic extension bars is 3 inches so I had to do some stretching and pulling while fully compressing the extension bars to get it on. This took me well over an hour of trying different things to get it to work.
Third issue, the strap for me even at the tightest setting, while it would grip my foreskin, my shaft would simply slide out as the extension bars tried to pull it so with the comfort pad I had to take a couple pieces of tissue fold them to add some additionally padding and girth so that the strap would be tight enough so that my penis would not slip out.
After all that though, it worked very nicely.
The videos recommend for the first week to do 1 hour sessions at 1200 grams of tension, this is contrary to others tension therapies I've seen that recommend 4-6 hour sessions at 600-800 grams to start off. So I just went with what I felt was a good tension and see how long I could comfortably maintain it, about a 1000g of tension. After about an hour with the strap super tight so it would stay, the head of my penis started getting cold and blue from lack of blood circulation so I took it off to take breaks and alternated like this after it warmed up a bit. None of this is explained in any of the videos so to side effect or things to watch out for or what to expect other than gains and benefits.
I'm currently taking a break as the ligaments around my groin feel very stretched like I did the splits, waiting for my body to adapt and adjust. I know use of this device is a marathon not a sprit so patience is needed.
It's only been a few days so obviously I don't have any measurable results yet but what is obvious is that the device can stretch out the area and over time this should lead to extra length so I'm hopeful as there is a body of medical studies about extension therapy working. But I treat it like a workout and include rest as my body signals for me to do so.

1st Month for those on the fence It's been a month and I am pleased with the results have been amazing, My routine only varies on the days that I work I try to do it for at least 6hrs and my days off at least 10hrs, for those that have peryones(curvature) the first thing you will notice is increase in girth that's probably due to the lack of muscle tissue that has not grown typically on the side where it curves, you'll notice how the trunk or shaft of your johnson is the first thing that gets thick and strong which will already prove to work wonders when you get to action time, so after 1 month of use it seems like my girth has increased significantly and my length probably has close to half inch, but the most glorious aspect of all of this is that my wife cannot stop screaming when I'm inside of her(I swear this is 100 percent truth, for those that believe in God you all know swearing is a big deal), I also made her cry (lol ) which was a bit confusing at first cause I thought she was going through pain but she kept kissing me and told me afterwards that those were tears of joy and that she is amazed of how strong she feels me down there.My main purpose with this review is to address those who are on the fence about getting this device specially those with Peryones: - The size, girth and strength of your johnson is in a crippled state because one side(typically the side where your johnson is curved towards) of it has not developed muscle tissue to be in its optimal state, hence it means that because of it you have a reduced girth and and length just by having Peryones WHICH IS NOT HOW IT WAS MEANT TO BE, believe me is the equivalent of having a muscle imbalance, so far this is the best way to fix that muscular imbalance on your johnson. - It might sting a little bit: For those that stretch regularly or do yoga you will understand how muscle tears work , in my case with Peryones it stings on the side where the tissue has not grown or developed and I have to take deep breaths or change my breathing patterns according to the gravity of the sting(it literallyfeelsas if needles are getting pulled out of the side where you have the Peryones), if the stings get too overwhelming I remove the device and I let it rest until the stinging stops to put it back on and complete my hrs , if you do yoga or stretch regularly you won't have a problem reading when to take it off and putting it back on, but just remember because you have peryones your experience will not be pain free ,Everytime you put on the device probably around the 3rd or 4th hr of wearing the device it will literally feel as if needles are being pulled out of the side where you have peryones, just be patient and breath accordingly cause it I'll be worth the effort. DO NOT HYPER EXTEND YOUR JOHNSON, GO SLOW WITH THE EXTENSION AND INCREASE LITTLE BY LITTLE. - If you you feel uncomfortable telling your partner about the device just tell her the following in your own words(for those with Peryones): Say you magically stumbled upon information that led you into deep research and you finally found out that you have an unnatural muscuĺar imbalance(which is not a lie) on your Johnson and that you are going to get it fixed with a device, say something that goes along those lines and she won't give you issues, in fact she'll love you more once she starts feeling you stronger, longer and girthier(typically after 1st month of use). In closing: feel happy that you found a way to give your Johnson a workout thats effective and that can be worn anywhere without being detected, my curvature has not yet improved too significantly but my length and specially my girth has, I guess once the muscle tissue becomes more balanced that's when Mr Johnson is gonna start getting straighter, at least it feels that way so far. THE MOST IMPORTANT THING IS TO TRY TO GET AT LEAST 6 HRS A DAY AND DO NOT HYPER EXTEND which is how I have been doing it . Trust me, you will not regret it .

It definitely works, but be patient and consistent to see results
I’ve been using it for about six months and gained around one inch so far, wearing it 5-6 days a week for around 3-5 hours a day. I keep track of my hours and measurements in a spreadsheet (so far 400 hours in) and take photos of measurements to remind myself how much progress I’ve made.
The size increase is definitely noticeable and has been a boost to my confidence. I’ve seen some increase in girth too. It also makes you harder and for longer since it stimulates blood flow, so in that sense I plan to continue using it even after reaching my length goal. I wish I discovered the device years ago.
The device itself is very well-made with good quality material as I haven’t had any issues with it or parts failing, etc. It still looks brand new even after a lot of use. It’s comfortable to wear too but takes some getting used to at first with putting it on and securing a good grip (a bit of talc powder helps too). I find it's best to wear if you're laying down.
I’ve also been impressed with the customer support I’ve received, having had to email a few times along the way with questions and asking for advice, and they always reply promptly and helpfully. The same person replies to my emails, so it’s nice having consistency since they are familiar with me as a customer.
My advice/tips for new users - follow the start-up programme, be patient and consistent, clean the device daily, keep track of your hours and take regular measurements. I use the silicone tube as a strap and find that every few months or so I need to order a new one since it will lose its tightness overtime due to stretching, but it’s inexpensive to buy.

In my experience, the Sizegenetics stretching device is comfortable, but only if you know how to make it comfortable. I am uncut, so not any other stretching device works for me; I have tried vacuum devices and those have been the worst for me because my foreskin gets in the way. With this stretcher device, I use the silicon strap and the protection pad and those work for me. In the past, I have wore this device for 400 hrs and it did elongated my penis a little bit, but when I stopped wearing the device, I lost those gains. I am wearing the device again (it's been three months) but to be honest I have not seen much gains, only a small bit.

To Those Who Are Serious About Growth,
My journey with size genetics started a few years ago after I had recovered from a minor surgery where I was put to sleep, and the surgeon attempted to catheterize me and couldn’t get the Catheter in because of stricture. He used a surgical rod to open the passageway through my penis and unknowingly tore up my Urethra, causing severe scar tissue. After months of healing and contraction of inner tissue, I had lost almost half of an inch in penis length.
A urologist friend recommended the Size Genetics device to me. After using the device for several months, not in a very disciplined manner, I had barely gained back 3/8 of an inch. I decided to do a comprehensive study of penis scar tissue healing and enlargement. The first thing that I did after thorough research was put together a disciplined plan. I learned from a sports surgeon friend that you must give the body the proper tools to heal and grow. I use the device an average of 4 ½ hours daily, sometimes 5 hours. After stretching, I take 1,000 mg (2 capsules) of “Mother Nature” CAMU CAMU vitamin C from organic fruit. I take three capsules of COSOSAMIN ASU Joint Health (promotes ligament healing and growth) and 1 Nature Made Multi. I drink a protein shake of at least 35 to 40 grams made with Ancient Nutrition Multi Collagen Protein.
I started the planned aggressive program the first week in December, and I have grown in length a little over one-half of an inch. When used properly and with the right nutrition, the device works. I couldn’t be more pleased.

Great results with consistent use – Highly recommended
I've been using SizeGenetics since November, and I can confidently say that it delivers results when used consistently. Over the past few months, I've noticed an increase of about 1 cm in length, and even my girth seems to have improved.
The device itself is well-made, and while it takes some time to adjust to wearing it comfortably, the results make it worth the effort.
Overall, if you're patient and committed, SizeGenetics can definitely help you achieve noticeable improvements.

This works. I wore the instrument 6 hrs a day the 1st year, removing it every hour to allow normal blood flow before continuing... I grew an inch the 1st year. Every year after, I have been wearing the instrument 3 hrs a day, every other day...and I have continued to grow a 1/4 inch every year...I am absolutely thrilled and I will keep growing my penis likely forever! These gains I made, are erection gains, not just soft growth and my erection has gotten thicker and stronger as well. I did not have a small penis to start, but I want a huge penis. I am 3 yrs into doing this now. I have replaced the working parts once every year and purchased the extensions as I have continued to grow and the orders have always come. When I was young I started exercising my body with the intention to grow a good looking strong phisyque and now growing my penis is just the same. Growing a good physique or your penis is very similar... consistent stimulation, good nutrition and proper time to heal in-between...and time...and you will continue to grow and change due to the stimulation...it is not magic... I am so glad to live in this time of excellent engineering...to be able to have this fun. Thank-you engineers responsible and Size Genetics for offering this affordably.

I was ready to see a doc about my curvature. I came across Size Genetics and I am glad I did. Patience and consistency are vital. Within 6 months use I could tell my member was straighter than it had ever been. Added bonus was that I also grew almost an inch in length and an extra inch in girth. Needless to say my wife is extremely happy with the results.

Time+Effort+Discipline = Big results for my Manhood
Works great but it requires time, patience and endurance, do not expect results in less than a month. I have been using it for more than a year since April 2023 now in combination with a pump and those 2 has done wonders.
It was hard to vet a grasp of it at the beginning and really weird because Hey you are venturing into the unknown...
Do not forget to get your diet and sleep on point and get a lot of protein and minerals intake to help it grow stronger.
I wish I had done this earlier because it give you a truly great ROI on your sex life and it is a mental boost as well. If you can grow your manhood what else can you do?
Most people are making funny jokes about penis length but are not doing anything to improve it nor do they think it is possible and you get laughed at for doing so.
They are those that do and make it happen and other who watch on the sidelines!

You have to believe, it works very well!
I have been dealing with Peyronie's disease for several years. I didn't want to go for surgery, I thought there must be another solution. I started looking and that's how I ended up with Sizegenetics. I was very skeptical at first about what they promised, regarding the increase in size but also about Peyronie's disease. However, I said I had to try, I had nothing to lose. The results were exceptional, from all points of view. The biggest problem was the psychological one, Peyronie's disease brings with it ED but also a decrease in size due to the decrease in the volume of blood circulating. Everything has changed since the beginning. I haven't treated Peyronie's yet but things have improved. And as for the increase in size, there is no doubt, it works. Just like it works in the case of ED.

The product the company offers works great for what it's intended for, takes some time getting used to but with the friendly how to video cuts the time in half. Be consistent, that is key to getting the desired results; if it seems like it's not working, keep at it, the wait is worth it. Follow instructions carefully for best results. Good luck!

Excellent quality
The design and engineering of this product is excellent. I have been using it for more than one year now, and I find the silicone tube noose fit me best. One tip would be to clean the tube every day with hot water and dishwasher soap, this will result in higher friction (more grip) which again makes it more comfortable. Before I did this the tube tended to slip slightly and that was uncomfortable.

The buying and shipping experience was streamlined. The item arrived on time an was shown on site. Customer service was prompt to respond every time I have contacted them. The results from using the stretcher are real but you have to put in the time. I have gained 1.5 cm over a little over a year period. I am a builder and can’t wear it during my working hours so I am putting in less daily time than ideal. The result are just slower than using the recommended amount.

lt does make me feel diferent and through my experience all girls love a big member , all the girlfriends l have had ever since l started dated girl were amazed at my member size and knowing girls they love to tell thier girlfriends that they going out with a guy who’s got a big member .My current girlfriend just loves it and always trying to get me hard wherever we are just so she can feel it.l guess this is the reason where l decided to buy the Sizegenetics, cos before buying it l measured at 8 inches long erect and 6 inches girth, my plan is to acheive another 2 inches erect and half an inch girth.l’m approaching my 3rd month and stretching is going very well, l have not measured yet but l noticed that girth wise its looking fatter and also my girlfriend has noticed something differant with her sayingits seems to be growing. So if my GF has noticed something going on then it confirms that the Sizegenetics must be working.

I was so close to booking myself into a clinic to add a few cm to my member but then I found this and wanted to try it before committing to the surgery which would be life changing. after 5 months of use I have completely changed the way I think about surgery and its the last thing on my mind, the Sizegenetics has really helped me with my makeing love performance and also the length of my member .

I have been using male-edge since April 2014 and happy to confirm that all is well and improving my peyronies condition month by month. Had a bend of 30 degrees when I started which is now 15 degrees, so delighted with the results. In addition, my flaccid length has increased by 2 cms. The peyronies is causing a problem with the erect length and strength of erection but I am sure over time this will improve. Happy to say that the device is extremely easy to use and once mastered, can be fitted in under a couple of minutes. I personally use the gauze provided and found this to be particularly comfortable with the strap. Although I originally purchased the product for my peyronie’s condition the added length has been an extremely welcome bonus. Delighted with your product, easy to use and very effective.Kindest regards
SizeGenetics™ PROVEN RESULTS- THE WENDY HURN STUDY
Wendy Hurn, a urology specialist at Bristol Royal Infirmary in the UK, conducted research into treating member retraction caused by Peyronie’s disease, using the same member traction method the SizeGenetics™ member enlarger uses. The study proved that member traction is a perfect alternative to surgery and is highly effective in not only increasing the size of the member, but straightening it for men who may be affected by member curvature and retraction.
The study was based on 22 men between 18-78 years old with Peyronie’s disease. The subjects were divided into two groups; one group of men with 12.5cm or less (stretched member ) and one group of men with over 12.5cm (stretched member ). All subjects wore a medically tested member enlarger for an average of 5 hours daily for 3 months. At the end of the treatment, Hurn recorded an average 0.8-2.3cm increase in member length and 20% reduction of member curvatures.
BJUI RESEARCH
PROVEN MEMBER ENLARGEMENT- BJUI RESEARCH
In April of 2011, the British Journal of Urology International (BJUI) published a scientific study, conducted by two Italian doctors from the University of Turin. They researched in the field of non-invasive member enlargement, identifying clinically and medically valid research that had already been published. The aim was to bring all of the research in the field together, to finally draw a conclusion as to which member enlargement methods could really be proven to give lasting member growth results.
WHAT'S KNOWN ON THE SUBJECT OF MEMBER ENLARGEMENT?
The below texts are extracts from the study, which show that the member traction method of member enlargement that Sizegenetics uses is the only proven method to give natural, safe and permanent growth to the member.
1,5 inch (3,8 cm) in 5 month
I’ve been using it 5 hours a day for the last five months. It was 5″ when I started – now it is 6.5″ and still growing. My erections are stronger, harder, longer lasting and my orgasms and ejaculations are now more intense. Very satisfied!
