Sizegenetics In-Depth Review and Results [UPDATED]

In this article, I review the Sizegenetics penis extender. Male enhancement products promise to increase your penis size. However, most of them fall short. However, Sizegenetics is different.

About Sizegenetics

Sizegenetics can be worn under loose clothing for extended periods of time. And it’s easy to carry on with your daily activities. Nobody will know you’re wearing it. This is important, since the more you use it the better your results. In one sense, using a penis extender is a bit like working out. As the extender stretches your penile tissue, it effectively breaks it down and causes it to grow.

How It Works

Traction is the principle that propels SizeGenetics. It makes it possible for tissue cells in your phallus to tear and grow into new tissue cells. Constant traction leads to permanent results over time.

When these gaps are created, cells divide and multiply. Your penis shaft and chambers then grow within the penis. Your penis now has more blood pumping through it. It becomes permanently larger.

As a result, your penis hangs lower when it’s flaccid. The growth is slow and gradual but it works. Guys are more confident in the bedroom. In addition, SizeGenetics is comfortable to wear.

You can wear it all day, even at work. Nobody likes the idea of doing permanent damage to the penis. Fortunately, it comes with a safety release to easily disengage. The 16-way comfort system makes it easy to provide the appropriate angle that’s most comfortable.

Sizegenetics Ultimate System

Sizegenetics Ultimate SystemThe Ultimate System is more comfortable and has more ways to secure around your penis. You get additional extension bars so you can add more as you grow.

The quarter inch bars are the most useful because they help the most when transitioning to the next set.

Overall, the Ultimate System is worth it. And it’s become a best-seller. I like the included training DVD, travel case, extra rods and penile exercise videos. As well as the three different fasteners to secure your penis instead of a one-size-fits-all approach.

While it’s not cheap, quality extenders cost more and require a commitment to achieve the full results. The more you put in the more you will get out.

Putting it on is easy.

  • Place the white base ring on your penis. This is the part of the extender that has the elongation bars.
  • Adjust the elongations bars to a  minimum of 1cm longer than your flaccid penis length.
  • Push the tip of the SizeGenetics device into the elongations bars.
  • Put the tip of your penis into the device.
  • Make the rubber strap tighter to ensure it holds firmly against your penis.
  • The lip of the device should fit beneath your penis glans. Gradually adjust the elongation bars to boost the tension force. However, if you are a beginner, wait a few weeks before doing this.

 Comfort Package

Sizegenetics Comfort PackageThis is my favorite package. It comes with the extender base, spare rods, and a discreet traveling case. As well as an instructional DVD.

There’s also a velcro strap, rubber noose, and comfort band. This gives you plenty of configuration options.

It’s also $50 cheaper than the Ultimate System while giving you the exact same results. And it’s a durable product that uses medical grade materials for maximum comfort and safety.

Value Edition

Sizegenetics Value EditionIt comes with the bare essentials such as the extender, rods, and straps to secure your penis. And there’s also an instructional DVD. If you’re on a budget and want to try penis enlargement this is a good package.

Or, if you feel more committed, try the  Premium System since it comes with spare parts and accessories.

You will get the same results as the Ultimate System. The only difference is the number of accessories you get. Both offers work well.

First Impressions

It was early in the morning when my package arrived, and I was preparing for work. I was so impatient to do something about my small dick that I  had to try it on immediately.  It was incredibly easy to wear.  I had planned to try it out, then take it off before I went to work.

But it was so comfortable that I decided to keep it on all day. I took the travel bag so that I could take it off and put it away. The only thing I had to do was wear looser trousers.

I didn’t need to take my SizeGenetics off for the entire day at work.  I was really amazed.  Of course, I was aware of it for the first few hours.  But it wasn’t really any kind of discomfort, just the feeling of pressure and tension that I wasn’t used to.  That afternoon I was in a really important meeting for about three hours.

And when it finished I realized to my amazement that I hadn’t thought about the extender on my dick.  This was a real surprise to me.  I had expected a certain degree of discomfort and was prepared to endure that for the sake of penis enlargement. But it appeared that the device wasn’t going to be uncomfortable at all.

That pretty much set the pattern for me for a while. I would wear it all work all day. The only drawback was that I couldn’t wear tight trousers.  Then, after a while, I decided to try wearing it while I slept.  This turned out to be easy.  Some guys report that they can’t wear the SizeGenetics device in bed. It keeps them awake but I was lucky not to have that problem.


Of course, for the first few weeks, I was rushing home to get the tape measure out every day.  Sometimes even twice a day, to see if there was any gain yet.  Of course, there wasn’t, not for the first few weeks.  After three weeks I noticed my penis felt a little fuller. It felt heavier.  A couple of weeks after that I could see the first gains in length.

And at the end of six weeks, my tape measure showed I gained half an inch in length.  I can’t tell you how excited I was.

The other thing I noticed was that my erections were harder. I discovered that it was possible to have much harder erections than I’d ever experienced. Of course, as a 28-year-old virgin, I was an almost obsessive masturbator. And I noticed around this time that my ejaculations were much more forceful. And my orgasms would actually last longer. I was nearly dying of pleasure sometimes because I was coming so hard.

Sizegenetics comes with a wide range of settings with their 16-way comfort system. It provides one of the most comfortable fits you can have. Just dial things in to easily get enough force on your penis without feeling discomfort.

Sizegenetics vs Phallosan Forte

PhallosanBoth are length devices. They work in the same way by stretching your dick for prolonged periods of time. But I’d like to address the comfort and ease of use. I found Phallosan to be a little more comfortable.

But it doesn’t mean you can’t wear Sizegenetics for 7-8 hours a day. You just have to set it upright. In fact, I’ve made more gains with Sizegenetics since I’ve used it more.

While Phallosan is slightly more comfortable I found Sizegentics easier to use. It’s as simple as removing the strap. It’s something to consider if you tend to pee a lot. I’ve used my Sizegenetics for about a year longer than I used Phallosan.

And it’s much easier to take off. I can do this in 2 seconds and literally put it on in 8 seconds. With Phallosan it can take me 30 seconds.

The reason it takes longer is that it’s it uses condom sleeves. Although it makes it comfortable you have to be careful. Putting it on and taking it off can cause rips. And they’re expensive since they’re customized. So please be careful. With Sizegenetics I don’t have to worry since there’s nothing to tear.

Sizegenetics vs Bathmate

BathmateComparing Sizegenetics to the Bathmate is like comparing apples to oranges. Bathmate is a girth device that you use for 5-10 minutes a day. Whereas Sizegenetics is a length device that you wear for 7-8 hours per day 6 days per week.

The second thing to bear in mind is how fun they are. I consider Bathmate a “sexy” device because it’s fun to wear and feels good on your dick. It gives you instantaneous yet temporary results that eventually become permanent.

After 10 minutes of use, your dick will become thicker and longer than it’s ever been. You can take your increases size immediately into the bedroom.

Sizegenetics is not as fun to use. You have to wear it all day for 6 days a week. And you don’t get the immediate pump effect like you do with a Bathmate.

Frequently Asked Questions

Here are answers to some of the most common questions.

Is There a Maximum or Minimum Size?

The answer is no but there are a few things to consider. If you’re above 6 inches, whether or not you have done male enhancement, then go with Sizegenetics. It definitely fits a 6-inch dick better than a 5-inch dick. If you’re under 6, I suggest  X4 Labs or Phallosan Forte. You can also do manual stretching if your penis is 6 inches and your new to male enhancement.

Sizegenetics work better for guys who have average or above average cocks (6 inches or greater).

If you are new to male enhancement you can gain up to an inch within 6-8 months. However, you’ll need to wear the device for 6-8 hours a day, 6 days a week. I know this from personal experience, feedback on penis enlargement forums, and recommendations by the manufacturer.

Noobies will get the best gains if they are new to penis enlargement. Here is the most important thing you need to know. The more you wear it the more you will grow. Keep this in mind especially on days when you don’t want to wear it.

Why Is Sizegenetics Not a “Sexy” Device?

Sizegenetics isn’t fun to use but it’s tolerable which makes it good. My idea of a sexy device would be the Bathmate or Penement Pump. They’re enjoyable to use and feel good on your dick. They’re quick, easy to use, and produce instant results that later become permanent.

If you’re using Sizegenetics correctly than you should have it on your dick for 8 hours a day. The reason I say it’s not fun is that you don’t see the gains right away. There’s a reason why I recommend this device. And why I think it’s one of the best for long-term permanent gains. If you can deal with wearing it all day for the next 6 months it will be worth the wait.

Furthermore, they’ve been used in clinical studies and they are certified as medical devices. And while penis pumps are more fun, penis extenders beat them when it comes to length.

Can I Use it if I’m Uncircumcised?

Yes, just move your foreskin out of the way.

Can I Wear Sizegenetics to Sleep?

I asked this exact question to Sizegenetics a few years back. They basically said if you do, be careful and put it on with the lowest possible tension. In case, you accidentally roll over and constrict the blood flow, which causes your dick to get cold. Do those hours add up? Possibly, since the tension is much lower. If you do decide to wear it make sure you’re sleeping on your back.

And, if you really want to use it at night I would consider using the Phallosan Forte. It’s more comfortable and safer.

Do I Need to Manually Stretch or Jelq?

I’ve had a lot of guys ask if wearing Sizegenetics is a complete substitute for manual stretching and jelqing. This involves stretching your dick with your hands which can be a tedious task. The answer is yes if you are new to penis enlargement.

Does It Increase Length?

Yes, by using the principle of traction.

Does It Increase Girth?

Unfortunately, no. If you want to increase girth you’re better off doing kegals or using a penis pump such as the Bathmate. Sizegentics is a length device.

Is It Safe?

2800 grams of tension is the force used for optimum results. While this may sound like a huge amount of pull, it’s relatively safe. Tests have been conducted to guarantee your safety and comfort and I never had a problem. SizeGentics has been around for a long time and has invested considerable research into their products. Quality control and medical grade materials prevent any discomfort from wearing it.

Can You Travel With It?

Yes, you can travel it but I wouldn’t wear it at the airport.You might set something off an alarm. And don’t wear it through security. Instead, wear it on the plane and put it on in the bathroom. This brings me to the next question. How do you travel with it?

If you have the full set it comes in a box which can be locked with a key. However, don’t lock it if you’re storing it in your suitcase. TSA will try to open it. Even better, if you have the Bathmate carrying case you can store it in there.

What About Fake Reviews?

A lot of companies display fake user testimonials as a way to advertise their products. This is why you should learn how to spot them.  Use common sense and don’t believe anyone that promises quick results. Furthermore, if you’re shopping on Amazon, skip the reviews that are not labeled as verified purchases.

Money Back Guarantee and Warranties

It’s easy to purchase SizeGenetics via the company website or with select authorized global vendors. There are other companies that sell this product online. However, how do you know they want you a sell fake product? The best way to know that you’re buying the real thing is to buy it directly from the company website. This is my preferred way.


After four months I reached what I think of as my half-way point in my penis enlargement program. By this time I had gained a whole two inches in length. And it didn’t really seem to be slowing down.

I knew that sometime soon it would because most of the gain happens in the first few months. By this time I was also doing penis exercise regularly and I think that this helped with the gains.

If you have the money, desire, and commitment to put in the hours for penis enlargement then it’s worth the investment.

If you want significant results than you need to wear your Sizegenetics for 6-8 hours per day. Do this for 6 days a week. In fact, you’ll find the time commitment the same with any extender you wear.

If you’re a total noobie and wear it 12 hours a day you’ll gain an inch in 4-5 months. Instead of 6-8 months.

Hopefully, this motivates you on days you don’t want to wear it. It’s similar to resistance training, otherwise, know as weightlifting.

As you break down the tissue, it rebuilds itself and gets bigger. By the time you get to the second or third month you’ll know how your progress is going.
