Semenax delivers impressive results not only in enhancing semen volume but in other ways as well. Based on our testing and analysis, for men and couples hoping to improve the volume and function of semen as well as libido and the intensity of orgasms, we recommend giving it a try. Semenax contains healthful herbs and supplements that support men’s sexual health in ways that are verified in clinical studies. Though this isn’t its stated purpose, the active ingredients have been shown in studies to improve libido as well as sperm motility and sperm count (potentially helping couples conceive) and also to balance a man’s hormones so that men dealing with low testosterone feel more energy and vigor. Leading Edge Health is a company you can trust to deliver this product discreetly and with a high level of quality.

Human sexuality is one of the most complex subjects imaginable, with countless signals being sent voluntarily and involuntarily between lovers. But one moment in particular -- the moment of climax -- understandably grabs a lot of attention.

Along with the intensity of orgasms, many men and their partners see the volume of semen as very important. Sexual partners often see it as a signal of immense satisfaction (or dissatisfaction, if semen is scarce or if an orgasm is shorter and less intense). Many couples think of it almost like a component in the grand finale of a fireworks display. Men who produce a small amount of semen often feel insecure about it. Many others notice the quality and intensity of their orgasms are dwindling along with the amount of semen.

If this describes you, then you’re far from alone. Maybe it’s no surprise that Semenax, a company with “Semen” at the start of its name, understands your goals and attempts to offer a product that increases the volume of a man’s semen, boosting the intensity of orgasm and improving general sexual health and satisfaction. It’s wildly popular, but does it work? Are there other benefits or unwanted side effects? We subjected Semenax to testing and analysis in order to give you all the details.


Why you should trust us

Innerbody Research recently celebrated its 20-year anniversary online. Over the past two decades, we have helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

We extensively test each health service we review. We try our best to give you, our readers, an unbiased exploration of at-home health services, free of marketing jargon or gimmicks. We evaluate the service based on our adherence to quality, the latest medical evidence and health standards, and a simple question: would we buy the product or service ourselves if it weren’t part of our job, and would we recommend it to family and friends?

Additionally, like all health-related content on this website, this review of Semenax was thoroughly vetted by one or more members of our Medical Review Board for accuracy.

What is Semenax?

Semenax, by Leading Edge Health, is a highly popular semen volume enhancer. All men produce semen, but over time, various factors — age, environmental factors, and lifestyle choices — can adversely affect semen production. While the body can still produce the normal range (3-5ml) of semen, it often does not because of insufficient resources. If the body is given what it needs to produce more semen, then the semen volume will very likely increase as long as there is no underlying medical condition or prescription treatment regimen that’s having an adverse effect on semen production.

As a semen-enhancing supplement, Semenax is made from herbs and minerals that trigger the body's natural production of semen. Semenax includes a laundry list of ingredients known to help with semen production.

Fuller details are below for digging deeper.

Does Semenax work?

Yes, Semenax does work, as proven in clinical studies and as evidenced by a multitude of satisfied customers.

The world of male performance enhancement supplements is littered with big, false promises, so skepticism is definitely justifiable. While many supplements claim to increase semen volume and improve sexual health, too few of them work as promised because they either rely on ineffective ingredients or they use effective ingredients in the wrong quantities. And fewer still subject their product to a proper clinical trial.

Semenax clinical trials

Semenax sponsored a randomized, double-blind, and placebo-controlled clinical study to investigate the effectiveness of its semen volume enhancement. The results showed Semenax significantly boosted semen volume and orgasm intensity, in addition to erectile function. Many trial subjects saw a 20% or higher increase in semen volume.

Other studies supporting Semenax use

The formula of this supplement is guided by individual studies of numerous ingredients separately in clinical settings. Semenax combines these ingredients — mainly herbs and minerals — into one supplement. Just about every herb in the formulation has been shown in scientific studies to be beneficial for all-around sexual health and increasing semen volume. For instance, Maca root, L-carnitine, Swedish flower, and zinc have been extensively studied over the years.

  • Studies demonstrate that maca root, when used for weeks or months, significantly increases sperm volume, sperm count, and sperm motility. These studies also showed that maca root significantly improves libido, mild ED, and overall sexual well-being.
  • Studies show that L-carnitine improves sperm motility and chromatin quality, both of which are major factors in male fertility.
  • Zinc has been shown in studies to be vital in everything from sperm function to prostate health and male hormonal balance. A lack of sufficient zinc in clinical studies hurts the quality of semen.
  • Swedish flower pollen promotes improvement in prostate health, based on clinical studies.

When combined, these ingredients boost sperm production, promote male sexual health and robust libido, and can only help sperm quality as well, though Leading Edge Health doesn’t claim that men using Semenax will become more fertile.

How does Semenax work?

Semenax works by providing vital nutrients that the male reproductive system will need to produce more semen. It also helps to trigger semen production by slightly raising testosterone production and providing male hormonal balance. Testosterone is an essential hormone, without which producing semen wouldn't be possible.

As the body continues to absorb the supplement's nutrients, the increased semen production is triggered by having more testosterone. The body then uses the nutrients to increase semen volume. That's why many men may not notice much of a difference during the first few weeks of taking Semenax regularly.

Semenax price

It pays to buy larger supplies of Semenax; not only do results become clearer after several weeks of use, but also the price per day improves from roughly $2.67 (with the one-month shipment) to about $1.10 (with the yearlong purchase). Those are the default discounts the company offers.

  • 12-month supply (normally $960): $384 using INNERBODY60 -- you save 60%.

These prices are available if you purchase from the Semenax website using our coupon codes.

When can you expect to see results?

Semenax is a supplement based on natural ingredients. Unlike a drug, it does not work instantly. That's why men using the supplement will probably have to wait a few weeks before they start seeing positive changes in their semen quantity.

On the other hand, there do not seem to be any severe adverse effects associated with the long-term use of Semenax, though we still recommend that you speak with a doctor to make sure that it does not conflict with other medications you might be taking. It’s always a good idea to talk with your doctor if you’re adding a new supplement to your routine.

Every person is different, and so the time it takes to see results will vary. However, there are a few commonalities we and others have observed:

  • Generally, you should expect some progress after a few weeks. Full effects may not be achieved until after a couple or few months of use, so Semenax is a product that rewards patience.
  • Men who are producing less than 1ml of semen a day, usually seen as well below normal, may notice an increase sooner than many younger men producing near-normal levels. Even though nearly all men eventually see their semen quantity reaching normal levels at around the three-month mark, those with lower quantities of semen tend to notice results sooner.
  • Men on regular doses of Semenax reported that they experienced higher libido while taking it, in addition to seeing what some estimate to be around 3-4 ml of semen, which is within the normal range. We've also spoken to men who happily became expecting fathers (in some cases after a long time trying) and attribute their success to Semenax, even though Semenax isn't advertised as being a fertility supplement. Clinical studies do confirm that some of the ingredients in Semenax improve sperm motility and sperm count, which leads us to believe it's a welcome side effect.
  • On average, men will see a noticeable improvement in the amount of semen they produce during the second month. However, the supplement needs to be taken regularly. In addition, positive results can be further compounded when matched with a good diet and exercise program.

A look at Semenax's ingredients

Leading Edge Health (the manufacturer and seller of Semenax) provides its ingredients list in a transparent way to anyone who wants to know what the formula includes. We appreciate this level of transparency.

Semenax does not use any fillers. Its active ingredients work in multiple ways to improve a man’s sexual health and the robustness of semen.

Pumpkin seeds

Excellent for improving prostate health and consequently semen production.


One of the most researched amino acids. Various studies have shown that when combined with zinc, it is an effective semen volume booster and a potent testosterone booster.

Swedish flower

Part of traditional medicine since the 1300s, with modern studies showing that it positively impacts prostate health. Prostate issues can often lead to lower semen volume.

Epimedium sagittatum

Also known as horny goat weed, it’s responsible for increasing blood circulation, helping to facilitate healthier erections.

Zinc aspartate and oxide

Often prescribed by doctors as a supplement for men with various sexual issues. Studies over the years show that zinc isn't just a potent fertility booster, but it helps address various other male sexual issues.


A key ingredient for male sexual health, it promotes the production of semen, works as a test booster, and improves blood circulation, among other things.

Muira puama

A fixture in most traditional medicine, known for boosting libido and enabling better erections.

Maca root

Often used to help men get healthier erections. Generally, the root is available in capsule form for male sexual enhancement. However, it is essential to take it in the right quantities for it to be effective.


Many studies support the role of L-arginine in semen production. When absorbed by the body in enough quantities, it can increase semen production to above-normal levels.

Hawthorn berry

Studied extensively and known to improve circulation, which can help produce better erections, not to mention general benefits in heart health.

Pine bark extract

A healthy erection relies a great deal on the body's nitric oxide production. Pine bark extract ensures that the body produces enough of it for harder and lasting erections.

Is Semenax legit?

Manufactured and sold by Leading Edge Health, Semenax is totally legit, serving men for over a decade. Leading Edge Health provides excellent customer support, making it easy to reach someone if you have a question, need to return the product, or have an issue with your order. You can take advantage of a 67-day money-back guarantee if dissatisfied with Semenax. We contacted the company's support and found them extremely helpful and responsive, which is unfortunately rare in this industry.

Avoiding fake Semenax

In a way, Semenax is a victim of its own success, with numerous companies either trying to mimic the supplement's branding or outright copying it. Be careful and make sure you’re buying legit Semenax because fake Semenax could be deceptive, untrustworthy, and downright dangerous to consume.

The best way to avoid buying an imposter is to buy directly from the Semenax website.

How to take Semenax

The dosage for Semenax is four pills per day. You should take two pills at one time in the day, and then the other two pills later in the day. Set reminders for yourself, because the best results happen when you establish this consistent routine and don’t forget doses.

If you do forget to take pills, you shouldn’t try to compensate for it later by taking more of them; just focus on remembering your doses moving forward.

Some people see initial results begin after just a week, but most people require at least 2-3 weeks before noticing results. And the benefits tend to get better after a couple of months. So don’t give up immediately — after 1-3 months, your patience will likely be rewarded.

Who should take Semenax?

Anyone who produces less than 3ml of semen could benefit from Semenax. It is a supplement that can also help men who have low libido, aren't able to enjoy a firm erection, and may even be suffering from low testosterone. While Semenax doesn’t claim to be a testosterone booster, the benefit comes from the combined effects of the many ingredients that work together to balance male hormones. This is part of the reason why men feel often more energetic, clear, and positive after several months of taking Semenax.

If you think you may have low testosterone, you should have your blood tested. There are multiple at-home testosterone tests that provide accurate results. You can read about them all in our comprehensive guide, where you'll also find useful discount codes.

Men over 40 should invest in a daily dose of Semenax to improve their semen quality and quantity. If they are producing normal quantities of semen, Semenax will ensure that they continue to sustain, if not improve, it further. Plus, it will help prevent men from experiencing their testosterone crash which can come at just about any age after 40.

Is Semenax safe?

Semenax and its ingredients have been shown in clinical trials to be safe and acceptable for most men when used as directed. There aren’t any documented side effects or risks as long as you use as directed.

If you decide to use Semenax, we recommend that you share your plans with your doctor. It’s always a good idea to communicate these details anytime you are adding a new supplement to your routine. And if you suffer from blood pressure issues, heart problems, or diabetes, we recommend that you get your Semenax use approved by your doctor before you start taking the supplement, just so that you're always safe.

Final thoughts and purchasing recommendations

From our testing and analysis, Semenax is perhaps the best semen volume enhancing supplement available. Clinical studies confirm that its ingredients and formulation work.

On top of that, Semenax has the confidence and dedication not only to put its product to the test in a proper clinical study, but also to protect you with a 67-day money-back guarantee. You can return Semenax to Leading Edge Health and get your money back; the company does not put any conditions in place, which means that you can send back whatever you have left. The leniency of this return policy is frankly a testament to the effectiveness of the product.

For men who are stressed out about low semen quantity, low libido, and mediocre orgasms, we believe you should consider buying a 6-month supply of the supplement. Here’s why:

  • The money-back guarantee protects you just the same, as long as you make a determination about it within the 67-day return window
  • You can get 45% off your purchase using our coupon code: INNERBODY45
  • The fullest results often come after a couple of months using the product
