Semenax Review: Does it work for sperm function and libido?

If you’ve heard of Semenax, you may be curious if the herbal supplement can actually improve semen production, among other sex-enhancing promises aimed at men.

We’ve researched the claims to offer this comprehensive review, including a look at its ingredients and how likely the product is to work. While some men are okay with average performance in bed, you’d rather be exceptional.


You are looking to improve your sex life and shoot bigger loads.

Whether you have sexual health issues with sexual function or are just curious about male enhancement supplements, this Semenax review will help you make an informed buying decision.

In our modern world, high-quality enhancement products are easier to obtain than ever, but not all of them work well.

I’ll cover essential information to consider before you buy, followed by a review of this all-natural option for better sexual performance.

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

Along with the intensity of orgasms, many men and their partners find semen volume to be very important. Sexual partners often see it as a sign of immense satisfaction (or dissatisfaction, if semen is scarce or the orgasm is shorter and less intense).

Many couples consider it almost like a component of the grand finale of a fireworks display. Men who produce a small amount of semen often feel insecure about it. Many others notice that the quality and intensity of their orgasms decrease along with the amount of semen.

If this describes you, then you are far from alone. It is perhaps no surprise that Semenax, a company with “Semen” at the beginning of its name, understands your goals and attempts to offer a product that will increase the volume of a man’s semen, increase the intensity of orgasm, and improve health and fitness. overall sexual satisfaction.

It’s very popular, but does it work? Are there any other benefits or unwanted side effects? We put Semenax through our tests and analysis to bring you all the details.

In fact, diabetes is the most common cause of low semen volume. It may also be a side effect of certain medications you are taking, or it may develop from a urethral stricture – all of which Semenax and its ingredients do not address.

We are going to cover some other safer and more effective alternatives if you are concerned about decreased semen and sperm function.

What is Semenax?

Semenax is a supplement produced by a company called Leading Edge Health.

It is marketed as a “male wellness” product, or more specifically, as a semen-enhancing supplement.

Semenax Ingredients


Semenax is said to be formulated with a proprietary blend of natural amino acids and herbal concentrates from Europe, China and South America.

Dr. Jessica Yih, a urologist at The Ohio State University Wexner Medical Center, says that although some ingredients have been studied, with some limited evidence suggesting efficacy, the doses may be too low to be effective.

A 2018 study reported that zinc supplementation combined with weight training was helpful in increasing testosterone levels.

A 2015 study demonstrated that maca has properties to improve fertility in men.

However, both studies were small and more research is needed.

Along with zinc and maca, here are other ingredients in Semenax:

  • Swedish pollen flower
  • L-arginine HCL
  • L-lysine
  • epimedium leaf (better known as “horny goat weed”)
  • L-carnitine
  • catuaba bark
  • pumpkin seed
  • Vitamin E
  • pine bark extract
  • muira puama
  • hawthorn berries
  • blueberry
  • wild oat straw
  • sarsaparilla

Leading Edge Health (the maker and seller of Semenax) provides its ingredient list in a transparent manner to anyone who wants to know what’s in the formula. We appreciate this level of transparency.

Semenax pills does not use fillers. Its active ingredients work in multiple ways to improve a man’s sexual health and semen solidity.

Pumpkin seeds

Excellent for improving prostate health and consequently semen production.


One of the most researched amino acids. Several 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 13th century, with modern studies showing that it has a positive impact on prostate health. Prostate problems can often lead to a lower semen volume.

Epimedium sagittatum

Also known as horny goat weed, it is responsible for increasing blood circulation, which helps facilitate healthier erections.

Aspartate and zinc oxide

Often prescribed by doctors as a supplement for men with various sexual problems. Studies over the years show that zinc is not only a potent fertility booster, but helps address various other male sexual health issues.


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

muira puama

An accessory in most traditional medicine, known to increase libido and allow for better erections.

maca root

It is often used to help men have healthier erections. The root is generally available in capsule form for male sexual enhancement. However, it is essential to take it in the right amounts for it to be effective.


Many studies support the role of L-arginine in semen production. When absorbed by the body in sufficient amounts, it can increase semen production to higher than normal levels.


Extensively studied and known to improve circulation, which can help produce better erections, not to mention overall heart health benefits.

pine bark extract

A healthy erection is highly dependent on the body’s production of nitric oxide. Pine bark extract ensures that the body produces enough for harder and longer lasting erections.

How much does Semenax cost?

The price of Semenax varies, although a 1-month supply usually costs $59.95. The price of Semenax seems to go down per bottle if you buy more than one bottle at a time.

The manufacturer says that the product has a 67-day money-back guarantee.

Does Semenax work?

Semenax pills are not likely to be effective.

There are many anecdotal reports online about the product acting as some kind of miracle product. But, at this time, there are no studies or any research from credible sources to back up the brand’s claims.

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

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

Additionally, a 2020 study reported that only a quarter of these types of supplements have any research to back up their claims.

Lysine and L-arginine

You can see that lysine and L-arginine are some of the key ingredients driving the claims behind this supplement.

Although L-arginine has been studied as a possible treatment for erectile dysfunction (ED), no credible research supports the idea that lysine deficiency causes ED, or that L-lysine can increase penile volume.

Yih says there is also a lot of misinformation surrounding this product.

He explains that only 10% of semen is made up of spermatozoa, while the rest of the fluid comes from the prostate, urethral glands, and seminal vesicles.

“Even though more fluid is being produced from the prostate, urethra, and seminal vesicles, orgasmic intensity is probably not directly related to volume,” he says. “Actually, it has more to do with the person’s arousal level and the strength of their pelvic floor muscles.”

He also says that any supplement can have a significant placebo effect, as someone taking it is likely to start thinking more about sex and feel more confident, increasing their level of arousal.

Semenax Side Effects and Safety

At this time, we have not been able to find any side effects related to Semenax.

However, keep in mind that just because a supplement is “natural” does not mean it is safe.

A 2019 study reported that only a small number of herbal supplements have been thoroughly tested for toxicity or their potential to cause cancer.

Other 2019 study showed that some herbal and dietary supplements, such as those for weight loss and sexual enhancement, include chemicals that are not listed on the labels.

It’s a good idea to talk to a doctor before taking any herbal supplement. This is even more important if you are taking any medication.

Some herbal supplements can interact with medications or potentially make them less effective. Some supplements may interact with similar drug-metabolizing enzymes, inhibiting enzyme function and increasing the duration or intensity of the medication. This can be especially problematic in the case of medications, such as anticoagulants, since the blood can be much larger than expected, causing bleeding complications.

Reputation and opinions of the Semenax brand

Semenax is a supplement based on natural ingredients. Unlike a drug, it doesn’t work instantly. This is why men using the supplement will probably have to wait a few weeks before they start to see positive changes in semen quantity.

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

Everyone is different, so the time it takes to see results will vary. However, there are some commonalities that we and others have observed:

In general, you should expect some progress after a few weeks. Full effects may not be achieved until after a couple of months of use, so Semenax is a product that rewards patience.

Men who produce less than 1 ml of semen a day, which usually looks well below normal, may notice an increase sooner than many younger men who produce near-normal levels. Although almost all men eventually see their semen amounts reach normal levels around three months, those with lower semen amounts tend to notice results sooner.

Men taking regular doses of Semenax pills have reported experiencing increased libido while taking it, as well as seeing what some estimate to be around 3-4ml of semen, which is well within the normal range. We’ve also talked to men who have happily become fathers (in some cases after trying for a long time) and they attribute their success to Semenax, even though Semenax is not advertised as a fertility supplement. Clinical studies confirm that some of the ingredients in Semenax improve sperm count motility and count, which leads us to believe that this is 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 semen volume enhancing supplement must be taken regularly. Furthermore, the positive results can be further compounded when combined with a good diet and exercise program.

It does not appear that the brand has any warning letters from the Food and Drug Administration (FDA) or any active lawsuits at this time.

Semenax has a profile on Trustpilot – a third-party consumer review website – and feedback and reviews are generally positive. As of August 2022, Trust Pilot’s overall rating was 4.2 out of 5 stars.

Satisfied users often comment that the supplement increased the amount of semen, and many say they saw the positive effects in as little as 3 days. Others say that the product also lengthened their orgasms and increased their intensity.

Alternatives to Semenax

There are many alternatives that you can try to get the results you expect if you are buying a product like Semenax.

Here are some of Yih’s recommendations:

  • Think more actively about sex . Yih claims that this is the most natural way to increase libido. “Plan date nights, explore different ways to touch yourself or your partner…set the mood with romantic lighting and music, etc.” He says that spending more time in foreplay will stimulate the prostate, urethra, and seminal vesicles to secrete more fluid, leading to more semen production.
  • Increases the muscles of the pelvic floor. Yih suggests doing pelvic floor muscle exercises like kegels. “Kegels aren’t just for women. Men can do kegels to help improve their control over ejaculation, increase time to ejaculation (if they have premature ejaculation), and strengthen the intensity of their ejaculation.”
  • Consider taking prescription medications . There are a few options available, such as clomiphene and hCG. These increase testosterone levels, which can also improve erectile function and libido. Yih says it’s also important to note that while direct testosterone supplementation with testosterone gel or injections is good for improving erectile function and libido, it will actually stop your testicles from producing sperm count. The volume of your ejaculate may increase, but the number of sperm count will most likely decrease or stop being produced altogether. The following oral medications stimulate blood flow to your penis to help treat erectile dysfunction, if those are the symptoms you are also treating:
    • Avanafil (Stendra)
    • sildenafil (Viagra)
    • tadalafil (Cialis)
    • vardenafil (Levitra, Staxyn)
  • Consider taking certain vitamins. Yih says there is evidence that vitamins and antioxidant supplements can improve male fertility. “Infertile men have a higher concentration of free radicals in their semen compared to fertile men. Free radicals attack the membrane that surrounds sperm.”

When to see a doctor?

If you are concerned about the possibility of low sperm yield, erectile dysfunction, or another male reproductive system problem, it is important to speak to a doctor before trying any supplement like Semenax.

Although these products are marketed as “natural” compared to prescription medications drugs, this does not always mean that they are safe for everyone.

A doctor can also help you rule out underlying health problems that could be contributing to your male reproductive system problems.

Additionally, they can recommend medications or nutritional supplements that may be a more effective treatment for your needs and that do not interact with any other medications or supplements you are currently taking.

If you decide to try Semenax, it may be helpful to keep a log or journal of how you feel while using the product. Although there are no known side effects, see a doctor immediately if you experience unusual symptoms, such as abdominal pain or increased heart rate.

Semenax Frequently Asked Questions

Is Semenax safe?

Although Semenax’s parent company claims that the product does not cause any side effects, there are no studies to support this claim.

The product is produced by pharmaceutical manufacturers that comply with thecurrent good manufacturing practice (CGMP).

How long does Semenax take to work?

Depending on the brand, people can see results after taking Semenax for 2 weeks.

The company also makes a vague promise on the website, saying that after “2 to 3 months of supplementation, you are likely to experience significantly higher ejaculations.”

However, Semenax has not been scientifically proven to work.

Can I increase my sperm volume overnight?

No. Although sperm is produced daily, your body is constantly helping to regenerate sperm, a cycle known as spermatogenesis.

On average, it takes about 72 days for sperm to mature, which means it can take about 3 months for you to notice a difference in your overall sperm quality if you’re taking any new medications or supplements.

If you don’t see any difference despite new medications or lifestyle changes after this time, see a doctor. He can help rule out other underlying causes that could be interfering with sperm production.

Is Semenax legit?

Manufactured and sold by Leading Edge Health, Semenax is completely legit and has been serving men for over a decade. Leading Edge Health provides excellent customer service, making it easy to reach someone if you have a question, need to return product, or have a problem with your order. You can take advantage of a 67-day money-back guarantee if you are not satisfied with Semenax. We contacted the company’s support and found them extremely helpful and responsive, which is unfortunately rare in this industry.

Avoid Fake Semenax

In a way, Semenax is a victim of its own success, with numerous companies trying to imitate the brand of the supplement or simply copy it. Be careful and make sure you buy legitimate Semenax because fake Semenax could be misleading, unreliable, and downright dangerous to consume.

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

How to take Semenax?

The dose of Semenax is four semen volume pills a day. You should take two pills at a time in the day and then the other two pills later in the day. Set reminders for yourself, because the best results come when you establish this consistent routine and don’t forget your doses.

If you forget to take semen volume pills, you should not try to make up for it later by taking more of them; just focus on remembering your doses in the future.

Some people see initial results after just a week, but most people require at least 2-3 weeks before they notice results. And the benefits tend to improve after a couple of months. So don’t give up right away: after 1-3 months, your patience will likely be rewarded.

Who should take Semenax?

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

If you think you may have low testosterone, you should have a blood test. There are multiple home testosterone tests that provide accurate results. You can read about all of them in our complete guide, where you will also find useful discount codes.

Men over the age of 40 should invest in a daily dose of Semenax to improve the quality and quantity of their increase semen volume. If they are producing normal amounts of semen, Semenax will ensure that they continue to maintain it, if not improve it, then further. Plus, it will help prevent men from experiencing their testosterone dip, which can occur at any age after 40.

To carry out


Semenax is a supplement marketed to enhance ejaculations.

Although the product contains some known and useful ingredients, such as certain amino acids and vitamins, it is unlikely that this product will work as advertised. Furthermore, it can simply offer users a placebo effect.

There are other alternatives, such as erectile dysfunction medications and certain vitamins. There are other ways to improve your sex life, such as thinking more actively about sex and creating stimulating environments for it.

If you are thinking of taking Semenax, it is important to talk to your doctor first. Some herbal supplements can interact with medications.
