There are many reasons why a man may want to increase the volume of his semen. Many men seek out supplements to improve sperm production to boost fertility; others take them for the sake of having larger loads and better sexual gratification.
Semenex is specifically designed to increase semen production and help men experience more intense orgasms.
Here’s everything you need to know about Semenax — including how it works, what’s inside, and where to buy some yourself.
What is Semenax?
Semenax is a natural health supplement formulated to promote sperm production in men. It consists of various herbal and nutritional ingredients to provide the body with all the raw materials it needs to manufacture sperm cells and seminal fluid.
This supplement is also suggested to heighten the level of pleasure achieved during orgasm and prolong the duration of erections.
Semenax is made by Leading Edge Health, which is also the force behind VigRX Plus, one of the most popular natural options for managing erectile dysfunction.
What Are the Benefits of Semenax?
- Increased semen production
- Longer orgasms
- Greater pleasure
Does Semenax Work?
Semenax has never been formally tested to prove its efficacy. While many of the ingredients in the formula have shown dramatic benefits on sperm count, sperm morphology, and sperm motility, there is no proof these effects translate into this product without proper scientific testing.
With that said, there have been numerous anecdotal reports of users diagnosed with low sperm counts who have successfully used this supplement (along with other important lifestyle changes), and noted a dramatic improvement in sperm count.
It’s more than likely that this supplement, when combined with other measures like quitting smoking, eating a balanced diet, managing stress, and regular exercise, will work to increase your sperm count and overall sperm quality.
What is Semen Made From?
Semen and sperm aren’t the same things. Sperm is a single cell produced in the testes that carries half the genetic information of a human. The genes in the sperm cell mix with genes in an egg to complete the genome and create a human.
Sperm is just one component of semen, the fluid largely produced by the prostate that adds volume to the sperm and provides a fluid rich in nutrients and protective agents to give the sperm a better chance of reaching and fertilizing an egg.
Semen also contains elements that neutralize the acidity of the vagina and adds lubrication to the urethra walls of the penis to ensure all the semen passes through intact.
Semen is a complex fluid consisting of several different elements:
- Fatty acids
- Sperm cells
- Vitamin B12
- Vitamin C
How is Semen Made?
Semen is made through the combined effort of the prostate (seminal fluid) and the testes (sperm). It can take up to 5 weeks to produce each sperm cell, but the male body is constantly manufacturing these cells.
Healthy men produce around 1500 sperm cells every second of every day. A single ejaculation contains between 200 and 500 million sperm cells in 1 – 5 mL of fluid.
Sperm is produced in the testicles in a complex structure called the seminiferous tubules. Testosterone stimulates these tube-like structures to produce sperm from nonspecific cells called germ cells.
Once the sperm cells are complete, they use a tail on the back to move them through another section called the epididymis. This process takes up to 5 weeks to complete, eventually reaching another structure called the vas defferens. The sperm is then stored here until it’s needed during ejaculation.
During ejaculation, the sperm cells stored in the vas deferens are mixed with seminal fluid from the prostate and ejected out of the penis through the urethra with the hemp of a concerted muscle action in the perineum.
How Much Sperm is Considered Healthy?
The sperm count can vary from one man to another. A low sperm count is diagnosed when there are less than 15 million sperm cells per milliliter of semen. The normal range is between 15 million and 200 million sperm cells per milliliter.
Anything over 300 million sperm cells per milliliter is considered high.
What Are the Causes of a Low Sperm Count?
Low sperm (oligospermia) can have many different causes.
Just a few examples of causes for low sperm counts include:
- Age (sperm counts decline naturally with age)
- Alcohol, nicotine, or drug use
- Chronic stress or anxiety
- Depression or mood disorders
- Exposure to certain chemicals or toxins
- Exposure to radiation (may cause damage to the testes)
- Poor nutrition (lack of nutrients needed to make sperm)
Sperm Morphology & Motility Is Important Too
When you go for a sperm analysis, you’ll get results for the sperm count, as well as two other key factors:
A) Sperm Morphology
Sperm morphology refers to the shape of sperm cells. The total sperm count may be normal, but if the sperm cells are misshapen or are too large or too small in size, it’s going to negatively affect your fertility just as much as a low sperm count.
The ideal range for sperm motility is 4 – 48 percent with optimal size and shape, according to the World Health Organization.
B) Sperm Motility
Sperm motility measures the ability of a sperm cell to move around. Sperm needs to actively find an egg to fertilize and requires the ability to move and maneuver around to find its match.
Poor sperm motility (asthenospermia or asthenozoospermia) is considered when a sperm cell cannot move at least 25 micrometers per second.
Sperm can suffer from slow or sluggish movement, unproductive movement, or no mobility at all — all three will have a dramatic negative impact on fertility.
How is Low Sperm Count Diagnosed?
You won’t be able to tell if your sperm count is down by yourself. Most people notice while trying to conceive after a woman cannot get pregnant after several months of trying for a baby. Tests should be done on the man and the woman to assess fertility.
For men, the test involves a simple semen analysis. A sample of semen is tested to obtain the sperm count, mobility of the sperm, and morphology of the sperm.
Reference Ranges for Sperm Analysis
|Sperm Quality Metric||Minimum Threshold||Average|
|Sperm Count (Measured in million per mL)||15 million per mL||15 – 200 million per mL|
|Sperm Morphology (Measured in percent within optimal size and shape range)||<4%||4% – 48%|
|Sperm Motility (Measured in percent with more than 25 nm per second movement)||<32%||32% – 75%|

What Are the Ingredients of Semenax?
- Catuaba Bark
- Epimedium Leaf
- Hawthorn Berry
- Muira Puama
- Pine Bark Extract
- Pumpkin Seed
- Swedish Pollen Flower
- Vitamin E
- Wild Oat Straw
- Zinc Oxide
1. Catuaba Bark
Catuaba is a male sexual potency herb from the Amazon rainforest. In this region of the world, there is a saying, “until a father reaches 60, the son is his — after that, the son is Catuabas!”
This is an ode to the powerful fertility-enhancing effects of catuaba bark, especially in older men.
A large part of this improvement in fertility comes from catuabas ability to improve erections, but it may also play a role in the production of sperm and semen through the herb’s interaction with dopamine receptors.
Studies have shown that dopamine receptors can be found in the male genital tract and spermatozoa — which suggests dopamine is an essential regulator in producing sperm and other seminal fluids in humans .
Cranberry isn’t added into this formula to directly boost seminal fluid. Cranberry extract contains a compound called D-mannose — a particular type of sugar that passes through the kidneys intact. It enters the urinary tract, where it exerts its benefits.
D-mannose is useful for cleaning out harmful bacteria from the urethra by interfering with their ability to attach themselves to the urethra walls.
This has an indirect benefit on sperm count by reducing the oxidative damage sperm cells are exposed to as they travel through the urethra.
3. Epimedium Leaf
Epimedium, also known as “horny goat’s weed,” is one of the most well-known aphrodisiacs and male sexual performance enhancers in the plant kingdom. It contains a compound called icariin, which works similarly to prescription erectile dysfunction medications like Viagra, Cialis, or Levitra.
Epimedium and its active ingredient, icariin, inhibit an enzyme known as PDE5 (phosphodiesterase type 5) . Blocking this enzyme leads to stronger, fuller, and longer-lasting erections.
Icariin has also been shown to mimic the effects of testosterone , which is critically important for regulating semen production, libido, and erectile function.
4. Hawthorn Berry
Hawthorn is used in herbal medicine for treating and preventing heart disease. It improves the contractile force of each heartbeat, widens the coronary arteries, and dilates blood vessels around the body.
Improving the health of the cardiovascular system has a major impact on erectile function in men. One of the core signs of a healthy cardiovascular system is a strong, healthy erection, especially in the morning.
L-arginine is an amino acid that produces hundreds of individual proteins and enzymes in the human body.
This amino acid also serves as the base molecule for nitric oxide (NO)  — a chemical messenger used to initiate the dilation of the arteries in the penis leading to the formation of an erection.
The concept behind taking L-arginine for male sexual performance is to ensure the body has access to all the raw materials needed to function optimally. If the body needs to make NO to stimulate an erection, but there isn’t enough L-arginine to produce this compound, it may be difficult to achieve or maintain a full erection.
L-carnitine, like most amino acids, has a lot of different uses in the human body. One of the most important has to do with the production of energy inside the cells. L-carnitine serves as a transporter to allow fatty acids to enter the mitochondria, where they can be broken apart and used for energy.
This effect is especially important in the testes during sperm production  — which itself is a very energy-intensive process.
L-lysine is another amino acid with connections to sperm production. It’s believed L-lysine supplementation can improve overall sperm count and sperm motility, and some reports even suggest this amino acid can support the production of testosterone.
The research in this area is significantly lacking, with only in vitro and animal studies currently available to support these claims. One study found that L-lysine had a protective effect on the semen of bulls after freezing — maintaining a high degree of fertility after being exposed to cryogenic environments .
Maca is a popular fertility-enhancing supplement due to the herb’s impressive nutritional profile. It’s especially high in the amino acids arginine and histidine — both of which play an essential role in male reproductive health.
This herb also offers adaptogenic benefits — a term used to describe compounds that increase the body’s natural ability to resist stress. Chronic stress is one of the leading causes of reduced testosterone levels, low sperm count, and poor libido.
The only downside to this addition in the Semenax formula is that maca only works when you take high concentrations of the herb over long periods. It’s unlikely the maca in this formula offers many benefits to the formula.
9. Muira Puama
Muira puama is often used alongside another herb in this formula — catuaba. Both trees can be found growing in the dense Amazon jungle. The bark of these two plants is infused in water overnight and drunk throughout the next day.
A proprietary formulation containing muira puama and catuaba — called Catuama® — has been shown to offer direct vasodilating effects to increase the firmness and longevity of an erection in older men .
10. Pine Bark Extract
Pine bark contains a compound called pycnogenol, which has been shown to improve sperm morphology to improve overall fertility in men . It also contains a powerful array of antioxidants that may help slow the degeneration of sperm cells in the semen during ejaculation.
11. Pumpkin Seed
Pumpkin seed extracts offer two separate benefits in terms of male reproductive health.
It’s rich in zinc, which is one of the most impactful trace elements involved in male reproductive health. Zinc is required for cell division, which is a key element in sperm cell production. It’s also required for testosterone production, which acts as the primary regulator for semen production.
Pumpkin seed provides a rich source of omega-3 fatty acids — which the body uses to create prostaglandins. Many of these prostaglandins act as regulators for male sexual function.
Sarsaparilla is often used by bodybuilders as a natural anabolic steroid — however, these effects have never been supported in medical research.
This herb has never been confirmed to offer any benefit on male hormone levels, but it does provide a rich source of amino acids and antioxidants that may be useful for supporting healthy reproductive function.
13. Swedish Pollen Flower
This is one of the primary ingredients in Semenax. It’s used to maintain the health of the prostate  — which is the source of seminal fluid.
This supplement is especially useful if there’s a problem with the prostate, but will offer supportive benefits on the production of seminal fluid in healthy men as well.
14. Vitamin E
Vitamin E is an antioxidant and natural preservative. It’s likely added to prevent the oxidation and breakdown of other ingredients in the Semenax formula, but could offer its own protective effects on semen quality as well.
15. Wild Oat Straw
Wild oat straw is rich in antioxidants and other protective phytochemicals. It’s traditionally used to promote heightened sexual awareness and increased sexual thoughts. They contain a group of compounds known as saponins, which act as regulators for various hormones in the human body — including both testosterone and estrogen in men.
Zinc is one of the most important nutritional supplements for male reproductive health overall. This trace mineral is required for cell division to occur. During sperm production, cells are rapidly dividing, which results in a higher demand for the intake of zinc from the diet.
The recommended daily intake for zinc is 27% higher for men than it is for women to account for this.
Zinc is also an important element in the production of testosterone.
Semenax isn’t the only natural health supplement designed to increase sperm count and sexual satisfaction. There are hundreds of them.
The problem is that most of these supplements are ineffective or blatant scams.
Here are a few viable alternatives to Semanax that actually work:
- Conception XR
- Maca Concentrate (Lepidium meyenii)
- Ashwagandha KSM-66® Extract (Withania somifera)
- Ginseng (Panax ginseng)
Lifestyle Changes That Promote Semen Production
Lifestyle changes will have the biggest impact on semen production and quality overall.
Even if you’re using supplements like Semenax to boost your semen production, it’s important to take other measures to improve fertility. This involves reducing the cause of the low sperm count (such as smoking, alcohol, or stress) and ensuring your body has all the building blocks it needs to manufacture semen effectively.
A few examples include:
- Exercise regularly
- Maintain a healthy weight
- Limit exposure to cell phones (avoid keeping your cell phone near your testes)
- Reduce or eliminate alcohol intake
- Quit smoking
- Avoid exposure to toxic chemicals
- Drink plenty of water
- Eat a healthy diet rich in fruits and vegetables
