SEMENOLL The Best Male Fertility Supplement

Prevalence of Male Infertility

According to MayoClinic, “Nearly 1 in 7 couples is infertile. In up to half of these couples, male infertility plays at least a partial role.”

According to the US Department of Health and Human Services, “In one-third of infertile couples, the problem is with the man.”

Signs and Symptoms of Male Infertility

The main sign of male infertility is the inability to conceive a child. There may be no other obvious signs or symptoms. In some cases, however, an underlying problem such as an inherited disorder, hormonal imbalance, dilated veins around the testicle, or a condition that blocks the passage of sperm causes signs and symptoms.

According to Mayo Clinic, the following may be the signs and symptoms of male infertility:

  • Problems with sexual function — for example, difficulty with ejaculation or small volumes of fluid ejaculated, reduced sexual desire, or difficulty maintaining an erection (erectile dysfunction)
  • Pain, swelling, or a lump in the testicle area
  • Recurrent respiratory infections
  • Inability to smell
  • Gynecomastia — Abnormal breast growth in men
  • Decreased facial or body hair or other signs of a chromosomal or hormonal abnormality
  • A lower than normal sperm count — fewer than 15 million sperm per milliliter of semen or a total sperm count of less than 39 million per ejaculate

How Semenoll Supports Male Fertility and Sexual Performance?

Semenoll contains the right and proven 100% natural ingredients that treat all the possible causes of male infertility. Semenoll focuses on improving the testosterone levels in your body that results in improved sexual health and performance. Your semen and sperm quality, and quantity, both have an impact on your fertility. In the same way, erectile dysfunction, premature ejaculation, and the quality of your sexual quality have an invasive impact on your fertility.

Semenoll naturally maximizes your fertility, sperm count & sperm quality, and sexual performance with its triple-action ‘Semenoll-Effect.’ These three actions engage the core components of your sexual health and result in improved fertility and sexual performance. The overall result is a natural, safe, and non-invasive way to effectively improve your chances to reproduce while simultaneously boosting your performance in the bedroom! Here is a brief explanation of this triple-action ‘Semenoll Triple-Action Effect.’

#1. Enhancing Your Fertility

Semenoll enhances male fertility For male fertility purposes, the testosterone hormone plays a crucial role. Your male reproductive health and sexual function depend on Testosterone (T). Studies have proved that low testosterone is the major cause of reduced sperm count and infertility and low libido, and impotence. Such an invasive role of testosterone hormone on male infertility makes this hormone the real manhood hormone.

Semenoll contains 100% safe and proven ingredients that can boost your testosterone naturally. That results in good quality sperm production and improved fertility.

#2. Protecting Your Sperm

Semenoll protects sperms and improves sperms health and quality Increase your chances to reproduce by improving sperm parameters with potent antioxidants.

Do you know your sperms are extremely fragile? Oxidative stress (OS) is a common cause of sperm dysfunction. That includes low sperm count, defective sperm morphology, and low sperm motility. Think of oxidative stress as a toxic build-up in your body that results from years of unhealthy lifestyle and eating.

Oxidative stress specifically targets your sperm DNA. This causes a decline in the semen volume and the number of viable and healthy sperms. As a result, the number of dead or slow-moving sperms is increased in your semen, and it makes the process of egg fertilization near to impossible.

Semenoll naturally protects your sperm by giving your body the scientifically proven potent antioxidants essential to fight oxidative stress and sperm dysfunction.

#3. Improving Your Sexual Performance

Semenoll increases blood flow in vessels and improves sexual health Do you know your sexual health depends on a steady flow of oxygen-rich blood to the reproductive organs?

Sperm abnormalities have also been linked to circulatory problems. The decreased blood flow in your reproductive organ is also a common cause of erectile dysfunction. Increased blood flow in your reproductive organ not only supports good sexual health but can improve the size, strength, and intensity of your erections.

So you can protect your reproductive health while simultaneously boosting your performance in the bedroom. Making a baby should be fun, right? Semenoll naturally boosts blood circulation in your reproductive organ. As a result, Semenoll supports your sexual health and improves performance in the bedroom.

After knowing the ‘Semenoll Triple-Action Effect’ in this Semenoll review, let’s have a look at the miraculous ingredients of Semenoll that lead to magical fertility and sexual health results.

Semenoll Ingredients: Here’s The Secret How Miracles Happen

The clinically backed ingredients in Semenoll can naturally support and improve your body’s reproductive function, semen quality, and sexual performance. Rest assured that all the ingredients of Semenoll are 100% natural and safe. Semenoll does not contain any suspicious proprietary blend with unknown quantities of the ingredients. Each ingredient of Semenoll is included in the formula with its discrete quantity.

Let’s have a look at the roles and functions of Semenoll ingredients.

Maca Root Extract

Semenoll contains a massive 3,000 mg dose of Maca root extract – more than you will find in any other supplement.

Do you know why Maca root is an essential part of every male fertility supplement?

Because of its clinically-backed fertility-boosting properties in men, in recent research, when given to men for only 12 weeks, Maca root extract caused a 9% increase in semen volume, a 20% increment in sperm concentration, and a 21% rise in normal sperm in the semen. (1) This research used 1,750 mg Maca root extract per day. Thus, Semenoll contains almost twice the dose for your increased chances of successful conception!

Zinc Oxide

According to one study, 50% of infertile men have a zinc deficiency? (2)

Zinc is perhaps the most important mineral for male sexual health, and it’s a game-changing item for boosting male fertility.

Your sperms are highly fragile and sensitive. That’s why they don’t tolerate toxic environments. Zinc is a powerful antioxidant that protects your sperm. (3) This increases your sperms’ likelihood of survival; and fertilization. Also, as the most abundant nutrient in your semen, zinc is essential for healthy sperm quality. Studies found zinc supplementation to significantly increase semen volume and sperm motility. (4) Zinc also has a positive effect on your testosterone levels. It can give a boost to your hormonal health and, as a result, sexual performance.

N-Acetyl L-Cysteine

N-Acetyl L-Cysteine (NAC) is another of the best antioxidants that can do wonders for male fertility. In many research studies, NAC was used to treat low sperm count in men facing fertility issues. The results were enormous. NAC boosted the sperm count and increased fertility. (5) NAC caused a miraculous 32% increase in the levels of healthy normal sperms among the subjects. The subjects also noted a substantial rise in their testosterone levels and overall sexual performance.

Due to such magical antioxidant features, NAC helps protect your sperms and creates a perfect breeding ground for you, increasing your chances to start a family with Semenoll.

Pumpkin Seed Extract

The pumpkin seed extract is an exceptional adaptogen that contains several minerals. Adaptogens are herbs that help improve your physical, mental, and sexual well-being.

Pumpkin seed extract contains a versatile blend of antioxidants, zinc, and magnesium. All these ingredients are crucial for your male sexual health as they help prevent sperms from damage. Also, these nutrients have been shown to improve prostate health and libido. (6)

Tribulus Terrestris

Tribulus Terrestris (TT) is one of the most potent male sex hormone-boosting herbs that play a crucial role in improving your fertility. Semenoll contains an impressive 3,690 mg of Tribulus Terrestris extract – at least two times more than any other supplement. That’s for a good reason for starting your family.

When tested for low sperm count subjects, Tribulus Terrestris enormously increased the sperm count by 78%. Also, all the users noted a remarkable improvement in libido and erection time. In addition, a 2019 study noted that Tribulus Terrestris magically improved testosterone levels. (7) With it comes a significant improvement in all parameters of male fertility and sexual performance.

L-Arginine Hydrochloride

Being the key amino acid in Nitric Oxide (NO) synthesis, L-arginine pumps extra blood into your muscles and genitals. This improved blood circulation leads to the optimal health of your reproductive organs and better sexual performance.

Research at Korea University studied 540 cases of erectile dysfunction. Results showed that L-arginine was extremely effective in improving erectile dysfunction, sexual desire, and intercourse satisfaction. Thanks to the extra blood supply, it can boost your stamina and endurance as you experience bigger, stronger erections that last longer. (8)

Better chances, better performance, better you.

L-Lysine Hydrochloride

L-lysine is an adaptogen herb that helps curb your stress levels. Many studies have linked psychological stress to abnormal semen parameters and reduced paternity. (9) There is a deep link between stress and your sexual health. Stress causes your stress hormone, called cortisol hormone, levels to go sky-high. Cortisol is blamed as an anti-testosterone hormone that causes your testosterone levels to decline significantly. (10) When given to men suffering from stress and anxiety, researchers noticed a drastic reduction in cortisol levels. (11)

Muira Puama

Muira Puama is a Brazilian herb known as ‘potency wood.’ Muira puama is an old herb used to increase the bed, penile hardness, and libido in men for centuries. Several studies found that Muira puama helps improve sexual function in men. For example, in one clinical study, 60% of men experienced an increase in libido, and 50% improved erectile function. (12) Muira puama acts as a nerve stimulant, making you more receptive to sexual stimuli leading to more sexual desire. It also activates receptors in your body for testosterone, which further supports male sexual health.

Dietary supplements do not work to change or alter any of the body’s usual functions. Good quality supplements are intended to provide the body with the necessary nutrients to function better. For example, for problems resulting from calcium deficiency, a calcium supplement provides the required calcium your body is lacking in optimal amounts.

Natural supplements are also least likely to interfere with other drugs. If, however, you are on primary long-term medicines, we recommend you consult with a medical authority before starting a new routine. This rule also applies if you have other hormonal-related issues. Quality dietary supplements work over a specified time, and checking on the manufacturer’s specifications is essential. We further advise that after getting the intended results, you discontinue use.

In addition to the supplements, you can do a few things to aid and make the process faster. Firstly, you have to achieve or maintain a healthy weight and diet. You can also make sure to eradicate any sexual infections from your system. Managing stress levels and being active may also help. Overall, a healthy lifestyle is essential.

There are also a few things you can refrain from, like excessive smoking and alcohol intake. Also, avoid tight-fitting clothes that increase your scrotal temperature. When taking the pills, prevent exposure to toxins like pesticides, smoke, fumes and chemicals. If you are on medications that may hinder fertility, speak to your doctor about it. These all contribute in one way or the other to improve your fertility chances.

Can The Product Increase My Sperm Volume Overnight?

No, and any product that claims so is a scam. Wanting a fast and immediate result is understandable but, in this case, not advisable. It is not something that can instantly occur. Thus, any supplement that advertises such an effect is most likely fake to rob you of your money.

Be careful as it might contain some very questionable ingredients. While there are formulas that may significantly work faster, it still takes at least weeks before you see substantial results. On your part, you can also take some steps to aid the effect.
