Overview

There is a common myth that infertility only affects older men. The truth is that you can start experiencing diminished semen volume as early as your 20’s. So if you want to maintain your reproductive health, this is something that you should keep in mind. So what can you do to improve your fertility as a man?

The makers of Semex think they have a solution. Semex is a daily dietary supplement that makes some very unique and questionable claims. Firstly, it is a supplement that is supposed to increase semen volume with every ejaculation. There they state that Semex will increase male vitality.

But one of the more outrageous claims is that Semex will improve the taste of the user’s semen. So is there any truth to these claims? Will Semex work for you and if so, what kind of effects can you expect? Find out in the following Semex review.

What Is Semex?

Semex is an over-the-counter supplement that can be classified as a male enhancement supplement. It comes in capsule form and there are 90 capsules per container. However, at a suggested serving size of three capsules a day, this supply will only last about thirty days.

In any case, the manufacturers of Semex claim that it is safe because it is made with high-grade ingredients. They also claim that Semex is unique among male enhancement supplements because it is one of the few that is supposed to improve the taste of the user’s semen.

Some men have reported liking the effects of Semex. They say that it really did increase semen volume and ejaculatory intensity. Some have even claimed that Semex gave them more energy. For the most part though, men take Semex primarily to improve their fertility.

Who Is the Manufacturer Of Semex?

The maker of Semex is a company called Newt Nutrition LLC. Newt Nutrition is based in Safety Harbor, Florida and they claim to make their products in a Good Manufacturing Practices-approved facility.

The company also states that they 3rd party lab-test all of their products to make sure they are safe and free of contaminants. They sell their supplements exclusively through online retailers.

How Does Semex Work?

Semex is not claimed to work the way most male enhancement supplements are. In fact, the company that manufactures it makes the wild claim that Semex will help improve the taste of the user’s semen. Unfortunately, there is nothing in the formula that backs this assertion up.

However, other claims that Semex will support male fertility and vitality may have some scientific backing. For instance, one of the active ingredients in the Semex formula is ginseng. In preliminary clinical studies, ginseng has been found to promote spermatogenesis.

This appears to validate the claims that Semex will help increase semen volume as spermatogenesis is a process by which semen is produced. Ginseng may also help modulate sexual hormones which could lend credibility to the claim that Semex will improve male vitality.

Semex Key Ingredients – Are They Safe And Effective?

The following section will provide a breakdown of the Semex active ingredients:

Zinc

Zinc is a mineral that is involved in many bodily functions. Some studies have even found that zinc has antioxidant effects that are linked with sperm quality. These studies suggest that zinc supplementation could help to improve sperm motility and morphology as we read in the following study excerpt:

Zinc as a biological marker and an antioxidant affects sperm count, motility and morphology.

Tongkat Ali

Tongkat ali is an herb that is often used in male enhancement supplements for its apparent effects on male sexual hormones. Studies have found reason to believe that tongkat ali improves semen quality and increases conception rates. More studies are needed to confirm these results though.

Muira Puama Root

Muira puama is a natural ingredient that has also been closely linked to sexual and reproductive benefits. Some studies have suggested that muira puama extract could help improve sperm quality and prevent gonadotoxicity as we read in the following study excerpt:

This research demonstrated the protective effects of Muira puama extract against cyclophosphamide induced gonadotoxicity in rats. However, additional research is necessary to examine its molecular mechanisms and possible clinical applications.

Maca Powder

Maca is a root vegetable that originates in the Andes mountains. Clinical studies have revealed that maca has the potential to reduce physical fatigue and enhance male fertility by increasing sperm volume. However, it remains to be seen if maca maintains its potency in powder form.

Panax Ginseng

Panax ginseng has shown promise for promoting male fertility in preliminary clinical trials. However, it has not been tested in advanced, long-term, high-quality trials. A Food Supplement and Biomaterials for Health report states that there is optimism for panax to be used to treat infertility; but they also state that:

in order to establish absolute conviction, it is imperative to conduct well-designed placebo-controlled double-blind clinical trials.

How To Use Semex?

The printed instructions on the label for Semex say that users should take 3capsules a day in the morning with or without food. It is also advised to ask your physician about how to take Semex.

Benefits Of Semex

  • Increased Semen Volume – Increased semen volume may be desirable for men who are trying to conceive a child as more semen increases conception rates. This is not an effect desired by all men though.
  • Improved Taste of Semen – The makers of Semex say that this supplement will improve the taste of the user’s semen but there is nothing in the formula that suggests it is capable of such an effect.
  • More Vitality – We are also told that Semex will improve male vitality. This claim may be justified by the presence of maca powder in the formula as maca may help stave off physical fatigue.

Side Effects Of Semex

There have not been many complaints about side effects but some men have stated that Semex caused gastrointestinal distress so just keep that in mind. If you are allergic to any of the active ingredients in the Semex formula, please note that your chances of side effects will increase. It’s always a good idea to talk to a physician about potential side effects.

Safety Of Semex

We are told that Semex is made in a Good Manufacturing Practices facility and that it is 3rd party lab-tested for safety. The ingredients are also all-natural. However, you should always ask your trusted healthcare practitioner about any new supplement you are thinking of taking. You should also make sure you are not allergic to any of the ingredients.

Semex Price

The price for a single container of Semex (containing 90 capsules) runs for about $48 on major 3rd party retail sites like Amazon. This price may vary depending on where you buy Semex though.

What Do the Semex Reviews Say?

Some reviews say Semex increases energy while others complain of side effects:

I took the suggested four pills per day for 20 days straight before writing this review. I honestly could not tell the difference in volume or the taste. The pills are easy to take but I would have preferred less number of pills per day even if it meant bigger pills. The packaging is good. I feel like after taking SEMEX, the smell of my urine became more pungent. – Hyung

I was interested in trying these but, unfortunately, I didn’t get much of a chance. I like that these are made in the USA and that contributed to my picking this brand. The capsules are medium sized and hold a white powder. You do have to take 4 of them for a serving. I tried them and on the second day I noticed some GI issues. – Ethan

Have good volume but day 2 already doubled as wife couldn’t believe it.

Semex Review – Final Verdict

Semex is a unique male enhancement supplement that focuses on male fertility. But is it a good male enhancer? It may improve male vitality and give you more energy. It may also increase semen volume.

On the other hand, some users have questioned the overall benefits of this supplement and have complained of gastrointestinal issues.

If you are trying to conceive a child, Semex may help. If you aren’t, there are other male enhancement supplements that would be more beneficial to you.

With countless male performance enhancement supplements available on the market today it seems impossible to find "the right one." Sexual performance declines naturally as men age, which may contribute to feelings of inadequacy or embarrassment. Male performance enhancement supplements should be based on four key factors: active ingredients, ability to support sexual stamina, enhance arousal, improved* sexual desire and backed by clinical studies.

Below you'll find some of the most effective male performance enhancement supplements on the market today, in our opinion.
