Mint and testosterone have a bit of a chequered past, with studies indicating that consuming mint reduces men’s testosterone levels.

This article is going to give you the rundown on what the research says about mint and testosterone, and why it might be worth avoiding for your T levels, your balls, your fertility, and your sex life.

Mint, Spearmint, Peppermint & Testosterone

First, lets clarify what we’re talking about. Peppermint, spearmint, apple mint, ginger mint, chocolate mint — all are part of the mentha family.

For the sake of concision, we’re going to just call all of these types of mint mint, because they all cause the following problems to one degree or another.

It’s also worth noting that mint and its mentha family buddies aren’t just found in herbal tea. Toothpaste, gum, deodorants, air purifiers, cooking, cocktails — mint is found in lots of places.

So if you’re looking to reduce your mint intake, remember to look closely at the products that you interact with every day.

Now that’s out of the way, let’s look at what the science says about this.

Mint and Testosterone – What The Science Says

One of the first studies that looked at this issue was published back in 2004 in Urology by three researchers from the Suleyman Demirel University Medical School in Turkey.

They looked at the effects of peppermint tea on rats, measuring testosterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH) levels.

The researchers took 48 rats and divided them into four groups, one control getting water and the other three receiving progressively higher doses of mint (either spearmint or peppermint).

What they found was that the control groups produced significantly more FSH and LH while levels of testosterone plummeted. In the lowest-dose group of peppermint, levels fell 23%. Spearmint dropped testosterone levels by 51%, and that wasn’t even at the highest dose.

The researchers concluded that, despite the benefits of mint tea, we should be aware of the “toxic effects” that it can have on testosterone (source).

And this isn’t the only study…

Three years later, the same researchers published a second study in Phytotherapy Research and reached a similar conclusion. This time, they looked at levels of testosterone in women suffering from hirsutism.

They looked at 21 women, 12 with polycystic ovary syndrome and 9 with idiopathic hirsutism. They had them drink spearmint tea twice a day for 5 days at a specific point in their menstrual cycles.

What they found confirmed earlier studies. Their free testosterone levels dropped and their FSH and LH levels rose significantly.

They also found increases in Estradiol, the primary female sex hormone. And while they concluded that more studies needs to be done, it’s still pretty damning evidence that mint makes T levels go down (source).

It’s worth noting here that men’s and women’s hormones, while they do different things and are present in different amounts, are actually the same stuff. Despite their names, men produce LH, FSH, and oestrogen — they just do it in smaller volumes than women.

Conversely, women do produce testosterone, they just produce less of it.

Mint and Testicular Atrophy

Now as you might know, testosterone and your balls are pretty closely related…

And in general, the lower your testosterone, the more testicular atrophy you’ll experience. Therefore, the more mint you consume, the worse off your balls are going to be.

In fact, in 2008, a group of Indian researchers confirmed this in a study published in Food and Chemical Toxicology.

They looked at rats and the “probable correlation between oxidative stress in hypothalamic region and antiandrogenic action of [spearmint] on rats”.

In other words, does giving rats spearmint correlate to increased oxidative stress in the hypothalamus and decreased testosterone levels? And if so, why?

By looking at enzyme activity levels, the researchers were able to track oxidative stress levels. As the spearmint doses went up, enzyme activity went down and thus, the oxidative stress must have increased.

Second, their analysis found that:

  • Testicular enzyme activity decreased
  • Testosterone protein activity decreased

The researchers concluded that spearmint does cause a decrease in testosterone by causing oxidative stress in the hypothalamus which in turn causes LH and FSH production to decrease.

Then, as the body becomes aware that the hormones are out of whack, it decreases testosterone production by reducing the supply of enzymes and proteins needed to build testosterone molecules, resulting in an overall net decrease of free T in your system (source).

It’s like your body is building a skyscraper, but someone at the head office needs to stop the project…

Instead of going to to the worksite and closing things down, they just call the concrete plant and the steel plant and tell them to stop making deliveries. Without new building materials, production grinds to a halt.

Conclusion? Mint can be a real ball buster.

Mint and Fertility

Of course, you can’t decrease your testosterone levels and cause your balls to shrivel up and induce oxidative stress on your brain and not expect at least some impact on fertility.

Which is exactly why in 2014, researchers from Iran collaborated to publish a study in the Avicenna journal of phytomedicine about male fertility in rats and mint (they used spearmint).

They got male rates and split them into four groups. One group received no spearmint (control) and the rest received either 10, 20, or 40 mg/kg every day for 45 days.

This allowed the research to make dose-dependent conclusions.

After the 45 days, they looked at sperm health based on a variety of factors, including:

  • Sperm count
  • Sperm motility (progressive and immotility rates)
  • Serum testosterone concentration

What they found was that spearmint did have a negative impact on virtually every fertility metric. Sperm count decreased. Fast motility decreased. Immotility increased. Serum testosterone decreased.

Now to be fair, researchers didn’t find these changes in statistically significant amounts. Plus, there was no difference in the number of offspring between the control and experimental groups of rats; however, their doses were relatively low (source).

With that in mind, small doses of mint probably won’t affect your sperm too terribly. But at higher doses you could run into serious problems.

And remember: this is on top of testicular atrophy and low T levels, both of which WILL cause infertility.

So while the mint might not have  direct effect, it’s definitely not helping things along. If you’re looking to pro-create, I’d say it’s best to keep off the mint, especially in high doses.

Mint and Erectile Dysfunction

Now, onto the matter at hand. With all of this information that science has supplied, how much softer or less frequent is your wood going to be?

Unfortunately, there hasn’t been any concrete research on mint and ED. There’s no smoking gun.

But think about this:

  1. Low testosterone contributes in a big ways to erectile dysfunction.
  2. Oxidative stress contributes to erectile dysfunction.
  3. Sperm health is a bit of a ‘canary in the coalmine’ for testicular health and your wood.
  4. Testicular atrophy and ED often go together.

So with all this in mind, do you think that mint is HELPING your sex life?

I think we can confidently say: ‘probably not’.

Mint and Testosterone – Conclusion

What does all this mean?

Does it meant that we can safely chew gum and drink mojitos without any consequences?

Does it mean we should put mint up there with plutonium on our list of ‘don’t touch it with a ten foot pole’?

Does it mean we should wait for science to tell us that mint is definitely good or definitely bad?

It’s up to you.

To be clear, there is currently no scientific evidence, correlative or otherwise, linking mint to erectile dysfunction.

However, there is LOTS of evidence that links a number of causal factors for ED and low testosterone to increasing mint intake.

Basically, mint creates an environment that makes it difficult to get hard, easy to stay soft, and difficult to maintain healthy testosterone production.

My recommendation?

Don’t develop a mint tea habit. Don’t chew gum all the time and don’t race through altoids.

But don’t become a mint-nazi.

The odd cup of tea when you’re under the weather or the odd sprig of mint in a summer salad isn’t going to kill you and isn’t going to induce ED.

There are other more important factors when it comes to your testosterone levels and your ED that will have a much bigger impact.

So live a little!

After all, who doesn’t love a mojito on a hot beach?

 

Oysters and Erections

(Oysters and Erections, written by David Jaynes)oysters and erections

Okay. This one isn’t exactly news.

Folks have been eating oysters as an aphrodisiac for a really long time.

This all started back in the days of the “Doctrine of Signatures,”…

An idea from back in the day when people assumed every plant and animal was custom made by a higher being.

The idea was that the higher being designed plants and animals in shapes that gave us a hint about how they might be useful to us.

A plant with a flower like an eye would help with vision. Birds, because they flew, might help with breathing problems.

And anything shaped like a dong or a vagina would help with fertility, libido, erections, and anything else related to sex and marital bliss.

Oysters on the half shell look a bit like a vagina, but both clams and oysters in the wild underwater look a lot like one.

And so early naturalists assumed that meant they’d make people horny.

Fast-forward to now, and it turns out they were — through no fault of their own — right. Oysters do a lot of stuff to help put and keep lead in the old pencil.

Let’s take a look at exactly how.Continue reading

Cordyceps. This is not a joke…

Traditional healers have used it to treat everything from energy and stamina, to libido, to appetite, to sleep problems.

Don’t let its nickname “killer fungus” fool you. It only slowly kills and turns into zombies when in an insect host.

Recent research has sought to find out how much of the traditional advice is up to modern standards. Like so many traditional remedies, the results are positive….

Cordyceps can help with testostosterone in two (and a half) different ways.Continue reading

Does Masturbation Lower Testosterone in Men?

No, masturbation won’t make you go blind.

No, it won’t grow hair on your palms.Does-masturbation-lower-testosterone-in-men

No, it’s not a moral offense that will require three Hail Marys.

It’s neither a sin, nor a public health menace, no matter what the religious sorts in your life and or some YouTuber might try to tell you.

Masturbation is a natural and healthy part of any adult’s life, and mutual masturbation can be a fun part of a healthy sexual relationship.

But excessive masturbation, especially to hardcore pornography, can cause some serious problems. Continue reading

In a round about way, it sure does, which explains why its one my all time favorite sex boosting supplements.

And unlike most other herbs, we have plenty of science that demonstrates how effective this plant actually is.

Studies that prove that tongkat ali increases Bio-Available testosterone by lowering estrogen AND cortisol, two hormones that have a negative impact on production of the hormone.

Tongkat is also a strong libido enhancer, and according to one study, it significantly increased erectile function in male rats.

Tongat ali also improves sperm quality, with one human study showing that it boosted sperm motility by a whopping 44%, and semen volume more than 18% (source).

All this to say…Continue reading

Does Boron Increase Testosterone?

Does Boron Increase Testosterone?Does boron increase testosterone levels in men?

Good question…

Once upon a time, our ancestors got plenty of boron in their diets.

We got it by eating plenty of  berries, nuts and fruits. This was a good thing, since boron is important for bone density, joint health, and brain function.

It’s also been used as a performance enhancer for athletes.

Doses of boron on the days of competition or heavy training were known to generate measurable gains in speed, strength, and even aggression.

It was one of those things jocks take instead of steroids or HGH to get some of the benefits of those banned substances.

But then we, as a species, started eating progressively crappier foods. Now, boron is in short supply in the normal human diet. We’re still getting enough for basic essential health, but in some men the shortfall impacts testosterone levels.

If you’re one of those men, supplementing your boron intake could boost your testosterone and help repair several aspects of your general and sexual health.

How does boron increase testosterone? Funny you should ask…Continue reading

Does Drinking Alcohol in Moderation Lower Testosterone Levels

Does drinking alcohol in moderation lower testosterone levels?

If you have an internet connection, you’ve almost certainly read that booze can impact your testosterone production.

And that’s accurate: alcohol intake decreases testosterone. Period.

But that truth isn’t the whole story.

It turns out that, if you pay attention, don’t go crazy, and do a few things to make up for the decrease, you can enjoy the occasional drink without wrecking your testosterone levels.

Here’s how that works:Continue reading

Natural Aromatase Inhibitors for Men

(Natural Aromatase Inhibitors for Men, written by David Jaynes)Natural Aromatase Inhibitors for Men

Aromatization has nothing to do with how much or badly you smell.

But it can potentially be even more destructive to your sex life than smelling terrible.

It can also impact your health in a wide range of other areas.

But let’s start at the beginning.

Aromatization is a chemistry term that refers to a variety of conversions from one thing to another thing.

In the human body, that conversion is from testosterone to estradiol – the main form of estrogen in males.

This process is a necessary part of the systems which keep your body’s hormones in balance. But if things are out of balance it can lead to excess estrogen, especially as you age.

As a male, you do not want excess estrogen.

Just a few of the lovely gifts this condition can give you include:Continue reading

Do Probiotics Increase Testicle Size?

You’ve heard of probiotics by now, probably in the context of fixing your “gut flora.”

That’s the bacteria culture living in your stomach that helps you break down and process food.

Yogurts like Activia advertise their value for digestive health.

But some probiotics can also help with the size of your testicles.

Studies suggest the right kind of bacteria in your system can stimulate your body to improve your testicular function, testicular size, and sexual health.

This research is newer and ongoing (though some of it we’ve known from folk medicine for a very long time), so let’s take a look at what we know as of today. Continue reading

Weak Erection and Testosterone

(Written By David Jaynes)

Testosterone is known as the “man” hormone. Weak-Erection-and-Testosterone

It’s what puts hair on your chest, muscles on your frame, and passion in your sex life.

But with age, environmental factors, lifestyle changes or simple bad genetic luck, testosterone can decrease – sometimes to the point of health problems.

We’re obviously talking about weak erection / testosterone problems, but we’re also talking about how-long-you-live health problems.

Stuff like heart disease and obesity.

If you have weak erections, this can happen because of a variety of factors. Some of them are caused by isolated issues like high blood pressure, stress or other health conditions.

In other words…

The link between a weak erection and low testosterone exists, but the cause of the problem is not always direct, as Low-t leads to other health conditions….

Conditions that can eventually lead to blatant erectile dysfunction if you don’t get a grip on them.

For example…Continue reading
