Use it or Lose it

Is there any truth to the Use it or Lose it theory?use-it-or-lose-it

Well, this article by David Jaynes makes a very strong case that the theory is actually dead on.

Let’s take a look…

Use it or Lose it-The Cold Hard Facts

Here’s something you already knew: men want to have sex.

Specifically, men who want to avoid erectile dysfunction want to be having sex at least once every week.

A 2008 study in Finland analyzed data of almost 1,000 men between the ages of 55 and 75.

They found men who had sex at least that often were only half as likely to experience ED as those who did not (source).

There’s a lot of reasons for that, which doctors are just now really beginning to investigate. So far, they’ve pinpointed the following:

Erections supply nutrient-rich blood to the penis. 

An erect penis has up to six times the blood flow as a flaccid member, meaning oxygen and other blood-delivered nutrients enter your “bathing suit area” at six times the rate while you’re having sex.

More erections (especially the longer-lasting erections involved in foreplay followed by sex) means more nutrients to the tissues in and around your penis. More nutrients means healthier tissue.

If you’re not having sex at least once a week, the tissues responsible for achieving and maintaining erections may deteriorate from lack of vital nutrients.

Sex enhances testosterone production and uptake.

You probably already know that testosterone is one of the key hormones in erectile health.

You might not know that sex directly improves testosterone production and uptake. A huge range of studies have demonstrated this across multiple situations:

  • As early as 1992, researchers found testosterone levels raised and stayed up throughout the night for both men and women on nights they had sex (source).
  • Multiple studies have found older men who have sex experience age-related ED less frequently than those who have sex less as they age.
  • A study on animals in Britain, and a study on humans in the USA, both showed that anticipating sex raised testosterone levels, but not as much as actually having sex (source).
  • An array of research has shown that lack of sex can reduce testosterone levels. More on this in a moment, because it’s really important.

Frequent sex improves lifestyle factors.

Erectile dysfunction isn’t solely a physical game. Mental and emotional factors play a large role.

Frequent sex can help with many of those factors. It reduces stress, improves body image, gives you moderate exercise (if you’re doing it right), and generally improves feelings of health and well-being.

While it’s at it, sex also improves your relationship with your sex partner. You feel closer to each other, more confident in the relationship, and more forgiving of annoying habits or small mistakes.

Intercourse is protective. 

Remember a little bit ago when I mentioned that lack of sex reduces testosterone levels?

It turns out sex and erectile function can create either an upward spiral or a downward spiral, depending on how often you have sex.

Having sex improves your testosterone levels. Higher testosterone makes you want to have sex more. Having sex more further increases your testosterone, which makes you want even more sex…

Not having sex decreases your testosterone levels. Less testosterone makes you want to have sex less often. Having even less sex decreases your testosterone, which makes you want even less sex…

I don’t have to draw a picture for you to see which of those situations is better for your erectile health.

There’s also a correlation vs. causation thing going on, because men who are generally healthier tend to both have more sex and experience ED less frequently…

But even once you filter out the impact of being healthier, There’s plenty of proven causation between more sex and better erectile health.

Use it or Lose it – More Benefits of Having Sex

But wait! There’s more!

Having more sex helps more than just your erectile health. It carries a heaping helping of other good mojo for your mind, body, and spirit.

For example…

  • Sex increases immunoglobulin A levels, which significantly improves immune function. You get sick less often if you have sex on the regular.
  • Men who have sex at least twice a week are half as likely to develop heart disease as men who have sex once a month or less.
  • Sex releases hormones that reduce pain, and has been found to provide relief for various kinds of chronic pain.
  • Frequent sex reduces your risk of prostate cancer.
  • Sex is moderate exercise, improving cardiovascular health if you do it long enough.

Bottom line, guys: sex is really good for you. You should have some.

Use it or Lose it – Don’t Fly Solo

It seems to make sense that if you can’t have sex once a week, you can get the same benefits from masturbating frequently — but that just isn’t so.

Masturbation actually harms erectile function for a variety of reasons, especially masturbation to video and hard-core pornography. Especially masturbation instead of sex with a partner.

You can read this article for details on the whys and hows of masturbation hurting erectile health.

It’s a bit like the old joke about how a thermos knows whether to keep something hot or cold.

We’re not sure how your body knows the difference between erections and orgasms from masturbation and sex, but it can tell, and the difference can have a serious impact.

Use it or Lose it – Conclusion

Here’s some great news: sex at least once a week is just this side of a medical necessity.

What’s more, it will help improve your relationship with your partner. Having sex releases a basket full of hormones responsible for feelings of love, affection, patience, well-being and attachment.

There’s really no downside to frequent sex, so go find your partner give your mattress a workout.

You’ll be glad you did.


Taurine For Erections

Are you thinking about using taurine for erections?Taurine-for-erections

Good call, when most people think of taurine, they usually think of energy drinks.

After all, taurine is a key ingredient in Red Bull, Monster, and Rockstar, who together make up about 62% of the $50 billion dollar global market.

And while energy drinks might be your beverage of choice, they don’t exactly scream “healthy lifestyle.”

That’s why you’d be surprised to learn that taurine might actually be good for your wood.

Here are three ways that taurine can help improve your erections.

1: Taurine Reduces Penile Fibrosis

Taurine is technically a “sulphur containing amino acid” but in layman’s terms, it’s a protein your body uses, mostly for making stomach bile but also to promote cardiovascular and skeletal health.

It’s positive impact on cardiovascular health is already a sure sign it’s going to be good for your erections (more on that in a minute) but it can help prevent penile fibrosis.

Penile fibrosis (also called Peyronie’s disease) is when scar tissue forms and causes your penis to either bend in a weird way or, in extreme cases, not fill with blood at all (the scar tissue acts like hair clogging your shower drain — blood can’t get through, so your penis doesn’t get hard).

Unfortunately, this seems to be something that just happens naturally with age, although diabetes does increase the risk significantly (source).

But researchers have found that taurine can help. They looked at rats who had diabetes to see whether taurine impacted their diabetic ED (DED) (source).

They found that taurine helped reduce scar tissue to generally improve erectile functionality, concluding:

“It has been demonstrated that taurine supplementation can enhance sexual response and mating ability in aged rats.”

Unfortunately, the researchers haven’t been able to conclude specifically that taurine will definitely help diabetically-induced ED. That said, taurine is a good starting point if you’re perhaps getting older and notice your penis is starting to engorge in odd directions.

2: Taurine Boosts Cardiovascular Performance

You know how we mentioned that taurine can help your cardiovascular health? Well, that doesn’t begin to cover it. Taurine is one of those things that not only directly promotes your heart health, but also does wonders to support all the things around it.

Here’s just a few ways that taurine helps your ticker. (And as a good rule of thumb, if something is good for your heart, it’s good for your penis too.)

Taurine helps you exercise harder and longer

Taurine promotes heart health by helping your muscles. First, it makes both skeletal and cardiac muscles contract harder and faster.

For your heart, it means that more blood gets pushed through your system in less time, increasing oxygen flow and giving you the ability to push yourself further (source).

Second, it helps your muscles work for longer by reducing the buildup of lactic acid.

Lactic acid builds up in your system when the mitochondria in your muscles can’t get enough oxygen to respire aerobically and have to resort to anaerobic respiration, of which lactic acid is a byproduct of.

Taurine reduces its build up, meaning you can continue to exercise for longer.

Taurine reduces your risk of heart disease

First, people with higher levels of taurine have lower  rates of heart disease.  Why?

Because many things that predispose you to heart disease are mitigated by taurine (source).

Taurine correlates to:

  • A lower Body Mass Index
  • Lower blood pressure
  • Lower levels of bad fats in your system
  • Reduced levels and even a reversal of atherosclerosis (arterial hardening)
  • Reduced arterial inflammation
  • Increased NO production and levels in arterial cells (source).

All of these things combine to make your risk of heart disease much lower, your blood flow stronger and your erections harder.

Taurine reduces the risk of obesity

Finally, taurine reduces your risk of obesity. Obesity is a causal factor in heart disease and a major impediment to having a healthy erection.

But taurine can help reduce your risk naturally…

Just 3 grams of taurine every day for 7 weeks is enough to significantly reduce body weight as well as reduce your atherogenic index (a cholesterol measure) (source).

What’s more, obesity can actually cause a decrease in taurine levels, creating a vicious downward spiral. Taurine supplements not only reduce the risk of obesity, but can promote weight loss once people are already struggling.

3: Taurine Boosts Testosterone 

The last major way that taurine can help promote erectile health is by promoting testosterone production.

It’s not exactly a surprise that T levels have a lot to do with your sexual health, and setting aside your steroid users, generally speaking, the more T you’ve got the better off you’ll be.

Which is why taurine is such a powerful supplement.

Studies suggest that taurine can promote T production in a few different ways.

FIrst, taurine reduces oxidative damage to cells, particularly those in your gonads (source).

Second, taurine can increase levels of testicular SOD and gluthatione, the primary antioxidants in your testes, to further reduce oxidative stress (source).

Finally, taurine seems to just increase how much testosterone your body produces. A study on rats found that a 1% increase in taurine can significantly increase FSH, LH, and T levels with no corresponding increase in estradiol (source).

Taurine For Erections – Conclusion:

Taurine, despite its association with energy drinks, is actually an extremely effective supplement for your erections, particularly as you get older.

It helps reduce health problems associated with age-and diabetes-induced ED, it can help improve testosterone production by clearing up free radicals, and it promotes cardiovascular health in a myriad of ways.

For those struggling with erections that just ain’t what they used to be, taurine is a good place to start.

Mint and Testosterone

(Guest Post, written by David Jaynes)

Mint tea might help you warm up in winter or sooth
a sore throat when you’re sick, but it might not be
worth the

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

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).

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

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
