Here are some simple ways to raise testosterone, based on our research.

1. Be lean. Lean men have much higher testosterone than obese men. Eliminating seed oils and other junk food from your diet can help you stay lean. More info on seed oils here.


2. Eat carbs, protein, and saturated fat. Heavily restricting carbs or saturated fat can hurt your testosterone.
3. Improve your thyroid function. The thyroid has major influence over the other hormones, like testosterone. Check if you have autoimmune thyroid disease which is surprisingly common and seems to be caused, for many people, by excessive iodine in the diet. More info on that here.
4. Sleep well! Sleep is when a lot of testosterone is released into your bloodstream.
5. Our research suggests that pesticides are probably responsible for a big drop in testosterone. You can eat low pesticide foods and filter your water to remove pesticides.


6. Many personal care products, such as moisturizer or body wash, contain “xenoestrogens” which are unnatural chemicals which act like estrogen and lower testosterone. There are guides to xenoestrogen-free products on our other site.
7. Microplastics are another type of endocrine disruptor that lowers testosterone. Most of the microplastics that get into your body come from polyester clothes (and other synthetic fabric clothes). Polyester is a type of plastic. Tiny polyester dust particles are rubbing off your clothes. Your body absorbs these microplastics in your polyester underwear. You also breathe in this polyester microplastic dust from your clothes, and it gets into your body. Those microplastics lower testosterone. We have a guide to 100% natural fiber underwear, free of the microplastics that damage your hormones.

If you’d like more help in raising your testosterone, then we can recommend an expert coach for you.

Hans Amato from Testonation.com is my recommendation for raising your testosterone. I’m very picky about recommending someone, because most guides don’t know what they’re talking about, and I’m not ethically comfortable with sending my readers to someone who can’t help. I waited a long time before I settled on Hans. He is one of the only coaches who genuinely understands the reasons for hormone levels changing. You can check out his results and his ideas on his site. His results speak for themselves – over 1200 ng/dl testosterone.

Here’s Hans’s testosterone raising guide:

Does Testosterone vary through the year?

Several studies have asked this, with differing results. But some find that testosterone does appear to vary through the year to a moderate degree. It usually peaks around the Autumn, then drops through the winter to a low in the Spring.

Paris 1975: five healthy medical students and biochemists living in Paris age 26-32. “The peak of plasma testosterone was in November (909 ± 42.7 ng/dl) and the trough was in May (640 ±51.1 ng/dl)”) (source)

1974-1975 in Nijmegen, The Netherlands: 15 healthy men age 24-45. Testosterone averaged 666 ng/dl in April 1974, 744 in July, 762 in October, 665 in January 1975, and 631 in April 1975. (source)

That was the average, but there was a lot of individual variation. Some men peaked in July and some peaked in October. One man looked like this: April: 781 ng/dl, July: 1084, October: 1144, January: 586, April 778. That guy didn’t like January much! However, most of them did not change as much as that. Maybe that guy had very low Vitamin D or something.

Boston, Massachusets in the USA in the 2000’s  – Among 30-79 year old men, testosterone rose until July, reaching 470 ng/dl, and then began dropping to a low in December of 385 ng/dl (source) The study didn’t find the differences to be significant however.

How much onion to increase testosterone? Perhaps none

If you look around on the internet, you’ll hear claims that onions increase testosterone, and all kinds of other statements like that.

Just how much onion does it take to increase testosterone? Well, the one study done on humans showed no major testosterone increase, but we can tell you how much the rats in the other studies ate.

To match what the rats ate, a person would need about 2 onions per day.

Doing the math

Here’s why. Most studies were done on rats. Studies usually used onion juice between 0.5 ml and 6 ml daily, per rat. (source) If that was a 670g male wistar rat, then equivalent amount of onion juice for a 180 lb man would be 61 ml to 731 ml of onion juice daily. 61 ml is something like as much as there is in 2/3 of an onion, and 731 ml is about as much as there is in a little under 8 onions. (These are all very rough estimates) To match the amount that most of the studies used, you’d probably eat about 2 onions worth of juice daily.

Don’t eat tons of onions though

But the real answer is that stuff like this really isn’t the ideal way to improve your health and hormones. As I mentioned, the study that fed humans onion extract found no major effect on testosterone. Being lean, sleeping enough, and eating a nutrient dense and natural diet are probably way more effective for increasing testosterone.

I also can’t say what eating 2 onions every day might do to your body, it might be hard on your digestion, and I know I would get sick of it quickly.

So how can we raise testosterone then?

However, it’s understandable that people are looking for testosterone boosting advice other than “get healthy,” since even healthy and fit people today seem to have lower testosterone than people in the past did. Our site has extensive discussion of the fall of testosterone levels over the years.

Why is testosterone low today, even in healthy and fit people? It probably isn’t because we eat less onions… We aren’t sure what exactly is making testosterone levels fall, but we have identified a few things.

Pesticides

Countries with lots of pesticide usage have lower testosterone on average.

More discussion of that in our article.

Endocrine disruptors and hunter gatherers

Endocrine disruptors are chemicals that mess up your hormones. People in the past (when testosterone was higher) were not exposed to these chemicals.

Hunter gatherers are mostly not exposed to endocrine disruptors and we’ve collected data here showing that their testosterone is frequently much higher than ours, sometimes more than double on average. (Our article about that)

Common sources of endocrine disruptors are skin products like shampoo, moisturizer, and sunscreen. Another source is microplastic dust from polyester clothes, carpets, and furniture.

Safer, more natural shampoo is available here: Baby Shampoo & Body Wash by Dapple Baby.

Polyester fabric can be replaced with natural fabric like 100% cotton or 100% wool. You can put a 100% cotton sheet over top of polyester fabric furniture to prevent the polyester from putting microplastic dust into the air in your house.

Clothes, and especially underwear, ought to be cotton or wool. Beware of blends that claim to be cotton or wool but are actually partly polyester or another synthetic fabric. It’s kind of hard to find truly 100% cotton or 100% wool underwear, so we saved you the trouble:

100% merino wool boxers:

And some 100% cotton boxers:

What’s the bottom line?

In conclusion, eating natural food (ideally organic), minimizing the use of skin products that have anything weird in them, and minimizing microplastic dust from synthetic fabrics are all valuable things you can do to keep your hormones healthy (once you have made sure you are sleeping well and getting healthy and lean in general). Clever tricks like eating onions really aren’t something you have to focus on.

Good luck!

Testosterone levels in Bangladesh

In Dhaka, Bangladesh in 2015, testosterone was 423 ng/dl.

Is Bangladesh’s average testosterone level lower than the testosterone levels in other places in the world?

Much of the world is having an unusual, unexplained fall in testosterone since about 1980, at least. Bangladesh is unfortunately not spared from this problem. The low levels of testosterone here are pretty similar to those found after the rest of the world’s decrease. Unfortunately we don’t have historical data from Bangladesh to see what testosterone levels used to be here, but the levels would likely have been a lot higher and healthier, since we have data showing other countries in South Asia with higher testosterone in the past than what they have today.

Testosterone levels in Belgium

In the land of Belgium around 2008, the average man’s testosterone was 561 ng/dl.

Is testosterone in Belgium lower than the testosterone levels in other places in the world?

Testosterone is decreasing in many places around the world. (We think that the blame can be placed on chemicals called endocrine disruptors and seed oil in the diet) Belgium has had some decrease in testosterone like many other places. However, they’ve still maintained pretty good testosterone levels, and their current level isn’t as bad as most other places. So that’s good! If you’d like to know more, please see the article on this site about how testosterone has fallen.

What’s the average testosterone level in the other countries?

Testosterone is decreasing in many places around the world. (In our opinion it’s chemicals called endocrine disruptors and seed oil in the diet) Unfortunately, this is happening in Brazil too, which is having a decrease in testosterone like most other countries, and is now quite low. We think it might be Brazil’s heavy use of pesticides that’s doing it. If you’d like to know more, you can check out our article on how and why testosterone has fallen over the years.

Note that the trend line doesn’t really mean much here, without a lot more data.

Is the testosterone level in Cameroon lower than the rest of the world?

Not at all! Testosterone is falling in many countries in the world. But Cameroon seems to be “immune” to this drop in testosterone. You can see our research on testosterone levels around the world, if you’d like to learn more.
