|Testosterone levels in Norway||Testosterone levels in Finland|
Testosterone varies a lot around the world. We found hundreds of studies from all around the world. According to the studies, men who live in countries like Uzbekistan and Nigeria have high testosterone, while the men who live in countries like China and the USA unfortunately have unhealthy low testosterone. (But a few decades ago they had pretty high testosterone too!)
The Highest Testosterone in the World
Testosterone has been falling since the early 1980’s at least. For this reason, we are only looking at data from 2000 or later here. Around 2012, the region with the highest testosterone we’ve seen is Chita, Russia, where the men at an average age of 34 have testosterone levels of 1022 ng/dl! (source) Now, testosterone declines with age, and studies are done on all different age groups. To make the studies comparable, we’ve come up with a way to calculate what a normal male population of all ages would have as their average testosterone, and we’ve done this to all the studies to make them comparable. So Chita, Russia gets corrected to 905 ng/dl to reflect a population that includes all ages. 905 for the whole population is the number that we’ve found to be the highest on our list.
Chita is in southeast Siberia, a little above Mongolia.
The next highest number is from Peshawar, Pakistan. This is the part of Pakistan where the Pashtun people live, close to Afghanistan. At age 18-25 around 2016, men in Peshawar had testosterone of 1090 ng/dl. (source) That age corrects to 893 ng/dl.
Next is Ahwaz, Iran in 2016. Here, men with an average age of 20, have 1100 ng/dl testosterone. Age corrected, that’s 887 ng/dl. (source)
In Chiang Mai, Thailand, the Hmong people have 975 ng/dl testosterone at an average age of 37. That corrects to 884 ng/dl.
In Ibadan, Nigeria, men with an average age of nearly 38 have 940 ng/dl testosterone, which age corrects to 858 ng/dl. (source)
These are the top 5 highest testosterone places I’ve seen. Some of these countries have very different testosterone levels in different parts of them, however.
The Highest Testosterone Countries
While Siberia has very high testosterone for the most part, most Russians live thousands of miles to the west. So we can’t really say that the testosterone in Chita reflects the average testosterone in Russia as a whole.
For the following info, we’ve tried to pick areas that are as representative as possible of where much of the population of a country lives, or we’ve averaged studies together to represent a large piece of a country.
Here are the Top 5 testosterone levels in countries from which we could find acceptable data, adjusted for age by us when possible, and no earlier than 2010:
- Democratic Republic of the Congo – 852 ng/dl testosterone (South Kivu province) (Note: This result is questionable, since I am interpreting what I believe to be a typo in the original study.)
- Uzbekistan – 773 ng/dl testosterone (Tashkent)
- Ghana – 739 ng/dl testosterone (Accra)
- Cameroon – 701 ng/dl testosterone (Djutitsa)
- Azerbaijan – 694 ng/dl testosterone (Baku)
To see testosterone levels in the rest of the world, keep scrolling. But first, we want to ask what is going on with how widespread low testosterone is?!
Why is testosterone so low in some places?
Sadly, testosterone appears to be low to the point of being unhealthy in much of the world. The studies suggest that testosterone used to be pretty high all over the world before the 80’s. Testosterone has fallen in these places, while staying high in the other places. More info here: Testosterone Levels 100 Years Ago
We have found that low testosterone correlates with PUFA consumption in the diet (seed oils are a big source of this), and low testosterone also correlates with agricultural chemical use by country.
Seed oils might lower testosterone
Avoid seed oils and PUFA by eating a diet where the fat comes from butter, coconut oil, and beef tallow, rather than from canola oil, soybean oil, fast food, and manufactured food. More info here: PUFA Might Lower Testosterone
Low testosterone might be from agricultural chemicals getting into your body
Agricultural chemicals get into the food and water. More info here: Pesticides May Lower Testosterone
You can lower the amount of chemicals you ingest by eating organic food, or food raised by a farmer that you know doesn’t use chemicals. A big source of these chemicals in your body is the water you drink. Agricultural chemicals run off fields and end up in your water supply. A good water filter can remove testosterone-lowering chemicals and make a big difference for you.
Testosterone levels in the rest of the world
Here are the testosterone levels in the rest of the countries, no earlier than 2010, and age-adjusted:
|French West Indies||563|
|China (Eastern, where most live)||480|
Important note: There are many countries I have no data from, or no usable data from. Very possibly these countries might have higher testosterone than countries on this list.
