Is Where You Live Affecting Your Testosterone? Global Rankings Reveal a Surprising Pattern
Discover the 2026 testosterone levels by country ranking. Nigeria ranks 8th at 625 ng/dL, while Uzbekistan leads at 773 ng/dL. See the full list and what the data really means.
Could your geographic location be one of the hidden factors influencing testosterone levels?
When people discuss testosterone and hormonal health, the conversation usually focuses on familiar factors such as sleep, exercise, body weight, stress, diet and overall lifestyle. But an international dataset published by World Population Review has drawn attention to another possible factor: where people live.
The 2026 World Population Review compilation lists estimated average testosterone levels for 87 countries, measured in nanograms per deciliter (ng/dL). According to the ranking, Uzbekistan records the highest figure at 773 ng/dL, followed by Croatia at 752 ng/dL and Cameroon at 731 ng/dL.
Nigeria also appears prominently, ranking 8th globally with a reported 625 ng/dL.
However, there is an important scientific caution. These figures should not be interpreted as proof that living in a particular country automatically causes higher testosterone. World Population Review says its figures were compiled from studies conducted across different years and acknowledges substantial limitations in comparing the data directly.
Nigeria Ranks 8th With 625 ng/dL
For Nigerian readers, one of the most interesting findings is Nigeria's position near the top of the list.
According to the World Population Review compilation:
Nigeria — 625 ng/dL — Rank 8
Nigeria is listed behind Uzbekistan, Croatia, Cameroon, Azerbaijan, Mongolia, Ethiopia and the Democratic Republic of the Congo.
Other African countries appearing in the upper portion of the ranking include:
- Cameroon — 731 ng/dL
- Ethiopia — 671 ng/dL
- DR Congo — 668 ng/dL
- Sudan — 588 ng/dL
- Uganda — 586 ng/dL
- Ghana — 569 ng/dL
- Algeria — 563 ng/dL
- Kenya — 552 ng/dL
The figures make for an interesting international comparison, but they should not be treated as a biological scoreboard for entire populations.
Which Country Has the Highest Testosterone Level?
The current World Population Review ranking places Uzbekistan first at 773 ng/dL.
The top 10 are:
Rank| Country| Reported Testosterone
1| 🇺🇿 Uzbekistan| 773 ng/dL
2| ðŸ‡ðŸ‡· Croatia| 752 ng/dL
3| 🇨🇲 Cameroon| 731 ng/dL
4| 🇦🇿 Azerbaijan| 694 ng/dL
5| 🇲🇳 Mongolia| 693 ng/dL
6| 🇪🇹 Ethiopia| 671 ng/dL
7| 🇨🇩 DR Congo| 668 ng/dL
8| 🇳🇬 Nigeria| 625 ng/dL
9| 🇸🇦 Saudi Arabia| 599 ng/dL
10| 🇸🇩 Sudan| 588 ng/dL
World Population Review notes that testosterone is measured in ng/dL and that most of the underlying data were compiled from studies dated between 2010 and 2022, with some countries represented by older research. Croatia's figure, for example, comes from 1987, while Armenia's figure comes from 1980.
That difference in study dates is one reason the ranking needs to be interpreted carefully.
What About the United States and Other Western Countries?
The United States appears at No. 49 with 459 ng/dL in the World Population Review dataset.
Several other major Western countries appear below the midpoint of the list:
- 🇬🇧 United Kingdom — 521 ng/dL
- 🇮🇹 Italy — 480 ng/dL
- 🇵🇹 Portugal — 472 ng/dL
- 🇨🇠Switzerland — 472 ng/dL
- 🇺🇸 United States — 459 ng/dL
- 🇳🇴 Norway — 443 ng/dL
- 🇩🇪 Germany — 434 ng/dL
- 🇫🇷 France — 420 ng/dL
- 🇦🇺 Australia — 403 ng/dL
- 🇨🇦 Canada — 402 ng/dL
- 🇮🇪 Ireland — 394 ng/dL
- 🇫🇮 Finland — 375 ng/dL
At the bottom of the published ranking, Czechia is listed at 315 ng/dL, followed by Latvia at 342 ng/dL and Bahrain at 346 ng/dL.
The difference between the highest listed figure, 773 ng/dL, and the lowest, 315 ng/dL, is 458 ng/dL.
That is a striking difference on paper.
But does it mean people in Uzbekistan naturally have more than twice the testosterone of people in Czechia?
Not necessarily.
Geography May Matter — But It Is Not the Whole Story
The biggest mistake would be to look at these numbers and conclude that geography directly determines testosterone.
Hormone levels are influenced by a complex combination of biological, environmental and lifestyle factors. Age, body composition, physical activity, sleep, nutrition, illness, medications, stress and the timing and method of testing can all affect testosterone measurements.
Even within the same country, testosterone levels can vary considerably from one individual to another.
This means that a person living in a country with a high national average can still have relatively low testosterone, while someone living in a country lower on the ranking can have a perfectly healthy testosterone level.
In other words, your passport is not a hormone test.
Why Are International Testosterone Comparisons Difficult?
There is another major issue hiding behind the rankings: the studies aren't necessarily measuring identical populations under identical conditions.
World Population Review itself acknowledges that the dataset combines research from a wide range of sources, years and methodologies. It also warns that some sources have less rigorous statistical practices and says the compilation should not be considered scientifically sound.
For example, if researchers test one country's participants in one decade and another country's participants decades earlier, comparing the two averages as though they were collected under exactly the same conditions can be misleading.
Other questions also matter:
- What age groups were tested?
- Were participants healthy?
- Were testosterone levels measured in the morning?
- Were researchers measuring total or free testosterone?
- How large was the sample?
- Were participants physically active?
- Was body weight taken into account?
- What laboratory methods were used?
- Were the participants representative of the country's wider population?
Without standardized answers to these questions, a global ranking can be interesting without being definitive.
Lifestyle Still Matters
Although geographic patterns are fascinating, there is much stronger reason to focus on everyday factors that influence hormonal health.
Sleep is important because inadequate or disrupted sleep can affect hormone regulation.
Physical activity also matters. Resistance training and maintaining a healthy level of physical fitness are commonly associated with healthy metabolic and hormonal function.
Body composition is another consideration. Excess body fat is associated with lower testosterone in men, and improving overall metabolic health can be beneficial.
Nutrition matters as well. A balanced diet providing sufficient calories, protein, healthy fats, vitamins and minerals supports normal physiological function.
Stress should not be ignored. Chronic psychological and physical stress can affect several hormonal systems.
These factors can be far more useful for an individual than simply looking at the average figure assigned to their country.
Does a Higher Testosterone Number Always Mean Better Health?
Not necessarily.
Testosterone is an important hormone, particularly for male reproductive and metabolic health, but more is not automatically better.
Testosterone levels need to be interpreted alongside symptoms, age, medical history and appropriate laboratory testing.
A single testosterone measurement also does not necessarily tell the whole story. Hormone concentrations can fluctuate, and testing conditions can influence the result.
For anyone concerned about low testosterone or symptoms associated with hormonal changes, the appropriate approach is to speak with a qualified healthcare professional rather than attempting to diagnose a hormone problem from an online country ranking.

So, Is Geography the Hidden Factor?
The answer is possibly part of the story, but there is not enough evidence to call geography the ultimate factor.
The differences between countries are certainly interesting and may encourage researchers to investigate environmental, genetic, nutritional, occupational and lifestyle differences.
But the available ranking does not establish a cause-and-effect relationship between location and testosterone.
Instead, it provides a snapshot of measurements collected from different studies, populations and periods.
For individuals, the more important question is not whether their country ranks first or 87th. It is whether their own hormone levels are appropriate for their age, health status and symptoms.
The global testosterone ranking has produced an intriguing conversation about how environment and lifestyle may interact with human biology.
Uzbekistan tops the current World Population Review compilation at 773 ng/dL, while Nigeria ranks an impressive eighth at 625 ng/dL. Meanwhile, the United States is listed at 459 ng/dL.
But these figures should be viewed as interesting population-level estimates rather than definitive measurements of national testosterone levels.
Where you live may be one piece of a much larger puzzle—but sleep, physical activity, nutrition, body composition, stress, age and individual biology remain crucial parts of hormonal health.
