Men all over the world are losing testosterone every year, and the amount of testosterone is exponentially decreasing every generation. We’ve compiled a number of medical studies from the United States and Europe that show there is a generational decrease of testosterone (T) levels in men.
This means on a macro level, men are living increasingly unhealthier lives which affect their bodies and the ability to produce ideal levels of testosterone.  This is happening because of social, environmental, and behavioral reasons that are making men lose Testosterone, the biological element that makes men healthy and masculine.
This downward trend may lead to serious chronic health and mental problems associated with low testosterone for men throughout the world. Depression may be one of the most damanging symptoms of low-t, we’ve also put together a commplete list of causes and symptoms associated with Low-T.

Men are Losing 1% Testosterone Every Year

A 2007 study has found that the levels of testosterone in men have dropped by 1% every year since 1980. The study was published in the Journal of Clinical Endocrinology and Metabolism, and it details the results from testing 1,532 men, while also listing the main causes for low-testosterone :

Low-serum T has been associated with numerous age-related adverse health conditions including abdominal obesity, diabetes, and prediabetic states (such as insulin resistance, impaired glucose tolerance, and metabolic syndrome), dyslipidemia, low bone and muscle mass, impaired sexual function, depressed mood, frailty, and decreased quality of life (10–12). T decline across the life span therefore represents an issue of great concern for public health, but large studies of within-person decreases in T are rare.

Danish Study: Testosterone Levels Dropped in Men from 1920s to 1960s

According to a study from a top reproductive health hospital in Denmark, medical testing on 5,000 Danish men showed that “men born in the 1960s have on average 14% lower T levels than males from the 1920s”, this first covered by a nordic news outlet Ice News (see their report by clicking here). The article from 2010 also goes on to point out the decrease in levels of the testosterone-binding protein SHBG by 26% in the same period.
One men’s health specialist and Urologist Dr. Peter Lyngdorf, lists possible causes of decrease in T levels as partly due to the use of pesticides in foods and unhealthy lifestyles.
We’ve put together an exhaustive list on causes of low-t, available on our website.
