Why are today's men losing 30% of their testosterone when compared to men as recently as the turn of the 21st century? A number of lifestyle choices and environmental factors apply. Let's stick to the factors that can be addressed:
- Obesity/Sedentary lifestyle. This should be the first thing that we address for any man who has lost his vigor and virility. A 2007 study found that every 1% increase in BMI led to a 2% decrease in testosterone. Waist circumference is still the top predictor for testosterone deficiency.
- Phthalates. These plastic softening chemicals are found nearly everywhere due to microplastic exposure and our societal reliance on plastic packaging. Multiple studies have led researchers to find that exposure to phthalates have led to anywhere from 10%-34% reduction in testosterone depending on the study. The damage is not settled when it comes to plastics and endocrine disruptors, it's clear that research on phthalates continues to show more damaging correlations as it becomes more widely studied.
- Lack of Sunlight. Several studies have shown that a lack of vitamin D3 is associated with lowered testosterone levels. Frankly, a lack of vitamin D3 is associated with so many adverse effects that it should be supplemented regardless of your daily sunlight exposure.
The prescription is simple. Get outside, get active, eat healthy, and minimize plastic.
The alternative is TRT and Viagra slowly reducing your body's ability to create it's own androgens.
