The Claim
The prevalence of low testosterone in men increases with waist circumference, showing a gradient from 8% in men with waist circumference ≤93 cm to 44% in men with waist circumference ≥110 cm, indicating a dose-response relationship between abdominal obesity and testosterone deficiency.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Men with larger waist sizes have a higher rate of low testosterone. Among men with a waist size of 93 cm or less, 8% have low testosterone; among men with a waist size of 110 cm or more, 44% have low testosterone.
See the scientific wording
The prevalence of low testosterone is strongly linked to waist circumference, with a clear gradient from 8% in men with waist circumference ≤93 cm to 44% in those with waist circumference ≥110 cm, indicating a dose-response relationship between abdominal obesity and testosterone deficiency.
Excess fat around the waist releases chemicals that cause ongoing body-wide inflammation and make the body less responsive to insulin. These changes signal the testes to produce less testosterone and reduce the signals from the brain that tell the testes to make testosterone.
What the research says
1 studyStudy: RETHINKING LOW TESTOSTERONE IN OLDER MEN: ASSOCIATION WITH OBESITY RATHER THAN AGING.
The study found that men with bigger waistlines are much more likely to have low testosterone—those with a waist over 110 cm are more than five times as likely to have low testosterone as those with a waist under 93 cm. So yes, bigger waist = lower testosterone.
