The Claim
Higher body weight, BMI, and body surface area, as well as shorter stature, are associated with lower serum levels of testosterone, dihydrotestosterone, and estradiol in Australian men aged 35–100 years.
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.
In Australian men aged 35 to 100, higher body weight, higher BMI, larger body surface area, and shorter height are linked to lower levels of testosterone, dihydrotestosterone, and estradiol in the blood.
See the scientific wording
Higher body weight, BMI, and body surface area, as well as shorter stature, are associated with lower serum levels of testosterone, dihydrotestosterone, and estradiol in Australian men aged 35–100 years, suggesting that adiposity and body size are key correlates of androgen status.
Fat tissue converts testosterone into estrogen, and also binds to sex hormones so they cannot be used by the body, leading to lower levels of active testosterone and estrogen in the blood.
What the research says
1 studyStudy: Age-specific population centiles for androgen status in men.
In Australian men, the study found that heavier and shorter men tend to have lower levels of key male hormones like testosterone, DHT, and estradiol — meaning body size and weight are linked to hormone levels.
