The Claim

Obesity and short stature are associated with reduced circulating levels of testosterone, dihydrotestosterone, and estradiol in Australian men, indicating that body composition is a major determinant of these androgen and estrogen levels independent of age.

In plain English

Australian men with obesity or short stature have lower levels of testosterone, dihydrotestosterone, and estradiol in their blood, and this is linked more to their body composition than to their age.

See the scientific wording

Obesity and short stature are associated with reduced androgen status in Australian men, indicating that body composition, not just age, is a major determinant of circulating testosterone, dihydrotestosterone, and estradiol levels.

Why this might work

Extra fat tissue converts male hormones into female hormones, and less of the protein that carries hormones in the blood is made, so less active testosterone and estradiol circulate in the body.

  1. Study: Age-specific population centiles for androgen status in men.

    In Australian men, being heavier or shorter is linked to lower levels of key male hormones like testosterone, even when accounting for age. So, body size matters just as much as how old you are.
