The Claim

Men with type 2 diabetes mellitus have significantly reduced average testicular volume compared to healthy men, independent of obesity status.

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.

Description
1 study reviewed
In plain English

Men with type 2 diabetes mellitus have smaller testicles on average than men without the disease, regardless of whether they are obese.

See the scientific wording

Men with type 2 diabetes mellitus have significantly reduced average testicular volume compared to healthy men, regardless of obesity status, indicating a potential link between the disease and structural testicular changes.

Why this might work

High blood sugar damages the energy-producing parts of cells in the testicles, causing them to produce less testosterone and shrink over time.

  1. Study: Type 2 diabetes mellitus but not overweight/obesity reduces testicular volume and endocrine function in men

    Men with type 2 diabetes were found to have smaller testicles than men without diabetes, even if they had the same weight. This suggests diabetes might affect testicle health directly, not just because of being overweight.
