The Claim
A right testicular volume of less than 15 mL is associated with a 2.79-fold increased odds of low testicular function in men undergoing fertility evaluation, with a sensitivity of 66.7% and specificity of 62.4% for identifying impaired sperm and hormone parameters.
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 a right testicle smaller than 15 mL are more likely to have reduced sperm production and hormone levels during fertility testing, as measured by specific diagnostic thresholds.

A right testicular volume of less than 15 mL is associated with a 2.79-fold increased odds of low testicular function in men undergoing fertility evaluation, with a sensitivity of 66.7% and specificity of 62.4% for identifying impaired sperm and hormone parameters.
A smaller right testicle means there are fewer sperm-producing tubes and fewer hormone-producing cells inside, which directly lowers sperm count and testosterone levels.
What the research says
1 studyIf a man’s right testicle is smaller than 15 mL, this study shows he’s nearly three times more likely to have low sperm count or low testosterone, and this size check correctly spots the problem about two-thirds of the time.
