The Claim

In men with oligoasthenozoospermia or low testosterone, right testicular volume demonstrates a stronger correlation with sperm concentration than with sperm motility or testosterone levels.

Source: Right testicular volume is a dominant predictor of testicular function determined by sperm parameters and total testosterone

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In men with low sperm count or low testosterone, the size of the right testicle is more closely related to the number of sperm than to how well the sperm move or the level of testosterone in the blood.

See the scientific wording

Among men with oligoasthenozoospermia or low testosterone, right testicular volume correlates more strongly with sperm concentration than with sperm motility or testosterone levels, suggesting it may be most closely linked to spermatogenesis.

Why this might work

The size of the right testicle shows how many sperm-producing tubes and cells are inside it. More tubes and cells mean more sperm are made, so a bigger testicle matches higher sperm counts.

    In men with low sperm count or low testosterone, the size of the right testicle is a better clue to how many sperm they make than to how well the sperm swim or how much testosterone they have. Bigger right testicle = more sperm production.
