What about soybeans, though? The phytoestrogens in soy protect against cancer, but might they decrease male fertility? Fox News thinks so.
Fact, or fiction? Are you sure—they say they’re fair and balanced.
Fiction, and it’s interesting why. The study did find that soy decreased sperm concentration, but did not significantly affect sperm count. How can you have the same number of sperm, but a lower concentration? Because of larger ejaculate volume. Soy appears to stimulate the prostate gland to produce a larger load of ejaculate fluid, but the actual overall sperm count remains the same.
