Can soy impact male fertility?

Talk about soy and lowered sperm concentration may have caught your attention and made you rethink soy in your diet. They certainly alarmed me as the father of a 6-year-old boy who eats soy foods — such as tofu, tempeh, and veggie dogs, burgers — several times a week.
The study, published in Human Reproduction, found that obese men visiting an infertility clinic who reported eating more soy foods (about 1/2 serving per day) had lower sperm concentrations (not counts) or increased ejaculate volume. Could soy’s controversial natural plant estrogens, phytoestrogens, cause hormonal imbalance and infertility? Should I eliminate soy from my boy’s diet and mine?
The most important point is the study did NOT show that soy lowered sperm count, rather, it appeared to increase the volume of semen, which appeared to slightly decrease the relative concentration of sperm. A minimal issue for most guys. I don’t think anyone should be concerned about these findings. The research on soy in men has not found a negative impact on male hormones but rather has suggested a preventive effect in prostate cancer. Which is a good thing! Enjoy the soy!
