Harvard research proves that ½ serving of soy daily reduces sperm count and increases infertility in men. Although the relationship between soy and sperm count has not been proven, researchers speculate that soy increases estrogen levels which may interfere with other hormone levels.

"There have been a lot of interest in estrogen and isoflavones in particular and a potential relationship to fertility and other reproductive disorders," said lead researcher Dr. Jorge Chavarro, a research fellow in the department of nutrition at the Harvard School of Public Health.

Moreover, the link between soy and sperm concentration was strongest in men with higher sperm concentrations. Men who have normal or high sperm counts may be more susceptible to soy foods than men with low sperm counts, Chavarro said.
