Zinc, folic acid supplement does not improve male fertility, NIH study suggests

Dietary supplements containing zinc and folic acid — marketed as a treatment for male infertility — do not appear to improve pregnancy rates, sperm counts or sperm function, according to a study conducted by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health. The study appears in the Journal of the American Medical Association.
