09 Jan 2020 --- Men should no longer be advised to take zinc and folic acid supplements as a way to boost their fertility, according to a new study. A team of researchers at Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health, found that the ingredients – often marketed toward men struggling with infertility – do not appear to improve pregnancy rates, sperm counts or sperm function. However, one fertility supplement company is unconcerned by these findings, noting the number of conflicting studies.
