Zinc and folic acid are touted as a dietary Supplement for the treatment for male infertility in a desire to have children, although this effect has not been demonstrated in studies to date clearly. A new study by the University of Utah, comes to the conclusion that the ingestion of these nutrients does not improve the semen quality and fertility.
2.370 couples to undergo a fertility treatment, and were divided into two groups, in which the men for six months with either daily Placebo or a Supplement with folic acid and zinc revenues. Contrary to expectations, there were no differences in the number of births in the two groups, and also the total number of sperm, their motility and shape differences. Men who had taken zinc and folic acid, complained of frequent side effects, such as abdominal pain, Nausea, and vomiting. They also had a higher proportion of broken DNA within the sperm, which can contribute to male infertility.

Dr. med. C. Matthew Peterson, a reproductive endocrinologist at the University of Utah, commented on the results: "This large, well-controlled, randomized study shows that food supplements such as zinc and folic acid can improve the probability of a pregnancy of a couple and cause side effects that are beneficial." He does not recommend that men of all ages should eat a healthy diet to fertility to maintain the intake of supplements he thinks are necessary.
