In a group of infertile men, supplemental zinc was able to increase circulating DHT in all subjects. However, only when the group was divided into men with testosterone below a certain threshold (4.8ng/mL) and above were there modifications in testosterone, fertility, and sperm count; ultimately, men with infertility associated with low circulating testosterone benficially responded to zinc supplementation.
