Trial Design Double blind
Trial Length 1-6 months
Number of Subjects 37

Age Range 18-29, 30-44
Notes for this study:
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.
