Background: Trace elements are the basic components of biological enzyme system or the structural components of very low concentration bioactive components. There are a number of trace elements in foods, such as iron, iodine, fluorine, copper and zinc, as well as chromium and cobalt. Other trace elements include tin and vanadium. Nickel and silicon are two examples of metals. Some of the trace elements are toxic to reproductive health at high doses. Trace amounts of these substances are rarely used for various physiological functions of the body. Many metal ions (copper, arsenic, cadmium, chromium, nickel, lithium vanadium, lead, and mercury) have many adverse effects on reproduction and development, fertility of men and women, abortion, and deformity. Exposure timing and duration, metal ions' distribution and accumulation in various organs, and interference with specific developmental processes; all have an impact on the consequences of metal ions. Objective: To assess the trace element's role in male infertility especially the role of zinc. Conclusion: Trace elements are very important for the sperm production and quality and could affect the male fertility by one way or another.
