Infertility, zinc and other metals

Abstract

In a nutshellPhysiological but not excessive levels of zinc, copper and other essential metals are required for human fertility, and may also help protect against accumulation of reproductively toxic heavy metals, e.g. lead and cadmium.There is limited RCT evidence for zinc supplements in treating infertility, and very little for other essential metals. Nevertheless, clinicians treating infertility should pay attention to the patient's mineral status.
