The present study is designed to investigate some variables in some types of trace elements such as zinc and magnesium in some different cases of infertility and lack of fertility in men in the northern governorates of Iraq. The study included (75) samples with ages ranging between (25-50) years, of which (60) samples suffered from infertility and lack of fertility, depending on the medical diagnosis made by infertility specialist consultants in Azadi Teaching Hospital in Kirkuk Governorate. The samples were distributed into five groups, each group included (15) sample agencies: the Azoospermia group), the Teratozospermia group, the Oligozoospermia group, the Asthenozoospermia group and the fifth group, which included (15) able healthy people On procreation, which is considered a control group. The study included measuring some biochemical variables for the study samples represented by measuring the level of zinc and magnesium in the blood serum.
The results indicated a significant decrease in the levels of trace elements zinc (Zn) and magnesium (Mg) in the experimental groups: Azoospermia group, Teratozospermia group, Oligozoospermia group, Asthenozoospermia group compared to Control group.
