Glutathione S-transferase (GST) and fluoride may play important roles in idiopathic male infertility, but their effects are still unknown. Our study examined the relationship between GST polymorphisms and fluoride-induced toxicity in idiopathic male infertility and determined the underlying mechanism. Sperm, blood, and urine samples were collected from 560 males. Fluoride levels were measured by a highly selective electrode method, and GST genotypes were identified using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP). Semen parameters, DNA fragmentation index (DFI), mitochondrial membrane potential (MMP), and oxidative stress (OS) biomarkers were statistically assessed at the\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    &lt; 0.05 level. Compared with healthy fertile group, semen parameters, fluoride levels, OS biomarkers, sex hormone levels, and MMP and DFI levels were lower in the idiopathic male infertility group. For glutathione S-transferase M1 (\n                    <jats:italic toggle=\"yes\">GSTM1<\/jats:italic>\n                    [-]) and glutathione S-transferase T1 (\n                    <jats:italic toggle=\"yes\">GSTT1<\/jats:italic>\n                    [-]) or glutathione S-transferase P1 (\n                    <jats:italic toggle=\"yes\">GSTP1<\/jats:italic>\n                    ) mutant genotypes, levels of semen fluoride, OS, MMP, and DFI were considerably higher, and the mean levels of sperm parameters and testosterone were statistically significant in\n                    <jats:italic toggle=\"yes\">GSTM1<\/jats:italic>\n                    (+),\n                    <jats:italic toggle=\"yes\">GSTT1<\/jats:italic>\n                    (+), and\n                    <jats:italic toggle=\"yes\">GSTP1<\/jats:italic>\n                    wild-type genotypes. Both semen and blood fluoride levels were associated with oxidative stress in idiopathic male infertility patients. Elevated fluoride in semen with the genotypes listed above was linked to reproductive quality in idiopathic male infertility patients. In conclusion, GST polymorphisms and fluorine may have an indicative relationship between reproductive quality and sex hormone levels, and OS participates in the development of idiopathic male infertility.\n
