|Abstract:||Several studies have suggested a population-wide decline in the quality of human semen during the past three decades, but the mechanism remains unclear. It was proved that damage to the DNA of germ cells would lead to mutation, and 8-hydroxydeoxyguanosine (8-OHdG), one of the major products of oxidative damage to DNA, may serve as one of the important factors to affect the sperm quality. In the present paper, 67 semen samples were collected to analyze the sperm quality (density, sperm number, motility, normal head, etc.), and 8-OHdG was measured in DNA isolated from the same sperm samples. The results showed that a significantly inverse correlation exists between 8-OHdG/dG(deoxyguanosine) and sperm density (r = -0.358, p = 0.004), and between 8-OHdG/dG and sperm number (r = - 0.389, p = 0.01). The results indicate that endogenous oxidative DNA damage could affect sperm quality and subsequently increase the risk of genetic defects.|
