The impact of trace elements, especially zinc, selenium, copper, and magnesium, on male fertility has gained great interest and significance. Increased oxidative stress and altered trace element levels are probable etiological factors underlying male reproductive dysfunction and infertility. The present study focused on the evaluation of seminal oxidative markers, such as reactive oxygen species (ROS), malondialdehyde (MDA), and total antioxidant capacity (TAC), and trace element levels in the normozoospermic fertile control group (n = 40) and asthenozoospermic infertile group (n = 30). Semen from infertile men exhibited significantly higher ROS and MDA levels accompanied with significant decline in TAC and trace element (zinc and magnesium) levels. Furthermore, a significant correlation was observed between trace elements and oxidative markers with sperm motility. The current study revealed increased lipid peroxidation and oxidant-reductant imbalance that leads to deterioration of semen quality and male infertility. Thus, oxidative stress and trace elements can be considered important biomarkers of male infertility. Measurement of seminal oxidative stress with conventional seminological parameters must be integrated in fertility assessment from early stages to ensure healthy semen characteristics and fertility in men.
微量元素,尤其是锌、硒、铜和镁,对男性生育能力的影响已引起了极大的关注并具有重要意义。氧化应激增加和微量元素水平改变可能是男性生殖功能障碍和不育症的潜在病因。本研究聚焦于评估正常精子形态的生育对照组(n = 40)和弱精子症不育组(n = 30)的精液氧化指标,如活性氧(ROS)、丙二醛(MDA)和总抗氧化能力(TAC),以及微量元素水平。不育男性的精液显示出显著更高的ROS和MDA水平,同时TAC和微量元素(锌和镁)水平显著下降。此外,观察到微量元素与氧化指标和精子活力之间存在显著相关性。当前研究揭示了脂质过氧化增加和氧化还原失衡,这导致精液质量恶化和男性不育。因此,氧化应激和微量元素可被视为男性不育的重要生物标志物。在生育评估的早期阶段,必须将常规精液学参数与精液氧化应激的测量相结合,以确保男性精液特征健康和生育能力正常。
