The relationship between semen quality and trace element levels in seminal plasma and miR-184 levels in seminal vesicles of male infertility patients / 实用医学杂志

ABSTRACT

Objective Explore the relationship between semen quality and trace element levels in seminal plasma,as well as miR-184 levels in exosomes of male infertility patients.Methods 155 male infertility patients in our hospital from January 2022 to July 2023 were selected as the infertility group,and another 155 male patients with normal physical examination during the same period were selected as the normal group.Compare the general information,semen quality parameters,trace elements,and miR-184 levels in exosomes between two groups,and analyze the correlation between male infertility patients and the above laboratory indicators through Spearman rank correlation analysis.Results The sperm concentration,total sperm motility(PR + NP),forward motility sperm(PR),average curve velocity,average linear velocity,average path velocity,and average lateral amplitude of sperm head(ALH)in the infertile group were lower than those in the normal group(P<0.05);The levels of Zn,Mg,and Ca in the infertile group were lower than those in the normal group,while the levels of Cu,Pb,and relative expression of miR-184 were higher than those in the normal group(P<0.05);The levels of Zn and Cu elements in male infertility patients are positively and negatively correlated with sperm concentration,total sperm motility(PR+NP),and forward motility sperm(PR),respectively.The levels of Pb elements are negatively correlated with the average lateral amplitude of sperm head(ALH),and P<0.05.The relative expression level of miR-184 in male infertility patients is negatively correlated with sperm concentration,total sperm motility(PR + NP),forward motility sperm(PR),and average sperm curve velocity,with P<0.05.Conclusion The quality of semen in male infertility patients is closely related to the levels of trace elements in semen and miR-184 levels in exosomes.
