AbstractThis study aims to ascertain the associations between serum leptin levels and metabolic syndrome and semen parameters in patients with infertility. A total of 200 patients who were diagnosed as primary infertility in our hospital were enrolled in this study, and they were divided into MetS group and non-MetS group. About 30 healthy men were enrolled as the control group. The general information, blood lipids, reproductive hormones and semen parameters were collected. We used the Student t test, the Chi-square test, the Kruskal-Wallis test, and the spearman correlation analysis to analyze their relationships. BMI, glucose, TG, follicle-stimulating hormone (FSH), and leptin were significantly higher in MetS infertile patients (P < .001; P < .005; P < .001; P < .001; and P < .001, respectively). While T and high-density lipoprotein (HDL) were significantly lower in MetS infertile patients (P < .01, and P < .001, respectively). Leptin was correlated with sperm progressive motility (R = -0.312, P < .01), and normal morphology (R = -0.458, P < .001). Moreover, sperm concentration was correlated with FSH (R = -0.268, P < .001) and inhibin B (R = 0.401, P < .001), and normal morphology was correlated with HDL (R = 0.233, P < .001) and TG (R = -0.182, P < .01). In primary infertile patients, sperm normal morphology were found to be depressed and related to MetS. Leptin was increased in patients diagnosed with MetS and associated with semen parameters.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
