We aimed to determine the impact of metabolic syndrome (MetS) on reproductive function in men with secondary infertility, a condition that has received relatively little attention from researchers. Complete demographic, clinical, and laboratory data from 167 consecutive secondary infertile men were analyzed. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI; categorised 0 vs 1 vs 2 or higher). NCEP-ATP III criteria were used to define MetS. Semen analysis values were assessed based on the 2010 World Health Organization (WHO) reference criteria. Descriptive statistics and logistic regression models tested the association between semen parameters and clinical characteristics and MetS. MetS was found in 20 (12%) of 167 men. Patients with MetS were older (P < 0.001) and had a greater BMI (P < 0.001) compared with those without MetS. MetS patients had lower levels of total testosterone (P = 0.001), sex hormone-binding globulin, inhibin B, and anti-Mόllerian hormone (all P ≤ 0.03), and they were hypogonadal at a higher prevalence (P = 0.01) than patients without MetS. Moreover, MetS patients presented lower values of semen volume, sperm concentration, and sperm normal morphology (all P ≤ 0.03). At multivariate logistic regression analysis, no parameters predicted sperm concentration, normal sperm morphology, and total progressive motility. Our data show that almost 1 of 8 White-European men presenting for secondary couple's infertility is diagnosed with MetS. MetS was found to be associated with a higher prevalence of hypogonadism, decreased semen volume, decreased sperm concentration, and normal morphology in a specific cohort of White-European men.
