Objectives The aim of the study to evaluate the effects of metabolic syndrome on semen quality.
Methods Semen samples were collected from 28 males (mean age 33.64 ± 7.42 years) had the features of the metabolic syndrome according to the IDF2005 definition. 20 healthy men aged compared were enrolled as control. According to WHO (1999) guidelines, semen samples were analysed for volume, sperm concentration, total sperm count, motility, vitality, and leucocyte concentration. Serum samples were prepared for sexual hormone test.
Results Ejaculate volume, sperm concentration (in million per millilitre), total sperm count (in million), and leucocyte concentration were compared between two groups. Serum testosterone level was compared also. Percentage of motile spermatozoa (46.01 ± 11.55% vs 57.60 ± 9.33%, p <0.05) were significantly reduced in metabolic syndrome group. 4 men with obesity (BMI > 30) had significantly lower sperm concentration and total sperm count in comparison to others whose BMI below 30 (34.60 ± 7.49% vs 47.91 ± 11.08%, p <0.05).
Conclusions Metabolic syndrome was linked to subfecundity in the absence of leucocytospermia. Male obesity has been associated with abnormal sperm characteristics.
