Body mass index (BMI) is a risk factor that influences semen quality and reduces male fertility. The aim of this study was to determine the impact of BMI on semen parameters in infertile men. A total of 446 infertile men, the study population was divided into four groups depending on their BMI, underweight (<18.5 kg/), normal weight (18.5-24.99 kg/m2), overweight 25-29.99 kg/m2), and obese >30.0 kg/. Semen parameters (PH, volume, concentration, total semen count, vitality, morphology and motility) were compared across the four BMI groups. The mean of age was 41.91±6.39, the mean infertility duration was 4.92±3.28, 351, (78.7٪) had primary infertility and 95(21.3٪) had secondary infertility. The mean BMI was 29.38± 4.85 and the most of patients 45.2٪ were obese. This study has found evidence of an association between BMI and semen parameters (sperm concentration, total sperm count, motility, and vitality) and no correlation between semen volume, morphology and BMI. This study shows as expected that obesity and overweight do have a negative impact on male infertility and as a consequence they should be taken in consideration when treating couple who suffer from infertility especially if the male partner has a BMI higher than 25. More studies in our region are needed in order to asses the other effect obesity has on the hormonal profile and the efficient of the treatment used.
