Study the Effect of Increasing Body Weight on Infertile Men
Abstract
Background: Male infertility affects due to a variety of problems including varicocele, prostate cancer, systemic disorders, and genetic factors. There is no underlying explanation for primary and secondary infertility. in present study, data at the impact of obesity and over-weighting on seminal fluid characteristics and men fertility are collected. The goal of this research turned into to assess the effect of weight problems on semen characteristics in infertile men.
Patient and method: A cross-sectional study was conducted on eighty one infertile men who met inclusion criteria. patients age, duration of infertility and type of infertility was taken. Seminal fluid results were collected and sperm concentration, volume, progressive motility, total motility and normal sperm morphology were assessed in accordance with WHO 1999 criteria. For each patient weight and height were measure and patients were divided by BMI into normal weight (BMI: 18.5–24.9 kg/m2, n = 23), overweight (BMI: 25–29.9 kg/m2, n = 28) and obese (BMI: ≥30 kg/m2, n = 30). Seminal fluid parameters were compared among the three groups.
Results: Mean age, Type and duration of infertility in these three groups were not different significantly. although Sperm concentration was lower in obese men but it did not differ significantly from those of normal weight and overweight infertile men (P > 0.05). Type of infertility whether it is primary or secondary also wasn't significantly different. But Sperm progressive motility, total motility and normal sperm morphology were significantly different among the three groups. And was more significant in those obese and overweight than patients with average weight.
Conclusion: Our findings suggest that obesity and overweighting have influence on sperm motility and normal morphology in infertile men. But have no effect on sperm concentration and volume.
