Study on Correlation between BMI,WC and Sperm Quality Parameters of Male Infertility / 现代检验医学杂志

ABSTRACT

Objective To investigate the correlation between body mass index (BMI),waist circumference (WC)and sperm quality parameters of male infertility.Methods 303 cases of male infertility patients including outpatients and inpatients were selected to measure height,weight and WC,and to group according to BMI standards,and sperm quality parameters of each group were detected simultaneously.Results Overweight,obese and severely obese group sperm concentration had very significant difference compared with normal weight group (t = 3.941,3.782,5.632,P 0.05),sperm con-centration and total sperm count decreased with increasing BMI.Low weight group,overweight,obese and severely obese group were higher than normal sperm immobile body recombination,there were significant differences (t = 2.847,8.592, 8.472,5.380,P 0.05).Conclusion Studies showed that the ab-normality of BMI and obesity could cause the changes in sperm parameters which might be an important mechanism of male infertility.
