Effect of Body Mass Index on sperm and semen parameters for infertile Patients

Out of 130 specimens of seminal fluid were collected from patients suffering of infertility , after abstinence of 3-5 a period of days from Fertility Center Laboratories Al – Saader Medical City at Al-Najaf Province ,the study continuouse from 172011 to 192011. The aims of this study at clarifying the role of the body weight on infertility patients suffering from Normospermia , Asthenospermia ,Oligospermia ,Azoospermia ,and Teratospermia ,by calculated the Body Mass Index (BMI) for each patients as kg m2 which classify to normal weight and over weight .The results of this study revealed an increased of percentage Oligospermia percent with BMI of patients in comparison to that of other infertility types , as well as ,it showed clear effect of increase BMI to Normospermia and Asthenospermia patients which it significant decrease (P 0.05) of sperm motility, morphology and concentration of sperm compared between normal and over weight. The study results had revealed significant decrease (P 0.05) of sperm concentration , liquificative time of semen, motility and normal sperm morphology of Oligospermia suffering for increase BMI (over weight). In Azoospermia and Teratospermia patients, the results of sperm and semen parameters revealed a non significant (P 0.05) correlation ships between normal and over weight.It can be concluded that BMI correlated with reproductive physiology through increase of infertility men percent , when infertile men with high BMI typically are found to have an abnormal semen analysis represented by decrease in sperm concentration, decrease in sperm motility percent , as well as, increase of abnormal forms of spermatozoa
