Liposuction is unlikely to adversely affect your chances of conceiving. Although Liposuction leads to reduction in weight and fat mass it does not confer health benefits like redcution in risk of coronary heart disease or improve insulin sensitivity in diabetic patients. It should be remembered that Woman with high BMI (body mass index ) and difficulty conceiving are always advised to lose weight, especially if they have associated condition like Polycystic ovarian syndrome. Hope this helps!
