The Relationship Between the Body Mass Index and the Controlled Ovarian Stimulation Outcomes
AbstractWhen assessing the impact of body mass index (BMI) values on controlled ovarian outcomes, high BMI tips the balance regarding negative impact. Although not all studies agree, it seems that both intermediary and definite endpoints are offset, and the effect is progressively more significant with increasing BMI. In addition, evidence suggests that oocyte quality and endometrial receptivity are lower in overweight and obese patients. Perfecting how increased weight is quantified and unifying definitions of parameters assessed emerge as ways in which a more concise view of the impact of BMI on in vitro fertilization (IVF) procedures could be achieved. The unifying viewpoint is that weight interventions could improve natural and assisted conception results and assure a safer pregnancy for both mother and child. Still, how weight loss could be achieved, especially in these women to whom time pressure is added, remain to be refined.
