AbstractPrevious research and clinical reports have shown that body weight significantly affects a patient’s fertility status. Underweight, overweight or obese women may experience reduced fertility compared to normal weight women. In Vitro Fertilization (IVF) is used to help infertile couples conceive a child. However, the way abnormal Body Mass Index (BMI) affects infertility is not clear. The objective of this study is to determine the association between BMI and the number of oocytes retrieved during IVF. Data for 136 IVF patients was reported in 2016 at the Reproductive Health Center in Tucson, AZ. The relationship between patients’ BMI and the number of oocytes retrieved was analyzed. The results indicate that BMI affects the number of oocytes retrieved. Overweight patients have fewer oocytes retrieved than that of normal weight patients. Obese patients have even fewer oocytes retrieved than that of both normal weight and overweight patients. As BMI increases, the average number of blastocysts formed decreased, but there was no effect on pregnancy rates and live birth rates. Only one patient with an underweight BMI underwent egg retrieval. Results from this study may be used by IVF physicians and practitioners when advising patients for IVF treatments.
