Introduction: Rising levels of obesity pose a public health problem globally. Approximately 1.6 billion adults were overweight by having (BMI 25-30 kg / m2) and 400 million (BMI __ampersandsigngt; 30 kg / m2) in 2005 globally. In general, obese women have lowered oocyte production, lower developmental output, and poor clinical experiences while undergoing assisted reproductive (IVF) treatment. The aim of this study was to perform a preliminary assessment of the influence of BMI on quality oocyte outcome i.e. finally impact on IVF outcome in these patients and to provide data for future trials in this field. Aim and Objectives: To study the effectiveness of body mass index on oocyte quality in subfertile females. Materials and Methods: This study is done in Wardha test tube baby centre AVBRH (SAWANGI) WARDHA Relevant data on the demographics and treatment history of 40 subfertile female patient as well as the indications for IVF treatment were recorded. Observation and Result: Patient in 21-24 BMI group 80% of them found with increased metaphase II stage oocyte retrieval. In BMI group 25-29, 45% patients observed with increase in metaphase II oocyte. In the BMI group of 30-34 only one out of 6 patients observed with increased oocyte quality remaining 5 showed negative responses. Conclusion: Increase in BMI in ovulatory women may be inversely proportional to affect the outcome of treatment with ovulation induction and finally on the likelihood of pregnancy.
