This study is designed to assess the accuracy of Body Mass Index ,Waist Circumference ,Waist Hip Ratio or Waist Height Ratio as a predictor of ovarian response in women undergoing ICSI.

Obesity is an increasingly serious health concern worldwide, and its association with many diseases has been demonstrated. Obesity as it relates to infertility is also being studied All these studies used body mass index (BMI) to determine obesity. Although it is the most commonly used parameter to measure obesity, BMI does not provide an accurate measure of a person's body composition, including body fat.

Almost all studies conducted on this subject used body mass index (BMI) as the measure of obesity; however, using only BMI might be the wrong strategy. Interestingly, some studies on the cardiovascular system found protective effects of BMI and as a result a new term, 'obesity paradox,' emerged. Later studies used waist-to-hip (W/H) ratio and wrist circumference (WC) as a measure of obesity, and showed the exact effect of body fat distribution and obesity on the cardiovascular system
