[ 6 – 8] The relative risk of anovulatory infertility is 2.7 (95% CI, 2.0-3.7) in women with BMI≥ 32 kg/m 2 at age 18, [ 9] while in ovulatory but subfertile woman the chance of spontaneous conception decreases by 5% [ 10] for each unit increase in the BMI.

Women: 100 pounds (45 kg) for the first 5 feet (1.52 m) of height; five pounds (2.3 kg) per inch (2.5 cm) thereafter. Example: A woman who is 5-foot-6 could appropriately weigh 130 pounds, or 117 30 years: 26 - 27 BMI. 40 years: 27 - 28 BMI. 50 years: 28 - 29 BMI. 60 years: 27 - 28 BMI. As can be seen, the normal ranking changes over time and, around the age of 57, it actually begins to drop again. This simply means there is no magic number, weight-wise that could cover a normal level for women as the BMI will change you age. For women, the ideal body fat is 20 to 21 percent. The average American woman has about 22 to 25 percent body fat. For men, the recommended amount of body fat is between 13 and 17 percent. The average American man has about 17 to 19 percent body fat.
