Weight and Fertility

Body mass index and its effect on in vitro fertilization pregnancy rates

Background
A woman's weight can affect her fertility. We know that at both extremes, very thin and obese, that there can be disruption of the normal process of regular, consistent ovulation. Anovulation can often result. Medications can be used to induce ovulation in these women in an attempt to become pregnant.
Body mass index, or BMI, is an index of a person's relative "skinniness or fatness". The BMI factors in a person's weight as well as their height to give an overall "index". A high BMI indicates obesity.

bullet A standard medical definition of "normal" body weight is a BMI of about 18.5 - 24.9

bulletA BMI under 18.5 indicates that the person is "underweight"

bullet A BMI of 25.0 - 29.9 indicates that the individual is "overweight", but not obese

bulletA BMI over 30 indicates obesity

bulletA BMI over 40 indicates extreme obesity

Obesity is associated with increased risk for several serious disease processes. Extreme obesity is associated with a dramatically increased risk for many serious diseases. The web site weight.com is a good place to start learning more about those risks, as well as weight loss issues, etc.
Body mass index is calculated with this formula:
weight (in kilos) divided by height (in meters) squared
Therefore, if someone weighs 100 kilos and is 1.8 meters tall, their BMI is 100 divided by 1.8 X 1.8 = 100/3.24 = 30.9
To convert from pounds to kilos, take the weight in pounds and divide it by 2.2
To convert from inches to meters, take the height in inches times 0.0254
