Body Mass Index (BMI) Calculator

Patients with a normal body mass index (BMI, between 20 and 26) have an up to 10% higher chance of becoming pregnant after receiving fertility treatment.

A high BMI can be just as disadvantageous as a BMI under 20.

There is disagreement about the specific power of the calculated BMI value. Especially because the entire body mass is simply used and there is no distinction between muscle and fatty tissue. So trained people have a higher body mass index.

Nonetheless, the BMI provides an easily determinable guideline for the body fat percentage.
