BMI Calculator for IVF: A Key Tool in Your Fertility Journey

A woman’s weight plays a determining role in her IVF success. Being overweight can increase your chances of health issues including diabetes, heart disease, and thyroid dysfunction which can greatly impact your fertility and in turn your fertility or IVF treatment. Similarly, being underweight may also deprive your body of the required nutrients for a successful pregnancy. 

This is one of the main reasons why physicians recommend checking body mass index or BMI when trying to conceive through IVF treatment. In this article, we will explore the importance of BMI for women who are trying to conceive either naturally or with fertility treatments including IUI or IVF.

What is Body Mass Index (BMI)?
