The Impact of BMI on Fertility: Does Weight Matter?

When it comes to fertility, your Body Mass Index (BMI) plays a pivotal role. In this blog post, we delve into the crucial topic of weight, because being overweight or underweight may lower your chances of achieving pregnancy. And while BMI is not the sole diagnostic tool we use, it serves as a helpful overall measure of general health.

The BMI Connection: A Simple Calculation

So what exactly is BMI? It’s a simple yet powerful number that reflects your weight in relation to your height. BMI is not a perfect indicator of health — for example, BMI does not differentiate between weight from fat or muscle. However, it is a general index that is clinically helpful for determining population risk. This BMI calculator from the National Institute of Health can help you determine your own BMI.

Too Low, Too High, or Just Right? The Impact of BMI on Fertility.

Research has shown that as people’s weight goes up (a BMI above 30), the chances of getting a pregnancy and keeping a pregnancy go down. Also, with BMIs above 35, health complications during pregnancy itself begin to rise, along with a higher risk of complications during procedures such as IVF.

Let’s break it down further:

• Underweight: If your BMI is too low, it can disrupt hormonal balance, affecting ovulation and menstrual regularity.
• Overweight or Obese: Excess weight can lead to insulin resistance, inflammation, and hormonal imbalances. These factors impact egg quality, embryo development, and implantation.
• Optimal Range: Strive for a BMI within the healthy range of 18.5–24.9.

Because the IVF process includes a surgical procedure to remove eggs from the ovaries under anesthesia, and because the anesthesia risks increase substantially with a higher BMI, in our clinic we have a BMI limit of 40 kg/m2 to do IVF.  This limit is due to the fact that the cardiopulmonary complications of anesthesia are markedly increased with a BMI over 40 kg/m2. While our doctors can certainly offer an IVF consult to talk about IVF if your BMI is over 40, we would not start the IVF process until your weight is at this threshold.
