Body Mass Index (BMI) is a measurement that uses your height and weight to determine if your weight is within a healthy range. Current NHS guidelines suggest the ideal BMI is in the 18.5 to 24.9 range.
We understand that weight can sometimes be a sensitive topic, especially when navigating potential fertility challenges. In this blog, we look at some reasons BMI can affect IVF and help patients understand the importance of maintaining a healthy BMI.
So, why does BMI matter when considering IVF?
A high BMI can influence several aspects of IVF treatment, from the amount of medication needed to your ovarian reserve, and in some cases, the number of cycles needed. That’s why, to increase the chances of success and ensure your safety, Essential IVF has a BMI range of 18 to 32.
Typically, women with a BMI over 32 require a higher dose of medication to stimulate their ovaries and may take longer to respond to treatment.
But it is not just a woman’s BMI that can affect the chances of successful conception. Men who are overweight may also experience issues with their sperm, including reduced motility and lower sperm count.
Can people with a high BMI still get pregnant?
You can still get pregnant if you have a BMI lower or higher than the recommended range. However, the chances are likely to be reduced. That’s why, to be eligible for Essential IVF®, we recommend that the female undergoing treatment meet the following criteria:
- Under 37 years old
- With a BMI between 18 and 32
- AMH between 10 and 35
- Regular menstrual cycles
- No underlying health conditions
How else can I be healthy for IVF?
A healthy BMI is just one way to increase your chances of conception. In addition, you can make several other lifestyle choices to improve your overall health. This includes keeping a balanced diet with plenty of fruit and vegetables and avoiding smoking and alcohol during treatment to improve your chances of having a baby.
