Weight & BMI

Weight

Studies have shown that being overweight and fertility negatively affect each other. So in other words; being overweight can be a reason why you can’t get pregnant.
Being overweight but certainly also underweight can change your hormonal balance. This disrupts the function of the ovaries. You can notice this because your menstruation becomes more irregular and sometimes even stays away. You may also not notice your period but you can be less fertile because your weight is too high or too low.

What constitutes a good BMI

The heavier you are, the less fertile you are. This applies not only to women, but men should also watch their weight.
At a BMI between 21 and 29, the chances of pregnancy are greatest because this is when an egg matures better and a fertilized egg can develop better.
Every BMI unit above that decreases the chance of pregnancy by 4-5%.
At a BMI of 35, the chance of pregnancy is about 26% lower; at a BMI of 40, the chance is 43% lower.
