It is said that being overweight affects the chance of getting pregnant after IVF, and further that the probability is high that a possible pregnancy will end in abortion. In addition, it is claimed that the pregnancy involves great risk for mother and child. But is this true?

Many clinics do not offer treatment to women with a BMI over 30. The vast majority of people who are overweight become pregnant spontaneously and have completely normal pregnancies. It is also not seen that being overweight results in reduced sperm quality in men. However, increased weight increases the likelihood of developing PCOS. This is a condition in which the maturation of eggs is affected, and thus ovulation is absent. PCOS is the most common cause of missed pregnancies in women. Fortunately, this condition is one of the easier to treat.

Klinikk Hausken analyses all factors that may have an impact on the outcome on an ongoing basis. When it comes to weight, only those with a very low BMI show a reduced chance of succeeding with IVF treatment. The figures show that the chance of pregnancy actually increases with increasing BMI. There is also no increased risk of miscarriage.

What about pregnancies? The vast majority have normal pregnancies and births, but there is an increased incidence of pregnancy-induced diabetes. Klinikk Hausken, therefore, has no general BMI limit for offering IVF treatment. With us, for everyone receives an individual assessment, and together with the couple, we find the best solution.

This does not mean that the general increase in obesity seen in society is without problems. It is important to put in place measures to combat this development. But setting boundaries to help women who are not getting pregnant due to being overweight is not the way to go.
