IVF helps you get pregnant, but the pregnancy decides for itself how its going to go. Studies have shown that babies from IVF tend to have slightly more problems, like placenta issues, smaller size babies, slight increased risk of abnormality and prematurity. However, it is difficult to say that IVF is the cause of these as IVF patients tend to be older and tend to have higher risks in pregnancy. The chances of successful IVF is approximately 30%. Depending on the ages of the couples, they should try for at least 6-12 months before seeking IVF treatment.
