Sometimes it takes two or more IVF cycles to get a successful outcome. While this may hurt you physically, emotionally, and mentally, it can help to realize that you are not alone in your struggle, that there is help available from decades of experienced fertility specialists, and that IVF failure is not your fault. For each IVF cycle, your doctor will advise you on what caused the miscarriage, and how you can use this information to improve your chances of success if you decide to have IVF again. A few tests that can be done to find the root of IVF failure include: 1. Immune test 2. Infection testing 3. Cervical gland examination 4. Karyotyping 5. Sperm test
