Which is more painful IUI or IVF?

Both IUI and IVF can be uncomfortable, but IVF is often more painful due to egg retrieval. It's best to check with your doctor for personalized advice. IUI involves inserting sperm directly into the uterus, which is generally less invasive and less painful than IVF. IVF involves multiple injections and a surgical procedure to retrieve eggs. The egg retrieval process can cause cramping and soreness.
