Infertility is more complicated than it first appears. There are levels, phases, and complications. Secondary infertility is a problem that occurs when a couple conceives naturally the first time and then struggles to conceive again. Even after several attempts, IVF and other fertility treatments look like a likely and successful option when spontaneous conception becomes challenging. This raises a crucial question: Is IVF more successful following a natural birth? A common misconception is that high IVF success rates are inevitably guaranteed by a \"successful natural conception\" in the past. While some of it may be true, we must acknowledge that IVF is a very complicated process that is impacted by many different circumstances.
