What tests should be done after recurrent implantation failure?

IVF failure is usually multifactorial rather than caused by one single mistake. Possible contributors include egg quality, sperm factors, embryo chromosome status, lab development, endometrial receptivity, transfer timing, uterine abnormalities, or the normal biological attrition that happens even in good cycles. The most useful next step is a structured post-cycle review to identify where the drop-off likely happened and whether the next plan should change.
