Recurrent IVF failure refers to the failure of multiple in vitro fertilization (IVF) cycles to result in a successful pregnancy. IVF is a procedure in which a woman’s eggs are harvested and fertilized with sperm outside of the body, and the resulting embryos are then transferred back into the uterus in the hopes of achieving a successful pregnancy. Recurrent IVF failure is typically defined as the failure of three or more IVF cycles, and it can be a distressing and emotionally challenging experience for couples struggling with infertility.
