Complications
Repeated implantation failure usually describes several transfers of good-quality embryos without pregnancy. Assessment looks at the uterine cavity, thyroid and other medical factors, sperm quality, and embryo chromosomes. Many add-on tests and immune treatments are marketed for this situation with limited evidence, so weigh cost and evidence carefully.
Also known as: repeated implantation failure, RIF, failed transfers
