Australian experts are raising concerns about the widespread use of add-on treatments during in-vitro fertilization (IVF). These add-ons, offered by many clinics, lack substantial evidence demonstrating their effectiveness. The experts are urging IVF practitioners to carefully evaluate whether they should continue offering these treatments, as doing so could be misinterpreted as a guarantee of success. They argue that offering unproven treatments creates an “implicit endorsement of benefit” for patients. The call for caution aims to ensure patients are fully informed about the limited evidence supporting these extra procedures. This comes as the popularity of IVF add-ons continues to grow despite the lack of conclusive research.
