A review published in June 2026 assessed the evidence behind IVF “add-ons”: procedures or medicines offered alongside standard treatment.

The researchers examined clinical trials and found that several commonly offered interventions had insufficient evidence of improving pregnancy or live-birth outcomes, or showed no clear benefit. Some approaches showed possible signals of benefit, but the evidence remained weak or limited.

Better information for decisions

The findings support transparent conversations about benefits, risks, costs and evidence quality. They do not mean that every add-on is ineffective; rather, they highlight the importance of distinguishing reasonably supported options from interventions that remain experimental.
