Why you might see this term
Ask what outcome an add-on is intended to improve, what evidence applies to people like you, and what risks and costs it adds.
What to keep in mind
Newer or more expensive does not automatically mean better. Check the HFEA’s current evidence information rather than assuming an extra improves live-birth chances.
