IVF helps families expand every year, but rare mishaps force people to make agonizing choices. IMPACT x Nightline: "Switched Before Birth" streams on Hulu this Thursday.

Summary

Several women are suing fertility clinics after devastating IVF mix-ups led them to carry and give birth to babies who were not biologically theirs.

Krystena Murray, a single mother from Georgia, discovered after delivery that her son was not related to her and later lost custody to his biological parents.

The Cardinale family in California experienced a similar embryo switch, ultimately swapping babies with another family.

Experts warn IVF errors, though rare, highlight a lack of regulatory oversight, prompting calls for stricter safeguards in fertility clinics.
