frozen embryos
Suspended early life
Frozen embryos are human embryos preserved through cryopreservation, typically created during in vitro fertilization when more embryos are produced than immediately implanted.
They can remain viable for years or decades in liquid nitrogen.
Frozen embryos occupy contested legal and ethical territory—variously treated as property, potential persons, or something in between: The divorce settlement included a dispute over their frozen embryos.
