A baby born in Ohio in 2022, from an embryo frozen in 1992, was recognized by Guinness World Records as the longest-frozen human embryo to result in a live birth — nearly 30 years and 7 months of cryopreservation. This underscores that viable human embryos can remain implantable after decades stored in liquid nitrogen.
The question, scope, and sources behind this Registry record.
A baby born in Ohio in 2022, from an embryo frozen in 1992, was recognized by Guinness World Records as the longest-frozen human embryo to result in a live birth — nearly 30 years and 7 months of cryopreservation. This underscores that viable human embryos can remain implantable after decades stored in liquid nitrogen.
The longest documented interval between cryopreservation of a human embryo and its successful transfer resulting in a live birth, as verified by fertility clinic and Guinness World Records documentation.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
