In early 2020, U.S. mother Tina Gibson gave birth to a healthy baby girl from an embryo frozen since 1992—27 years prior. This achievement underscores that frozen embryos truly have no expiration date and surpasses her own 2017 record with another child from a 24-year-old embryo.
As detailed in a December 3, 2020, New York Times article, Tina Gibson received an embryo implant in February from a Midwest clinic where it had been frozen by a couple in 1992—Tina herself was just a baby at the time. Nine months later, she delivered Molly, a thriving baby girl.
This birth shattered Gibson's previous milestone: In 2017, she welcomed Emma, Molly's older sister, from a 24-year-old embryo from the same donor couple. Martha Earl, director of the Preston Medical Library at the University of Tennessee, verified this as the longest-recorded interval, after reviewing extensive scientific literature with no precedents exceeding two decades.
"If an embryo survives thawing well, it should have as much chance as a fresh one," explains Dr. Jeffrey Keenan, director of the National Embryo Donation Center.
Concerns about embryos being "too old" are unfounded, with no apparent time limit, as this case demonstrates. Dr. Mindy S. Christianson, medical director at Johns Hopkins Fertility Center, calls it encouraging news for fertility specialists, offering reassurance to patients pursuing embryo donation.
Dr. Sigal Klipstein, director of Chicago's egg donation program, emphasizes that embryo quality at freezing is key—not the storage duration. High-quality embryos maintain their viability over time.
