The birth of a little girl named Molly in Tennessee, USA, set a new world record for the longest time a frozen embryo has successfully developed and been born—27 years.

 

 "Frozen" for 27 Years: The Astonishing Potential of Frozen Embryos

 

Molly's mother, Tzina, aged 29, and her 36-year-old husband, Benjamin, decided to welcome a new life through embryo donation after years of unsuccessful natural pregnancy preparation.

 

 Love Beyond Genetics: Tzina and Benjamin chose an embryo that had been frozen since 1992 through the National Embryo Donation Center. This embryo first brought them their elder daughter, Emma, and a few years later, welcomed their younger daughter, Molly. Although the sisters do not have a biological mother and father, they share the nurturing love of the same gestational mother (Tzina). Biologically speaking, Tzina is only two years older than Molly's embryo, which is astounding.

 Breakthrough in Freezing Duration: The successful births of Molly and Emma strongly demonstrate the stability of embryo freezing technology. Scientists speculate that, under correct preservation conditions, the cryopreservation period of embryos can theoretically be extended indefinitely, and their future developmental potential is not affected by the storage time.

 

 IVF-PGT: The Key to Ensuring Embryo Quality

 

Molly's miraculous success would not have been possible without advanced assisted reproductive technology.

 

 Advantage of Blastocyst Culture: In the US, fertility centers typically culture embryos to the blastocyst stage (Day 5) before freezing or transfer. Blastocysts are more mature, and the accuracy of genetic screening is higher.

 PGT Genetic Screening: Through IVF-PGT technology, doctors can perform comprehensive chromosomal screening on embryos, ruling out potential genetic diseases or chromosomal abnormalities, ensuring that the transferred embryos are healthier. This is crucial for increasing the pregnancy success rate and reducing the risk of miscarriage.

 

The story of Molly and Emma is not just a scientific triumph but a symbol of hope. It tells every family desiring a child that modern medicine has made pregnancy preparation plans more flexible and controllable. Whether facing advanced maternal age pregnancy preparation, infertility, or needing reproductive planning like US and Mexico egg freezing, advanced technology can offer solutions.
