A pair of twins, Lydia and Timothy Richey, were born in Oregon, USA, and their embryos have been frozen for 30 years. This astonishing fact makes them the known longest-frozen twins in the world. The twins’ parents, Philip and Rachel, realized their family dream by implanting these frozen embryos. This event has once again sparked public interest and reflection on the technology of frozen embryos.

Since the concept of frozen embryos was first proposed in the 1980s, it has undergone continuous development. Initially, fertility experts attempted to freeze embryos under laboratory conditions. Although the technology at that time was not mature, with scientific advancements, frozen embryos gradually became a choice for many couples hoping to conceive but facing fertility challenges.

For couples with fertility issues or those choosing to delay childbirth, IVF offers a flexible family planning schedule. Although the success rate of IVF does not always yield results on the first attempt, utilizing frozen embryos allows these embryos to be used in future cycles, significantly increasing the success chances of each cycle. Meanwhile, frozen embryos provide convenience for couples wishing to postpone pregnancy for career or health reasons. Currently, more than 500,000 frozen embryos are stored in clinics across the USA, ready to help more families achieve their reproductive wishes.

Research shows that the viability of frozen embryos is comparable to that of fresh embryos and can be safely used months or years later. No genetic abnormalities have been found to result from freezing. Statistics indicate that women or couples typically use these embryos within 5 to 10 years after the initial freezing.

Dr. Nathan Zhang from IVF USA emphasizes that frozen embryos are an indispensable part of the IVF cycle, with nearly all IVF cycles involving embryo freezing and genetic screening. If the first transfer does not succeed, frozen embryos can be used in subsequent cycles, greatly increasing the likelihood of success. It is important to note that several factors influence the viability of frozen embryos; thus, it is recommended that women under 35 provide more quality eggs to create healthier embryos.

Currently, IVF USA offers services such as egg freezing and IVF in the USA, with operations expanded to IVF and egg freezing in Japan, Thailand, and regions like Mexico, Taiwan, and Hong Kong, closely collaborating with IVF doctors worldwide.
