At the world’s first private frozen egg bank, LA Frozen Egg Bank rapidly freezes healthy oocytes and
keeps them at extremely low temperatures. When a client wants to become pregnant, it unfreezes
her oocyte for pregnancy. Unlike sperm banks which provide general services, egg banks require
much more sophisticated technology.
After 20-years of effort to create stable ‘human egg freezing technology,’ CHA Medical Group has
finally developed the world’s first ‘oocyte cryopreservation by vitrification’ in 1998. In 2005, CHA
Medical Group developed ‘oocyte cryopreservation using slush nitrogen’ which improved the
survival rate to 90%. Due to its advanced medical technologies, CHA group has been globally
recognized for its technical expertise and efficiency.
CHA Medical Group, recognized as a world class authority in global medical
circles with its state-of-the-art technology for infertility treatment,
opened Cha-Columbia Fertility Center in association with Columbia
University’s Department of Obstetrics and Gynecology in May 1999.
This remarkable achievement was realized thanks to CHA Medical Group’s
research infrastructure, advanced research, and outstanding technology.
It remains a case example of successfully exporting Korean medical
technology to the U.S., a nation at the forefront of advanced medicine.
Chairman Kwang-yul Cha served as an exchange professor for Columbia
University’s Department of Obstetrics and Gynecology.
