Cryopreservation has been an ongoing area of research in the United States since the 1930s, but only since the 1980s have scientists been able to freeze oocytes (human eggs) and then later use them to successfully birth a human baby. Since 1983, the technology for oocyte cryopreservation has advanced vastly, and has become a more widespread medical procedure. Different techniques have emerged, allowing for a higher likelihood that the eggs will survive freezing, and creating a more stable environment for the eggs until they need to be used again.

Today, Dr. Jonathan Karp and student producer Kaya Basatemur discuss what cryopreservation is, how it's done, why people may choose to do this, and what they do with the eggs after they are frozen. To learn more about this growing industry, make sure to tune in to this week's episode of Health 411!
