As freezing technology evolves, so too does our method of thawing eggs and embryos
News of a baby born from an embryo frozen 24 years ago circulated through the headlines recently. Having once transferred an embryo frozen 19 years prior, Dr. Debroah Wachs was contacted by The Atlantic to comment on the current state of embryo freezing techniques and technology.
Freezing processes have changed vastly over the last quarter-century. This means newer embryologists may only be familiar with vitrification, a revolutionary rapid freezing and thawing technique, and not the slow-freeze methods used in years past, she explained. This in turn affects how many medical professionals possess the knowledge to thaw eggs and embryos frozen many years ago using older technology.
