The slow freezing approach worked well for embryos but not for eggs. The second technique to cryopreserve oocytes is vitrification, which was introduced around 2006 and is much more efficient than its predecessor.
When did egg vitrification start?
In 2003, Dr. Noyes and other doctors throughout the United States started their own clinical trials. They offered existing infertile I.V.F. patients a free cycle, freezing the eggs with both slow freezing and a new rapid-freezing method called vitrification.
When was oocyte cryopreservation invented?

Successful pregnancies from frozen oocytes were first achieved in the late 1980s, using slow-freeze and rapid-thaw cryopreservation techniques ( Chen, 1986 , 1988 ; Van Uem et al., 1987 ).
