Safe With FCNE: Our Management of Cryopreserved Eggs and Embryos

safety of cryopreserved eggs and embryos

Though the exact details remain unclear, the recent events highlighted in the news have certainly raised concerns regarding the management and safety of cryopreserved specimens. After cryopreservation, oocytes or embryos are stored in tanks which must be kept filled with liquid nitrogen in order to maintain proper storage temperature and conditions. All liquid nitrogen storage […]

Study Confirms Safety of Using Vitrification Method

cryopreservation

A European study of nearly 3000 patients confirmed the safety of freezing using the vitrification method and transferring cryopreserved embryos.┬áThe study of over 1000 live births from frozen embryo transfers and nearly 2000 live births from fresh embryo transfers revealed no differences in outcomes for the offspring. The study particularly focused on major congenital malformations […]

Laser Assisted Hatching of Vitrified Embryos

A human egg or oocyte is surrounded by an outer protective shell known as the zona pellucida. As an embryo develops from zygote (day 1) to blastocyst (day 5), the outer zona progressively thins (see photos of day 3 embryo with thicker zona and day 5 blastocyst with thin zona). This ultimately enables the embryo […]
