Earlier this year, a mother in Tennessee gave birth to a healthy baby born from an embryo frozen 24 years ago. This remarkable case appears to represent the longest time frame for a frozen embryo to result in a successful live birth. The baby girl, Emma, was conceived through a process called embryo adoption. The couple […]
Do Women Know They Can Freeze Their Eggs?
A recent study in Human Reproduction researched the awareness of egg freezing among women. Do women know they can freeze their eggs? The study found that many women who might desire children in the future know little or nothing about the option to freeze their eggs. This study interviewed 500 Canadian women (ages 18 to 38) […]
A European study of nearly 3000 patients confirmed the safety of freezing using the vitrification method and transferring cryopreserved embryos. The 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 […]
Cryopreservation: What is it?
Cryopreservation (freezing) of embryos has been associated with IVF since its inception in the 1908’s. The use of Frozen Embryo Transfer (FET) has resulted greater than 150,000 health births worldwide. The availability of freezing viable human embryos is a necessary and desirable process. Cryopreservation indirectly allows for the control of how many embryos can be […]
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 […]
Reproductive Freedom: Why Freeze Your Eggs?
When pregnancy is desired, success is expected immediately. Yet, the ability to have a baby is age related and the ‘Biologic Clock’ may run out before the right partner appears. Egg freezing offers young women the potential to preserve their fertility regardless of the age they decide to try and become pregnant. Unfortunately, by the […]
