Is freezing embryos more successful than freezing eggs?
Higher Success Rate Thanks to modern science, about 90% of frozen eggs survive; meanwhile, about 95% of embryos survive. With frozen embryos, you have more opportunities to transfer fertilized eggs, which means you have a higher chance of pregnancy.
What is the success rate of IVF with frozen embryos?
LIVE BIRTH RATES Of 2,114 chromosomally normal frozen embryo transfers, among women under 35 years old, 68.8% resulted in a live birth. Of 1,760 chromosomally normal frozen embryo transfers, among women 35 – 37 years old, 68.9% resulted in a live birth.
Are frozen embryo transfers more successful?
Many fertility specialists and treatment providers indicate that frozen embryo transfers provide a higher pregnancy success rate than using fresh embryos during assisted reproductive technology.
Does freezing damage embryos?
Freezing can damage embryos. Thawing them later can also damage them. If multiple embryos are frozen, some or all may not survive the process. Your healthcare provider will talk to you about whether your embryos are suitable for freezing, thawing and implantation.
What percentage of frozen embryos survive the thaw?
The chance of pregnancy from embryo transfer is largely dependent on the age of the woman when embryos are created. Procedures using eggs harvested from people age 35 or younger have the highest chances in resulting in a pregnancy. Over 95% of frozen embryos survive the thawing process.
Can a frozen embryo split into twins?
Can an embryo split into twins? The short answer is yes, but the chances are quite small. Just like with any pregnancy, a twin pregnancy can still happen. In IVF, the chance of this outcome is approximately one out of 100 transfers.
Are frozen embryos slower to implant?
Unlike fresh embryos, which usually implant within one or two days after a blastocyst transfer, frozen embryos take a little longer to implant. Usually, they implant within five days. This is referred to as late or delayed implantation.
What are the odds of a frozen embryo transfer?
Frozen Embryo Transfer Success Rates For patients 35 or younger, there is a 60% pregnancy rate per embryo transfer, whereas women over the age of 40 have a 20% pregnancy rate per embryo transfer.
How often do embryos not survive thawing?
And yes, there is a chance an embryo does not survive the thawing process. Though rare, others may get damaged due to human error. Overall, statistics show that 9 out of 10 embryos thawed survive. The increased survival rate is down to improved freezing techniques called vitrification.
How can I improve my successful frozen embryo transfer?

Do most embryos survive thaw?
The survival rate was 69% for thawed zygotes, 85% for D3 embryos, and 88% for blastocysts [Table 1]. The implantation rate per number thawed was 10% for zygotes, 12% for D3 embryos, and 14% for blastocysts.
Why are some embryos not suitable for freezing?
Why are only some embryos frozen? Not all embryos develop well in the laboratory. Any embryos which are not well developed (frozen or not frozen) have little chance of resulting in a pregnancy so freezing all embryos can give couples false expectations and increased costs.
