Afterward, the embryologist carefully examines the catheter under a microscope to ensure the embryo is no longer inside the device. About 10 days after the embryo transfer, a blood pregnancy test can confirm if the procedure was successful.
Freezing embryos involves costs to cover the initial hormone treatments; egg harvesting; fertility; and embryo culture, freezing, storage and implantation. Some medical insurance plans cover assisted reproduction techniques, including the procedures associated with embryo freezing. Health Home Treatments, Tests and Therapies.
What You Need to Know The procedure involves removing eggs from the ovaries, fertilizing them to create embryos, letting them grow for several days and then freezing them. Why would I choose to have embryos frozen? How do I prepare for having embryos frozen? Freezing Embryos Embryo Cryopreservation : What Happens When the fertility specialist determines you are ready, the doctor will harvest eggs in an outpatient procedure performed under light sedation called an egg retrieval.
How likely is embryo freezing to result in a pregnancy? What are the risks of freezing embryos? Where are frozen embryos stored? Learn more about our lab. Have you ever worried about your chances of becoming pregnant?

Talk to me, Doctor!! You Might Also Enjoy However, the medical community still requires more long-term follow-up studies. Any complications or side effects of embryo freezing usually occur when the doctor is extracting the eggs. At this temperature, almost no biological processes, such as aging, can occur. There are examples of successful pregnancies resulting from eggs that people have stored for up to 10 years. No long-term research into embryo freezing exists because doctors have only been carrying out the procedure since Some countries regulate the length of time that a person can store their embryos.
Freezing and storage are expensive, and each clinic has its own rules about what happens if a person can no longer use their embryos or keep them frozen. A study published in the International Journal of Reproductive Biomedicine looked at the results of over 1, instances of embryo transfer involving either fresh or frozen embryos.
The researchers found no statistical difference between the types of embryos, in terms of pregnancy rates or fetal health. The authors pointed out that people could use frozen, but not fresh, embryos for additional transfers in the future.
Results of research published in indicate that frozen embryo transfer might lead to a higher rate of pregnancy and better outcomes for both the woman and baby. People who are approaching an advanced reproductive age and who are not yet ready to have children may also benefit from freezing embryos for later use. People may benefit from this process if they have a higher risk of ovarian stimulation syndrome.
This is a rare and potentially dangerous condition that can arise when a person is receiving stimulating hormones to increase egg production.
To reduce the risk of this condition, a doctor may recommend freezing the embryo and transferring it when the ovaries are no longer stimulated. A doctor can also use a freeze-all cycle to test an embryo for a genetic disorder.
This involves removing a few strands of DNA and testing the chromosomes. Embryos with a standard set of chromosomes are more likely to transfer successfully. Prescreening can ensure that future offspring have a lower chance of developing genetic diseases. Possible risks include a slightly higher chance of genetic abnormalities in the child.
It is important to note that, because this is a new procedure, the long-term health effects are not yet clear. In addition, fertility treatment can lead to ovarian hyperstimulation syndrome. In fewer than 2 percent of cases, symptoms are severe, but they are unlikely to be life-threatening. Finally, treatment can be costly. However, it offers a wider range of options for people who wish or need to delay pregnancy, or who may otherwise be unable to conceive.
Most importantly, the only way to get the cooling rate required is by having the cells in direct contact with liquid nitrogen and liquid nitrogen can be a vehicle for disease transmission. Vitrification is used quite a bit in Japan and by a few places in the U. In contrast, there are many traditional cryoprotectant solutions that you can buy from vendors that are FDA-cleared.
So although vitrification is a bit problematic and hasn't yet provided superior outcomes, it is much superior on the time frame. It also doesn't require expensive equipment that can cool chambers at a third of a degree a minute.
It has some theoretical advantages but it's not out of the woods yet. SA: How long does the traditional cryopreservation process take? The standard method takes about two hours.
Negative degrees C. It is certainly close enough to stop biological activity and allow babies being born from frozen embryos that have been frozen for up to 14 years. Fourteen years is the longest--that I am aware of--for an embryo being frozen that resulted in a live birth.
SA: Are there any limits on how long embryos can be stored? It is theoretically much longer than [14 years]. It should be a century or two, even, though it's not unreasonable to think there would be some degradation over time.
We've learned a lot about cryopreservation since the first embryo freezing around 20 years ago. The embryos that were frozen back then could have all been used up--people don't usually wait 14 years to have kids. The nature of reproduction and building families does not really foster an environment that would allow you to wait 50 years before you thaw your embryos out. Unless your daughter wanted to carry her sibling, for example, which in theory is possible: a person born from IVF may still have sibling embryos frozen and when they reach 30 and are infertile could technically thaw out the embryos that were created at the same time they were created, gestate them and deliver their sibling.
That hasn't happened yet but it could be possible. SA: How are the embryos treated prior to use or implantation? It's basically the reverse process.
