How many eggs implanted ivf

Embryo transfers using fresh embryos had a 23 percent pregnancy rate, whereas frozen embryos had an 18 percent pregnancy rate. The study showed that frozen embryos could also be used for additional embryo transfers where fresh embryos could not.

If the chance for pregnancy is low, doctors may consider freezing additional embryos for a second attempt at embryo transfer at a later date. Individual success rates can vary and may depend upon the cause of infertility , ethnic backgrounds, and genetic disorders. The risks of embryo transfers themselves are very low. These risks are mostly related to increased hormonal stimulation, causing an increased risk such as a blood clot blocking a blood vessel.

The woman can also experience bleeding, changes in her vaginal discharge, infections, and complications of anesthesia if it is used. The risk of a miscarriage is about the same as in natural conception. The greatest risk of embryo transfer is the chance of multiple pregnancies. This occurs when multiple separate embryos attach to the uterus. This may increase the risk of stillbirth and children born with disabilities, and is more common in pregnancies due to IVF than natural conception.

What to know about embryo transfers Medically reviewed by Nancy Choi, M. What is an embryo transfer? Although multiples can be born healthy, they are more likely to be born prematurely than singletons.

Lower birth weights are also more common, the risk of which increases as the number of multiples increases. Additionally, women carrying more than one baby at a time are more likely to develop complications during pregnancy. Some of the most common complications include high blood pressure, preeclampsia, and gestational diabetes. One reason some patients choose to have multiple eggs transferred instead of one is to try to increase their chance of successfully conceiving during a single round of IVF.

For these patients, multiple transfer may provide the most successful results. Single embryo transfer can be successful for women over their mid-thirties.

One key factor in success rates is egg quality. As women age, the quality of their eggs decreases. Harvesting eggs before a woman is 35 and freezing them for future use can preserve egg quality. Women older than 35 who use eggs that were harvested when they were younger often experience the same success rate with single embryo transfer as women who are under This means older women can have a single embryo transferred and save the rest of their embryos for when they are ready to have another child.

This allows them to transfer a single embryo without increasing their risk of a multiple birth. Multiple embryo transfer is most beneficial to women who are over 35 and did not have their eggs frozen when they were younger. In such cases, multiple embryo transfer can be more successful than single embryo transfer. Patient Resource Center.

Patient Portal. Request a Consult. Number of eggs retrieved and IVF success rates according to female age. To a great extent, the more eggs we have to work with, the greater the chance that IVF will be successful.

There are several issues involved with this: More eggs will give us more fertilized eggs — which results in more likelihood of having good quality Women that respond well to the stimulation drugs sometimes also have better egg quality — and therefore could be more likely to have some high quality embryos.
