Egg donation and embryo donation, are they the same?

Embrión mosaico

Although the two terms are similar, egg donation and embryo donation are two completely different assisted reproduction treatments. Egg donation consists of carrying out the fertilization process with the eggs of an anonymous donor and the sperm of the couple.

On the contrary, embryo donation is when the transfer is performed using embryos that have been donated by other patients. These donated embryos are from patients who did not need to use them in their own treatment. This is because, in an in vitro fertilization (IVF) or egg donation cycle, several embryos are incubated simultaneously. Among those that reach the blastocyst stage, one of them is transferred to the patient and the remaining ones are vitrified for later use. In this case, if the patient achieves pregnancy and has more embryos, but does not want to undergo further treatments, she can donate them.


The main differences between egg donation and embryo donation are that, while in the first case it is necessary to fertilize the egg in the laboratory until the blastocyst is obtained to be transferred later, in embryo donation or embryo donation, a previously frozen embryo is transferred.

Thanks to oocyte donation treatment, women who cannot get pregnant with their own eggs can do so with donor eggs.OvobankID, in addition to having a large pool of donors, complies with rigorous donor selection protocols in order to obtain high success rates.



As advised by our specialists, oocyte donation should be the treatment you should seek if you are a woman with:

o Insufficient ovarian reserve or ovarian quality.

o Early menopause.

o Repeated miscarriages due to poor oocyte quality.

o Previous unsuccessful treatments due to poor oocyte quality.

o Genetic diseases.


OvobankID performs a selection of donors following a very rigorous protocol:

First of all, a donor is sought who is compatible with the blood group of the patient or the couple. Also, the donor is studied to have similar physical characteristics to the recipient. Thanks to the facial recognition app Ovomatch, it will be possible to search for the donor who is physically most similar to the recipient. If the patients wish, a Genetic Compatibility Test (GCT) can also be requested to reduce the risk of the baby developing genetic diseases.Tener entre 18 y 33 años de edad, aunque la ley establece un máximo de 35 años.

Secondly, a specialized team will check that the egg donor meets the following requirements:

o Psychological evaluation.

o No personal or family history of serious hereditary diseases.

o No history of gynecological pathology.

o That she is not a carrier of infectious diseases.

o Genetic studies to rule out more than 30 recessive diseases, including the most frequent in the population.

OvobankID has the largest pool of donors, thanks to its collaboration with centers around the world, which allows access to multiple donors of all breeds, nationalities, and phenotypes.
