Wanting to be a mother is an achievable and possible dream with the egg donation techniques that we carry out at the Cefer Reproduction Institute.
The progressive delay in the age to have children in our society reduces the chances of becoming pregnant. For this reason, techniques such as egg donation or more correctly called Donor Egg Reception, is an essential aid for many women with oocyte factor to fulfill their desire to be a mother.
Although it is commonly known as egg donation, the correct name for this technique is “reception of donated eggs” since the process carried out by the donor is also called egg donation. It is the solution for all those couples who present an oocyte factor.
To proceed with this technique, the woman’s uterus must be healthy.
The donor is required to perform a series of tests required by law.
Our donors are young voluntary university students who have to pass, in addition to the tests required by law, our own studies.
Once the tests have been passed, the donor must come every day so that our nurses can administer the medication correctly.
We use the most effective and safe medication: recombinant hormones.
Did you know that all our donors have Genetic studies among them? They are studied for the 33 most serious and frequent genetic diseases, because safety is not an option. It adds an important plus in safety to all the studies that we have been carrying out in CEFER fertility centers. Egg donation can also be made with fresh eggs, so you don’t have to worry about survival after vitrification (thawing).
But if you want maximum security, we can find your ideal donor because we will not only take into account your physical characteristics (breed, weight, eye and hair color, hair texture, etc.) but genetic compatibility in order to reduce risks for the most of 310 frequent and high-impact genetic diseases using the Compatibility (HERES Test)
If you are interested in knowing more about Compatibility, read below.
At the level of results, without a doubt, this technique is the one that offers the best results.
You administer the treatment with pills or patches. After 2 weeks we do an ultrasound check of the endometrium (internal part of the uterus) to verify that it is optimal. Then you have to continue after the transfer, until the pregnancy test
After the study and selection of healthy and fertile donors, only 20% are accepted and begin a stimulation treatment for which they come to the center to be administered the medication and carry out controls.
This phase is followed by the extraction of the ovules.
We isolate the healthy sperm from the rest of the semen. If you are undergoing IVF, the eggs are placed in the culture dish. With the ICSI technique, a healthy spermatozoon is directly introduced into each mature egg, avoiding non-viable embryos. In some cases we can recommend performing the IMSI in addition to the ICSI.
This technique supposes a selection of the spermatozoon to fertilize each ovule much more precise than ICSI, since a much more powerful microscope is used (16000 magnifications compared to 400 of a normal one), we can observe if there are vacuoles inside the nucleus of the spermatozoon, correlated with DNA abnormalities.
*IMSI is available for now at the cefer fertility center in Barcelona
After 16 to 20 hours of the introduction of the spermatozoon in the ovule, a study is made again under a microscope. If two circles (pronuclei) are seen, the ovum is fertilized! We already have an embryo. And we will inform you as soon as we know!
Every day the embryologists follow the evolution of the embryos one by one. This monitoring provides information of great value to select which are the most likely to be a mother to give you.
We have the new Timelaps embryo incubation system (Geri and EmbryoScope) that incorporates an image capture system. This makes it possible to follow the evolution of each embryo without removing it from the incubator, seeing its evolution in first person.
Among its advantages, it is worth noting that it provides much more of this valuable information that helps to detect morphological abnormalities in the embryo that are not visible with traditional methods, in addition to improving the selection of the best embryos with the greatest potential to leave you in a state.
it also allows the incubation of the embryo to be more stable, keeping the temperature, humidity and the environment without variations since they do not have to be taken out to observe them.
This makes it possible to increase the viability of the selected embryos, and, with it, their gestation, reducing the abortion rate by half compared to not making said sperm selection.
Embryo Transfer does not require sedation, as it is not annoying. It is performed eco-guided, that is, under ultrasound control, which allows us to ensure that the embryos are deposited correctly.

Recent scientific studies show that the risk of genetic disease is greater than previously thought, even in the absence of a family history.
The new genetic tests are a revolution in reproductive medicine since they allow the study of a large number of diseases at the same cost as until recently, for just one.
DNA analysis, offered by the I.R. CEFER, from a small blood sample, reduces to a minimum the risk of babies affected by up to 310 diseases of genetic origin.
Advantages of doing a Genetic test (Compatibility or Genetic)
It provides more information than current diagnostic methods. An example: the traditional study of Cystic Fibrosis (valued at €330) studies 34 mutations of the causative gene; with the compatibility test we studied 140 mutations (+400%).
Many more diseases studied at much lower cost than the traditional equivalent. With the Genetic we study 33 genetic diseases in the donor and with the Compatibility we study the DNA of the donor and the man for more than 310 diseases because you want a healthy family. The cost per disease studied does not exceed €3.
Among the diseases studied are those with the greatest impact such as Cystic Fibrosis, Fragile X Syndrome, Spinal Muscular Atrophy, Sickle Cell Anemia, Alpha and Beta Thalassemia, and Tay-Sachs Disease.
In this line, at the Cefer Reproduction Institute we will continue to incorporate the latest innovations to transfer these improvements to our patients. At Cefer, we advance for you.

If you want your donor to look like you and your partner, we now have Fotomatch facial recognition technology to objectively select the best donor for you. The CEFER Institute is the first center in Spain to apply this technology.
