Egg donation is one of the treatments with the highest success rates. Offers women who cannot have children the possibility of being mothers using eggs from an anonymous donor.
Ovoclinic is the ideal place to carry out your ovodonation treatment as we are specialists in this type of treatment. Ovoclinic is part of Ovobank, the first egg bank in Europe, with the guarantees that it offers:
- Extensive experience.
- More than 300 centres nationally and internationally have trusted the quality of our eggs and continue to do so.
- High rates of gestation.
- Strict criteria for selecting donors, accepting only 30% of potential donors based on our protocols.
- Ovobank has large pool of donors, which makes it easy to find the ideal donor for each patient, being able to choose from a wide variety of phenotypes.
- A DNA sample of all donors is kept in case it is necessary to use it in the future.
- Be between 18 and 33 years old.
- Psychological assessment by a mental health expert
- No personal or family history of serious hereditary diseases.
- No history of gynaecological pathology.
- Not a carrier of sexually transmitted diseases.
- Genetic testing ruling out more than 30 recessive diseases, including the most frequent in the population
Donor selection is based on two main criteria:
The donor must have a compatible blood group with the patient or her partner and must have similar physical characteristics to the recipient.
At Ovoclinic we use Ovomatch, a facial recognition technology that compares the reference points of the face so that the donor not only has similar general physical characteristics (hair colour, eye colour, etc.) but also similar facial features.
In addition, if you wish, a genetic compatibility test can be performed to reduce the risk of the baby developing genetic diseases, being able to study more than 300 pathologies. For this study the male partner or the male donor must carry out this same genetic test.
The patient will follow a very simple treatment to prepare the endometrium to receive the embryo. An oral or patch medication is normally used to thicken the endometrium. After about 10-15 days, if the endometrium is ready, fertilization of the eggs and transfer can be scheduled. Before this, the patient must add progesterone to the treatment to imitate what happens in a natural cycle.
In egg donation with fresh eggs, the donor and recipient must be available to start their treatment at the same time. In the case of vitrified eggs, synchronization is not necessary, therefore waiting times are reduced.
Once the eggs have been collected, they are fertilized with semen from the recipient’s partner or from a sperm donor, as appropriate, and embryos are cultured in special incubators that mimic the humidity and CO2 concentration conditions of the mother’s uterus. In FIV Marbella all our embryos are cultivated for five or six days, until they reach the blastocyst stage. This allows us to select the most suitable embryos to achieve pregnancy.
After embryo culture is complete, specialists will select the highest quality embryo for transfer to the recipient’s uterus. The remaining embryos can be frozen for subsequent attempts or for a second pregnancy.
Who is it for?
- Women with insufficient ovarian reserve or quality.
- Premature menopause
- Repeated spontaneous miscarriages associated with poor egg quality.
- Previous failed treatments in which an egg cause is suspected.
- Genetic diseases in women that cannot be ruled out using PGD.
- Will I be able to know who the donor is? Will the donor know who my child is?
Law 14/2006 describes that egg donation must be anonymous, so the identity of the donor is completely confidential, in the same way that the donor will not have the right to know the identity of the born child. There is also no possibility of the born child finding out who the donor was years later.
Only exceptionally, in circumstances that pose a certain danger to the life or health of the child, the identity of the donors may be revealed, provided that such disclosure is essential.
The only information we can give about the donor is important information regarding pregnancy, such as age.
- What is epigenetics? Will my egg donor born child inherit anything from me?
There are many studies currently on epigenetics. According to these, although the genetic information of the embryo would come from the donor, during pregnancy, the mother could modulate that genetic information. These processes occur through the exchange that takes place while the baby is in the womb and consist of a series of biochemical signals that can activate or inhibit certain genes of the embryo.
- What is genetic grief?
For many couples who have to resort to donated gametes (either sperm or egg), it is difficult to accept that their child will not have their genetic heritage. This completely normal emotional reaction is what is called genetic grief.
Talking openly about the doubts with professionals, maintaining communication with your partner and resorting, if necessary, to professional support such as our psychologist will help to accept these feelings, get excited again, and start again on the journey to parenthood.
- Is there a waiting list for egg donation?
At Ovoclinic we are part of Ovobank, with multiple centres nationwide and a very high number of donors, so we do not have waiting lists to find the ideal donor for each patient.
voclinic opened in January 2019, so there are no reliable data for statistics yet. the success rates shown correspond to those of our headquarters in Marbella. The percentages presented in this section have been divided as follows:
Beta-hCG positive: Extracted from the level of beta-hCG hormone (β-hcg) in blood 10 to 12 days after embryo transfer. This is the hormone produced by the body after the embryo implants in the uterus, making it an excellent indicator of the early existence of pregnancy.
Clinical Pregnancy: Around the fifth week of pregnancy the gestational sac appears, a small sac of about two millimetres that surrounds the embryo. Its presence on the first ultrasound is a good sign that the embryo has successfully implanted in the endometrium.
SEF: Spanish Fertility Society is a scientific non-profit organization whose purpose is to promote studies related to fertility and assisted human reproduction. This organization publishes an annual report with different success rates in assisted reproduction treatments based on the results obtained by Spanish fertility clinics. The data shown here are from latest report published by the SEF.
