Ovodonation treatment is aimed at women who do not produce quality eggs and cannot achieve pregnancy on their own. It consists of an IVF treatment in which the fertilized egg comes from a donor. This technique allows patients with fertility problems to develop their own pregnancy.
- Be between 18 and 33 years old.
- Not having a personal or family history of serious hereditary diseases.
- Having no history of gynaecological pathology.
- Not be a carrier of sexually transmitted diseases.
Donor selection is based on two main criteria:
Phenotypic characteristics: Hair colour, eyes, race, blood group … In this way we mimic the conditions in which a spontaneous pregnancy would occur.
Genetic compatibility: The donor cannot carry genetic diseases that may manifest in the baby.
In fresh egg transfers, the donor and recipient treatment cycles must be performed in a synchronized manner, although both will never be known.
In the case of the donor, an ovarian stimulation treatment will be carried out that will end with the follicular puncture and the extraction of several ovules. For its part, the patient will undergo an endometrial preparation process to facilitate implantation of the embryos in the uterus.
In the case of a transfer with frozen oocytes it will not be necessary to coordinate the medication cycles, so the patient can choose when to start her treatment.
Once the ovules have been removed, they are fertilized with semen from the recipient or donor couple, as appropriate, and grown as embryos 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 phase. This allows us to select the most suitable embryos to achieve pregnancy.
From among the embryos selected after incubation, one of them will be transferred to the patient directly inside her uterus. The rest will be vitrified for use in subsequent transfers if necessary.
Who is it for?
- Low ovarian reserve or insufficient ovarian quality.
- Early menopause.
- Repetition abortions.
- Exhausted previous treatments.
- Absence of ovulation.
- Will I be able to know who the donor is? Will the donor know who my child is?
Law 14/2006 states 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 that the born child can know who the donor was years later.
Only exceptionally, in circumstances that present a certain danger to the life or health of the child, can the identity of the donors be revealed, provided that such disclosure is indispensable.
The only information we can give from the donor is important data regarding pregnancy, such as age.
- What is epigenetics? Will my son born through egg donation 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 by the exchange that occurs 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 semen or ovules), it is difficult to accept that their child will not have their genetic legacy. This completely normal emotional reaction is what is called genetic grief.
Talking openly about any doubts with the professionals, maintaining communication with the couple and resorting to, if necessary, professional support such as our psychologist will help to accept these feelings, get excited about parenthood again and resume the path to becoming parents.
- Is there a waiting list for egg donation?
In FIV Marbella we are part of Ovobank, with multiple centers nationwide and a very high number of donors, so we do not have waiting lists to find the ideal donor for each patient.
he success rates shown correspond to those of our headquarters in Marbella. The percentages presented in this section have been divided as follows:
eta-hCG positive: hormone produced by the body once the embryo is implanted in the uterus. Calculated after 10/12 days after embryo transfer.
Clinical Pregnancy: Calculated in the 5 week gestation by means of ultrasound. Its presence is a sign of implantation of the embryo in the endometrium.
SEF (Spanish Fertility Society). The rates shown here correspond to the last report published by the agency in 2016.
