If your fertility doctor’s recommendation for you is using donor eggs for a successful conception, then it is a good moment for you to learn more about donor eggs, who can be a donor and what the requirements to donate eggs are.
First of all, you need to know that to be an egg donor a woman has to undergo strict selection process and numerous medical, psychological and genetic tests. The participation of donors is voluntary and they all are evaluated very carefully to avoid unwanted consequences. EggDonationFriends have checked what the process of being an egg donor looks like at Instituto Bernabeu, an IVF clinic in Spain,. Here is what we have found out.
At no extra cost to the recipient patient, Instituto Bernabeu analyses 600 most common genetic disorders. Such disorders can cause serious and incurable conditions that can even lead to premature death of an unborn child. Using donor eggs tested by Instituto Bernabeu can give you peace of mind that a situation like this does not happen.
The egg donor selection at Instituto Bernabeu is a strict process and the responsibility is taken on by the entire medical team and is given absolute priority. The most demanding criteria are taken into account and evaluation does not centre exclusively on the recipient partner’s physical characteristics, it also includes an interdisciplinary study. Here are the details.
Requirements to donate eggs
To apply to be an egg donor does not mean that the woman gets easily accepted into the program. The donor selection process is incredibly thorough and even 5 out of 10 candidates are excluded. 26% of candidates are excluded after having undergone a personal and psychological evaluation carried out by a fertility expert; 11.6% are eliminated from the process following genetic and chromosomal screening; the medical examination rules out further 8% of women; and 0.5% do not enter the egg donation programme after having taken and failed the infectious diseases test. This means that Instituto Bernabeu is a fertility clinic that carries out the largest number of checks.
After women apply to be an egg donor at Instituto Bernabeu they have to undergo a number of tests:
- Psychological Evaluation that is conducted by a clinical psychologist. The assessment includes an interview with the candidate and using the clinic’s own Psychological Assessment Questionnaire EMAE to find out more about the candidate’s personality.
- Medical history background check – the clinic’s gynaecologist evaluates the candidate’s and her family’s medical history. The candidate is also examined gynecologically to exclude any pathology.
- Chromosomal and genetic screening to eliminate the possible presence of the most common hereditary diseases in your geographical area that could be transmitted to your children: karyotype, screening for cystic fibrosis, Fragile X syndrome, genetic study of Thalassemias. Also, it is worth mentioning that the DNA acquired for these genetic tests is stored in the clinic’s Biobank in case it might be needed in the future.
- General health analysis: blood type and Rh factor, syphilis serology, Hepatitis B and Hepatitis C serology, HIV serology and clotting factors.
- Screening for Cytomegalovirus (CMV).
In the summer of 2017, a free Genetic Compatibility Test (GCT) was also added to this extensive list. GCT results identify more than 600 hereditary diseases through analysing only a blood sample. All this to ensure you can have a healthy offspring using oocytes from the clinic’s egg bank.
You need to remember that big majority of people are healthy carriers of some recessive disorder. Let’s say the egg donor and your male partner are carriers of the same disorder, it may be that a baby conceived with your biological material may inherit the specific disorder. The genetics laboratory at Instituto Bernabeu carries out this test on both semen and ova to identify those gene mutations that cause recessive diseases. This information is crucial to help reduce the risk of children being born with a hereditary condition.
Instituto Bernabeu Egg Donation Programme allows you to select a healthy egg donor and also a donor that suits your other requirements like ethnicity or physical characteristics (eye/hair colour). The clinic’s statistics on success rates are as follows:
- 5% – positive pregnancy rate (including frozen embryo transfers),
- 94% – fresh eggs donation,
- 89% – egg donor cycle with frozen embryos,
- 99% – 5-6 day transfer (blastocyst stage),
- 75% – day 5 blastocyst (the embryos reach blastocyst stage).
The clinic has treated over 46,400 patients from over 64 countries. If you would like to be one of them, contact the Bernabeu clinic for a free online consultation.
