Η Ευγονία διαθέτει ένα επιτυχημένο και εξειδικευμένο πρόγραμμα δωρεάς ωαρίων, βασισμένο σε αυστηρά πρότυπα ηθικής και δεοντολογίας. Το πρόγραμμα μας εστιάζεται στην ασθενή, αποφεύγοντας το προφίλ προγραμμάτων δωρεάς μαζικής κλίμακας. Αυτό αντανακλάται και στα κορυφαία ποσοστά επιτυχίας της Μονάδας.
Ποιές γυναίκες χρειάζονται δωρεά ωαρίων
Αξιολόγηση και εξετάσεις της δότριας
Είναι γνωστό ότι ορισμένες γυναίκες δεν έχουν την δυνατότητα να παραγάγουν δικά τους ωάρια. Οι γυναίκες αυτές δεν έχουν άλλον τρόπο για να τεκνοποιήσουν, παρά μόνον την δωρεά ωαρίου. Αυτό σημαίνει ότι πρέπει να υποβληθούν σε εξωσωματική γονιμοποίηση, κατά την οποία θα χρησιμοποιηθεί το σπέρμα του συζύγου τους, με ωάρια κάποιας άλλης γυναίκας. Η δωρεά ωαρίων αφορά την διάθεση όλων των ληφθέντων ωαρίων από ανώνυμη δότρια για χρήση από μία ή περισσότερες ανώνυμες λήπτριες.
Στην κατηγορία αυτή βρίσκονται:
Πραγματοποιούμε ενδελεχή αξιολόγηση όλων των υποψήφιων δωρητριών, και μόνο αυτές που είναι ιατρικά και ψυχολογικά υγιείς γίνονται δεκτές στο πρόγραμμα. Επίσης, καταβάλλουμε κάθε προσπάθεια να αντιστοιχίσουμε τα χαρακτηριστικά της δωρήτριας με τα δικά σας στο μεγαλύτερο δυνατό βαθμό.
Συγκεκριμένα, στην Ευγονία οι δωρήτριες αξιολογούνται με βάση το προσωπικό και το ιατρικό τους ιστορικό από ομάδα ειδικών.
Τέλος, σημαντική παράμετρος στα προγράμματα δωρεών είναι η πλήρης ενημέρωση των υποψήφιων σχετικά με την διαδικασία της εξωσωματικής γονιμοποίησης, τους πιθανούς κινδύνους και την νομοθεσία.
1. Αξιολόγηση, ενημέρωση και συμβουλευτική
Στην 1η συνάντηση που θα έχετε μαζί μας, θα συμπληρώσουμε ένα λεπτομερές ιστορικό. Στη συνέχεια θα συζητήσετε με τον Διευθυντή της μονάδας για την προοπτική της δωρεάς, την κατάλληλη θεραπευτική προσέγγιση και το πρωτόκολλο φαρμακευτικής προετοιμασίας αφού γίνει πλήρης κλινική αξιολόγηση.
θα ενημερωθείτε πλήρως για το νομοθετικό πλαίσιο, την προετοιμασία και τις εξετάσεις της δωρήτριας, θα πάρετε πληροφορίες και οδηγίες για την δική σας αγωγή αλλά και συνολικά για την διαδικασία από την υπεύθυνη του προγράμματος δωρεών.
2. Κύκλος προετοιμασίας
Για να μεγιστοποιήσουμε την πιθανότητα επιτυχίας θα υποβληθείτε σε συγκεκριμένες εξετάσεις που θα σας προτείνουμε ανάλογα με το ιστορικό σας.
Αυτές μπορεί να περιλαμβάνουν υστεροσκόπηση, προγεννητικό έλεγχο, εξετάσεις του συζύγου.
Επιπλέον, αν το επιθυμείτε μπορείτε να ζητήσετε ραντεβού με την ψυχολόγο μας. Στόχος μας είναι να βοηθήσουμε το ζευγάρι να εξετάσει και να λάβει υπόψη του όλες τις πιθανές επιπτώσεις που μπορεί να έχει η προτεινόμενη θεραπεία, στους ίδιους, στην οικογένειά και στο παιδί που θα γεννηθεί ως αποτέλεσμα της θεραπείας αυτής.
3. Κύκλος θεραπείας
Είναι σημαντικό για την λήπτρια να έχει προετοιμαστεί με την κατάλληλη θεραπεία ώστε να συγχρονιστεί το ενδομήτριο της με τα γονιμοποιημένα ωάρια. Ο κύκλος θεραπείας για τον συγχρονισμό της προσπάθειας δημιουργεί το κατάλληλο περιβάλλον για την υποδοχή των εμβρύων. Ο κύκλος με ορμονική θεραπεία υποκατάστασης αποτελεί ιδανική λύση . Οι θεραπείες ξεκινούν βάσει περιόδου και περιλαμβάνουν χάπια και ενέσεις.
4. Το εργαστηριακό στάδιο
Το εργαστηριακό στάδιο αφορά τη γονιμοποίηση των ωαρίων με το σπέρμα του συντρόφου και την καλλιέργεια των εμβρύων στο εργαστήριο για 2-5 ημέρες.
Η όλη διαδικασία ολοκληρώνεται με τη μεταφορά των εμβρύων στην κοιλότητα της μήτρας της λήπτριας. Υπεράριθμα έμβρυα καταψύχονται και φυλάσσονται στην Τράπεζα Κρυοσυντήρησης της Ευγονίας για μελλοντική χρήση.
Εάν ενδιαφέρεστε να γίνετε δότρια ωαρίων και είστε κάτω των 35 ετών (απαραίτητη προϋπόθεση σύμφωνα με την νομοθεσία), μπορείτε να επικοινωνήσετε μαζί μας.
In most cases, severe male-factor infertility can be resolved through Intracytoplasmic Sperm Injection (ICSI).
However, in rare cases, sperm may be completely absent from semen (non-obstructive azoospermia). In such instances, the couple can only achieve conception by using donor sperm.
Donor sperm is obtained from specialized sperm donor banks. The minimum standards include the use of cryopreserved semen sample from a donor, who has been thoroughly tested for specific hereditary and acquired diseases, as required by law and international ethical standards. Donor selection is typically based on external characteristics such as hair color, eye color, physique, blood type, and other criteria.
"Eugonia" collaborates with reputable and qualified sperm banks in Greece and abroad, where donors are selected based on strict criteria, both in terms of their fertility as well as their physical and mental health. All samples are accompanied by the test results and reports of the donors.
Under the current Greek legal framework, a program for egg and embryo donation applies under certain conditions:
Safeguarding the recipients' health
Oocyte and embryo donors must undergo a series of clinical and laboratory tests to ensure that no infections will be transmitted to the recipients. All couples that join the IVF program at Eugonia IVF undergo these same checks.
Donation Anonymity
According to the Greek legislation, egg donation refers to the disposal of the retrieved eggs, after the donor's written consent, for use by one or more recipients. In particular, according to Law 4958/2022-FEK142/A/21-7-2022, the identity of the donors, at the choice of these people, can be anonymous, named or disclosed to the resulting offspring after they reach adulthood, upon request. Additionally, recipients can choose whether they want an anonymous or named donor. Donation of reproductive material between relatives is allowed under certain conditions. Finally, the identity of the offspring, as well as its parents (the recipients), is not disclosed to third party donors of gametes of fertilized eggs. According to the current legislation, it is mandatory to keep track of and register all data concerning donors and recipients in the National Donor Registry of the National Authority of Medically Assisted Reproduction, to ensure traceability of the reproductive material.
Age
According to the Greek legislation, the egg donor must be 18 – 35 years old, while the embryo donor must have not exceeded the age of 40.
Compensation
It is prohibited to provide eggs or embryos in exchange for any kind of compensation to the donor.
Ethical side of the donation
Donations, when they are carried out, are driven by necessity, with the "sacred purpose" of the joy of procreation. We believe that before a couple decide to donate or receive donated eggs or embryos, they must give written informed consent. This is why we provide all relevant information from our very first meeting with the prospective donors and recipients. We believe it is our duty to give you all the time you need to assess all relevant information, discuss among yourselves and decide freely and responsibly. Egg and embryo donation is the highest expression of solidarity towards another couple facing the same problem: infertility. Your decision to donate eggs / embryos will by no means affect the course of your treatment.
Consent of donors and recipients
We follow a strict policy regarding consents. We consider it inconceivable to donate eggs or embryos without the written informed consent of all four parties involved: donors are asked to sign a specific consent form authorizing the clinical team to proceed with the donation; recipients sign a corresponding form declaring that they accept the donation. These consent forms are countersigned by a member of the medical team and are strictly confidential.
Embryo donation is indicated for couples with loss of reproductive capacity (usually both the female and the male partner).
The embryos for donation are provided by a couple who have already undergone in vitro fertilization and have usually completed their family planning. These are surplus cryopreserved embryos, which the donor couple prefers to donate rather than destroy. It is a generous and altruistic act. The decision lies with the donor couple. When they decide to donate, they need to jointly sign a special consent form to declare that they waive all rights and that they are donating the embryos anonymously and without financial compensation to unknown recipients.
According to the Greek legislation, donated embryos must come from a woman under 40 and a man under 50 years old. The couple wishing to receive embryos shall select, in collaboration with the EYGONIA staff, the embryos that match their characteristics as closely as possible. These embryos are thawed and transferred to the woman following the protocol of a standard frozen embryo transfer with or without hormone replacement therapy (ΗRT). From our very first meetings, we provide the recipient couple with the required consent forms, which they must sign before deciding to receive the embryos.
In the field of IVF new knowledge from scientists around the world is added daily, in order to increase success rates. Keeping up to date with new developments is essential.
Our team’s awareness and complete knowledge of the field of fertility is attested by our numerous publications in prestigious scientific journals, oral presentations in scientific conferences and the participation of our scientific team members in European Fertility Societies (ESHRE), besides the international recognition of our researchers.
The exposure to the evaluation and criticism of the scientific community requires us to be constantly updated, as well as to maintain a data-base for the statistics necessary for scientific comparison. These are part of the practice of "evidence based medicine", which is a basic tenant of the Eugonia team.

According to the revised terminology of the International Society for Mild Approaches in Assisted Reproduction (ISMAAR), mild stimulation protocols include a) the natural cycle, b) modified natural cycle, and c) mild stimulation.
Mild ovarian stimulation involves the administration of a low dose of FSH (up to 150 IU/day) for a shorter duration, aiming at the development of fewer follicles and the collection of up to 7 oocytes. Mild stimulation protocols mainly use GnRH antagonists.
However, the use of mild stimulation protocols remains low, mainly because they require a sound knowledge of the GnRH antagonist protocol and optimal laboratory conditions.
At Eugonia we successfully use mild protocols for ovarian stimulation with specific criteria, taking into account the history of each individual couple.
During ovarian stimulation, administration of GnRH analogues maintains a suppression of endogenous hormone levels. In 5-30% of cases there is a premature increase of progesterone on the day of hCG administration (the last injection of the program).
Several studies have shown that the increase of progesterone above 1 ng/ml is associated with reduced pregnancy rates, while other studies have failed to show such an effect. The mechanism through which pregnancy rates may be affected has not been elucidated yet, but is seems that increased progesterone has a negative impact on the quality of the endometrium.
In view of the contradicting data in the literature, it is important to conduct more prospective randomized controlled trials in a large number of patients, in order to clarify the role of progesterone increase on pregnancy rates.
The OHSS is a severe complication of the ovarian stimulation. It is more usual for women with polycystic ovaries and of lower weight.
In case of a very severe type of OHSS, the team of Eugonia applies the revolutionary treatment with the GhRH antagonist administration, after the oocyte retrieval, and during the luteal phase leading to the non hospitalization of the women.
This innovative and causative treatment has replaced:
a) The absence of treatment
b) The incidental and alleviative hospital care with a simple one
As a result of this treatment is the decreased physical discomfort, the psychological and financial cost and the loss of working hours.

During a natural cycle, no drugs are used for the stimulation of the ovaries. The development of the single leading follicle and the maturation of the endometrium are monitored with a series of ultrasounds and hormone tests. Due to a high rate of premature ovulation and loss of the oocyte, the natural cycle has been replaced by the modified natural cycle.
During a modified natural cycle (MNC), antagonist and minimal doses of gonadotrophins are administered in the last days of the follicular phase. In this way premature ovulation is avoided. The advantages of natural cycles are no/minimal drugs, no side effects or complications, short duration, low cost etc.
The disadvantage is that from a single follicle we must retrieve a single oocyte, which must be mature, get fertilized, divide into a good quality, chromosomaly normal embryo with high developmental competence, capable of implanting in the uterus and result in pregnancy.
Indications for natural/modified natural cycle include poor ovarian response, several previous IVF attempts, the desire to avoid drug administration, and some rare contraindications of drug stimulation.
