How Is an Egg Donor Selected?

The first question couples put to their doctor once they decide on donation is almost always the same: "Who will the donor be?" It is an entirely natural question, because you are entrusting the most personal part of the process to someone else. The good news is this: donor selection is not a random draw but a controlled process shaped by medical criteria, similarity matching and your approval. Most couples have already answered the question of what egg donation is before reaching this point; now comes the most human question of the whole journey. In this article we explain who can enter the donor pool, which criteria matching is based on, and how your say is protected at every step.

This content was prepared under the medical supervision of Op. Dr. Armağan Ulubaş.

Who Can Enter the Donor Pool?

The foundation of a successful egg donation treatment is being certain of the donor's health. For this reason, not every candidate is accepted into the pool; candidates go through a multi-stage selection before being included in treatment. The core requirements we look for in a donor candidate are:

• Young age: Donors are typically in their 20s. Young eggs are at their most productive period in terms of both number and quality; this is the first condition behind success rates of up to 90% in donation.
• Comprehensive health screening: A general health check, hormonal assessment and gynaecological examination confirm the candidate's suitability for treatment.
• Infection tests: Screening for infectious diseases, above all HIV and hepatitis B and C, is mandatory for every donor.
• Genetic screening: Genetic assessment is carried out for the risk of hereditary disease, and family history is questioned in detail.
• Psychological assessment: We make sure the candidate understands the meaning of donation and is taking part consciously and voluntarily.
• Fertility history: Priority is given to candidates who have had their own healthy pregnancy or whose fertility has been proven.

Thanks to this selection, every profile that reaches you is one that has already been medically approved before you even see it. Whether the treatment is right for you is a separate question; we covered that in detail in our article on who egg donation is for.

Matching Criteria: A Donor Who Resembles You

Medical selection determines entry into the pool; but what determines the right donor for you is similarity matching. In matching, our priority is the mother-to-be: the aim is to find the donor whose physical features are closest to yours. The main criteria taken into account are height and weight, skin colour, eye colour, hair colour and texture, and blood group. Blood group compatibility matters to couples who want the family's blood group picture to look natural, and it is taken into account in planning. Let us underline a realistic point here: matching is not a search for a "copy" but a search for harmony. The aim is not to find someone who shares your exact face; it is to ensure that features which are decisive in heredity — such as skin, eye and hair colour — are consistent with your own family line. For women who are not yet ready to give up their own eggs, a tandem cycle, in which both their own and donor eggs are used in the same cycle, can be an intermediate option; in that case the donor is selected by the same criteria.

Confidentiality: Identities Are Never Shared

The most sensitive heading in donation is confidentiality, and here the rule is clear: anonymity is two-way. You cannot learn the donor's identity at any stage; and the donor can never know who you are, whether the treatment took place, or its outcome. Only the features used for matching are shared with you. In North Cyprus, egg donation is carried out within a legal framework, in centres subject to official oversight; confidentiality is not a courtesy promise but a legally protected obligation. This two-way protection permanently safeguards both your family privacy and the donor's personal life.

The Donor Selection Process Step by Step

So how does all this work in practice? The part couples most want to know is how much say they have. The answer is clear: at Clavis, donor selection advances in four steps and control rests with you at every step; no match is finalised without your approval:

• 1. Criteria form: Features such as your height, weight, skin, eye and hair colour and blood group are recorded, and you discuss any specific expectations with your doctor.
• 2. Matching suggestion: Our team identifies the profile from our broad donor pool that best fits your criteria and presents it to you without any identifying details.
• 3. Your approval: If the suggestion does not feel right, you share your reasons and a new match is prepared. The right to approve always belongs to the couple.
• 4. Donor stimulation: After your approval, the donor's ovaries are stimulated and the treatment schedule is planned in sync with your own preparation.

"Who Will the Baby Resemble?" and Why Cyprus

The honest answer to this question has three layers. First, genetically the baby develops from your partner's sperm and the donor's egg; the father's side of the genetics is entirely your family's. Second, because the donor was already selected according to your physical features, resemblance is not left to chance. Third, and the point most couples overlook: your body nourishes and grows the baby for nine months; the epigenetic effect of the uterine environment on gene expression belongs to the mother. In other words, the contribution of the mother who carries the baby is not an emotional consolation but a biological fact. We never judge any couple who asks this question in our clinic; on the contrary, talking openly about this concern is part of a healthy decision-making process.

Because egg donation in Cyprus is carried out within a legal framework, couples can plan this process with confidence and without getting caught up in waiting lists. At our clinic in Nicosia, a team with more than 23 years of experience that has accompanied over 45,000 families combines MINC+ incubators, uninterrupted embryo monitoring with embryoscopy, and vitrification technology reaching 99% survival on thawing. Thanks to a broad donor pool, you do not have to compromise on your matching criteria, and the length of stay in Cyprus is limited to 5-7 days for most of our patients. To clarify your treatment budget you can look at our egg donation cost page, and by sending your test results to our doctor through the free assessment form you can start discussing your personalised matching plan today.

Frequently Asked Questions

Can I find out who the donor is?

No. Under the legal framework in North Cyprus, donation is carried out on a two-way anonymity principle: you cannot learn the donor's identity, and the donor can never know your identity or the outcome of the treatment. Only the characteristics used for matching — such as height, weight, skin, eye and hair colour and blood group — are shared with you.

What tests do donors undergo?

Before being accepted into the pool, every donor candidate goes through comprehensive health screening: infection tests such as HIV and hepatitis, genetic screening, hormonal and gynaecological assessment, and a psychological interview. Donors are also typically in their 20s and are expected to have a healthy fertility history.

Will the baby look like me?

Genetically, the baby develops from your partner's sperm and the donor's egg; however, because the matching is based on your skin, eye and hair colour and your physical features, family resemblance is taken into account. In addition, your body nourishes the baby throughout the pregnancy, and the epigenetic effect of the uterine environment on gene expression belongs to the mother.

What happens if I don't approve the suggested donor?

No match is finalised without your approval. If you feel the suggested donor profile is not suitable, you share this with your doctor and a new suggestion that fits your criteria is prepared from the pool. Donor stimulation only begins after you have approved the match.
