Donor-Egg IVF Procedure for Recipients – Protocol & Cost

Donor-egg IVF is a fertility treatment in assisted reproduction that allows a recipient woman to achieve pregnancy using the oocytes of an anonymous donor. Egg donation is indicated for women who cannot have children with their own eggs, either because they are too old, or because they suffer from some genetic alteration or any other problem with their gametes.

One advantage of donor-egg IVF, whether with partner sperm or donor sperm, is that it has a high probability of success and that is why more and more women are turning to it to become mothers.

Indications

IVF with egg donation is not usually the first chosen treatment when a woman or couple goes to a fertility clinic, as patients usually want to try for pregnancy with their own gametes first.

Nevertheless, these are the following situations in which egg donation is explicitly indicated:

• Patients with no ovarian function, either due to primary ovarian failure, premature ovarian failure, absence of ovaries or menopause.
• Patients with ovarian function but who cannot use their eggs because of transmissible genetic abnormalities, repeated failures in previous IVF cycles or because they are over 40 years old.

This last cause is the most frequent since with age the quality of the eggs decreases: the probability that the embryos obtained have chromosomal abnormalities that compromise their viability and cause abortions increases. The chances of having a child with Down syndrome are also significantly increased.

When to use egg donation IVF

Chosing the egg donor

Egg donation is a very controlled process. In order for it to be performed, the egg donation candidate must meet a series of legal, medical, and ethical requirements.

A selection process will be carried out to assess her suitability to be a donor, in which both her physical condition and psychological aspects are studied.

It should be noted that this is an altruistic, voluntary and totally anonymous process: the identity of the egg donor will always remain confidential. Related Article: How can I become an egg donor?

Types of Egg donation

Depending on the origin of the eggs, there are two main types of egg donation: fresh egg donation or vitrified egg donation.

However, today we can also include two other types of egg donations in this classification: eggs steming from egg banks and mini-egg donation, or shared egg donation which is also referred as to egg sharing or split egg donor cycle.

In the following section, we will discuss each of them:

Fresh donor egg IVF

In these cases, the donor and the recipient of the eggs must have the hormonal cycle synchronized, so the donor is stimulated while the recipient prepares her endometrium.

In other words, in the same cycle, the donor's eggs are extracted and, after 3 or 5 days, the embryos are transferred to the uterus of the recipient.

Fresh egg donation. Synchronizing donor and recipient

The disadvantage of this technique is that if the donor does not respond well to ovarian stimulation, the recipient may have to wait until the next cycle to perform the transfer, which involves more hormonal medication and greater emotional distress.

Frozen donor egg IVF

This form doesn’t require the synchronization of donor and recipient. First of all, the donor's oocytes are extracted and the mature ones are frozen by using the vitrification technique.

Once a compatible recipient has been found, these eggs are thawed and fertilized with the partner’s sperm or with the sperm of a compatible donor in the case of a double donation.

As in the previous case, the egg recipient will also have to perform an endometrial preparation treatment prior to the embryo transfer, this will not be coordinated with the donor, though.

Frozen egg donation

The disadvantage of this method is that the number of eggs available for fertilization may decrease because not all of them survive the thawing process. The current survival rates are still very good thanks to the optimization of the oocyte vitrification technique.

Eggs from egg banks

As we have already explained in the previous sections, the donor's eggs can be used either fresh or frozen. In case of fresh egg donation it will be necessary to synchronize the cycles of the donor and the recipient. Otherwise, after harvesting the eggs, they will be frozen until the moment of fertilization, at which point the eggs will be thawed.

For the latter option, the fertility clinic can either have its own donors (its own egg bank) or, on the contrary, work in coordination with an external egg bank.

Health management expert Javier Suarez comments on the advantages of external egg banks:

Having an external egg bank for egg donation treatments offers multiple advantages, such as the variety of phenotypes.

An egg bank is a department in charge of obtaining, evaluating and then distributing donor eggs. Due to their activity, the egg banks have a wide and varied database of donors. For this reason, they can respond to almost any demand from clinics.

This allows fertility centers to offer egg donation treatments almost immediately, as it is rare not to find a compatible donor in the egg bank.

Mini egg donation

Mini egg donation consists of the donation of a smaller number of eggs. While in a complete egg donation the recipient obtains all the eggs recovered from the donor, which may be between 8 and 10, in the mini egg donation only 4 or 5 are received.

Medical Director of FIV Valencia, Dr Miguel Dolz, comments on the two purposes of mini egg donation:

Financial aspect

the cost is significantly lower and thus more women and couples are able to access this treatment.

No surplus embryos are generated

Especially in women or couples who only want to have one child through egg donation. Thus, no surplus embryos are created that must later be donated or vitrified, with the consequent storage costs.

Dr. Miguel Dolz also assures that:

The pregnancy rate per cycle performed in a mini egg donation is the same as with a complete egg donation.

Mini egg donation is also known as shared egg donation, since the eggs extracted from one donor can be used for two or more recipients, always in compliance with current legislation which states that no more than 6 children can be born from the same donor, including their own children.

Egg donation procedure step by step

Once the egg donor has been accepted, it is possible to start the egg donation cycle. The whole process takes a few minutes and consists of the following steps:

Ovarian stimulation of donor

The donor undergoes hormonal ovarian stimulation treatment to ensure that more eggs develop than in a natural cycle, in which only one would mature, thus increasing the chances of success.

Then, by means of follicular puncture, the developed eggs are extracted. The mature ones are fertilized in the laboratory with sperm from the recipient's partner or from an anonymous sperm donor which depends on the characteristics of each couple.

The resulting embryos are kept in culture and their development will continuously be evaluated until the day in which the embryo transfer to the recipient takes place.

Endometrial preparation of the recipient

Before the embryo transfer, the recipient needs to get her endometrium prepared so that the embryos can implant in the uterus.

For this purpose, estrogen and progesterone must be administered either orally, vaginally, or in patches so that the endometrium reaches the appropriate thickness (7-10 mm) and becomes receptive.

Medications for the donor-egg transfer to the recipient

The embryo transfer to the recipient's uterine cavity will take place between 3 and 6 days after fertilization. The best quality embryo or embryos will be chosen for transfer and the rest will be vitrified for use in subsequent cycles, either to make another attempt in case pregnancy is not achieved in this one, or to have another child later.

About 10-12 days after the embryo transfer, the levels of the hormone β-hCG are analyzed to find out whether or not pregnancy has been achieved.

Clinical results of egg donation

Because good quality eggs from young, healthy women are used, the success rates of egg donation are higher than those of IVF with own eggs.

Embryologist Rocio Diaz comments on the success rates:

In older patients, we increase the pregnancy rate when they undergo a fertility treatment with young donor eggs.

According to the statistical report published by the Spanish Fertility Society in 2017 (National Registry of Activity 2017-Registration SEF), in the case of fresh donation the percentage of pregnancy by transfer in an egg donation cycle is 54.7% and the birth rate by transfer at 40.6%.

In the case of the donation of frozen eggs, these percentages decreased somewhat, being 40.6% and 28.4%, respectively.

Costs

Performing Egg donor IVF makes the fertility treatment more expensive since the medication to stimulate the donor and financial compensation for the discomfort caused must be paid for.

While an IVF/ICSI treatment with own eggs costs between $10,000 and 15,000, when you add in the donation of eggs, the price can range between $14,000 and 20,000 depending on the fertility clinic and the type of egg donation.

The advantage of egg donation IVF is that high-quality eggs are used and the patient usually achieves pregnancy at the first intent. Therefore, it is possible to save the cost of accumulated cycles that would have to be performed if own eggs were used.

FAQs from users

Fresh egg donation vs. Frozen egg donation- which is one is better?

Egg donation with vitrified eggs has pregnancy rates very similar to those with fresh eggs. The only difference may be in the number of eggs harvested. In addition, it is also vitally important to have the survival rate of egg devitrification.

Can egg and sperm donation be done at the same time?

Yes, it is what is known as double donation. It involves performing an IVF process using both eggs and sperm from donors and not from the intended parents.

What is the number of attempts to achieve success with ovodonation?

There is no fixed number of ovodonation attempts recommended. It will depend on the characteristics of each infertility situation. There are couples who try numerous times and those who throw in the towel after two or three ovodonation processes.

How much does IVF with egg donation cost?

The cost of egg donation depends widely on the country where the patient undergoes treatment.

While in European countries such as Spain, Cyprus, the Czech Republic, Portugal, or Greece it ranges from €3,800 to €5,500 approximately, in others such as Ukraine and Russia, it can be as high as €8,500-11,000. In the UK, however, egg donation costs about £9,500.

As for the USA, it is the most expensive destination, but at the same time the one that offers the possibility of choosing between a known, a semi-known, or an anonymous donor, which is an advantage for many egg donor recipients. On average, the price there reaches $20,000-40,000.

Other popular egg donation destinations around the world are Barbados and South Africa, where the price range is €4,500-5,900.

If I use donor eggs, will the baby look like me?

When matching an egg donor to a recipient, fertility clinics take into account that there is compatibility between them and that they share as many phenotype and immunological characteristics as possible. So, theoretically, yes, a baby conceived with donor eggs is likely to look like the birth mother.

However, it is important to note that the biological mother of the baby will be the egg donor, so in terms of genetic inheritance, the answer to this questions is no, the baby will not look like the recipient, since he or she does not share the genetic load with her.

How does epigenetics affect egg donation?

Epigenetics refers to the changes that can occur in gene expression caused by environmental factors. Therefore, although in cases of ovodonation the genetic endowment of the embryo comes from the egg donor, during gestation, the maternal environment can influence the expression of these genes.

The experiences I have read of mothers through ovodonation coincide in that they tell their children about the process, but I have doubts, do experts recommend telling their children about it?

The decision to tell your children is a very personal one. However, it is a controversial topic and in general, experts recommend telling your children.

What are the risks of egg donation for recipients?

The main risk of egg donation for recipients is becoming pregnant with multiples if more than one embryo is transferred. To avoid this, recipients are encouraged to bet on a single embryo transfer (SET), as the high quality of the eggs used guarantees a high success rate even with a SET. As for the side effects derived from the medications for endometrial preparation, these are considerably lower than those associated with the medical process for egg donors.

Is donor-egg IVF with PGD for gender selection an option?

Sex or gender selection is not allowed in every country. Thus, the availability of IVF with PGD for gender selection depends on the location of your fertility clinic. Most patients who wish to select the gender of their baby-to-be travel to the United States to do so, as the majority of laws by state are favorable to its performance.

Embryos can be genetically biopsied with PGD prior to fertilization with IVF. Once one cell of the embryo is removed, its chromosomes can be analyzed to detect potential genetic defects and determine the embryo's gender. Then, only the embryos of the desired gender are selected for the transfer.
