IVF/ICSI
With Egg Donation

One of the first steps is to perform tests and exams. Your physician needs them to assess your clinical status. These may include a gynaecological ultrasound, hormone tests or infectious disease screening or a sperm count. After assessing them, your physician will decide which treatment is most appropriate to your diagnosis.

Before you go ahead with treatment with donated eggs, you will be asked to attend a psychological counselling appointment at our clinic (with your partner, if applicable). Although it is compulsory, it is just a counselling session to discuss the legal, emotional and social implications of this type of treatment.

In this phase of your treatment, you will be contacted by a member of our team about the selection of the right egg donor for you. The selection will be based on your physical characteristics and blood group.

All our donors are selected on the basis of strict minimum requirements:

• They must be healthy women in accordance with the requirements of our own National Medically Assisted Procreation Council (CNPMA).

• They must be under the age of 34.

• They must have no personal or family history of hereditary diseases.

All donors attend a psychology appointment for a confidential discussion of personal, psychological and social aspects of the donation process. The aim is a conscious, informed, responsible decision to donate.

We have a wide range of egg donors and even if it is not possible to find you a donor immediately, the waiting time will not be too long. At AVA Clinic you can have treatment with fresh or frozen donor eggs. This helps shorten your waiting time when selecting an egg donor.

As soon as your egg donor has been selected, you are ready to begin your treatment. The total duration of your treatment will depend on whether you use fresh or frozen eggs. The use of frozen eggs normally takes less time.

The first step in your treatment is the hormonal preparation of your uterus to receive the embryos that will be created from the donated eggs and sperm (from your partner or a sperm donor, if necessary). This preparation will be synchronised with the egg donor’s menstrual cycle if you are using fresh eggs, or with the thawing of the eggs, if frozen.

A few days before your uterus is perfectly prepared to receive the embryos, the donor’s fresh eggs will be collected or the frozen donated eggs will be thawed.

Eggs with the right degree of maturity will be retrieved or thawed for fertilisation in the lab. These are then stored in the lab under conditions similar to those of the human body. These conditions are perfect for fertilisation and subsequent development of the resulting embryos.

On the same day as the retrieval or thawing of the donated eggs, your partner will provide a semen sample so that the eggs and your partner’s sperm can be combined in the lab. The sample is provided by masturbation in the total privacy of a special room for that purpose.

In very special cases where collection of sperm from ejaculate is not possible (e.g. azoospermia, inability to ejaculate), it may be necessary to collect sperm directly from the testicular tissue in a biopsy.

After assessing the sperm, our embryologists will use lab techniques to select the ones with the best motility and morphology. There are a number of techniques to improve sperm samples and our embryologists will make sure that they choose the most appropriate one for you.

The eggs will be fertilised with the selected sperm on the same day of the egg collection/thawing. The technique of choice for this type of treatment is ICSI. One sperm per egg is selected and injected into it. We use special, high-precision equipment (microscopes, microinjectors and microneedles) for this procedure to ensure that we achieve good fertilisation rates.

The day after egg collection/thawing, one of our embryologists will contact you with news about your treatment. You will now find out how many embryos will be developing over the next few days. During this culture period, which may vary from two to five days, your embryos will be safe in our lab and our embryologists will ensure that they have the ideal conditions for their development.

The embryologists will decide on the best day to schedule the transfer of your embryo(s) to the uterus. This decision will depend not only on the quantity but also the quality of the embryos. The embryologists will conduct a careful assessment of each embryo every day to ensure that the best ones are chosen on the day of your embryo transfer.

While your embryos are being cultured in the lab you will be taking medication to help prepare your uterus to receive the embryos. It is important for you to keep taking this medication until your physician or one of our nurses tells you otherwise.

On the day of your embryo transfer, our embryologists will inform you on how many good-quality developing embryos you have. If there are more good-quality embryos than you want to transfer, our embryologists will cryopreserve them for future use (vitrification method). Cryopreserved embryos remain intact and at the same stage of development until they are thawed. Around 95% of embryos are totally unaffected by this freezing and thawing process.

At AVA Clinic you will be given the choice of transferring one or two embryos. However, we will probably advise you on the ideal number to transfer in order to achieve a healthy pregnancy and delivery.

The transfer procedure is performed in the operating theatre. No anaesthesia is necessary in this case, as it is practically pain-free, much like a gynaecological examination. The embryos are transferred to your uterus via the cervix by means of a very thin catheter. With the aid of an ultrasound probe, your embryos are placed directly in the place where they should implant to result in a pregnancy.

Today’s the day! After what we know is a difficult wait, it’s time to do the long-awaited pregnancy test. The test is normally conducted about two weeks after the donor egg collection/thawing. You will have to take a blood test to confirm your pregnancy. You can take the test in the comfort of our clinic though, if this is not convenient, you can do it at any lab testing facility.

The AVA Clinic team wishes you the best of luck with your treatment. And don’t forget that you can contact us at any time if you have any questions.
