Egg Donation Clinic in Madrid

Egg donation treatment is an assisted reproduction technique involving in vitro fertilisation (IVF), in which fertilisation takes place outside the woman’s body. In this procedure, the eggs come from an anonymous donor, whilst the sperm may be from the partner or a donor, depending on the individual case.

Egg donation is a suitable option for women wishing to become single mothers, heterosexual couples and female couples, offering a safe and effective alternative to help you achieve your goal, which is also ours. At our assisted reproduction clinic in Madrid, we support every reproductive journey with respect, empathy and professionalism.

What are the chances of getting pregnant with egg donation?

In vitro fertilisation using donor eggs has one of the highest success rates among assisted reproduction treatments. This is because the eggs come from young, healthy women with high reproductive capacity, which significantly increases the chances of pregnancy.

At our clinic in Madrid, the success rate stands at 56.8%, and it is particularly noteworthy that there are no significant differences in the results based on the recipient woman’s age. Egg donation thus offers a high probability of achieving pregnancy, even in cases where other treatments have not been effective.

The egg donation process, step by step

Before starting any treatment, it is essential to have an initial consultation with a doctor. During this appointment, the specialist will review your medical history and request the necessary tests to assess whether the treatment is suitable for you, whether you are attending as a couple or individually.

Once this assessment has been completed and it has been confirmed that egg donation is the most suitable option, our patient care team will contact you to explain the process in detail and provide you with information regarding the treatment and its cost, supporting you every step of the way in a clear and approachable manner.

To ensure the highest standards of safety and treatment quality, the eggs used in egg donation come from carefully selected donors. All donors undergo thorough medical, gynaecological and genetic screening, which rules out a wide range of hereditary conditions and ensures good reproductive health.

In addition to the clinical assessment, the quality of the oocytes and the suitability of each donor are evaluated. When allocating eggs to each patient, blood compatibility and phenotypic similarity are taken into account, with the aim of achieving the greatest possible affinity and ensuring a safe and personalised treatment.

Before fertilisation and the subsequent embryo transfer take place, the recipient woman undergoes hormone treatment designed to prepare the uterus to facilitate embryo implantation.

This phase involves medical monitoring via ultrasound scans, the administration of oestrogen and progesterone, and blood tests to ensure that the endometrium is in optimal condition. The entire process is carried out in a controlled and personalised manner, ensuring that the timing of the transfer is optimal to maximise the chances of pregnancy.

Once the recipient has been prepared and the donor’s eggs have been retrieved, fertilisation takes place in the laboratory via in vitro fertilisation (IVF). The eggs are fertilised with the partner’s sperm or that of a donor, depending on the individual case, using the most appropriate techniques to promote embryonic development.

Following fertilisation, the embryos are cultured in the laboratory for several days under strictly controlled conditions, allowing their development and quality to be assessed. During this period, the embryology team selects the embryo or embryos with the greatest potential for implantation, thereby increasing the chances of pregnancy.

Fertilisation and embryo development are monitored using advanced systems such as time-lapse, which allow the embryos’ development to be assessed continuously. This embryo monitoring is a key phase of egg donation treatment, as it ensures that the transfer to the recipient’s uterus takes place under the best possible conditions.

Embryo transfer is a simple, painless procedure in which the selected embryo is placed into the recipient’s uterus using a fine cannula. This step is carried out at the optimal time, as determined in advance by medical monitoring, to promote implantation.

Embryo transfer does not require anaesthesia or sedation. After the procedure, the patient can resume her daily life as normal, following the recommendations provided by the medical team.

This step is one of the most important moments in egg donation treatment, as it marks the start of the process of embryo implantation in the endometrium.

Following the embryo transfer, there is a waiting period of approximately 10 to 14 days, during which progesterone treatment continues to support successful embryo implantation.

At the end of this period, a pregnancy test is carried out, which can be performed via a blood test for the beta-hCG hormone, providing an accurate and reliable result. If pregnancy is confirmed, the medical team will schedule the first check-ups to ensure proper monitoring from the earliest weeks.

This final step concludes the egg donation process, supporting the patient with care and professionalism at a crucial stage of the treatment.

FAQs

Frequently Asked Questions about Egg Donation

Egg donation is a form of assisted reproduction involving in vitro fertilisation (IVF) in which the eggs come from an anonymous donor, whilst the sperm may come from the partner or from a donor. It is an effective option for women who are unable to use their own eggs.

Egg donation is recommended for women with low ovarian reserve, a history of failed treatments, genetic disorders, or advanced maternal age, as well as for single women wishing to become mothers and female couples.

Yes. Egg donation is anonymous, in accordance with current Spanish legislation. Donors are carefully selected and undergo rigorous medical and genetic screening.

Donors are selected on the basis of blood compatibility and physical characteristics, always with the aim of ensuring maximum safety and compatibility with the recipient.

Egg donation has one of the highest success rates in assisted reproduction. At FIVMadrid, the pregnancy rate stands at approximately 56.8%, with no significant differences based on the recipient woman’s age.

The duration of treatment may vary, but it generally lasts between 4 and 6 weeks, from the start of endometrial preparation to the pregnancy test.

No. Embryo transfer is a quick and painless procedure, similar to a gynaecological examination, and does not require anaesthesia or sedation.

You do not need to stay completely at rest. It is recommended that you take it easy and avoid strenuous activity on the day of the transfer.

If the treatment is unsuccessful, the medical team will review the case and consider the available options, which may include transferring vitrified embryos or planning a new cycle.

The pregnancy test is carried out 10 to 14 days after the embryo transfer, usually by means of a blood test for the hormone beta-hCG.

Yes. Even if the eggs come from a donor, the woman carrying the baby plays a vital role in its development. During pregnancy, the uterine environment actively influences the expression of the embryo’s genes through epigenetic mechanisms.

Epigenetics acts as a ‘switch’ that can activate or silence certain genes, and is influenced by factors specific to the pregnant mother, such as her diet, her state of health, her lifestyle and the intrauterine environment. This means that the recipient woman contributes directly to how the baby’s genes are expressed, influencing physical and functional aspects.

Furthermore, the donor is selected on the basis of physical similarity and compatibility with the recipient, which also promotes a resemblance. For all these reasons, egg donation not only allows a woman to experience pregnancy and childbirth, but also involves genuine biological participation in the child’s development.
