What is embryo adoption?

Embryo adoption

If you have never heard of embryo adoption, this article IVF-Spain Madrid will be of particular interest to you. It is a cheaper alternative to other treatments of reproductive medicine. You will save not only money, but also time, as the duration of the treatment (in other words, the stimulation time until the embryo transfer) is also much shorter. The success rates of this treatment method are as high as those of IVF with double donation of gametes (egg and sperm donation).

Embryo adoption is…

Embryo adoption is a simple and very effective technique of assisted reproduction. It involves the adoption of embryos created during fertility treatments of other patients. Nowadays, reproductive medicine techniques are so advanced that pregnancy is often achieved with the transfer of only one embryo. The surplus of high quality embryos is therefore the result of the extraordinary success of reproductive medicine. Once family planning is complete, our former patients donate these surplus embryos to help others.

Will I have to undergo an ovarian stimulation?

Another advantage of this type of treatment is that the patient does not need to undergo an ovarian stimulation, which is always the case during a normal IVF with your own eggs. This type of stimulation is usually the most difficult part of a treatment, which can be very stressful both physically and emotionally.

In the case of embryo donation, the patient also takes medication to stimulate the lining of the uterus, but at a much lower dose. These drugs are taken orally, contrary to IVF.

Moreover, the costs of such a treatment are much lower, because not only the stimulation but also such costly components of an IVF treatment as egg fertilization, incubation period of embryos in a lab, etc. are omitted.

Where do these donated embryos come from?

The donated embryos come from couples who have already undergone a fertility treatment at our clinic. These may be treatments with their own eggs or with donor gametes (egg and/or sperm donation). After completing their family planning, these patients donate the remaining embryos for reproductive purpose (i.e. for other couples or single women).

Embryos frozen in liquid nitrogen can survive for an indefinite period of time. Embryo donation as a fertility treatment has existed for around 20 years.

Steps of embryo adoption

As we have already mentioned, the adoption of embryos is a faster process, as several phases of a normal IVF are skipped:

  1. First consultation: during the initial consultation you will receive a diagnosis and have the opportunity to ask the doctor any questions you may have regarding the embryo adoption.
  2. Preparation of the endometrium: with 10-12 days of taking oestrogen and progesterone, the patient’s endometrium is prepared for the embryo so that it can implant without any problems.
  3. Embryo selection: all embryos are stored in a cryopreservation tank. The selection of the best embryo is based on the following characteristics: Phenotype, blood group and rhesus factor.
  4. Embryo transfer: on the day of the embryo transfer, the agreed number of embryos is thawed and transferred to the patient. The Spanish Society of Fertility allows up to three embryos, our technology and recommendation is to transfer a single embryo.
  5. Pregnancy test: 10 days after the embryo transfer, the pregnancy test is carried out by taking a blood sample. If the BETA hCG level is high, it means that the embryo has been successfully implanted.
  6. First ultrasound: in about 12 days after a positive pregnancy test, the first ultrasound is performed to confirm the normal course of the pregnancy. At IVF Spain Madrid we accompany our patients until this first ultrasound scan to make sure that everything goes well.

What are the advantages of embryo adoption?

Embryo adoption is a good option especially for those patients who have already had several failed IVF attempts.

Shorter process. First of all, as is the case with all our fertility treatments, there are no waiting lists. Moreover, the duration of the process is further reduced, as the embryos are already cryopreserved and ready to be transferred.

Simple preparation. Endometrial preparation for this treatment is very simple and convenient as it consists of transdermal oestrogen patches or oral and vaginal progesterone tablets. These drugs are also taken in the first weeks of pregnancy to support the pregnancy.

Few clinic visits. An ultrasound scan is sufficient to determine the best time to perform the embryo transfer. Patients can have this ultrasound performed in their home town. This means they only need to come to the clinic for the embryo transfer.

High success rates. Thanks to the improvement of cryopreservation techniques, the embryo survival rate is about 95%, the pregnancy rate about 45% and the implantation rate about 36%.

Cost reduction. The favourable price of the treatment is a great advantage. Neither the selection of a suitable donor nor controlled ovarian stimulation is necessary, and the work of the laboratory is limited to thawing, evaluation and embryo transfer.

Another reason. The last advantage has a special meaning. On the one hand, it is very nice that there are people who altruistically donate their embryos to help other people. On the other hand, it is incredibly nice that there are people who give these embryos a chance to develop into a new life.
