Who requires an egg donation treatment?
Some of the causes requiring patients to undergo a treatment with donated gametes are:
- Women with a depleted ovarian reserve (which can be caused by premature ovarian failure, endometriosis, surgery or other aggressive treatments), or women with poor oocyte quality (usually due to advanced maternal age), which prevents obtaining embryos with sufficient quality to achieve a pregnancy.
- Women with genetic problems, which they do not want their offspring to inherit.
Stages of egg donation
To coordinate the cycles of the donor and the recipient, both women usually take the pill. If the recipient still has periods, we will have to render her ovaries quiescent so her hormones do not interfere with the treatment.
We will prepare the recipient’s endometrium with estrogen (oral or with patches) and two or three ultrasound scans will be performed during the preparation period to confirm if the thickness and the structure are adequate.
After the fertilization, the biologists observe the development of the embryos in the lab day after day and they report the progress to the patients every day. The biologist’s job is to select the best embryo/embryos to transfer based on their aspect, number of cells and development times.
La transferencia de los embriones al útero se realiza entre dos y cinco días después de la punción en función del desarrollo embrionario. El número de embriones transferidos (de uno a tres) se decidirá en función de la calidad embrionaria y de las características de cada pareja. Esta decisión se toma siempre en consenso con los biólogos, los médicos y los pacientes. La transferencia se hace vía vaginal, sin sedación, y permite depositar el embrión en el fondo del útero, para su futura implantación. La paciente hará la prueba de embarazo unos 15 días después de la transferencia.

How can I improve my pregnancy chances?
Egg donation at ProcreaTec, OvoDona
The ProcreaTec team will select a donor based on the physical attributes of the recipient, as well as her blood type. Once all of the necessary tests have been performed and the donor’s good health has been evaluated, the process to prepare the recipient begins.
ProcreaTec’s egg donation program is called Ovodona. This program has been designed to care for our donors all throughout the process, monitoring their progress every step of the way in order to resolve any complications or concerns that may arise.
Additionally, our stimulation protocol is not aggressive; it is done in such a way that it allows our donors to continue their regular day-to-day life during the procedure, experiencing minimal secondary effects.
Egg donors are young, healthy psychologically stable women that have previously undergone numerous tests to ensure they do not have any important diseases, contagious infectious pathologies nor genetic alterations.
At ProcreaTec we follow the Spanish legislation that allows anonymous egg donation according to the 14/2006 Law on Human Assisted Reproduction Techniques.
Egg Donation Cost
Thanks to the continuous investment in the latest technology, every stage of the treatment is performed at the clinic, which reduces the waiting times and increases the chances of pregnancy.
- Donor preparation
- Ovarian stimulation monitoring: coordination and medical follow-up
- Lab Work
- Intracytoplasmatic Sperm Injection (ICSI)
- Embryo transfer
If the patient decides to interrupt the treatment, we commit to reimbursing the portion of the treatment that has yet to be completed.
The monitoring of the treatment is done in an efficient and secure way, maintaining patient privacy.
Frequently Asked Questions
The ROPA method is a variation of In Vitro Fertilization, which stands for “partner egg reception” or egg donation (in Spanish). It is the most interesting alternative to achieve maternity in female couples.
This method allows both women to participate actively in the creation and birth of the baby. It consists of extracting and fertilizing the eggs of one of the women and transferring the embryo in the partner’s uterus.
As a result, both women play a fundamental role in the gestation and birth of their child; one will be the biological mother (providing the egg) and the other will be the gestational mother (the one who gets pregnant and gives birth).
“A woman can use or be the recipient of [assisted reproduction] techniques regulated in this Law, independent of their civil status or sexual orientation”, states the legal text about human reproductive techniques, passed in Spain in the year 2006.
“The process is the same in the case of a mother or a spouse that undergoes a double gamete donation. In other words, the person who has a baby using a donor egg and the sperm from another donor. The main difference is that the egg comes from the woman’s (female) partner, who has to undergo a stimulation and extraction of eggs”, clarifies Dr. Lourdes López Yañez, Assisted Reproduction specialist and ProcreaTec Co-Founder.
We can have an idea of whether a woman ovulates based on the patient’s menstrual cycle characteristics. Usually, we assume that if a woman has regular cycles, she also ovulates regularly.
All things being normal, in the beginning of the cycle, a follicle containing an egg (or an oocyte) grows. The egg is then released from the ovary to the fallopian tube in a process known as ovulation. After ovulation, progesterone levels rise making the endometrium transform in order to be able to accommodate de fertilized egg. If we measure progesterone levels between days 7 and 9 after ovulation, we will know whether the patient ovulated.
Additionally, it is important to measure other hormones (such as Prolactine or TSH) because they can interfere in the normal egg growth process or in the ovulation.
Ovulation disorders are due to an endocrine imbalance that makes it impossible for the ovary to work properly. Many times ovulation disorders are linked to obesity or being underweight, acne and excessive hair growth. One of the most frequent causes of this disorder is the Polycystic Ovary Syndrome (PCOS). It is estimated that 3-10% of the female population has PCOS. The woman usually suffers from irregular cycles, fertility problems and/or excessive hair growth.
The ovaries look like they contain small cysts that are actually follicles which do not cyclically mature. Women who suffer from PCOS ovulate less than fertile women or they do not ovulate at all. If there is no ovulation, pregnancy cannot be achieved. The goal of treatments for women with PCOS is to make them ovulate at a predictable moment.
If there is a resistance, sometimes pregnancy is achieved only through oral treatment (Metformina), but most of the times, it is necessary to resort to more sophisticated treatments. Everything depends on the level of difficulty to reach ovulation. The doctor, along with the couple, will decide on the best treatment.
Fertilization (when the sperm penetrates the egg) takes place in the Fallopian tube. If both tubes are obstructed, no sperm can reach the egg to fertilize it. The tubes may become obstructed for many reasons. Sometimes the obstruction is due to a previous infectious process like pelvic inflammatory disease or abdominal surgery. The patient usually has no symptoms. Obstructed Fallopian Tubes are diagnosed by hysterosalpingogram.
Hysterosalpingograms are performed (or not) depending on the age of the woman and depending on whether other causes of infertility have been found.
The treatment recommended after tubal patency has been confirmed or not will depend not only on if one or both tubes are obstructed but on many other factors.
Sometimes on the ultrasound scan, accumulated liquid in one or both Fallopian tubes is observed. This is called hydrosalpinx and can be the cause of infertility. Hydrosalpinx increases the risk of infection. Studies show that there is a higher pregnancy rate when hydrosalpinx is removed before a fertility treatment.
