Clinica Tambre’s patients and their wishes always come first and with this in mind, they ensure that all treatments follow a strict and careful protocol to always be able to provide the best results
One of the treatments that many couples or single women follow is egg donation. This technique creates an embryo through the donation of another woman’s egg when it is not possible to conceive using your own eggs
Clinica Tambre explain here how they go about selecting their donors
It is a very strict process as it is something that is so very important to egg donation patients who want a healthy baby and a child resembling their looks. Women who decide to donate their eggs at Clínica Tambre must meet a series of rigorous requirements. In fact, many donors are discarded during the selection.
There are several departments within Clínica Tambre involved with egg donor selection and here the professionals explain their roles in this important process.
Maribel Carrasco, nurse
The nursing department is the first to get to know the a potential donor and who acquires the donor’s medical history. Nurses will accompany the donor throughout the process and will follow up after the egg collection to ensure that the eggs are suitable for treatment.
“The nursing department guarantees that the donation is an anonymous and altruistic process, in which the identity of the donor will never be revealed,” Maribel explains. “As a general rule, the profile of women who decide to donate their eggs are patients between 18 and 26 years of age, caucasian, and many of them are university students.”
Dr Silvia Moreno, psychologist
To ensure that the mental state of the donors, as well as their psychological family history are healthy and positive, they undergo a structured diagnostic interview. This psychological test helps to ensure the safety of the donors with their decision, as well as prevention of the transmission of any disorder or important anomaly in any future baby.
A woman will be excluded from the donation process if a family psychiatric or psychological background is detected. It is also the same if a criminal record or consumption of toxic substances is identified and equally if there is a chance that anything could be genetically inherited which may affect the quality of their eggs.
Dr Moreno tells us that, in addition to the structured interview, a complete personality test is carried out, that objectively serves to detect serious disorders that may be hereditary or alter the quality of the eggs.
The doctor also reveals that the reason donors give for donating is usually the desire to help other women or couples to fulfill their dream of having a family.
Dr Elena Santiago, gynaecologist and fertility specialist
Once the first steps have been done, a complete gynaecological examination is performed. Afterwards, they will undergo a general health analysis including tests for sexually transmitted diseases as well as a karyotype and a genetic study of recessive mutations. Dr Santiago shares that there is the possibility of extending the study to more than 300 genes involved in recessive diseases (genetic matching) to compare the donor with the male (partner or sperm donor) and rule out that they have the same mutations, therefore reducing the risk of having a child affected by a disease of this type.
Susana Cortes, lab director
In the laboratory we carry out all the analyses and genetic tests necessary to ensure that the recipient mother receives the best eggs for her. From the anonymous donor that corresponds best to her physical characteristics and, at the same time, totally preventing the possibility of transmitting a disease.
Once we have selected the donor and the egg donation treatment begins, we use the sperm sample from the partner, or sperm donor, to aim to fertilise the collected eggs in the laboratory on the day of the egg retrieval.
During the following days after the fertilisation, we carefully supervise the embryo development until they achieve blastocyst status (after five or six days). Embryologists then choose the best quality embryo for the transfer and if there are good quality embryos remaining, we would then freeze them.
Thanks to the effort of the medical team at Clinica Tambre, and the help of the young and healthy egg donor, women who, for different medical reasons cannot get pregnant with their own eggs, will be able to receive anonymous oocytes and fulfill their dream of motherhood
