The donor must meet the following requirements, established by law:
- Have a genetic study according to the requirements of the prevailing law
- No abnormalities in the reproductive system
- No general illnesses
- Not have infectious diseases with risk of contagion and be psychologically fit
At Fertty our donors undergo a complete physical and psychological evaluation that will give us information about their state of health and their potential fertility, as well as a genetic study according to the current law, and the study of infectious diseases (HIV, HCV, HBV, Syphilis and CMV).
Donation is a a completely anonymous, voluntary and altruistic process in which the identities of the donor and recipient cannot be revealed. The donor’s information (necessary for the correct follow-up of the pregnancy) will be her age and her blood group and RH.
In order to receive the embryos, the recipient will have to undergo a hormonal treatment of endometrial preparation for implantation to take place. This treatment can be can be carried out in two ways:
- With fresh donor oocytes: the recipient starts the treatment at the same time as the donor (synchronised)
- With frozen oocytes from a donor: this allows greater freedom for programming of the cycle and less risk of cancellation, due to cancellation of the donor (poor response or other reasons).
The semen sample is obtained on the same day as the puncture of the donor or the thawing of the eggs (if vitrified) and is processed in the laboratory in order to inseminate the donated eggs. Once the embryos have been obtained, our biologists are in permanent contact with the couple or patient to inform them of their development until the day of the embryo transfer.
The embryo transfer is performed between 3 and 5 days after the eggs are obtained, transferring the eggs into the uterus of the recipient mother. This simple procedure is performed inside the laboratory using a catheter to insert the embryos through the cervix. This technique does not cause any pain or require anaesthesia and the woman can leave the clinic within a few minutes. The next day, the woman can engage in normal activityand the embryos that have not been transferred are frozen for future cycles.
