Ovodonation consists of performing In Vitro Fertilization, using a donor's eggs together with the couple's sperm. It is also possible to perform this technique with donor sperm.
Embryo adoption consists of transferring existing embryos that have been donated by other patients for reproductive purposes. These embryos come from healthy patients, under 35 years of age, who have successfully undergone In Vitro Fertilization treatment and have fulfilled their genetic desire. In many cases they come from egg and/or sperm donors.
The main difference between Ovodonation and Embryo Adoption is the possibility of using the couple's sperm for fertilization, which is impossible in embryo adoption. In addition, all the embryos generated in a cycle after the fertilization of the eggs belong to the patient, and vitrified embryos may remain after the embryo transfer. The rest of the process, both in terms of treatment for the patient and success rates, are very similar for both procedures.
