Embryo adoption or embryo donation is a simple treatment performed thanks to embryos donated by patients who did not need to use them in their treatment. In an in vitro fertilization (IVF) cycle, several embryos are cultured and among those that reach the blastocyst stage, only one of them is transferred to the patient and the remaining ones are vitrified for subsequent treatments. These embryos can be donated so that other patients have the possibility of forming a family.

At Ovoclinic, we have more than 20 years of experience in all types of highly complex assisted reproduction treatments. For us, our priority is to achieve your dream together. In addition, our success rates are above average and we have Pregnancy and Birth Guarantee Programs for greater peace of mind and security.


  • Patients who want a simpler assisted reproduction treatment.
  • Couples in which both members have fertility problems.
  • Single women with low ovarian reserve or poor oocyte quality who cannot resort to IVF with donor semen.
  • Patients suffering from repeated miscarriages or implantation failures.
  • Couples that have genetic incompatibility.


En primer lugar, se lleva a cabo un tratamiento de preparación endometrial mediante estrógenos, coincidiendo con el periodo menstrual de la paciente. Esta fase suele durar entre 12 y 14 días, hasta que el endometrio alcanza un grosor adecuado para recibir al embrión.

El mismo día de la transferencia, el embrión es desvitrificado en el laboratorio y luego transferido al útero de la paciente mediante una cánula muy fina. Se trata de un procedimiento indoloro que se realiza sin sedación.

En torno a 14 o 15 días después de que se haya realizado la transferencia del embrión, se debe realizar el test de embarazo para comprobar que el tratamiento haya sido exitoso.

En caso de dar negativo en el test de embarazo, se puede repetir el proceso transcurrido un periodo de tiempo prudencial.


Who can donate an embryo?

There are a number of requirements that must be met for patients to donate their embryos to other couples. Firstly, the eggs must come from a woman under 35, in order to have high chances of pregnancy. In addition, negative serologies and normal karyotypes are required.

What physical compatibility will the donated embryo have with me?

In the case of embryo adoption we look for compatibility of blood groups and physical characteristics with patients, however it isn’t as easy to match as accurately as with egg donation or double donation. In this type of treatment we wouldn’t be able to use Ovomatch, for example.
