The ROPA method , which responds to the acronym of Oocyte Receptor of the Couple , is a modality included within the possibilities of assisted reproduction, by which, in a couple of women, one of them provides the oocytes and the other is the recipient of the embryos formed.
In the couples of women it is necessary to resort logically to the use of semen from a donor, either for an artificial insemination or an in vitro fertilization. In both situations, only one of the women of the couple would be intervening directly in the pregnancy process, unlike the ROPA method .
By this technique, one of the women of the couple undergoes a process of ovarian stimulation to provide the oocyte, which is fertilized with the semen of a donor, and through in vitro fertilization, the embryos resulting from fertilization are transferred to the uterus of the other woman, who is the one who finally gets pregnant. In this way, one contributes the genetic load (oocyte), and the other becomes pregnant , taking both an active role in the whole process.
Advantages and disadvantages of the ROPA method
The most active participation of the two women who form a couple is the main advantage of the ROPA method, in which the couple decides what kind of motherhood they want. The risks of the method are the same as in any in vitro fertilization process. The woman whose ovaries are stimulated could suffer an ovarian hyperstimulation syndrome, although thanks to the current stimulation protocols, the risk is minimal .
Another risk is the multiple pregnancy associated with the intrauterine transfer of more than one embryo, as well as legal considerations, such as that the ROPA method is not legal in all countries.
