What is the difference between the ROPA method and donor IUI?

By Marta Barranquero Gómez B.Sc., M.Sc. (embryologist).
Last Update: 08/11/2022

The fundamental difference between these two assisted reproduction techniques lies in the participation of the pregnancy. In the case of the ROPA method, both women participate in the process. One woman of the couple provides the eggs that will be fertilized with the donor sperm, while the other woman will be in charge of carrying the pregnancy to term.

In contrast, in artificial insemination with donor sperm (Donor IUI) only one woman participates, who is administered hormonal medication to stimulate the ovary and produce 1-2 follicles.
