ROPA method

Treatment targeted to female couples, where both play an active role in the gestation process.

Particularly indicated for couples that for personal or medical reasons, one of the members cannot undergo the complete process. Thus, while one of the females contributes the egg to obtain the embryo uniting it to a donor spermatozoid, the other will receive the embryo in her uterus to achieve the pregnancy.

Steps followed by the donor:

  1. Ovarian stimulation. This phase consists of drug administration so that the ovary produces more follicles than in a normal female cycle. The growth of these follicles is controlled with transvaginal ultrasounds every 2-3 days, depending on the individual needs of each patient .Once the follicles have an adequate size and the endometrium meets all the necessary requirements, the ovulation is triggered.
  2. Follicular puncture. It consists of the ultrasound-guided recovery of the oocytes developed in the ovaries to fertilize  them with the donor spermatozoa. When the puncture has been made, the endometrium preparation of the patient starts for the embryo reception.

  3. Laboratory. The egg and the spermatozoid union occurs here for the embryo creation. There are two types of techniques used:

    • Conventional IVF: it consists of depositing in the same culture both the egg and an adequate number of spermatozoa so that fertilization occurs in the same way as it would occur naturally.

    • ICSI: recommended for those cases with a low recovery number of oocytes. It consists of the direct introduction of one spermatozoid inside the egg, thus avoiding all the intermediate fertilization steps and making sure that the spermatozoid enters the egg.

When any of the two techniques above is performed, the embryo development is examined. Our objective is to achieve control at all times, through the “Time Lapse” technique, both of the culture conditions and of the minute by minute development of the embryos to keep this material in video for the future mothers.

Steps followed by the receiver:

The purpose of this process is to prepare the uterus to receive the embryos. Drugs are administered to prepare the endometrium for the embryo implantation. To ensure that the endometrium has the adequate characteristics, ultrasound tests are performed. Thus, when the necessary requirements are met and the follicular puncture of the donor has occurred, medication will be added vaginally to coordinate the endometrium with the embryo development stage.


This phase consists of depositing the embryos inside the maternal uterus. This procedure is performed in the operating room but is completely painless. Thus, anesthesia is not required. Besides, it is performed with the assistance of abdominal ultrasound control, so that the entire process can be followed visually. Using a cannula that does not affect the endometrium, the embryos are transferred in the uterine cavity 15 mm deep to provide higher success rates.

The remaining embryos obtained will be vitrified to offer new pregnancy possibilities without disrupting their quality.
