ropa method

The ROPA method, or Partner Oocyte Reception, is a reproductive option for same-sex couples of women who wish to actively participate in fertility treatment. Each mother has an important role in fertilization.

One of them undergoes ovarian stimulation to transfer her eggs, this mother will be the genetic mother. The other one will be the gestating mother. Since once the eggs are fertilized with anonymous donor sperm, the best quality one will be transferred to her uterus to nest, produce the pregnancy and give birth to the baby.

In order to obtain the best results, it shall be your fertility specialist who, thanks to each patient’s personal evaluation and the correct diagnosis, will advise and accompany you in choosing the right treatment for you.


The anonymity of the donors

Another important aspect of this treatment is the anonymity of the donors. In our country, the Assisted Reproduction Law guarantees that the identity of the man or woman who, altruistically and in solidarity, decides to donate their gametes so that our patients can have their baby will not be known.

We give great importance to the study and preparation of each patient’s endometrium. With these guidelines we have demonstrated that finding out what the best moment to transfer the best embryo is allows us to increase the chances of achieving pregnancy. In our fertility treatments we try to get as close as possible to the natural steps of human reproduction, but optimizing each process to enhance the result.

For whom is the ROPA method indicated?

The ROPA method is recommended for same-sex couples. One of them must have a good ovarian reserve to be the “donor” patient, and the other woman must have an adequate uterus for embryo implantation.

This technique is recommended for:

How is the ROPA method process?

The following is a step-by-step description of the ROPA method:

1. First visit to evaluate your case and design the best plan

We adapt to your availability and organize all steps of your treatment

2. Selection of the mom who will donate the egg

This is one of the most important moments for patients. At Vida, we always do our best to respect the wishes of the expectant moms. We will manage your expectations with sincerity and empathy. Our interest is to achieve pregnancy as soon as possible.

3. Synchronization of the two moms

In order to be able to offer a treatment with fresh embryo transfer, it is important to synchronize both cycles. For this reason, both the mother who will donate the egg and the mother who will gestate the embryo will have to undergo a period of contraceptives to control their cycle and be able to start the next cycle synchronized and in parallel.

4. Double preparation

In the next period, the patients will start their treatment in parallel. The genetic mother will undergo ovarian stimulation in order to obtain a good number of oocytes, and the gestating mom will begin the preparation of her endometrium for embryo implantation to take place. This stage usually lasts between 10 and 15 days.

5. Ovarian puncture

The mother who will yield the eggs to conceive her baby must undergo an ovarian puncture after the stimulation period. It is a simple and quick procedure (about 15 minutes) that is performed under light sedation to avoid any discomfort. During the puncture we extract, through a slight aspiration, the follicular fluid containing your follicles where the oocytes that have developed during that cycle are located. It is performed by transvaginal ultrasound and does not require hospitalization, so recovery is quick and you can resume your normal life.

6. Fertilization and embryo development

The mature oocytes obtained are fertilized in the laboratory (with donor sperm) to generate embryos. As a rule, fertilization is performed with the ICSI sperm microinjection technique to increase fertilization rates. The embryos obtained are kept under observation in the laboratory incubators until they reach the blastocyst stage (day 5 or 6 of embryonic development).

7. Embryo transfer

Embryo transfer is preferably performed on the 5th day of embryo development, thus increasing implantation rates. It is a simple procedure, which does not require anesthesia, and which consists of depositing the embryo in the uterus of the mother who will gestate and give birth to the baby. Embryo selection follows very strict quality criteria in order to achieve pregnancy in the fewest number of attempts possible.

8. Beta wait

After the transfer, you will be able to continue with your normal life following our recommendations in some daily aspects. You will know the result of the treatment after approximately two weeks of waiting.
