ROPA Method

What is it?

Madres-FIV Marbella

The ROPA method allows a couple of women to get involved and share motherhood. With this technique, one of them donates the ovule and the other one breeds the embryo, being both mothers of the baby.

How are we going to do it?

The process to perform the ROPA method consists of several parts:

First, once we have decided on the role that each one will have, the donor mother will undergo an ovarian stimulation treatment to encourage the development of several ovarian follicles (the sacs that contain the oocytes). In this way, we will get a sufficient number of eggs to fertilize and obtain high quality embryos.

Upon completion of the stimulation, the oocytes will be extracted by follicular puncture and fertilized in the laboratory, using donor semen.

All FIV Marbella donors undergo strict analyses and exams to ensure their physical and psychological health. Donor selection will be made according to the phenotypic characteristics of the recipient couple.

In coordination with the embryo culture in the laboratory, the recipient will receive an endometrial preparation treatment, with which we will prepare her uterus to receive the embryo. The embryo transfer will be scheduled coinciding with the end of this process. It is a simple and painless process that does not require anaesthesia.

After about ten or twelve days, we will analyse the presence in the blood of the beta-hCG hormone, which will confirm that the treatment has been successful.

How to decide?

The decision on what role each one will have to be taken within the couple. However, the doctor who takes your case can advise you in this regard, based on clinical criteria and preliminary tests performed. The goal will always be to maximize the chances that the treatment will succeed.


  • In case of wanting a second pregnancy with frozen embryos from a previous ROPA treatment, should the pregnant mother be the same as in the first transfer?

In the case of the ROPA treatment, the embryos are from the couple, so the embryos can be transferred to either mother as long as they do not present counterindications for a pregnancy.

  • What does Spanish Law say about maternity in lesbian couples? What legal requirements does the ROPA treatment have?

When a lesbian couple has an assisted reproduction treatment and has a child, both will be legally recognized as mothers as long as they are married. In the case of unmarried couples or unmarried partners, at the present time only the one who gives birth to the child may be registered as a mother, and the non-pregnant mother must go through an adoption process to be legally registered as a mother.In the case of wanting to go through a ROPA treatment, marriage between both women is mandatory.

Check our rates

he success rates shown correspond to those of our headquarters in Marbella. The percentages presented in this section have been divided as follows:

eta-hCG positive: hormone produced by the body once the embryo is implanted in the uterus. Calculated after 10/12 days after embryo transfer.

Clinical Pregnancy: Calculated in the 4 week gestation by means of ultrasound. Its presence is a sign of implantation of the embryo in the endometrium.
