ROPA Method or Shared Motherhood
The ROPA method is a treatment aimed at same-sex couples who wish to take both an active part in their fertility treatment.
Each mother will play an important role in the treatment.
One of them will undergo an ovarian stimulation to donate her eggs; this mother will be the biological mother. And the other mother will be the one who will carry the child. Once her partner’s eggs have been fertilised with anonymous donor sperm, the best embryo will be transferred to her uterus for its implantation and future pregnancy.
To achieve the best results, your fertility specialist will need to advise and support you in choosing the treatment best suited to your case, based on a personal assessment of each patient and a proper diagnosis.
Who is ROPA Method for?
The ROPA method is recommended for lesbian couples. One of women must have a good ovarian reserve to be the “donor” patient, and the other woman must have an adequate uterus for embryo implantation.


ROPA Method: Sperm donor selection
Another important aspect of this treatment is the anonymity of the donors.
In Spain, the Assisted Reproduction Law guarantees that the identity of the men or women who decide to donate their gametes so that our patients can have their baby will remain anonymous.
The donor for each couple will be selected by our medical team on the basis of their fertility potential (sperm quality) and the phenotypic characteristics of the patients.
ROPA Method Process
Donor/Recipient Selection
This is one of the most important moments for women who want to undergo a ROPA Method treatment. At Vida Fertility, we always do our best to respect your wishes. We will manage your expectations with sincerity and empathy. Our interest is to achieve pregnancy as soon as possible.
This decision will be made durring the first consultation (online or at the clinic). The Docteur will study both your medical histories, assess your case and establish a personalised treatment plan. Your personal assistant will then send/give you all the documents you need to make your decision and start your treatment from home.
Synchronisation of the two moms
In order to offer a treatment with a fresh embryo transfer, both cycles need to be synchronised. Thus, both mothers (donor and recipient) will need to take the contraceptive pill for a little while to control and synchronise their cycles.
Double preparation
In the next period, the patients will start their treatment in parallel. The genetic mother will undergo an ovarian stimulation in order to obtain a good number of oocytes, and the mother who will carry the baby will begin her endometrial preparation to be ready for the embryo implantation. This step usually lasts between 10 to 15 days.
Egg retrieval
The mother who will donate her eggs to conceive their baby must undergo an ovarian puncture or egg retrieval at the en of the ovarian stimulation. This is a quick and simple procedure (about 20 minutes), performed under light sedation. During the puncture, we aspirate all the liquid from the follicles and recover the oocytes. The puncture is performed vaginally and does not require hospitalisation. The recovery is rapid.
Fertilisation and embryo development
The mature oocytes obtained during the puncture are fertilised in the laboratory (with donor sperm) to generate embryos. As a general rule, fertilisation is performed using the ICSI technique of sperm microinjection to increase the fertilisation rate. The embryos obtained are kept under observation in the laboratory incubators until they reach the blastocyst stage (day 5 or 6 of embryonic development).
Embryo transfer
The embryo transfer is a simple procedure where the selected day-5 embryo is placed in the patient’s uterus, without the need for any type of anesthesia. The embryo selection follows very strict quality criteria in order to achieve an ongoing pregnancy.
