ROPA Method

ROPA Method

The ROPA method is aimed at female couples so that both are able to participate biologically in the pregnancy and experience shared motherhood.

ROPA stands for Reception of Oocytes from the Partner, a medical reproductive procedure carried out in Spain for the last 10 years. An increasing number of female couples are using this assisted reproduction technique in order to become mothers.

The ROPA method technique is the same as in vitro fertilisation with egg donation, but the difference is that the donor is not anonymous, it is the future mother. The procedure is quick and only takes 15 days to complete.

Steps to follow:

  • Ovarian Stimulation. The genetic mother undergoes a maturation process for various eggs in a cycle to increase the number of resulting embryos and chance of success.
    Endometrial preparation. Ovarian stimulation is carried out in parallel in the gestational mother, through a pharmacological treatment that promotes growth of the endometrium preparing it to receive the embryo.
  • Egg Fertilisation. This is carried out with semen from an anonymous donor, as set out by Spanish legislation. We look for similar physical characteristics to those of the gestational mother: skin, hair and eye colour etc. as well as the same or a compatible blood group.
  • Monitoring the embryos. Our embryologists monitor the development of the embryos that are deposited in time lapse incubators so you are able to see their development and select those with the highest implantation ability when transferred to the gestational mother.
  • Confirmation of pregnancy. 15 days after the transfer, a pregnancy test is taken to check if gestation has occurred.


The success rate for this method is one of the highest for assisted reproduction treatments, ranging between 65 and 70%. However, the success of the pregnancy is closely linked to age and the ovarian reserve of the woman donating the egg. Another important factor to take into account is the condition of the gestational mother’s uterus; any pathologies may reduce the probability of pregnancy.
