Reciprocal IVF or ROPA Method

How it works

After a period of ovarian stimulation and through follicular aspiration, the oocytes are retrieved from the couple's donor woman, synchronizing the recipient's endometrium simultaneously. This process is carried out under ultrasound monitoring by the gynecologist who determines the best time, just before ovulation. 

A sperm sample compatible with the recipient's blood group and phenotype is obtained from our bank. Sperm samples are obtained from anonymous donors who are healthy men subjected to strict clinical, chromosomal and psychological screening, ensuring that they do not carry any detectable disease according to the current assisted reproduction law. 

Good-quality motile spermatozoon is selected one by one.Afterwards it's directly injected into each egg after immobilization through microinjection (ICSI). Intracytoplasmic sperm injection (ICSI) is carried out in the laboratory and subsequent incubation and monitoring is performed to check that the egg/s have been fertilized correctly, producing developing embryos.

The obtained embryo is transferred into the woman's womb through a painless process where usually there is no need for sedation, and after which rest is recomended. The gynecologist introduces the embryo using a soft catheter under ultrasound guidance.

From 10-12 days after the embryo transfer, a blood test can be performed to identify the presence of the Beta-CGH subunit, confirming the diagnosis of pregnancy.

If there are any oocytes that have been retrieved but not been used for the process, they can be preserved using vitrification if desired. Vitrification procedure allows oocyte preservation and long term storage in custody.

If there are any surplus embryos they can be cryopreserved for own use or donation, under a strict legal protocol that all clinics are required to obey. Embryo cryopreservation is performed by vitrification and they remain in custody.
