What is it?

Egg donation is a reproduction assisted technique that uses eggs originating from a meticulous egg donation program. The donated eggs are fertilised by the couple´s semen or by donated semen when necessary.

Who is it recommended for?

This treatment is recommended for those patients whose problem with fertility is derived principally from an oocyte factor. Either their ovaries are unable to produce enough oocytes or the quality of these oocytes are not optimal. This treatment is also recommended for patients that have or are able to transmit a hereditary disease.

  2. Egg donation program

    The selection of the ideal donor is selected based on the similarities in phenotype between the donor and the patient.

  3. Egg Transfer
    The day of the transfer, after having consulted with your gynecologist and embryologist, you will decide the number of embryos to be transferred. This of course depends on the quality and development of the embryos. According to Spanish law, the maximum number of embryos transferrable is three. This number is set to try to avoid multiple gestations. The egg transfer is done in the surgery suite but you will not need any type of anesthesia. The embryos are transported from our laboratory to the surgery suite in the most optimal conditions. The embryos are then introduced into the uterus through a catheter by the gynecologist. The patient can be accompanied by whomever they wish in the surgery suite.
  4. Cryopreservation of embryos

    In the event that the patient should have embryos left after the embryo transfer, they would be vitrified and preserved in our bank with prior consent from our patients. These embryos can be used in future cycles if that is what the patient decides. This can be due to a failed first try or because our patients desire another pregnancy. The cycle used when there are cryopreserved embryos is called (Frozen embryo transfer) and it is evidently a much simpler cycle as far as patient preparation is concerned. This is due to the fact that the patient does not have to undergo preparation for an egg retrieval procedure.
