Egg donation

Egg donation is the process by which a woman donates eggs for assisted reproduction purposes. These oocytes are inseminated with sperm from a partner or a donor. Resulting embryos are transferred to the uterus of the recipient in order to achieve pregnancy. Oocyte donation is an altruistic and anonymous act that is considered in women when scientifically and clinically indicated. Donated oocytes can be: 
  • Oocytes received from a donor subject to an ovarian stimulation procedure simultaneos to the endometrial preparation of the recipient (fresh)
  • Frozen oocytes from a donor.

Egg donation: step by step


The receptor will undertake hormonal treatment in order to prepare her endometrium for embryo reception.

This treatment is tailored to each patient. It generally starts with a pituitary inhibition phase (induced by injectable medication) and the administration of oral oestrogen that will allow the endometrium to grow. Pituitary inhibition is not always required.

After approximately 10 to 14 days of endometrial preparation, an ultrasound scan will be performed in order to check its thickness is appropriate for embryo reception.

Once the endometrium is ready, the receptor should wait for her donor to finish the ovarian stimulation process or wait for embryo transfer to be scheduled when using vitrified donor eggs.

After obtaining the gametes, an IVF/ICSI is performed in the laboratory.

The day after this procedure the number of fertilized oocytes or pre-embryos is determined. These will be kept in the laboratory for a period of 2-6 days after which we will proceed to embryo transfer.

The embryo(s) with better morphological characteristics is introduced into the uterus via a thin catheter. It is a short and quick process, which does not cause discomfort and does not require anaesthesia or sedation. The number of embryos transferred will depend on the clinical history of the patient or partner, with no more than 2 embryos recommended per cycle. Patients are fully assessed regarding this, and will receive the necessary information from their doctor in order to obtain a successful pregnancy while avoiding the risks of multiple pregnancies.

A pregnancy blood test is performed 12 days after the embryo transfer. An ultrasound scan is scheduled 2 weeks after a positive result to confirm a pregnancy is in progress.

The most common reasons for chosing egg donation are:
  • Primary ovarian failure or secondary due to surgery, chemotherapy and radiotherapy.
  • Gamete genetic alterations.
  • Serious hereditary and maternal genetic diseases.
  • Repeated failure of assisted reproduction techniques due to insufficient response to ovarian stimulation.
  • Repeated failure of embryo implantation.

  • Fixed Price: This is a fixed priced treatment that includes the services detailed on the cost breakdown. Supplementary tests may be required according to medical criteria, however, these will be notified in advance.
  • Validity: The validity of this estimate is 6 months from the date of your first consultation.
  • Medication: Medication costs are not included. These will be assumed by the patient.
  • Embryo devitrification: when an embryo transfer fails, an additional cost of 1.860 € will apply to subsecuent attempts.
  • Cancellation by the patient: In case of cancellation of the treatment, the patient must pay the costs incurred until that point.
  • After 2 years of embryo cryopreservation: It will be your decision to either chose from one the authorised applications regarding embryo donation/destruction or the payment of a 435€ fee per year of conservation for future use.
  • Sperm preservation: this has a cost of 250€, and 230€ per year of conservation.
  • A minimum of 8 mature donor oocytes is guaranteed.
  • We guarantee at least 2 blastocyst-stage embryos. In the event of this not happening or when there is only one embryo and the patient does not achieve a pregnancy or has a miscarriage, the patient will only have to pay for the embryo transfer in a subsequent treatment; the remaining costs will be covered by the clinic (this warranty does not apply in case of male factor infertility).
