Types of egg donation treatment available at IVI

Using a known donor

You may choose to use eggs donated by a relative or another known person. The donor would undergo medical screening as part of the process and counselling would be necessary.

Using an IVI donor

IVI offer 2 types of donor source; both use non-identifying information such as height, ethnicity, hair and eye colour to provide the best possible match to the individual or couple.

UK Donor

IVI can source a UK donor, and the whole process will take place in one of IVI’s UK clinics. IVI UK currently partners with Altrui who support IVI patients in matching recipients to egg donors, providing one donor to one recipient policy. This guarantees that the donor will donate her eggs exclusively to you.

Children born as a result of egg or sperm donation in the UK have the right to access identifiable information about their donor once they reach 18 years of age. An egg donor’s details will be kept on the HFEA Register, where they are carefully protected and are not available to the general public. Donors have no legal rights to children born as a result of their donation.

Donor from IVI in Spain

IVI in Spain has the largest frozen egg bank in the world. We, therefore, have access to egg donors with all characteristics, with no waiting list.

  • Primary ovarian failure is when menstruation does not begin during puberty (gonadal dysgenesis – Turner syndrome or Swyer syndrome; and pure gonadal dysgenesis – Savage syndrome or resistant ovary syndrome)
  • Premature ovarian failure is when ovarian function stops before the age of 40, with periods starting to become irregular and eventually stopping altogether.Some of the causes of this include:
  1. Hereditary factors: carriers of Fragile X Syndrome, etc
  2. Enzyme alterations: galactosemia, 17a-hydroxylase deficiency or gonadotropin secretion defect
  3. Autoimmune disorders: MEN (multiple endocrine neoplasia) syndrome, Addison’s syndrome, diabetes mellitus, hypothyroidism, anti-ovarian antibodies, etc
  4. Infectious factors: parotiditis, rubella, etc
  5. Environmental factors: smoking, etc
  6. Surgical castration: due to cysts or tumours on the ovaries
  7. Past treatment with chemotherapy or radiotherapy


  • Repeated failure with IVF is when women do not respond to ovarian stimulation; when several attempts at fertilisation using ICSI are not successful; or when embryos repeatedly fail to implant successfully.

Recommended for:

  • Men who have no spermatozoa
  • Men who are carriers of certain genetic diseases or of sexually transmitted infections
  • Men whose semen has chromosomal abnormalities
  • Women who do not have a male partner

The Procedure

Before receiving the embryos, patients undergo treatment to prepare the endometrium for embryo transfer.

Egg donation


Women are given medication to take to prepare the uterus for implantation of the transferred embryo.

Egg donation

Preparation of the sperm

The sperm is prepared in the laboratory to select the most suitable spermatozoa for fertilising the donated eggs.

Sperm can also be cryopreserved (frozen) in advance and used when compatible eggs are available.

Egg donation

Fertilisation and transfer

The eggs are fertilised with sperm either using conventional in vitro fertilisation (IVF) or sperm microinjection(ICSI). Once the eggs have been fertilised, they are kept in an incubator until the embryo is ready for transfer into the woman’s uterus.

The scientific staff together with the medical team will select the embryo to transfer to maximise the chances of pregnancy occurring.
