  • 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 sperm
  • 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


In 26 years, the IVI Group has helped more than 125,000 dreams come true.


IVI has a worldwide reputation for innovative research and has developed and patented pioneering techniques and technologies.


97% of our patients said they would recommend IVI. We work with you at every stage of the treatment, providing support and care.


IVI is one of the largest fertility providers in the world, with over 70 clinics in 13 countries.

Egg Donor

Egg Donors

You may require egg donation as part of your fertility treatment. This may be because of medical complications or the female partner’s maternal age. There are three ways to access this treatment at IVI:

Using a known donor

A patient may choose to use an oocyte donated from a relative or another known person. These eggs would undergo medical screening as part of the process and counselling would be necessary.

Using a UK donor

Patients can use a UK donor. Due to the current UK law, at the age of 16 the child (or parent on their behalf) can access the donor’s non-identifiable information. When the child reaches 18 they may contact the donor if they wish, but this doesn’t change the legal status of the donor.

Using a donor from IVI in Spain

IVI have a network of clinics across Spain that for many years have been working with UK patients who require egg donation. Egg donation is anonymous 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.

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 semen

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

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

Egg donation

Fertilisation and transfer

The sperm and eggs are brought together using in vitro fertilisation (IVF) or sperm microinjection(ICSI). Once the eggs have been fertilised, they are kept in the IVF laboratory until everything is ready for transfer into the woman’s uterus.

Embryos are selected for transfer and the ideal moment for treatment is identified. The medical team assess these factors based on the couple’s medical history, the number of embryos obtained, their characteristics, and the individual circumstances of the treatment cycle.
