Egg donation is the process whereby a woman uses the eggs from a donor in order to have their own child. The donor’s eggs are fertilised with sperm, usually from the woman’s partner, to produce embryos. These are then transferred into the womb, making pregnancy possible.
There are three ways to access egg donor treatment at IVI: using a known donor, a UK donor or using the IVI overseas egg donation programme.
In 26 years, the IVI Group has helped more than 160,000 dreams come true.
97% of our patients said they would recommend IVI. We work with you at every stage of the treatment, providing support and care.
IVI has a worldwide reputation for innovative research and has developed and patented pioneering techniques and technologies.
IVI is one of the largest fertility providers in the world, with over 70 clinics in 13 countries.
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:
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.
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.
Before receiving the embryos, patients undergo treatment to prepare the endometrium for embryo transfer.
Women are given medication to take to prepare the uterus for implantation of the transferred embryo.
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.
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.
