Identifiable Egg Donation

Identifiable Egg Donation allows the donor to be identifiable. With Egg Doantion Select programmes, your child will not be able to identify the egg donor in the future. With Identifiable Egg Donation, any child/children resulting from this programme who wish to know more about their donor may do so, when they are aged 18 or older.

All treatment is confidential between both parties. The Identifiable Egg Donation Programme provides you with extended donor profiles for the selected donor, with childhood photo - eye colour, hair colour, height etc. The donor is identifiable, which means that a child/children resulting from this treatment who wish to know more about their donor may contact Sims IVF, in writing once they are aged 18 or older.


When you come for a consultation at Sims IVF, our aim is to help you to conceive and experience the joy of having a family.   Your Sims IVF consultant will discuss the various fertility treatment options with you.  
Egg Donation may be one of those options and this depends on your:
  • AMH levels
  • Previous fertility treatment
  • Medical history.
When recommending egg donation as an option, your Sims IVF consultant will brief you on:
  • The egg donation programme options available
  • Risks associated with egg donation
  • Risks associated with fertility treatment
If you decide to proceed to the next stage, your doctor will refer you to one of our qualified Egg Donation Co-ordinators.
Consulting with your Egg Donation Co-ordinator
Our Egg Donation Co-coordinators are nurses with specialist expertise in egg donation.  Your Egg Donation Nurse Co-coordinator guides you through the programme with as much care and support as possible.  
  • They explain the programme
  • Answer your questions
  • Provide treatment time-frames
  • Take you through the process step-by-step
  • Ensure that you are confident in your decision and fully prepared to proceed.
Our Sims IVF Egg Donation Co-ordinators have a particularly sensitive and empathetic approach to their work. Entirely dedicated to our egg donation programmes, our co-coordinators will be your link to Sims, and will do everything in their power to care for you and ensure that you are supported and informed throughout the process.  

Consent Forms
Consent Forms are part of your consultation process
Before you commence treatment at Sims IVF, both you and your partner must sign an Egg Donation Consent Form.  
The Egg Donation Consent Forms are given to you by your Egg Donation Co-ordinator. You will have time to read and study the form during your investigations and you will get the opportunity to discuss your concerns.
Consents highlight and invite you to consider all potential outcomes and complications. Your Egg Donation Co-ordinator talks you through the forms, and provides you with a copy to bring home as the consent requires both time and consideration. 
The areas covered in the Consent Forms include:
  • Investigation plan (DNA and SA Freeze)
  • Screening (EU Cell and Tissue Directive)
  • Mandatory Counselling
  • Timeframe of your treatment plan
  • Egg Donation programme cost options
  • Paying for your programme
  • Possible surplus embryo freezing
  • Donor profiles
  • Donor selection
  • Risks associated with egg donation including: shipping, cross infection
  • Anonymity – currently protected by law
  • Risks of failure
  • Risks to the child – hereditary diseases
  • Multiple births
Once you understand the process, the risks and the options available to you, you can sign the Consent forms.
You must return the signed copy to Sims prior to beginning any treatment.


There are some standard tests that are performed for each recipient couple. Once you’ve had your consult with your Nurse Co-ordinator the next step is scheduling these tests.

Bloods and reproductive immunology screening

At the outset, we take a blood sample from both you and your partner.  Naturally, it is important to test for rubella immunity, hormone levels, and what we call infectious screening. Infectious screening will include tests for HIV, VDRL and Hepatitis B and C and HTLV 1&2.

Semen analysis

We provide a comprehensive semen analysis service at Sims IVF to ensure that the best possible sperm sample is used in your cycle, maximising your chances of success. If you have already has a semen analysis at Sims within the past year you will not be required to repeat this stage.

Saline Infusion Sonography and trial stimulation to assess womb lining

A standard test called a saline sonography will be conducted. It’s performed to assess two major factors of success in treatment; the ease of transfer and how normal the inside the womb is. Doing a mock transfer beforehand ensures (i) the embryos can be out in as gently as possible and into the correct location in the uterus. Finally, at the same time a mock transfer (ii) checks that the inside of the womb is normal and that there are no fibroids or polyps which might reduce the chance of an individual embryo implanting and reducing the success of pregnancy. If you have already had an SIS at Sims within the last 12 months then you will not be required to repeat this test.  

Implications Counselling

Implications counselling is a mandatory legal requirement for all couples wishing to avail of egg donation. You will also find that counselling for both of you is critical at this stage, before the treatment cycle actually begins,  as it helps you to deal with the various questions and concerns that come up for you, some of which you may not have considered before.

Sims IVF provides resident counsellors who are familiar with the complex issues involved in engaging in the egg donation programme.  They are conscious of the various nature of the procedure and the implications of a treatment that is relatively unconventional.  They can help you to deal with emotional issues and concerns that will inevitably arise.

The results of these test and investigations will be reviewed by your egg donation coordinator and your doctor. Subject to the results you will be signed off to proceed with the next stage.

Sperm Freeze & Consents Appointment

Consents: At this appointment you will meet with a trained donor coordinator who will go through the consent forms with you that you will have already studied and partially signed. Our nurse will highlight the main risks associated with the programme in addition to them being described in the consent. You will have an opportunity to ask questions and once you are happy to proceed and sign off on the consent form your semen freeze procedure may take place.  

Semen Freeze

A semen freeze should be carried out following 2-3 days of abstinence from intercourse or masturbation. Shorter or longer periods of abstinence will impede optimum results and so you should stick to our recommendation. Sperm samples are analysed before they are frozen in addition to a test thaw procedure prior to shipment to ensure the sperm thaws normally. Usually only one semen sample is required to be frozen but this does depend on the sperm quality and you will be advised by the embryologists if a subsequent sample is required.

Frozen sperm transported to our partner clinic

The sperm travels out in a special vessel which ensures it is maintained at the appropriate conditions. We understand the importance of this part of the programme and that it proceeds without any risk to the samples and as such work with specialty couriers with experience transporting these important samples. As such, your samples are accompanied at all times until they are delivered safely to the laboratory staff at our partner clinics.

Donor Selection

This is an exciting phase in the process. As soon as investigations are complete and the sperm has been frozen, the donor allocation process begins.

You will be given a username and password unique to you so that you can log on in the privacy of your own home and review the options available to you. Typically there are approximately 15 donors available to choose from although these can sometimes be more. You are allocated a specific time period on the portal whereby no other couples will be online looking at the donors you are considering. When you have made your decision, you will make your choice and we will contact our partner clinic to inform them.

When you are looking at the donors you will be able to filter the available donors by hair colour, eye colour and blood group which may help you narrow your decision. You can see completed profile of the donor and a sample is shown below.

Once you have approved the donor, work with our partner clinic will commence.

Donor Cycle, Fertilisation, Freeze

The donors cycle is planned using medications so that we know approximately what date her egg collection will take place and when the shipment of embryos back to Sims will take place so that we can work with you to plan your treatment.

Egg Retrieval

Eggs are retrieved from a donor by means of vaginal ultrasound guided aspiration of ovarian follicles.  This involves the introduction of a specially designed needle through the vaginal wall under local anaesthesia and intravenous sedation.

There is a small possibility that the donor may not respond to her treatment and therefore no eggs become available. Thankfully this happens rarely but if no eggs are available, the hormones are stopped and another donor is found as soon as possible.

Fertilised eggs will be grown to blastocyst stage (Day 5) and frozen before being shipped with a specialist courier back to Sims.

Embryo Transfer

After fertilisation, you are informed of arrangements for embryo transfer.  Once the fertilised embryos are confirmed, preparation of the female recipient begins. This is organised by your co-ordinator. A month long treatment schedule is set up and a prescription for special medication is given to the woman to help prepare her womb.

We want to ensure that the embryos are placed in the womb at the optimal time for implantation. This is achieved initially by starting on the contraceptive pill for a short period. Then a nasal spray is used to make the ovaries inactive. This is known as down regulation. Some women requiring donor eggs do not menstruate and therefore may not need the spray. Once down regulation has been achieved, hormone tablets are taken daily to prepare the lining of the womb to receive the embryos.

Ultrasound scans are carried out following commencement of the hormone tablets so that the doctor can assess your womb lining to ensure that it is the right thickness for embryo transfer. If the womb lining is satisfactory, an additional hormone – Progesterone – is taken as advised. This ensures that the lining of your womb is in the best possible condition for implantation of the embryos.

The blastocyst embryos are thawed on the morning of transfer in preparation for transfer into the uterus. They are replaced through the neck of the womb using a small plastic tube. This is usually a painless procedure rather like having a cervical smear test and it takes 5-10 minutes to perform. Normally we will transfer up to two blastocysts. If you are fortunate enough to have more than two blastocysts, then we will freeze these for future use.

Following embryo transfer, the hormone tablets and Progesterone medication are continued daily as indicated in your treatment schedule. These hormones reflect the changes that normally occur in a woman’s body at this time. While the hormone supplements are being given, a period will not usually occur, but this does not necessarily mean pregnancy has begun. 12 days after the embryo transfer, a blood test is carried out to establish whether you are pregnant. If this is positive, a scan is performed three weeks later to ensure that the pregnancy is inside the womb and that a foetal heartbeat can be seen. Hormone supplements continue until at least week 12 of pregnancy.

N.B. Your first embryo transfer is included in the all inclusive package price. Subsequent transfers will be charged as frozen embryo transfer cycles.


You will be asked to perform a urine pregnancy test at home on a specific date, 12 days after your blastocyst transfer. We recommend you use either Clear Blue or First Response testing kits as they are capable of detecting early pregnancies.

Pregnant: If your home pregnancy test is positive you will be asked to attend the clinic for a confirmatory blood test that lets us know how pregnant you are. Depending on the result you may be asked to come back and repeat this test a few days later. When the positive result has been confirmed your co-ordinator will advise you about your medication and early pregnancy care, and will book you in for your first obstetric scan at six weeks. Your co-ordinator will offer guidance and support throughout the first 12 weeks of pregnancy until your care is referred to an obstetrician.

Not Pregnant: Although our pregnancy rate is high there is no guarantees of a positive outcome. If the results of your home pregnancy test is negative your co-ordinator will offer you the option of a confirmatory blood test so that you can be sure of the result
