Egg sharing

Egg sharing allows patients who have a normal ovarian reserve (see A-Z of Fertility) to have IVF/ICSI treatment, and in the process donate some of their eggs to someone who doesn’t produce good quality eggs of their own. If you choose to share your eggs, you’re choosing to donate some of your eggs to another woman. You receive your own treatment at a discount and are helping someone else achieve their dream of starting or growing their family.

Types of egg sharer

There are two types of egg sharer:

  • Altruistic egg sharers (who give some of their eggs to someone they don’t know)
  • Known egg sharers (who give some of their eggs to someone they know needs them in a cycle of their own)

Who can be an egg-sharing donor at Nurture Fertility?

To be an egg-sharing donor at Nurture Fertility, you must:

  • be less than 35 years of age (i.e. treatment cycle must finish before the 35th birthday)
  • have an AMH value of at least ≥15.0 pmol/L (showing a good ovarian reserve)
  • have body mass index of less than 30
  • be a non-smoker
  • test negative for various infectious diseases and have a normal genetic analysis
  • have an approved medical and family history

Specific requirements for egg-sharing donors

The aim is to donate a minimum of 4 eggs to the person receiving your eggs. The recipient can receive your eggs  fresh (when her menstrual cycle has been coordinated with your treatment cycle). The eggs are shared between you (the egg-sharing donor) and the recipient. The number you each receive depends on how many eggs are available.

Your commitment as an egg sharer

As the egg-sharing donor – whether you know the recipient or you are donating altruistically – you make a formal commitment to share a number of your eggs, depending on how many we collect. If you decide to keep all your eggs, you are liable for the full treatment costs of a standard cycle.

NB. Both you and the recipient should be aware that you as the donor are free to withdraw consent to donate your eggs, or to transfer embryos derived from those eggs, at any time up until they are transferred to the recipient.

How the eggs are shared

It’s our policy to try to ensure that your chances of pregnancy are not reduced by donating some of your eggs. As long as the egg-sharing donor retains at least 3 eggs for her own use, our data shows that the donor has no reduction in her expected chances of pregnancy in her fresh treatment cycle.

What if, as an egg-sharing donor, I don’t produce at least 8 eggs?

If less than 8 eggs are collected, there are a few options available to you.

  • Donate all your eggs:
    You’ll be offered a new treatment cycle, free of charge except for the stimulation drugs, which you’ll pay for

    • New cycle scenario 1:
      If you produce 8 or more eggs in this new cycle, they’ll be shared between you and the recipient, and the number you have will depend on how many are available
    • New cycle scenario 2:
      If you produce 8 or more eggs in the new cycle and decide to keep all of them, you will have to pay for the rest of your treatment
    • New cycle scenario 3:
      If you produce less than 8 eggs in the new cycle, you can keep them all, and pay to continue with rest of your treatment if you wish. We would advise against further treatment as an egg sharer
  • Keep all your eggs:
    Nurture Fertility will let the recipient know that the donation isn’t going ahead. You proceed with your own treatment, and pay the full balance before embryo transfer takes place

NB. If the clinical team decide that your ovaries are not responding adequately during stimulation monitoring, and not enough follicles are developing, we’ll cancel the stimulation cycle. This is unless you want to continue with treatment for yourself without attempting to share eggs, in which case you’ll pay for all treatment and drug costs, as in a standard IVF cycle.


You need to undergo some screening tests to make sure there’s no reason why you can’t be an egg sharing donor. You can learn more about the types of test on the Fertility Assessment page, or call the clinic for more information.
