Egg sharing is an arrangement in which a patient undergoing IVF agrees to donate a portion of the eggs collected during their cycle to another patient — typically someone who cannot produce their own eggs. In return, the egg sharer receives IVF treatment at significantly reduced cost, or sometimes free of charge.
For patients who cannot afford standard IVF fees, egg sharing is one of the few routes to substantially reduced costs without travelling abroad. It is not right for everyone, but for those who meet the criteria and are comfortable with the arrangement, it can be a meaningful option.
How Egg Sharing Works
The process mirrors a standard IVF cycle for the egg sharer:
- Screening and eligibility assessment. The clinic assesses whether you are eligible to be an egg sharer — this involves physical health checks, fertility investigations, and genetic screening.
- Stimulation and egg collection. You undergo a normal stimulation cycle and egg collection, exactly as in standard IVF.
- Egg division. The collected eggs are divided between you and the recipient patient. The split is typically 50/50, though some clinics guarantee a minimum number for each party (e.g., at least 4 mature eggs each).
- Fertilisation and transfer. Your half of the eggs are fertilised with your partner's (or donor) sperm and proceeds as a normal IVF cycle. The recipient's half is fertilised with their partner's sperm.
- Reduced or waived treatment cost. In exchange for the donation, the clinic provides you with IVF treatment at reduced or no clinic fee. You typically still pay for medication.
Eligibility Criteria
Egg sharing eligibility criteria exist to protect both the sharer and the recipient. Most clinics require:
Age: Typically under 35, sometimes under 36. Egg recipients are specifically seeking younger eggs, so most schemes do not accept sharers above this threshold.
AMH and AFC: Adequate ovarian reserve is required — both to ensure the sharer is likely to produce enough eggs to split, and because the quality is a factor for the recipient. AMH is usually assessed as part of screening.
BMI: Most clinics apply BMI limits (typically 18.5–30) consistent with their standard IVF criteria.
Medical and genetic health: Carriers of serious genetic conditions are usually excluded. Full genetic screening (including cystic fibrosis, spinal muscular atrophy, and chromosome karyotyping) is typically required.
No previous live birth: Some clinics — though not all — restrict egg sharing to patients without a previous live birth, prioritising those for whom this is a first IVF attempt.
Cost: What You Actually Pay
The benefit varies by clinic but typically involves:
- Free scheme: Clinic fees waived entirely in exchange for egg sharing. You pay only for medication (£1,000–£2,000) and any additional tests.
- Reduced-fee scheme: Significant reduction on the standard cycle price — for example, £2,000–£3,000 instead of £5,000–£6,000 clinic fee.
The saving is real and substantial. However, you should compare what you are giving up (at minimum, half your collected eggs and therefore potentially some embryos) against the financial benefit.
What to Consider Before Agreeing to Egg Share
Your egg yield may be lower than expected. Stimulation response is not perfectly predictable. If collection produces only 6 eggs and the split gives you 3, your IVF cycle has a materially smaller embryo cohort than it would have with 6 eggs. Understand what the minimum guarantee is from your clinic and what happens if fewer than expected eggs are collected.
Donor-conceived children have rights. Under UK law (HFEA regulations), egg donors — including egg sharers — must be identifiable. Children conceived from your donated eggs can access your identifying information when they turn 18. This is not anonymous donation. Think carefully about how you feel about this.
Your own emotional response. Some egg sharers find it straightforward; others find it more complex than expected — particularly if their own cycle is unsuccessful but they know their donated eggs may have resulted in a pregnancy for the recipient. There is no right or wrong response, but it is worth thinking through before committing.
Confidentiality. You will not know the outcome for the recipient, and they will not know your outcome. HFEA rules govern what information is shared.
Finding Egg Sharing Schemes in the UK
Not all fertility clinics offer egg sharing — it requires a donor programme infrastructure and recipient patients. Large HFEA-licensed clinics, particularly those with active egg donor waitlists, are most likely to offer schemes.
Ask specifically when enquiring with clinics. Some advertise egg sharing openly; others arrange it on request for eligible patients.
Frequently Asked Questions
Q: If my egg sharing cycle fails, do I get another free/reduced cycle?
A: This depends entirely on the clinic's scheme terms. Some schemes cover one cycle only; others offer a second cycle if the first does not produce a usable embryo. Read the terms carefully before signing.
Q: Can I change my mind about egg sharing after I have started the cycle?
A: Under HFEA regulations, consent can be withdrawn at any time before the eggs are used — including after collection. However, withdrawing after collection may affect the financial terms of your agreement with the clinic. Check the contract carefully.
Q: What if I produce very few eggs and there aren't enough to share?
A: Most clinics have a minimum collection threshold below which the egg sharing arrangement is suspended — meaning you keep all your eggs and pay the standard (or reduced) fee. Understand what this threshold is before starting.
Q: Is egg sharing available on the NHS?
A: No. Egg sharing is a private arrangement between patients and clinics. NHS-funded IVF does not involve egg sharing.
Q: Can same-sex female couples or single women egg share?
A: Yes — egg sharing eligibility is based on medical criteria, not relationship status. Single women and same-sex couples who meet the medical criteria can access egg sharing schemes in the same way as heterosexual couples.
