Using Your Frozen Eggs Without a Partner

Building a family on your own terms: what to consider, what's possible, and what UK law says

Many women freeze their eggs because the right relationship hasn't happened yet. According to the Nuffield Council on Bioethics, most UK women who undergo elective egg freezing are single, university-educated, and in professional employment, and not having a committed partner is a common reason for freezing eggs.

If that's you and you're now thinking about whether to use your eggs without waiting for a partner you are absolutely not alone. In 2023, 3,693 single patients had IVF in the UK, an 83% increase since 2019 and the fastest-growing patient group, according to the HFEA's Fertility Treatment 2023: trends and figures report. Many of those women move forward as solo mothers by choice, with donor sperm.

We'll walk through how IVF with donor sperm works in the UK, what UK law actually says, how to choose a donor, the emotional and practical realities, and the support that exists for women who go this route.  It is important to note that not all countries allow for IVF for single women and not all allow for gamete donation so it is important to check the local laws in the country you plan to use your eggs. 

A short note on language

In this article we use “solo mother by choice” — the term most commonly used in the UK community — to describe a woman who decides to have a child on her own using donor sperm. None of these terms imply you're closing the door on partnership in the future. They simply describe how you started.

How IVF with donor sperm works in the UK

If you've already frozen your eggs, the process is essentially the same as any IVF cycle with frozen eggs, with one extra step: choosing and obtaining donor sperm.

In summary:

  • You select a donor — through a donor known to you,  through your clinic, a UK-licensed sperm bank or sometimes through an imported supply from a foreign sperm bank that's HFEA-compliant.

  • Your eggs are thawed — vitrified eggs are warmed in the lab. Around 70–85% typically survive, depending on age at freezing and clinic.

  • Surviving eggs are fertilised — almost always with ICSI (intracytoplasmic sperm injection), where a single sperm is injected directly into each egg.

  • Embryos develop in the lab — usually for 5 to 6 days, until reaching the blastocyst stage.

  • One embryo is transferred — typically in a medicated cycle that prepares the lining of your uterus.

  • Pregnancy test — around 9 to 14 days after transfer.

If you'd like a fuller picture of each stage, our companion article “IVF With Frozen Eggs: Step-by-Step” walks through the medical process in detail.

Legal considerations in the UK

UK law is, on balance, fairly protective and clear for solo mothers using donor sperm at a licensed clinic. A few important things to know:

You will be the legal parent

If you give birth in the UK, you are automatically the legal mother. According to HFEA guidance, a single woman who has treatment with sperm donated at a UK-licensed clinic does not need to consent to legal parenthood, she's the child's mother automatically, and the donor has no legal rights or responsibilities. If you choose to use sperm donated by someone known to you, you may want to come to a separate agreement. 

Donor anonymity ended in 2005

Most donor-conceived children in the UK now grow up knowing that their donor is identifiable. Since a change in UK law in 2005, anyone conceived from a donation made on or after 1 April 2005 can request:

  • Non-identifying information (physical description, ethnicity, year of birth, medical history, donor's reasons for donating, sometimes a personal message) from the age of 16.

  • Identifying information (full name, date of birth, last known address) from the age of 18.

This shapes the choice in two big ways:

  • Your donor cannot be truly anonymous. Even outside the HFEA system, the rise of consumer DNA testing services means full anonymity is no longer realistic.

  • Most UK clinics actively encourage early, age-appropriate conversations with donor-conceived children about their origins.

The 10-family limit

UK law allows one sperm donor's sperm to create a maximum of 10 families in the UK. This limit is designed to reduce the chance of donor-conceived half-siblings unknowingly meeting and to give your child a sense of how many half-siblings they may have.

If you're using a known donor

If your donor is someone you know, a friend, for example, donating through a UK-licensed clinic still gives you the strongest legal protection. If the same person donates outside a clinic (“at home” or via a private arrangement), the law becomes much less clear, and the donor may be considered the legal father with associated rights and responsibilities. Specialist legal advice is essential in this scenario.

If you live or move outside the UK

Laws vary considerably between countries. Some restrict donor sperm to married heterosexual couples; some require donor anonymity; some have no rules. If you're considering treatment outside the UK, or moving abroad after treatment, take legal advice — particularly around your child's legal parentage and citizenship.

Choosing a sperm donor through a clinic 

Most UK clinics work with one or more sperm banks. You'll typically be given a profile of each donor that includes:

  • Physical characteristics: height, eye colour, hair colour, ethnicity, skin tone.

  • Medical history: both personal and family.

  • Education and occupation.

  • Often a personal description, motivation for donating

  • Sometimes a childhood photo (rules vary by clinic).

UK donor sperm is rigorously screened by licensed clinics, including for HIV, hepatitis B and C, HTLV, and a panel of common genetic conditions. The HFEA's Code of Practice sets minimum standards.

There's no “right” way to choose a donor. Some women prioritise physical resemblance to themselves; others prioritise health history, the donor's personality, or matching ethnicity, religion or cultural background. There is no evidence that any particular approach leads to better outcomes for the child.

Practical questions worth asking your clinic

  • How many donors are currently available, and how recently were they recruited?

  • How long is the typical wait for a suitable donor matching my preferences?

  • Are donors UK-recruited, or imported from overseas? (If imported, check they meet UK identifiability rules.)

  • Are the donor's sperm samples already in storage at your clinic, or will they be shipped in?

  • Will I be able to reserve more sperm from the same donor in case I want a second child?

  • How many UK families has this donor already created? (The 10-family limit applies in the UK only — donors used internationally may have created additional families abroad.)

Emotional and practical considerations

Counselling is part of the process

UK clinics are required to offer counselling before you start treatment with donor sperm. This is not a hurdle it's intended to be a genuinely useful conversation. A specialist fertility counsellor can help you think through how you'll talk to your child about their origins, how you'll respond if they want to find their donor at 18, and how you'll navigate the day-to-day of solo parenting.

Telling your child

Modern clinical and psychological consensus in the UK is that donor-conceived children benefit from being told about their origins early and openly — long before any formal milestones. The Donor Conception Network is a long-running UK charity that provides resources for parents on how and when to talk to children about being donor-conceived.

Family and friends

Telling people you're becoming a solo mother by choice can be its own emotional process. Some friends and family will be unequivocally supportive; others may have questions or, occasionally, opinions you didn't ask for. 

Success rates and treatment pathways

Success rates for IVF with donor sperm and your own frozen eggs depend on the same factors that drive any IVF cycle, chiefly the age you were when your eggs were frozen, how many you have available as well as the quality of the sperm. 

Donor sperm itself does not lower your success rates, donor sperm at UK-licensed clinics is high quality, screened, and selected from healthy donors.

What does it cost in the UK?

Costs vary significantly between clinics, but as a rough guide:

  • Donor sperm vials — typically £950 to £1,500 per vial in the UK, depending on the bank.

  • Thawing and ICSI — the HFEA estimates around £2,500 for thawing and embryo transfer, although some clinics quote £4,600 or more.

  • Frozen embryo transfer (additional) — typically £1,500 to £2,500 if you're freezing extra embryos for future use.

  • Counselling, scans and bloods — sometimes included, sometimes added.

  • Storage — for any remaining eggs or embryos, an ongoing annual fee.

NHS funding for IVF varies by region and is generally limited to women with a recognised medical need. It is rarely available for solo mothers using their own previously frozen eggs in elective circumstances. Check with your GP and your local Integrated Care Board.

Practical takeaways: what should you do next?

  • Have an open consultation with the clinic that holds your eggs about treatment with donor sperm. Get a full written cost plan.

  • Book the counselling session your clinic offers, even if you feel sure of your decision. It's a useful space to think out loud.

  • Read the HFEA pages on donor conception, legal parenthood, and donor information rights.

  • Talk to other solo mothers via UK communities such as the Donor Conception Network or solo mother by choice groups. Hearing real stories is more useful than any policy document.

  • Get legal advice if you're using a known donor or if you have any complexity around your relationship status.
