Using donor sperm is the route to parenthood for single women, same-sex female couples, and some male-factor infertility cases where no other option is available. In the UK, all donor sperm treatment must be carried out at an HFEA-licensed clinic, and the legal framework around donor identity is among the most important things to understand before you begin.

Who Uses Donor Sperm?

Single women who want to conceive without a partner use donor sperm with IUI (if no other fertility factors are present) or IVF.

Same-sex female couples use donor sperm for IUI or IVF. Some couples also use reciprocal IVF — where one partner provides the eggs and the other carries the pregnancy — which combines donor sperm with IVF.

Male-factor infertility. Where a male partner has azoospermia (no sperm) that cannot be addressed by surgical retrieval, or where surgical retrieval finds insufficient sperm, donor sperm is the alternative to adoption or remaining childless.

Genetic conditions. Where a male partner carries a serious genetic condition, donor sperm may be chosen to avoid passing it on.

UK Law: Identifiable Donors

The most important UK-specific fact: all sperm donors at UK-licensed clinics must be identifiable.

Under the Human Fertilisation and Embryology Act 2008 (as amended), any child conceived using donor sperm at a UK clinic has the right, from age 16, to request non-identifying information about the donor (physical description, occupation, personal messages left for donor-conceived people). From age 18, they can request identifying information — the donor's name and last known address.

Donors must consent to this before donating. They cannot change their mind later.

This legal framework — which has been in place since 2005 — means the UK has a significant shortage of sperm donors. Donors are limited to contributing to a maximum of 10 families in the UK. Waiting times for donor sperm from UK banks can be months to over a year.

Overseas Sperm Banks and UK Clinics

Many UK patients use sperm imported from overseas sperm banks — primarily from Denmark (Cryos, European Sperm Bank) and the United States. This is permitted: overseas sperm can be used at UK-licensed clinics, provided the donor has agreed to identifiability under UK law.

Overseas donors recruited after the UK's identifiable-donor rules came into force (2005) and who consented to be identifiable under UK law can be used at UK clinics. Many major overseas banks now have a separate pool of donors who have consented to UK identifiability.

Overseas donor sperm is typically imported frozen. The clinic handles the logistics of ordering and receiving the sample.

Treatment Options: IUI vs IVF with Donor Sperm

IUI with donor sperm is the standard first-line treatment for single women and female couples with no identified female fertility factors. Stimulated IUI with donor sperm has per-cycle live birth rates of approximately 10–15% for women under 35. Over multiple cycles, cumulative success rates can be 40–50%.

IVF with donor sperm is used when:

  • IUI has been attempted and has not resulted in pregnancy (typically after 3–6 cycles)
  • There is a female fertility factor (low ovarian reserve, tube problems, endometriosis) that makes IVF more appropriate
  • The patient is over 38 and the efficiency of IVF is preferred over multiple IUI attempts

Choosing a Donor

Donors at UK-licensed clinics or overseas banks (with UK consent) can be selected on the basis of:

  • Physical characteristics (height, eye colour, hair colour, skin tone)
  • Blood type
  • Educational background and occupation
  • Personal messages or audio profiles (where offered by the bank)

UK law does not allow matching on the basis of religion or ethnicity in a way that discriminates, but clinics and banks offer enough information to allow patients to choose a donor whose profile they feel comfortable with.

The HFEA register maintains records of all donors used at UK-licensed clinics, which is how the child's right to information at 16 and 18 is fulfilled.

Telling Children About Donor Conception

The consensus among fertility counsellors, psychologists, and HFEA guidance is that donor-conceived children benefit from knowing about their origins from an early age — ideally in early childhood rather than at adolescence or as adults. Research consistently shows that later disclosure (particularly in adolescence or adulthood) is associated with more psychological disruption than early disclosure.

The UK does not legally require parents to tell children about their donor conception origins. However, because the HFEA maintains the register and children can access it at 16, it is possible for a child to discover their origins independently. This is another argument for disclosure on the parents' own terms and timeline.

Many clinics offer or can refer to specialist fertility counselling and resources for donor-conception families. The Donor Conception Network (DCN) is a UK charity with extensive resources for families using donor conception.

Costs

IUI with donor sperm (private): £800–£1,500 per cycle in clinic fees. Donor sperm samples typically cost £900–£1,500 per vial (overseas banks) or vary at UK banks. Medication for a stimulated IUI cycle adds £100–£400.

IVF with donor sperm (private): £5,000–£8,000 per cycle, plus donor sperm costs.

NHS funding: Some ICBs fund IUI or IVF with donor sperm for eligible patients, including single women and same-sex female couples. Eligibility criteria are the same as for heterosexual couples in most ICBs (following NICE guidance's non-discriminatory approach), but in practice policies vary. Check your ICB at nestie.co/nhs.

Frequently Asked Questions

Q: Can I find my own donor (not through a clinic)?

A: In the UK, using sperm from an unregistered, unlicensed donor — for example, a friend or contact found through the internet — outside of an HFEA-licensed clinic is legal for the person donating and the recipient. However, it is not regulated, the child will have no right to donor information via the HFEA register, and there is no health screening. There are also legal risks around parental status. Using a known donor through an HFEA-licensed clinic is the safest route — it provides all the regulatory protection while still allowing you to use someone you know.

Q: What legal status does a sperm donor have?

A: A sperm donor who donates at an HFEA-licensed clinic has no legal parental status and no financial obligation toward any child conceived. The donor is not the legal parent. This is established by the HFEA framework. An informal (unlicensed) donor may in some circumstances be able to claim — or be assigned — parental responsibility, which is a significant legal risk.

Q: Can I use the same donor for a second child?

A: Yes, provided the donor is still active on the register and their family limit (10 families in the UK) has not been reached. Many families do plan to use the same donor for siblings. It is worth confirming with your clinic or the bank whether additional samples from the same donor can be reserved.

Q: Are donor-conceived children able to find donor siblings?

A: The HFEA register records how many families a donor has contributed to, and donor-conceived adults can access this information at 18. The Donor Sibling Registry and other informal networks also facilitate contact between donor-conceived people who share the same donor, independently of the HFEA system.

Q: How do I know the donor's sperm has been screened?

A: HFEA-licensed clinics are required to use donors who have been screened for a panel of infectious diseases (including HIV, hepatitis B and C) and genetic conditions. Most banks also offer optional extended genetic carrier screening. The specific screening panel is disclosed by the clinic or bank.
