Modern family planning has evolved rapidly. Where once traditional sperm banks were the only option, digital platforms now open entirely new pathways: sperm donation apps offer a more personalised—and often more private—approach to fulfilling the desire to have children, for singles, heterosexual couples and the LGBTQ+ community alike. In this article we introduce the leading apps, explain their standout features and highlight the UK legal considerations you need to know in 2025.
What Are Sperm Donation Apps?
Sperm donation apps connect donors and recipients directly, frequently bypassing the clinic route. Users create profiles detailing health, appearance, education and interests. Depending on the platform, you can opt for anonymous donation or arrange ongoing contact.

Legal Considerations: What You Need to Know in the UK
In the UK, sperm donation is regulated by the Human Fertilisation and Embryology Authority (HFEA) under the Human Fertilisation and Embryology Act 1990 (as amended). Donors must be approved and registered with the HFEA and undergo mandatory health screenings and genetic tests. For donations made after 1 April 2005, donors cannot remain anonymous; donor-conceived individuals have the right to access identifying information once they turn 18.
For private arrangements via apps, it is advisable to draw up a legally binding agreement in advance. Some platforms offer template agreements, but consulting a solicitor specialising in reproductive law is recommended. Bear in mind that regulations vary across UK nations (England, Scotland, Wales, Northern Ireland), so always check local requirements.
