KnownDonor introduces people. It is not a clinic and never handles sperm. Safety · UK law

Safe & respectful

Wanting a child is personal. We keep things calm, clear and respectful.

No sex, no ‘natural insemination’

This is a place for donation without sex: home insemination with a cup and syringe, treatment at a licensed clinic, or co-parenting. Asking for or offering sex or ‘natural insemination’ (NI), or sending sexual messages, is not allowed. We suspend profiles that do this. Received a request like that? Please report it from the profile.

  • Block and report on every profile
  • Clear rules: serious family plans, no flirting
  • No buying or selling of sperm, and no payment through us
  • We never collect, store, test, post or deliver sperm, and you shouldn't either: in the UK that needs an HFEA licence
  • Open donation: your child has the right to know where they come from
  • We're not a clinic and don't give medical or legal advice
