Informal/at-home AI may fit when statutory definitions of assisted reproduction and \u201cdonor\u201d are met and any writing/consent rules are satisfied. Natural insemination is almost never within donor-exemption design. Always read the current official code for Colorado and use counsel for multi-state facts.",
