Switzerland Informal Sperm Donation

Parentage, custody, and support context for known-donor arrangements

Legal framework and considerations

Switzerland regulates medically assisted reproduction under the federal Reproductive Medicine Act (Fortpflanzungsmedizingesetz / FMedG) and related ordinance. Formal sperm donation is a clinic-only, tightly gated pathway—not a free-for-all private market.

Core rules (formal donation)

TopicRule
Who may access donor spermMarried couples, including married female couples (access expanded from 1 July 2022). Unmarried couples and single women remain outside lawful clinic donation under current federal framing.
Donor anonymityAnonymous donation is prohibited. Donor identity is registered; donor-conceived people may access identifying information later.
Donor statusAn official (regulated) sperm donation does not create a legal father–child relationship; the donor has no maintenance/education/inheritance duties under that regime.
Egg donation / surrogacyProhibited under current FMedG (reform discussions continue).
Donor limitsLaw caps children per donor (commonly described as eight).
