Wyoming Informal Sperm Donation

Legal Framework and Considerations

Wyoming’s legal framework for informal sperm donation, including at-home artificial insemination (AI), is governed by the 2002 Uniform Parentage Act (UPA), codified in Wyo. Stat. § 14-2-401 et seq.. Unlike many states rooted in the 1973 UPA, Wyoming’s adoption of the 2002 version provides a broader, more modern approach to assisted reproduction, explicitly defining "donor" and "assisted reproduction" without mandating physician involvement for donor non-paternity. This progressive stance offers potential flexibility for informal AI, though ambiguities remain due to limited case law and practical application. No substantive changes as of October 2025.

Core Provisions

Provision Statute Key Implications
Assisted Reproduction § 14-2-402(a)(i) Defines as a method of causing pregnancy other than sexual intercourse, including intrauterine insemination, egg/embryo donation, IVF, and intracytoplasmic sperm injection. Broadly encompasses at-home AI; no physician required.
Donor Non-Parentage § 14-2-403(c) Donors have no parental rights or duties for children conceived via assisted reproduction. Applies to informal AI; protects against support/custody claims without physician mandate.
Intent-Based Parentage § 14-2-501 & § 14-2-504 Establishes parentage by birth, adoption, acknowledgment, or judicial order. Presumes paternity for husbands in marital contexts; donors excluded under § 14-2-403. Unmarried recipients may need adoption or acknowledgment for non-biological parents.
Custody & Child Support Title 20, Ch. 2 (Support) & Title 20, Ch. 5 (Custody) Non-parents (donors) owe no support; custody defaults to birth/intended parents. Disputes resolved via statutory presumptions and intent evidence, not biology alone.
Withdrawal/Disputes & Surrogacy § 14-2-901 et seq. (Surrogacy) Gestational agreements allowed; informal donation under broader UPA. Post-birth disputes via adjudication; cross-state enforcement via UIFSA.

Key Court Cases (2024-2025)

No Wyoming Supreme Court cases directly address informal sperm donation under the 2002 UPA as of October 2025. General precedents affirm donor protections:

2025 outlook: With no recent rulings, the framework remains permissive but untested; courts likely to uphold donor non-parentage if intent is documented, per UPA model.
