Gestational surrogacy in Mexico: medical process and safeguards

What is gestational surrogacy?

In gestational surrogacy, an embryo created through IVF is transferred to a person who agrees to carry the pregnancy. The gestational carrier does not provide the egg used to create that embryo. Eggs and sperm may come from intended parents or donors, depending on medical indication, consent and applicable law.

Gestational surrogacy combines several distinct areas: fertility treatment, obstetric care, psychological support, informed consent, legal representation, financial administration and planning for the child after birth. These roles should be clearly separated so that every participant understands who represents their interests.

Typical medical process

1. Initial consultation. A fertility specialist reviews reproductive history, prior treatments, available gametes or embryos and the reason surrogacy is being considered.
2. Independent evaluations. Intended parents, donors when applicable and the prospective carrier complete medical and psychological assessment. Each participant should have an opportunity to ask questions privately.
3. Legal review before treatment. Independent attorneys review eligibility, consent, the agreement, expenses, decision-making, insurance, parentage and post-birth documents.
4. Embryo creation or review. IVF may be performed using the agreed egg and sperm sources. Existing embryos require medical and documentation review.
5. Carrier preparation. The carrier’s uterine cavity and general health are evaluated. Medication and monitoring are individualized.
6. Embryo transfer. The number and timing of embryos transferred should be chosen with attention to clinical safety and the risks of multiple pregnancy.
7. Pregnancy and obstetric care. A positive test is followed by ultrasound and transition to an obstetric team. The carrier remains the patient and retains the right to informed medical decision-making.
8. Birth and post-birth process. The hospital, legal teams and intended parents coordinate documentation and newborn care according to the applicable rules.

Embryo genetic testing requires an individual clinical indication and does not guarantee a healthy embryo, pregnancy or birth. The benefit of routine PGT-A for everyone undergoing IVF has not been established.

Screening, consent and the carrier’s rights

Screening commonly reviews overall health, pregnancy history, uterine factors, infectious disease testing, medications, mental health, home support and the ability to understand the medical and emotional demands of the process. Evaluation must not be treated as a guarantee that pregnancy will occur or remain complication-free.

The carrier should have independent legal counsel, confidential medical conversations and psychological support. Consent is an ongoing process, not just an initial signature. The carrier retains autonomy over medical decisions, as addressed in SCJN AR 63/2024 (Spanish). Ask for current consent documents, the care plan, responsible professionals, complication and postpartum arrangements; documents alone do not prove implementation.

Legal planning for surrogacy in Mexico

Mexico does not have one uniform surrogacy pathway. Read Sinaloa’s Family Code, articles 282–297, with its amendments (Spanish). Article 282 addresses access to insemination and fertilization without distinctions based on sex, marital status or sexual orientation. Surrogacy-specific requirements also need review, including the citizenship condition in article 290. Eligibility must be assessed individually.

Article 284 distinguishes compensated and altruistic arrangements. Payment alone neither establishes exploitation nor ensures validity; consent, terms and participants’ rights require examination.

The scope of each Supreme Court case matters: AI 16/2016 examined Tabasco provisions; AR 63/2024 addresses carrier autonomy; AR 86/2024 illustrates the importance of formalities and the parentage route. CC 159/2025, decided in 2026, addresses non-contentious judicial proceedings in Mexico City where specific regulation was absent. It does not itself establish a uniform procedure for Sinaloa or guarantee immediate registration.

Before treatment, counsel should address parentage, birth registration, medical decisions, expenses, insurance, complications, embryo handling, privacy and disputes. Intended parents living abroad also need advice in their home jurisdiction. A contract does not, by itself, guarantee parentage or registration.

Costs, coordinators and agency questions

Total cost can include fertility evaluation, IVF, donor services, embryo testing, medication, carrier screening, legal representation for each party, psychological support, insurance, obstetric and hospital care, travel, agency or coordination fees and post-birth documentation.

Ask for an itemized estimate that identifies who receives each payment, which expenses are refundable, how funds are held, what insurance excludes and what happens if a transfer is cancelled or a pregnancy requires additional care. Do not rely on a single “guaranteed package” figure.

If an agency or coordinator is involved, request its legal name, responsible contacts, scope of work, privacy practices, complaint process and proof of how client funds are administered. ViaFERT’s medical services do not replace independent legal representation or agency due diligence.
