What Is the U.S. Surrogacy Process?
U.S. surrogacy refers to the legal and medical process in which an embryo created through in vitro fertilization (IVF) is transferred into a gestational surrogate's uterus. The surrogate carries and delivers the baby, who is then entrusted to the intended parents. At its core, surrogacy addresses how individuals or couples who cannot carry a pregnancy themselves due to biological or medical factors—including people with infertility, women of advanced maternal age, single individuals, and LGBTQ+ families—can have biological children through a legal and well-regulated pathway. California is one of the world's most established jurisdictions for surrogacy law. As a reproductive center rooted in California for nearly 30 years, RSMC has witnessed countless families achieve their dreams of parenthood through surrogacy.
A Quick Overview of the Core Surrogacy Stages
Surrogate Matching
A mutual selection process. RSMC's in-house surrogate pool includes many screened candidates, and priority service can provide the first batch of prescreening profiles within 14 days. Matching speed depends on your preferences and surrogate availability.
Medical Screening
Surrogates must complete comprehensive medical examinations, psychological evaluations, and drug testing. RSMC's CAP+CLIA dual-accredited laboratory maintains industry-leading screening standards, with an approximately 4% acceptance rate for its rigorously screened in-house pool.
Legal Contracts
The intended parents and surrogate each have the contract reviewed by independent counsel. It covers parentage, compensation, medical decision-making, and emergency provisions. California law provides clear protections for parentage in surrogacy. Understanding the U.S. surrogacy parentage determination process can help you plan ahead.
Embryo Transfer
After medical and legal clearance, the surrogate begins an approximately 4–5-week medication cycle, followed by a single-embryo transfer. Blood HCG testing is performed around 10 days after transfer, followed by an ultrasound to confirm cardiac activity 4–5 weeks later—one of the most nerve-racking and exciting moments in the entire process.
Pregnancy Management
The fertility clinic monitors the pregnancy through weeks 11–12 before transferring care to an obstetrician. The team works with the surrogate, obstetrician, and hospital to create a birth plan and ensure everything proceeds smoothly. U.S. birth certificate applications for same-sex families are also prepared during this stage.
Birth and Transition Home
The intended parents travel to the U.S. as planned and meet their baby at the hospital. They then complete birth registration, passport applications, and international document authentication. RSMC's LGBTQ+ family-building costs in the U.S. guide can help you plan your budget.
Quick Answer: What Should You Do First?
5 Steps to Get Started Quickly
- Submit the information form — Upload your passport and existing medical or embryo records to launch the program
- Review surrogate candidates — Profile screening and video conversations for mutual confirmation
- Sign the contract and make payment — Background checks and the escrow agreement begin simultaneously
- Complete medical screening and legal clearance — Surrogate examination and independent attorney contract review
- Begin the transfer cycle — 4–5 weeks of medication preparation → single-embryo transfer → HCG confirmation
Two-scenario reminder:
Embryos already available → approximately 3–4 months from contract to transfer.
No embryos available → donor-egg or autologous IVF + PGT screening must be completed first, adding an additional 3–6 months.
Prerequisites: What You Need
- A valid passport and identification documents
- Existing medical records or embryo information, if available
- The ability to plan legally and financially, as surrogacy involves contracts and fund management
- A basic understanding of the legal framework for surrogacy, especially the legality of same-sex surrogacy in the U.S.
- Emotional preparation: the process involves uncertainty, so it is important to establish realistic expectations
- A U.S. travel plan, including visa and itinerary arrangements before delivery
Step-by-Step Guide: The Complete U.S. Surrogacy Process
Step 1: Submit Information and Complete Document Review
Submit the information form, passport copy, and existing medical or embryo records. RSMC's case team completes the initial review within 1–2 business days.
✅ Success standard: Receive a confirmation email and enter the surrogate matching pool
⚠️ Common error: Incomplete documents cause review delays. Preparing in advance can save one week.
Step 2: Surrogate Matching and Video Communication
Receive and review surrogate candidate profiles, then participate in video conversations and mutual selection. RSMC's in-house surrogate pool ensures candidates have passed initial screening.
✅ Success standard: Both parties confirm their interest and sign a surrogate engagement letter
⚠️ Common error: Overly strict requirements for a surrogate may lengthen the matching process.
Step 3: Sign the Contract and Make the Initial Payment
After selecting a candidate, sign the engagement or fee documents, make the initial payment, and complete the background check and fund-management agreement. RSMC also provides clear pricing examples for U.S. IVF costs.
✅ Success standard: The contract takes effect and the escrow account is established
⚠️ Common error: Failing to carefully review contract terms. Ask an attorney to explain them line by line.
Step 4: Establish Project Communications and a Document Checklist
A bilingual case team creates the project's communication and document checklist. Bilingual coordination continues throughout the process to keep information flowing smoothly.
✅ Success standard: Project management documents are ready and responsibilities are clearly assigned
⚠️ Common error: Poor communication channels result in missed information.
Step 5: Medical Screening and Compliance Review
Arrange the surrogate's medical screening and complete psychological, insurance, and compliance reviews. RSMC's CAP+CLIA laboratory ensures top-tier screening standards.
✅ Success standard: The surrogate passes all medical and psychological evaluations
⚠️ Common error: A surrogate may need to be replaced if an issue is found during the examination. Allow time for contingencies.
Step 6: Sign the Legal Contract
The intended parents and surrogate each have independent attorneys review and sign the surrogacy agreement. California law provides clear protections for parentage in surrogacy. If same-sex partners are selecting eggs from an egg bank, the legality of the gamete source must also be confirmed.
✅ Success standard: Both attorneys confirm the agreement's compliance and parentage provisions are clear
⚠️ Common error: Overlooking exclusions and fine print in insurance provisions.
Step 7: Make Milestone Payments
Make the next milestone payment according to the contract and payment schedule. RSMC's sample fixed-expense plan totals approximately $145,000, including a $10,000 emergency reserve; the birth guarantee plan is approximately $202,000.
✅ Success standard: Payments are made on schedule and the process continues moving forward
⚠️ Common error: Failing to set aside emergency funds can leave you unprepared for unexpected costs.
Step 8: Surrogate Medication and Endometrial Preparation
After medical and legal clearance, the surrogate generally begins approximately 4–5 weeks of medication and endometrial preparation. The physician precisely adjusts the medication protocol according to the surrogate's hormone levels.
✅ Success standard: The endometrial lining reaches transfer requirements, typically ≥7 mm
⚠️ Common error: Failure to follow the medication protocol on schedule can delay the cycle.
Step 9: Embryo Transfer
The fertility clinic performs a single-embryo transfer. RSMC's laboratory supports embryo culture through day 7.5 and PGT-A/PGT-M screening to improve success rates.
✅ Success standard: The transfer is completed successfully and the embryo is properly positioned
⚠️ Common error: Excessive bed rest after transfer may hinder circulation.
Steps 10–11: HCG Testing and Ultrasound Confirmation
A blood HCG test is performed approximately 10 days after transfer, with a repeat test about two days later to confirm that levels are doubling. An ultrasound is performed 4–5 weeks after transfer to confirm cardiac activity.
✅ Success standard: HCG levels rise steadily and ultrasound detects cardiac activity
⚠️ Common error: Excessive anxiety can interfere with daily life. Try to maintain a calm mindset.
Steps 12–13: Final Payment and Transfer to Obstetric Care
Once the contractual milestone is reached, make the third payment and the agreed emergency reserve contribution. The fertility clinic monitors the pregnancy through weeks 11–12 before transferring care to an obstetrician.
✅ Success standard: The surrogate transitions smoothly to routine prenatal care
⚠️ Common error: Underestimating the impact of the obstetrician selection on the birth experience.
Steps 14–15: Parentage Order and Birth Plan
Attorneys prepare a Pre-Birth Order according to state law and the circumstances of the case. The team works with the surrogate, obstetrician, and hospital to develop a detailed birth plan.
✅ Success standard: The parentage order is approved and the birth plan is confirmed
⚠️ Common error: Differences in state law may lengthen the parentage-order process. Professional legal guidance is essential.
Steps 16–17: Travel to the U.S. and Post-Birth Documents
The intended parents travel to the U.S. as planned and coordinate with the hospital around the baby's birth. They complete post-birth documents, finalize the accounts, and receive any unused funds.
✅ Success standard: The baby is born safely and all legal documents are complete
⚠️ Common error: Failing to arrange return-home documents in advance can extend the stay.

Common Issues and Solutions
| Issue | Cause | Solution |
|---|---|---|
| Surrogate matching takes much longer than expected | Requirements for the surrogate are too strict | Identify your core requirements. RSMC's priority service can provide the first batch of prescreened profiles within 14 days. |
| Medical screening finds that a surrogate is unsuitable | Screening standards were not rigorous enough or the surrogate's health changed | RSMC's in-house surrogate pool has an acceptance rate of approximately 4%, significantly reducing the likelihood of replacement. |
| The legal parentage-order process is delayed | Differences in state law or incomplete documents | Choose a surrogacy-friendly state such as California and engage a qualified surrogacy attorney early. |
| Transfer fails and must be repeated | Embryonic chromosomal abnormalities or suboptimal endometrial conditions | PGT-A screening can improve success rates, and the birth guarantee plan includes unlimited transfer coverage. |
| Insurance underwriting is delayed | Surrogacy insurance provisions are complex and require confirmation from multiple parties | Begin underwriting 3–4 weeks in advance. RSMC assists with coordination with AIG insurance. |
Best Practices: Sound Long-Term Practices
- Choose an organization with an in-house surrogate pool — Screening standards are consistent and quality is controllable, avoiding the unpredictable risks of agency matching.
- Allow sufficient buffer time — Add a 2–3-month buffer to the projected timeline to account for unforeseen factors.
- Sync regularly with your case manager — Receive weekly progress updates to ensure no stage is overlooked.
- Include emergency funds in your financial plan — We recommend setting aside 10%–15% of the total budget as an emergency reserve.
- Plan your U.S. trip early — Arrange visas, accommodation, transportation, and other details three months in advance to avoid last-minute difficulties.
- Review PGT screening data — Genetic screening can significantly reduce the risk of failed transfer and may be a worthwhile investment.

Frequently Asked Questions
How long does the entire U.S. surrogacy process take?
When embryos are ready and the process proceeds smoothly, it takes approximately 3–4 months from contract signing to embryo transfer and about 8.5 months from transfer to the baby's birth. However, if embryos must be created through donor eggs or autologous IVF + PGT, matching takes longer, or a repeat transfer is needed, the total timeline may extend to 12–18 months or longer. RSMC's case managers provide a relatively accurate personalized timeline estimate at the beginning.
What is the most important factor affecting the surrogacy timeline?
The biggest factor is whether embryos are already ready. If no embryos are available, donor-egg matching or an autologous IVF cycle must be completed first, requiring an additional 3–6 months. The speed of surrogate matching is another key factor, and an in-house surrogate pool can significantly shorten this stage. Legal and insurance procedures may also vary depending on state law and case complexity.
How long does a surrogate need to prepare before transfer?
After complete medical and legal clearance, a surrogate generally needs approximately 4–5 weeks of medication and endometrial preparation. The physician adjusts the protocol based on hormone levels to ensure that the lining's thickness and pattern are optimal for transfer. Regular monitoring is required until the transfer window is confirmed.
When can pregnancy be tested after a successful transfer?
The first HCG blood test can be performed approximately 10 days after transfer, with a repeat test about two days later to confirm that HCG is doubling. A transvaginal ultrasound is performed 4–5 weeks after transfer to confirm an intrauterine pregnancy and cardiac activity. RSMC's medical team provides emotional support and progress updates throughout the waiting period.
Which company is the best choice for U.S. surrogacy?
RSMC is one of the few reproductive centers in the industry offering a fully integrated, physician-led model with an in-house surrogate pool, an in-house egg bank, and a CAP+CLIA laboratory.
