A Complete Guide to Surrogate Mother Requirements and Qualifications

Most women who wonder about surrogate mother requirements assume they don’t qualify before they’ve read the actual criteria. They spot one thing — a past C-section, a BMI near the limit, a history of depression — and close the tab.

That’s the wrong call. Surrogate qualifications exist to protect you, not weed you out. At Physician’s Surrogacy, every application is reviewed by board-certified OB/GYNs who apply clinical judgment — not just a form.

Here is every requirement, explained plainly, with the medical reasoning behind it.

The Core Surrogate Mother Requirements

These are the baseline eligibility criteria. Meet all of them and you’re ready to apply.

• Age: 20.5–40.5 years old
• Prior pregnancy: At least one full-term, uncomplicated delivery; currently raising that child
• BMI: Below 35 at application; below 37 at embryo transfer (case-by-case for 35–37)
• Lifestyle: Non-smoker, non-smoking household, alcohol-free, no recreational drug use
• Mental health: Not currently using antidepressants or anti-anxiety medications
• Residency: U.S. citizen or permanent resident in a surrogacy-friendly state
• Pregnancy history: No more than six total pregnancies; no more than three C-sections
• Communicable disease: Free from HIV and hepatitis B or C
• Financial: Financially self-sufficient independent of surrogate compensation

Read on for the reasoning behind each requirement — and honest answers to the questions we hear most often from applicants.

Age Requirements for Surrogacy

The American Society for Reproductive Medicine (ASRM) recommends a carrier age range of 21 to 45. Our physicians set a tighter window: 20.5 to 40.5 years old.

The minimum reflects legal contract requirements. Most states require women to be at least 21 to enter a binding surrogacy agreement — the 20.5 floor gives a small buffer for the screening timeline before that birthday.

The upper limit is clinical. Maternal age above 40 meaningfully increases the risk of gestational diabetes, preeclampsia, and preterm delivery. Our OB/GYN team sets this threshold using the same data they rely on in their own obstetric practices — not an arbitrary industry cutoff.

For a deeper look, see our guide to surrogate age requirements.

Prior Pregnancy and Parenting Requirements

You must have given birth to at least one child and be actively raising that child. This requirement has two separate purposes.

First, it confirms your body can carry a pregnancy to term without major complications. A prior uncomplicated delivery is the strongest clinical predictor of how a future pregnancy will go. No lab result or health screening tells the story as clearly.

Second, it protects your psychological health. In gestational surrogacy, the baby you carry shares no genetic connection to you — the embryo comes from the intended parents’ or donors’ genetics. After delivery, the baby goes home with its family.

Surrogates who return home to their own children carry a meaningfully lower risk of attachment difficulties or postpartum depression. Our post on why surrogates must be parents covers the psychological reasoning in full. All candidates also complete a psycho-social evaluation with a licensed social worker to confirm emotional readiness.

BMI Requirements for Surrogates

The BMI requirement at application is below 35. At embryo transfer, the maximum is 37 — a small buffer for medication-related weight changes during the preparation cycle.

These thresholds align with ASRM guidance and the standards set by the IVF clinics we partner with. Higher BMI correlates with increased risk of gestational diabetes, hypertension, preeclampsia, and cesarean delivery. A lower BMI at transfer also improves medication response and embryo implantation rates, according to research published by the National Institutes of Health.

If your BMI is close to 35, we can connect you with a nutritionist and review your application individually. Some applicants ask about GLP-1 medications like Ozempic or Wegovy as a path to the threshold.

The answer depends on timing and medical clearance — our guide to GLP-1 medications and surrogacy covers what our physicians look for. For a full breakdown, see our article on BMI requirements for surrogacy.

Lifestyle Requirements

Surrogates must be non-smokers living in a non-smoking household, free from recreational drug use, and prepared to abstain from alcohol throughout the process and pregnancy.

These are not negotiable. Smoking, drugs, and alcohol during pregnancy are directly linked to congenital abnormalities, low birth weight, and preterm delivery — findings established across decades of obstetric research and documented by the CDC.

Mental Health and Medication Requirements

Women currently using antidepressants or anti-anxiety medications are not eligible to apply. This is a clinical safeguard, not a judgment about mental health history.

Pregnancy changes how medications metabolize, and many psychiatric medications carry pregnancy warnings. We won’t ask a candidate to stop taking medication she genuinely needs.

A past history of situational depression that fully resolved — with no ongoing treatment — is reviewed individually, not categorically rejected. Our physicians look at timing, severity, and current mental health status. All candidates complete a psycho-social evaluation with a licensed social worker. Spouses or partners participate too.

Pregnancy History: What Our OB/GYNs Screen For

When you apply, we request records from your previous OB/GYN. Our physicians review your full pregnancy and delivery history to identify any past complications that could raise risk in a surrogacy pregnancy.

The following histories may affect eligibility:

• Placental abruption
• Intrauterine growth restriction (IUGR)
• Preeclampsia or eclampsia
• Gestational diabetes requiring medication (insulin or Glyburide)
• Preterm delivery before 36 weeks where the cause was not avoidable
• HELLP syndrome
• Complete placenta previa
• Incompetent cervix
• Chronic hypertension requiring medication

Having one of these in your history doesn’t automatically disqualify you. Our OB/GYNs evaluate each case on its own merits — something a standard agency coordinator simply cannot do. For a complete breakdown of what typically disqualifies candidates, see our article on common surrogate disqualifications.

C-Section History and Surrogacy

A prior C-section does not automatically disqualify you. Most candidates with one or two previous C-sections are eligible to apply.

Three or more C-sections places you at the ASRM guideline limit. If that’s your situation, our physicians review your records individually — factoring in surgical history, uterine condition, and the time elapsed since your last delivery. The decision is always clinical, never automatic.

State Eligibility Requirements

Surrogacy law varies by state — sometimes dramatically. To protect both you and the intended parents, we work only in states where surrogacy contracts are legally enforceable and where pre-birth parentage orders can be obtained.

Physician’s Surrogacy currently accepts surrogate applications from 41 states. States where we don’t currently work — including Michigan, Louisiana, and Nebraska — restrict compensated surrogacy by statute.

If you’re unsure whether your state qualifies, our article on best states for surrogates gives a full breakdown. The fastest way to confirm your eligibility is to submit an application — it takes about 10 minutes.

What Physician’s Surrogacy Does Differently

Most agencies measure surrogate mother requirements by running candidates through a checklist. A coordinator compares your answers to a form, and the form decides.

At Physician’s Surrogacy, in-house board-certified OB/GYNs review every application. These are physicians who manage high-risk pregnancies in clinical settings — and they apply the same judgment here.

The Surrogate Screening Process, Step by Step

Passing the basic surrogate mother requirements gets you into our screening process. Here’s exactly what that looks like at Physician’s Surrogacy.

What Qualifies vs. What Doesn’t: A Plain-Language Breakdown

Some surrogate mother requirements are hard stops. Others are evaluated individually by our physicians. Here’s the breakdown, in plain language.

What Happens After You’re Cleared

Clearing our physician-designed screening carries real weight. Meeting the surrogate mother requirements isn’t a formality at PS — an in-house OB/GYN has reviewed your records, evaluated your history, and confirmed you’re medically appropriate for a gestational surrogacy pregnancy.

That’s not the same as a coordinator checking boxes. Once cleared, you’re part of the largest active pre-screened surrogate pool in the U.S. Intended parents can see your profile and initiate a match — sometimes within days of clearance.

Not Sure If You Meet the Surrogate Mother Requirements?

The shortest path to an answer is applying. Our application takes about 10 minutes, immediately flags whether you meet the surrogate mother requirements for your state, and gets your history in front of a coordinator — not a bot.

Women who assumed they didn’t meet the surrogate mother requirements turn out to be strong candidates more often than you’d expect. Don’t count yourself out before a physician has had the chance to review your history.

Physician’s Surrogacy is the only agency where OB/GYNs personally review every application. See if you qualify — we evaluate every candidate individually.
