Surrogate Health Requirements: The Complete 2026 Guide

August 25, 2026

Not every woman who wants to carry a baby for another family ends up qualifying. That catches many candidates off guard.

Health requirements exist for one clear reason. They protect the surrogate, and they give the baby she carries the safest possible start.

This guide walks through the physical, medical, and psychological standards agencies apply. It also covers the conditions that can disqualify a candidate, the ones that rarely do, and how Surrogacy by Faith reviews health requirements once an application comes in.

What Physical Health Requirements Must a Surrogate Meet?

Age and Reproductive History Requirements

Most agencies set an age window between 21 and 40. Younger candidates tend to face fewer pregnancy-related risks, which is why the cutoff exists at all.

The exact upper limit around how old a surrogate has to be shifts from one agency to the next. Because of that, it pays to check before assuming an application will get rejected on age alone.

Candidates also need at least one prior pregnancy carried to term, with no major complications along the way. That history shows a fertility clinic that her body has already handled pregnancy safely once before.

BMI and Weight Guidelines for Surrogates

A BMI of 29 or below has become the standard most agencies apply today. That is tighter than the 19 to 32 range some older resources still list.

Extra weight during pregnancy raises the risk of gestational diabetes and high blood pressure, according to Mayo Clinic research on pregnancy and obesity. In practice, it can also affect how well an embryo transfer takes.

Clinics calculate BMI at the very first screening, right alongside the BMI requirements for surrogacy review. Still, a candidate who falls just outside the range can often reapply once her BMI shifts back into it.

Pregnancy and Delivery History Standards

Delivery history carries real weight in the review. Most agencies want a candidate’s most recent birth to have happened within the last five years.

That birth should have occurred at 36 weeks or later, unless she carried multiples. Multiples routinely deliver earlier, so clinics account for that difference.

Even so, preterm delivery on its own does not always disqualify a candidate. Clinics look at the reason behind it before making a final call, since a single early birth tied to an unrelated cause reads very differently than a pattern of complications.

A Quick Snapshot of the Baseline Standards

Before moving into medical and lifestyle factors, here is the physical baseline most agencies, including Surrogacy by Faith, work from:

Age between 21 and 37 at Surrogacy by Faith, up to 40 at some other agencies
BMI of 29 or below at the time of screening
At least one prior pregnancy carried to term
Most recent delivery within the last 5 years, at 36 weeks or later

Every candidate still gets reviewed individually. These numbers set the starting point, not the final word.

What Medical Conditions Can Affect Surrogate Eligibility?

Chronic Conditions That Typically Disqualify a Candidate

Certain ongoing health conditions raise enough risk that most clinics decline to move forward with an application. For example, these include:

Uncontrolled diabetes or heart disease
Untreated thyroid disorders
Active autoimmune conditions that affect pregnancy
A missing or non-functioning uterus

A reproductive endocrinologist reviews each condition individually. No clinic rules a candidate out from a checklist alone.

Pregnancy Complications Agencies Screen For

A history of severe preeclampsia, HELLP syndrome, or placenta previa raises concern for future pregnancies too. So does a prior stillbirth.

A baby born with a serious injury tied directly to the pregnancy itself also draws closer review. Even then, none of these automatically end a candidate’s chances.

Instead, a specialist reviews the full medical record before ruling anyone out for good. Context always matters more than a single line item on a form.

Conditions That Do Not Automatically Rule You Out

A surprising number of common conditions leave eligibility intact. For instance, PCOS rarely blocks an application on its own, since eligibility depends more on how well the condition is managed than on the diagnosis itself.

Tubal ligation carries no weight either. Surrogacy relies on embryo transfer through IVF, not natural conception, so a tied tube changes nothing.

Similarly, a prior gestational diabetes diagnosis gets a case-by-case review. One or two previous C-sections usually clear screening too, though the exact number varies by clinic policy.

What Lifestyle and Background Requirements Apply to Surrogates?

Nicotine, Substance Use, and Medication Guidelines

Candidates need to be nicotine and vape-free for at least 12 months before applying. No recreational drug use can occur at any point in that window.

Because of the stakes involved, clinics verify this through drug screening rather than taking a candidate’s word for it. Antidepressants and anti-anxiety medications follow the same 12-month rule.

A past prescription does not disqualify anyone. Active use at the time of application does.

Legal, Residency, and Financial Requirements

Every candidate needs to be a US citizen or legal permanent resident. No felony conviction can exist for her, or for any adult in her household.

On top of that, financial independence matters too. Candidates receiving cash aid, public housing, or Section 8 assistance typically do not qualify.

A stable home and a reliable support network round out the picture. Overall, reviewers want to see people around a candidate for the physical and emotional weight of the journey, a standard covered in full detail here for anyone still unsure whether they qualify.

How Does Psychological Screening Fit Into Surrogate Health Requirements?

What the Evaluation Covers

A licensed psychologist conducts the evaluation, usually over a video call. The conversation walks through motivation, stress management, and the emotional realities of carrying someone else’s child.

ASRM guidance for practices working with gestational carriers shapes most of what agencies ask during that conversation. Support at home comes up too, along with how a candidate would handle a hard outcome.

Specifically, a failed transfer or an early pregnancy loss are the two scenarios most evaluations spend real time on. Both carry emotional weight that agencies want a candidate ready for in advance.

What Happens If a Candidate Does Not Pass

A failed evaluation rarely ends the process for good. Many candidates wonder what happens if they fail their psychological evaluation.

The honest answer is that agencies often flag specific concerns first. They then invite a reapplication once those concerns get addressed, sometimes after a candidate seeks additional support on her own.

How Do Agencies Verify Surrogate Health Requirements?

Medical Records and Screening Documents

Verification starts with paperwork. OB/GYN records, delivery records, and an insurance card all get submitted once a candidate begins the application process.

A medical team reviews every document before a candidate moves forward. In practice, missing or incomplete records slow this stage down more than any single health condition does.

Clinic Screening at the IVF Center

Once records clear, the candidate goes to the intended parents’ IVF clinic. Bloodwork, a drug test, and sonograms all happen there, as part of the wider surrogacy process.

Results typically take about two weeks. The matching process only continues once everything comes back clear, so this stage sets the pace for everything after it.

Frequently Asked Questions About Surrogate Health Requirements

Do Health Requirements Vary Between Agencies?

Yes. Most agencies follow similar baseline standards drawn from ASRM guidance, but specifics like BMI caps and age ranges shift from one agency to the next.

For that reason, disqualifications for surrogacy covers the most common differences in detail, agency by agency and clinic by clinic.

Can a Candidate With Endometriosis Become a Surrogate?

Often, yes. Endometriosis affects fertility more than it affects the ability to carry a pregnancy once an embryo transfer succeeds.

Clinics review each case individually rather than issuing a blanket rule. Severity and treatment history both factor into that review.

Does a Prior Miscarriage Affect Eligibility?

A single miscarriage rarely disqualifies a candidate. That is especially true if her other pregnancies went to term without complications.

Instead, clinics weigh the full reproductive history rather than one event in isolation. A pattern matters far more than a single loss.

Can Health Requirements Change Partway Through the Process?

They can, if new information comes up during screening. Occasionally, a clinic requests additional testing when something in a candidate’s bloodwork or ultrasound raises a question.

That is one reason a match sometimes doesn’t move forward for health reasons no one predicted at the start. It is not common, but it does happen.

Does a Prior Surrogacy Journey Change the Health Review?

Repeat surrogates face a slightly different review. The focus shifts toward recovery time between pregnancies and how prior journeys went.

Naturally, the question of how many times a woman can be a surrogate comes up often. Most agencies weigh long-term health over a hard numeric cap.

How Surrogacy by Faith Reviews Surrogate Health Requirements

Surrogacy by Faith’s Health and Eligibility Standards

Surrogacy by Faith sets its age cutoff at 37, tighter than the industry standard of 40. That lower ceiling exists specifically to support a lower-risk pregnancy for both surrogate and baby.

The agency applies the same BMI threshold of 29 or below described above. That standard sits alongside the full surrogate requirements list already covered in this guide.

Only PGT-A tested embryos get transferred at Surrogacy by Faith. As a result, that practice supports a 92% first-transfer success rate against a 40 to 60% national average, and it protects surrogates from unnecessary transfer attempts.

Support Through Every Stage of Screening

Most team members at Surrogacy by Faith have been surrogates themselves. Screening questions come from people who have personally sat through the same bloodwork and psychological evaluation.

That lived experience shapes how the team explains each requirement. It also shapes what it actually feels like to go through one, a foundation candidates can read more about through how to become a surrogate.

Women who meet these standards can start the surrogate application in just a few minutes. Intended parents ready to move forward with a health-conscious, faith-aligned agency can reach out through the intended parent application.
