Surrogate Requirements: Who Qualifies to Become a Surrogate in 2025-2026?

When I started looking for a surrogate, the first thing I wanted to know was who this person would actually be. It's the same question I hear from intended parents all the time, and the same one women ask when they're wondering whether surrogacy is something they could do.

The answer isn't a single checklist. The American Society for Reproductive Medicine (ASRM) sets baseline requirements, then each fertility clinic adds its own, and the agency adds more on top if you're working with one. Knowing how those layers fit together helps you find a match faster, or figure out whether surrogacy is right for you.

Here's what the requirements look like in 2025 and 2026, and what happens when someone falls into a gray area.

Why These Requirements Exist

Before any of this feels discouraging, know that these rules aren't arbitrary gatekeeping. They protect the surrogate's health, improve the odds of a healthy pregnancy, and keep everyone safe legally and emotionally.

The ASRM built its guidelines on decades of reproductive medicine research. Most U.S. fertility clinics follow them closely, but each clinic has the final say on who it approves for an embryo transfer. An agency may layer its own criteria on top of the clinic's, so two agencies can hold different standards for the same candidate.

The fertility clinic has the final word on medical clearance, no matter what an agency or matching platform tells you.

Age Requirements

Most programs in 2025 and 2026 require surrogates to be between 21 and 40 years old. The ASRM formally recommends 21 to 45, but in practice most agencies and clinics cap it at 40 to lower medical risk.

Why 21 is the minimum

Twenty-one is the age of full contractual capacity in every U.S. state. A surrogate needs to sign a binding legal agreement, and she needs enough life experience to understand what she's taking on. It also leaves time for her to have completed at least one prior pregnancy, which is required.

Why 40 is typically the cutoff

Pregnancy risks rise meaningfully after 40, including higher rates of gestational diabetes, preeclampsia, and cesarean delivery. IVF medications also respond more predictably in a younger uterus. Some clinics will review candidates between 40 and 42 case by case if the applicant has an excellent pregnancy history and strong medical clearance.

Prior Pregnancy History

This is the single most important requirement, and it's non-negotiable: you must have carried at least one pregnancy to term without major complications.

This has nothing to do with biology. Modern surrogacy is gestational, so the embryo carries no genetic material from the surrogate. The requirement exists to prove the surrogate's body can carry a healthy pregnancy. It also means she already knows what pregnancy and postpartum life feel like, which matters.

What counts as a complication?

Fertility clinics review full obstetric records, not just a candidate's own summary. Conditions that may disqualify a surrogate include:

Preeclampsia or eclampsia
Gestational diabetes that required insulin (diet-controlled gestational diabetes is often reviewed case-by-case)
Multiple preterm births (before 36 weeks)
Postpartum hemorrhage requiring transfusion
Recurrent pregnancy loss
Placenta previa or placental abruption

A single uncomplicated prior vaginal or cesarean delivery, followed by a healthy postpartum recovery, is the standard baseline. Most women who have had a healthy pregnancy will meet this requirement.

How many C-sections is too many?

Most programs follow ASRM guidance and won't approve a surrogate who has had more than two or three cesarean deliveries. The concern is that repeated C-sections can create uterine scarring that increases risk in a subsequent pregnancy. The specific limit varies by clinic, so confirm directly with the fertility clinic involved in the journey.

BMI Requirements

Body mass index is a standard part of surrogate screening. Most programs require a BMI of 32 or lower, though some set the threshold at 33 or 35. Individual fertility clinics make the final determination, and some programs may review candidates with a BMI just above their stated threshold case by case.

A higher BMI is associated with elevated risk of gestational diabetes, hypertension, blood clots, and complications during delivery, including challenges with anesthesia in a cesarean. These are the safety reasons behind the requirement, not appearance or judgment.

If you're close to the cutoff, the best step is to speak directly with the clinic or program about their specific standard before investing time in the full application process.

Lifestyle Requirements

These requirements are about creating the healthiest possible environment for the pregnancy from the moment screening begins.

Tobacco, nicotine, and drug use

Surrogates must not smoke, vape, or use tobacco products. Most programs require candidates to be nicotine-free for at least six to twelve months before applying, and urine nicotine testing is standard. Marijuana use is also disqualifying, even in states where it's legal, because no level of THC exposure during pregnancy has been established as safe.

Alcohol

Surrogates must abstain from alcohol entirely during the journey. No amount of alcohol has been proven safe during pregnancy, and most programs ask about current alcohol use during screening as well.

Stable home environment

A surrogate needs a stable, supportive home life. At least one person who can step in if she needs to rest, get to appointments, or go on modified bedrest. Childcare coverage needs to be in place if she has kids at home. None of this is about judging anyone's living situation. It's about making sure she's not left without support when she needs it most.

Financial Requirements

One rule catches people off guard: you can't be relying on this money to pay your bills. If you're on government cash assistance, public housing, or Medicaid when you apply, most programs won't take you.

That rule is there to protect the surrogate. Surrogacy should be a choice you make freely, not something you do because you're desperate for money. When rent is the reason, everything gets harder for everyone. Compensation is meant to honor your time and what the journey costs your body and your life. It's not a lifeline.

If you're trying to make sense of the actual numbers, I broke down how much surrogates really get paid in a separate post.

Mental Health Requirements

Psychological screening is standard in most surrogacy programs. A licensed mental health professional will typically evaluate the surrogate before the medical process begins. The evaluation isn't about finding reasons to disqualify someone. It's about confirming she's ready, flagging anything worth discussing, and preparing her for what's ahead.

Conditions that may prevent clearance include uncontrolled mental health disorders, recent significant psychiatric episodes, or active substance use. Antidepressants are a gray area: some fertility clinics are comfortable with certain medications, while others aren't, and many agencies have stricter policies than clinics. If you're currently taking any psychotropic medication, the honest move is to disclose it early so the right clinic can evaluate your specific situation.

Past episodes of postpartum depression that have been fully treated and resolved are often evaluated individually, especially when significant time has passed.

Legal and Residency Requirements

Surrogates in the United States are generally required to be U.S. citizens or legal permanent residents (green card holders). This is about ensuring the surrogate can sign an enforceable surrogacy contract and that all parties are protected under U.S. law.

Where you live also matters. While surrogacy is legal in most states, some states have laws that make the process more complicated. Surrogacy-friendly states such as California, Illinois, Nevada, Oregon, Washington, and New Hampshire provide a smoother legal path. Louisiana and a handful of other states present more hurdles. Your reproductive attorney will advise on whether your state's laws affect your eligibility or the structure of your contract.

Criminal Background Checks

A background check is required for the surrogate and typically for any adults living in her household. Violent offenses or crimes involving children are disqualifying. Minor past issues may be reviewed depending on the program, though honesty early in the process is always the right approach.

What Happens if You Don't Quite Meet the Requirements?

Not every potential surrogate checks every box on the first try. A few situations worth knowing about:

Tubal ligation: This does not disqualify you. Because gestational surrogacy uses IVF embryos and does not involve your own eggs, your tubes are irrelevant to the process.
Past C-sections: One or two prior cesarean deliveries is generally acceptable. Three or more is where most clinics will pause and review more carefully.
Antidepressants: Some clinics will approve candidates who take certain medications for depression or anxiety. Others will not. Being upfront about your medications allows you to find the right match rather than losing time in a program that will ultimately decline your application.
BMI slightly above threshold: Some programs will evaluate candidates just above their stated BMI cutoff if everything else is strong and the fertility clinic agrees to review.
Endometrial ablation: This procedure destroys the uterine lining and is a disqualifier for surrogacy. The uterus cannot sustain a pregnancy after ablation.

A Note on Independent Journeys

Even in an independent journey, the fertility clinic's requirements still apply. The ASRM guidelines are the medical standard whether or not an agency is involved. This is one reason independent journeys work well: you're not paying an agency to screen someone the clinic might reject anyway. But it does mean independent IPs need to know these requirements cold so they can have informed conversations with potential surrogates from the very start.

Key Takeaways

Surrogates must generally be between 21 and 40 years old, with at least one successful prior pregnancy and no major obstetric complications.
BMI under 32 to 35 is the standard range, with the fertility clinic having final say on individual cases.
No smoking, vaping, marijuana, or recreational drug use. A substance-free home is required.
Financial independence from the compensation is a requirement. Surrogates on government cash assistance or Medicaid typically do not qualify.
Psychological screening is standard and is meant to support the surrogate, not disqualify her.
The IP's fertility clinic always has the final word on medical clearance, regardless of what an agency or platform may say.
