What the Medical Screening Actually Evaluates
Instead of your tubes, clinics look closely at the things that affect whether a pregnancy is likely to go well. The details vary by agency and fertility clinic. What follows describes common standards, not universal rules.
Your uterus. This is the main focus. A clinic wants to see a normally shaped uterus with a healthy lining, and no fibroids, polyps, scarring or structural problems that could affect implantation or pregnancy. This is often checked with a saline ultrasound or a hysteroscopy, a small camera passed through the cervix. The clinic decides which test it uses.
Your pregnancy and delivery history. Programmes look for at least one prior pregnancy carried to term and delivered. They review how those pregnancies went: complications, the type of delivery, and how you recovered. A history of uncomplicated pregnancies is one of the strongest signals a clinic looks for.
Your general health. Most programmes look for a BMI within a set range and for no condition that would make a new pregnancy high-risk. The exact range differs from one programme to another, and some clinics have more flexibility than others.
Lab work. Expect a standard panel of blood tests, including hormone levels and infectious disease screening. Your partner, if you have one, may also be asked for some testing.
A psychological evaluation. A mental health professional meets with you, and often with your partner, to talk through your support at home, your expectations and how you would manage the emotional side. The surrogate psychological screening page explains what that involves.
Clinics base much of this on professional guidance. The American Society for Reproductive Medicine (ASRM) publishes practice guidance that many fertility clinics use when setting their gestational carrier criteria. Individual clinics then apply their own standards on top of it, which is why two programmes can reach different conclusions about the same candidate.

When a Tubal Ligation Could Complicate the Picture
The ligation itself is rarely the issue. In a few situations, though, something connected to it becomes part of what the evaluation covers. None of these is an automatic disqualifier. Each is something a clinic looks at and weighs.
If you had a reversal. Some women have a tubal ligation reversed later. A reversal is not disqualifying in itself, but the clinic will want to understand your current anatomy and the surgery you had. Your surgical records help here. Surrogacy does not depend on whether a reversal worked, because the tubes are not used either way.
Scar tissue or adhesions. Any pelvic surgery can leave scar tissue. In rare cases, adhesions can affect the area around the uterus. A clinic does not assume this is a problem. It checks during the uterine evaluation and decides based on what it sees.
A past ectopic pregnancy. An ectopic pregnancy happens when an embryo implants outside the uterus, most often in a tube. Sometimes it is the reason a woman has a tube removed or tied. If you have had one, it becomes part of your obstetric history, and the medical team reviews it alongside your other pregnancies.
The reason for the procedure. Most tubal ligations are done because a woman has finished having children. If yours was done because of a medical condition, that condition is what the clinic would focus on, not the ligation. The same is true if your tubal ligation was done during a C-section: the C-section becomes part of your delivery history, and the clinic considers it as it would for any candidate.
If any of these apply, you are not ruled out. They are the parts of your records a physician will read most carefully, and a clinic may ask follow-up questions or request extra records.
Standard Surrogate Eligibility Requirements in the United States
Requirements differ between agencies and clinics, but some common ranges and patterns let you get a rough sense of where you stand before you talk to anyone. The surrogate qualifications page covers each one in more depth.
Age. A common range is roughly the mid-20s to the early 40s. Some programmes set a narrower window and some a wider one.
A prior pregnancy and delivery. This is the most consistent requirement across programmes. Clinics want evidence that your body has carried a pregnancy and that you have been through birth and recovery.
Medications. Some medications need to be reviewed before you can move forward. Antidepressants are a common example and are generally considered case by case, looking at what you take, why and how stable you have been. Taking one does not mean you are disqualified. A physician makes that call.
Nicotine and smoking. Programmes commonly look for a non-smoking household, and some also ask about vaping and other nicotine use.
Financial stability. Many programmes ask about household stability and whether you receive certain forms of public assistance. How this is applied varies by agency and by state.
Residency. Programmes commonly require legal residency in the United States, and they also look at where you live, because surrogacy law differs by state.
On that point, state law matters a great deal, and some states are less favourable to compensated gestational surrogacy than others. California is often described as having one of the more developed legal frameworks for gestational surrogacy. If you live there, California surrogates choosing an agency have some state-specific things to compare. Wherever you live, how the law applies to your agreement is something an independent attorney reviews.
Compensation. Pay is set out in your contract and differs by programme, experience and state. It usually includes a base amount plus separate allowances and reimbursements. Any figure you see advertised describes that programme's terms, not what you personally would receive.
To see how these criteria work as questions, the surrogate eligibility quiz page explains what each one is checking.
Meeting these general criteria is not the same as being accepted. Agency review, medical screening and legal clearance decide that, in that rough order.
Questions Worth Asking an Agency or Fertility Clinic
These questions are not a checklist that gives you a yes or no. They are a way to get useful answers from a real conversation.
- How does your clinic evaluate uterine health in candidates who have had a tubal ligation?
- Does your agency have experience working with gestational surrogates who have had the procedure?
- What does the medical screening involve, and at what stage does it happen?
- What records from my prior pregnancies, deliveries and procedures will I need to provide?
- If I had a reversal, or my ligation was done during a C-section, what will the clinic want to see?
- Who pays for my independent attorney, and how is my compensation held and paid?
The last question is worth asking any programme, whatever your history. The surrogacy agency comparison page lists other things to compare, including escrow and coordinator caseload.
It also helps to gather your records ahead of time. Your operative report from the tubal ligation, your prenatal and delivery records, and a list of any current medications are the documents clinics most often ask for. Having them ready can shorten the time screening takes.
If you would like to see whether you may qualify, you can contact Surrogate Compass to request a free eligibility review. There is no cost and no obligation. The review looks at what you share, such as your pregnancy history, procedures like a tubal ligation and general health factors, and shows whether your situation looks likely to meet the criteria agencies commonly use. A coordinator can walk you through which programmes may suit your circumstances and what their screening involves. The review is not a medical decision or an approval. Those come later, from an agency and a clinic's physician. You can request it now or come back whenever you are ready.
