The surrogacy process runs in seven stages: application, medical and psychological screening, matching, legal contracts, medical preparation and embryo transfer, pregnancy, and delivery and recovery. From first application to delivery, it commonly takes an estimated 12 to 18 months, and some journeys take longer. If you are reading this before telling anyone, you are probably trying to work out whether that year fits your body, your family and your work. This guide lays out what happens at each stage, who does what, and where the waiting happens.
It covers gestational surrogacy, where the embryo is created from the intended parents' or donors' eggs and sperm and you have no genetic link to the baby. Traditional surrogacy, which uses the surrogate's own egg, is legally complex, varies widely by state and is rarely practised. It is not covered here.
Before You Start: What Surrogacy Actually Requires
Most reputable programmes start from similar benchmarks, drawn partly from guidance published by the American Society for Reproductive Medicine (ASRM). These are common ranges, not universal rules:
- At least one prior pregnancy carried to term, usually with you raising the child.
- Age, commonly somewhere around 21 to 40, though programmes and clinics set their own limits.
- Non-smoker, and no use of nicotine or recreational drugs.
- A healthy BMI, with the cut-off varying by programme and clinic.
- No medical history that a physician considers a significant risk in a new pregnancy.
Every agency and clinic sets its own criteria, and a medical team reviewing your records makes the decision. A woman who falls outside one programme's range may fall inside another's. The surrogate eligibility quiz explains what each common question is for.
The practical demands matter as much as the medical ones. Expect many appointments at a fertility clinic, sometimes in another city, plus legal meetings, calls with your coordinator and regular contact with the intended parents. Emotional readiness is assessed too. Carrying a child you will not parent is a different experience from your own pregnancies, and programmes require a psychological evaluation for that reason.
Passing a preliminary eligibility check is not acceptance. Agency, medical and legal screening decide whether you go forward.
Step 1: Application and Preliminary Screening
The first contact is paperwork. You fill out an application with an agency, usually online, covering:
- Personal details and household situation
- Obstetric history: each pregnancy, how you delivered, any complications
- Lifestyle questions: smoking, medications, work, travel, support at home
- Often a background check, sometimes for your partner too
The agency reviews this against its own criteria and usually asks for your prior delivery records. At this stage it is asking a narrow question: does anything on paper rule you out before a clinic looks? A pass at this stage means the agency is willing to take your file further. It is not a guarantee of medical clearance, a match or acceptance.
Estimated time: days to a few weeks, often depending on how quickly your hospital releases records.
Some surrogates proceed independently, matching directly with intended parents without an agency. Medical screening, separate attorneys and payment arrangements are still required, and you take on the coordination yourself. The guide to choosing a surrogacy agency covers what an agency's role should include.
Step 2: Medical and Psychological Evaluation
The intended parents' fertility clinic conducts the medical evaluation, not your own OB. In many programmes this happens after matching, because the clinic is the one the intended parents have chosen. ASRM guidance is the professional standard clinics draw on for these evaluations.
The medical side commonly includes:
- A physical exam and review of your obstetric records
- A uterine assessment, often a saline sonohysterogram or a hysteroscopy, to check the shape and lining of your uterus
- Blood work, including infectious disease testing, and often testing for your partner
- Drug and nicotine screening
The psychological side usually combines a standardised written assessment with an interview by a licensed mental health professional. It covers why you want to do this, who supports you at home, how you expect to feel after delivery, and whether you understand the role. A partner is often asked to join part of it.
If screening finds a condition the clinic considers a risk, the clinic will usually explain what it found. Sometimes that ends the process. Sometimes a condition can be treated and reassessed, and another clinic may weigh it differently. Either way, the finding is useful health information about your own body.
Estimated time: about 4 to 8 weeks for medical and psychological evaluations combined. The surrogate screening process guide goes through each test in more detail.
Step 3: Matching With Intended Parents
Matching is where your preferences carry real weight. The agency presents profiles of intended parents whose situation and wishes line up with yours, and passes your profile to them.
You typically share your background, your family, why you are considering surrogacy, and your preferences: how often you want contact during the pregnancy, how many embryos you are willing to have transferred, and your views on termination and selective reduction. Intended parents share their background, why they are pursuing surrogacy, and what they hope the relationship will look like.
If both sides are interested, the agency sets up a match meeting, often a video call with a coordinator present. It is a conversation, not an interview you pass or fail. Either side can decline afterwards, and you can say no to a match without giving a reason.
Estimated time: weeks to several months. Narrow preferences, a particular clinic location or a slow period at the agency all lengthen it.
Step 4: Legal Contracts and the Surrogacy Agreement
Once a match is agreed, attorneys draft the surrogacy agreement. You and the intended parents each have separate attorneys. Independent representation for the surrogate is standard practice, and the intended parents commonly cover its cost. Confirm both points with your agency before you match.
The agreement typically covers:
- Base compensation, allowances and reimbursements, and when each is paid
- Medical decision-making, including how many embryos may be transferred
- Selective reduction and termination
- Communication and contact during and after the pregnancy
- Health insurance, life insurance and who pays for each
- Delivery room access and the parentage process
No embryo transfer happens until the agreement is fully signed by everyone. Your attorney's job is to explain what each clause means for you. Surrogate Compass is not a law firm, and nothing here is legal advice. Ask your attorney anything you are unsure of before you sign.
Parentage is also arranged at this stage. In California, the Family Code supports gestational surrogacy agreements, and courts routinely issue pre-birth orders that establish the intended parents as the legal parents before delivery. Other states differ considerably, and some are restrictive. Your attorney explains what applies where you live and where you will deliver. California surrogates can read what California surrogates should know when comparing agencies.
Estimated time: about 4 to 8 weeks for negotiation and signing.
