Most programs expect a surrogate to be at least 21, and many set an upper limit somewhere between the mid-30s and mid-40s. ASRM prefers carriers between 21 and 45, though individual clinics may set narrower cutoffs. Ask any program for its age policy and medical screening criteria in writing before you apply.
TL;DR:
- Clinic cutoffs vary: some stop around 35 to 38, while many accept applicants through 40 or 45; request written rules and exception procedures.
- Pregnancy risks, including gestational diabetes, preeclampsia, and cesarean delivery, rise with age, especially after 40, so older applicants may need added prenatal monitoring.
- Most programs require at least one uncomplicated pregnancy and delivery alongside medical and psychosocial screening for medical history, substance use, support, and financial stability.
- ASRM permits consideration above 45 only in rare cases with disclosed risks and informed consent; programs may add surveillance and recommend single embryo transfer.
- Colombian statutory age limits are unclear; applicants should verify local requirements with independent counsel and obtain each program’s medical criteria in writing.

What age ranges do clinics and professional guidance use?
Legal adulthood and program eligibility are two different things. A carrier must be of legal age, but most programs set the bar higher. ASRM's ethics guidance holds that a minimum age of 21 is reasonable, because it helps ensure the maturity needed to give informed consent and handle the physical and emotional demands of the postpartum period.
At the upper end, practice varies more:
- Some clinics cap eligibility in the mid-30s, around 35 to 38.
- Many programs accept carriers up to 40 or 45.
- ASRM says a carrier older than 45 may be considered in rare cases, with disclosure of the potential risks and informed consent.
What does this look like in practice? A 2024 systematic review and meta-analysis found the median age of gestational carriers was approximately 34 years. Cohort research likewise shows that carriers' ages often cluster under 40, so a healthy carrier in her late thirties or early forties may still qualify.
Because cutoffs and exception policies differ from one program to the next, ask for the applicable age limit and exception process in writing. A verbal "we usually prefer under 40" tells you very little.
Why do age limits exist?
Age and prior-pregnancy criteria can serve as safeguards, addressing medical risks and informed consent.
On the medical side, ACOG reports that pregnancy risks increase progressively with age, particularly after 40, including gestational diabetes, preeclampsia and higher cesarean rates. ACOG's clinical commentary adds that risks climb through the late 30s and 40s, and that early, regular prenatal care and surveillance improve outcomes for older pregnant people.
ACOG: risks of pregnancy complications rise progressively with age, most notably after 40. For a carrier, age is one factor programs may consider, not an automatic disqualification.
The ethical case is just as important. ASRM's committee opinion frames selection criteria such as age and prior pregnancy history as protections for the surrogate's autonomy and safety. Requiring at least one prior uncomplicated pregnancy matters because it lets a surrogate understand, from experience, what pregnancy and recovery demand before she agrees to carry for someone else.
Age bands also translate into practical care:
- Older carriers often receive added antenatal surveillance, especially at 40 and above.
- A program may consider a carrier's age and health when deciding what screening is appropriate.
- Prior pregnancy history shapes how a program reads a carrier's risk profile.
How do clinic and agency policies vary?
Two programs can read the same professional guidance and still reach different decisions. ASRM's ethics committee emphasizes that programs, not a single universal rule, set age limits, and that policies evolve as medical data change.
Differences that matter include strict cutoffs versus case-by-case review, the age at which extra monitoring begins, and the documentation required for an exception. A carrier's obstetric history, current health and the legal setting where the birth will take place can all change a program's answer.
Questions worth asking every agency or clinic:
- What is your minimum and maximum age for carriers, and is either flexible?
- How do you evaluate applicants just above your usual cutoff?
- What documents do you need for an exception, such as obstetric records or specialist letters?
- What added monitoring do you require for older carriers?
- Will you put the age policy in writing?
Pro Tip: Request the program's age-policy statement in writing and ask how it handles monitoring for older carriers.
What does screening cover beyond age?
Age is one filter among many. Most programs screen medical and psychosocial factors together, so it helps to know the full list before applying.
Medical checks usually include:
- Obstetric history, typically at least one uncomplicated pregnancy and delivery. In the meta-analysis above, only 1.7% of carriers were nulliparous, which shows how rare it is to carry without prior births.
- BMI limits. The CDC adult BMI calculator is a standard reference for checking your own number.
- Infection and chronic-disease screening.
- Review of prior uterine surgery and cesarean deliveries.
Programs may consider prior cesarean deliveries as part of their review of a carrier's obstetric history.
Psychosocial and behavioral checks usually include:
- Mental-health screening and a review of your support network.
- Substance-use testing.
- Criminal-record review.
- Financial stability requirements, so that compensation is not your only source of support.
Pro Tip: Gather your obstetric records and a current primary-care summary before your first application. It speeds evaluation considerably.
How are older carriers and exceptions handled?
ASRM's guidance allows that carriers older than 45 may be considered in rare cases, provided there is full disclosure of the risks and informed consent. This is the exception, not the norm, and programs approach it carefully.
When a program does consider an older carrier, it typically adds measures such as:
- More intensive antenatal surveillance throughout the pregnancy.
- Single embryo transfer. ASRM recommends single embryo transfer for gestational carrier cycles.
- Any additional evaluation should be determined by the medical team based on the carrier's circumstances.
An uncomplicated prior obstetric history can strengthen the case. A carrier with several smooth pregnancies and deliveries gives the medical team real evidence of how her body handles pregnancy, which carries more weight than age alone.
How is intended parents' age different?
The age of the intended parents is a separate question from carrier eligibility. It mostly affects the gametes, not the pregnancy. One review comparing outcomes notes that intended-parent age affects oocyte quality separately from the carrier's suitability.
A younger carrier does not erase embryo risks tied to older oocytes. Discuss options for evaluating or addressing those risks with a fertility specialist. When donor gametes are used, donor age may be an important factor in embryo quality.
If you are an intended parent, discuss your embryo-source strategy with your fertility specialist while the carrier search runs in parallel.
What are the legal age requirements for surrogates in Colombia?
We cannot verify a statutory minimum or maximum surrogate age under Colombian law, so seek advice from a qualified lawyer. What we can say is how the two layers fit together. Legal capacity to consent is the floor, and the program's medical criteria sit on top of it. In practice, programs set their own medical eligibility criteria. ASRM considers a minimum age of 21 reasonable and preferably recommends carriers be between 21 and 45.
Seek independent legal counsel about the rules that apply to a surrogacy arrangement in Colombia. ACOG's committee opinion on family building through gestational surrogacy describes the ethical, medical, psychosocial and legal complexity of these arrangements.
If you are weighing a Colombian program, ask for the age rules in writing and have a lawyer who represents your interests review them. Our guide to how surrogacy works in Colombia walks through the process step by step, and our overview of surrogacy in Colombia explains the legal and medical supports clients can expect.
Do age limits and laws differ for intended parents across jurisdictions?
They can, and widely. Our team works with intended parents from many countries, and the rules that apply to you depend on where you live, where the child will be born and where you plan to establish legal parentage. Some jurisdictions set explicit age limits for intended parents. Others set none, and many leave the decision to individual clinics.
We do not publish a universal age cap for intended parents, and we would be wary of any program that does without asking where you live. The better question is what your home country will recognize. Parentage, citizenship and travel documents for a child born abroad each depend on local law, so check them with a qualified lawyer before you commit.
Our work with international couples and our comparison of international versus USA surrogacy cover how those differences play out. We also support gay couples, lesbian couples, transgender couples, heterosexual couples and singles, and the legal questions differ for each.
How does surrogate age affect legal and ethical aspects in Colombian programs?
Age touches both consent and care. Ethically, the question is whether a woman can fully understand what she is agreeing to. That is why age floors and prior pregnancy requirements exist: they support genuine informed consent and protect the surrogate's autonomy.
Legally, the surrogate's age matters in two ways. She must have capacity to sign her agreements, and an older carrier who needs added monitoring or an exception needs clearer documentation of the risks she has accepted. ACOG's guidance on gestational surrogacy points to appropriate obstetric care and independent legal counsel for this reason.
At our agency, we treat age as one input into a broader review of medical history, support and understanding of the process. Our team includes legal and medical professionals alongside people with personal surrogacy experience. Our article on Colombia's support for LGBT couples shows how that same care extends to every kind of family.
What I would tell you before you apply
Age rules are safeguards, not arbitrary barriers, and many applicants fit comfortably inside the typical range. Start by screening yourself against the checklist above. Collect your obstetric records, contact reputable providers, and ask each one for its age policy in writing. Seek independent legal and psychosocial advice before signing anything. When two programs give you different answers, compare them with published guidance from ASRM and ACOG rather than taking either at face value.

FAQ
What is the minimum age to be a surrogate?
ASRM considers a minimum age of 21 reasonable and prefers carriers between 21 and 45. Programs may set their own criteria.
What is the maximum age for a surrogate?
Programs differ. Many set upper limits from the mid-30s to the mid-40s, and ASRM allows rare cases above 45 with full risk disclosure. Ask each program for its exact cutoff in writing.
Do you need a prior pregnancy to be a surrogate?
Usually, yes. Programs typically require at least one uncomplicated pregnancy and delivery, because it helps a surrogate give truly informed consent. In the meta-analysis, only 1.7% of carriers had never given birth.
Can a surrogate be too old?
It depends on the program and the carrier's health. Pregnancy risks rise with age, so older carriers face closer review and added monitoring. A healthy carrier in her late thirties or early forties may still qualify.
How do you request an exception to an age limit?
Ask the program how its exception process works and what documents it needs, such as obstetric records and specialist letters. A strong, uncomplicated pregnancy history helps, and the program should explain any added monitoring in writing.
