Risks of Surrogacy

The Real Risks of Being a Surrogate: Medical and Emotional Realities

Every woman considering surrogacy deserves an honest picture of what it actually involves — including what can go wrong, what usually doesn’t, and what separates a well-managed journey from an unprotected one.

The risks of being a surrogate are real. Some match what comes with any pregnancy. Others are specific to carrying a genetically unrelated embryo or to the hormonal protocol involved in IVF. None of them are reasons to walk away without thinking — but all are worth understanding clearly before you commit.

At Physician’s Surrogacy, we believe that informed surrogates make better decisions and have safer journeys. This article covers what the research actually shows, what we do differently, and how to use this information to ask the right questions.

Key Takeaways

Surrogate pregnancies carry the same risks as any pregnancy, plus some that are specific to IVF and carrying a genetically unrelated embryo.
A 2024 study in the Annals of Internal Medicine found gestational carriers had an 8% rate of severe maternal complications — four times higher than naturally conceived pregnancies — making rigorous pre-screening and continuous physician oversight more important, not less.
The most documented medical risks are preeclampsia, preterm birth, and cesarean delivery — all manageable with proper monitoring.
Emotional risks are real and frequently underestimated: post-birth adjustment, pregnancy anxiety, and relationship strain are normal experiences that deserve honest preparation.
Physician’s Surrogacy’s preterm delivery rate is 50% below the national average — a direct result of physician-designed screening and ongoing clinical oversight at every stage of the journey.

What the Research Actually Says About Surrogate Pregnancy Risk

Most articles about surrogacy risks are vague. The research is more specific — and worth knowing.

A 2024 large-scale study published in the Annals of Internal Medicine analyzed over 860,000 singleton births in Ontario, Canada between 2012 and 2021. Researchers from ICES and Queen’s University compared outcomes across three groups: unassisted pregnancies, IVF pregnancies, and gestational carrier pregnancies. The findings were striking.

The rate of severe maternal morbidity was 2% for naturally conceived pregnancies, 4% for IVF pregnancies, and 8% for gestational carrier pregnancies.

Surrogates also showed higher rates of hypertensive disorders, postpartum hemorrhage, and preterm birth compared to women who conceived naturally — and these risks persisted even after accounting for factors like prior birth history and pre-existing health conditions.

This doesn’t mean surrogacy is unsafe. It means surrogacy carries a specific risk profile — and the quality of your screening and monitoring matters far more than most people realize.

Quick Answer

Yes, surrogate pregnancies carry elevated medical risks compared to naturally conceived pregnancies. The most documented are preeclampsia, preterm birth, and postpartum hemorrhage. These risks are real — and they’re also manageable when you have rigorous physician-designed screening and ongoing clinical oversight throughout your journey.

Medical Risks of Being a Surrogate

The risks below aren’t equally severe. Some are common and manageable; others are rarer but more serious. All are worth understanding before you commit.

Preeclampsia and High Blood Pressure

Preeclampsia — high blood pressure combined with signs of organ stress — is one of the most consistently documented risks in surrogate pregnancies.

Carrying a genetically unrelated embryo may create an immune challenge that some researchers link to higher rates of hypertensive disorders. The exact mechanism isn’t fully understood, but the data is consistent across multiple studies.

It can range from mild to severe. In serious cases it requires early delivery — which is why continuous blood pressure monitoring throughout the pregnancy matters, not just at intake.

Preterm Birth

Delivery before 37 weeks is more common in IVF pregnancies generally, and the risk increases further in gestational carrier pregnancies.

Preterm birth affects both the surrogate’s recovery and the newborn’s health outcomes. It’s one of the most consequential risks because its effects don’t stay with the surrogate alone.

Our physician-designed screening protocol identifies risk factors before the journey starts rather than managing complications after they appear — which is why our preterm delivery rate sits 50% below the national average.

Cesarean Delivery Common

Cesarean section rates are higher in both IVF and surrogate pregnancies compared to naturally conceived ones.

In many cases it’s planned ahead of time. But even a planned cesarean means a longer recovery, more post-operative care, and more time away from your family and your own daily life.

Know this going in. It changes the practical planning around your journey in ways that a vaginal delivery wouldn’t.

Postpartum Hemorrhage

Excessive blood loss after delivery is a documented risk in gestational carrier pregnancies, per the 2024 Annals of Internal Medicine study.

It’s manageable in a well-equipped delivery setting with experienced providers. But it’s a reason surrogate deliveries shouldn’t be treated as routine.

The hospital team should always know about the surrogacy arrangement in advance — not as an afterthought, but as part of standard preparation.

Multiple Pregnancy Risks

When more than one embryo is transferred, the chances of a multiple pregnancy rise sharply. Twins and higher-order pregnancies carry substantially higher risks — premature labor, low birth weight, and cesarean delivery among them.

This is one reason single embryo transfer (SET) has become the standard of care in responsible surrogacy programs.

If you’re evaluating an agency or fertility clinic, ask specifically about their embryo transfer policy. It tells you a lot about how seriously they take surrogate safety.

Hormonal Medication Side Effects

The uterine preparation protocol requires estrogen and progesterone. Progesterone injections in particular cause injection site soreness, bruising, and fatigue for most surrogates.

These are expected and temporary. But they’re a real part of the process — not a footnote — and women should prepare for them going in rather than being caught off guard.

Our article on hormones before embryo transfer covers what each medication does and what to expect week by week.

Tip:
Not every surrogate candidate will face every risk listed here. Your individual health history changes your specific profile. At Physician’s Surrogacy, our OB/GYN team reviews each candidate’s full medical history individually — not against a checklist — to understand what your journey would actually look like. Review our surrogate requirements to see where you stand.

Emotional Risks of Being a Surrogate

The emotional side of surrogacy is frequently underestimated — both by women going in and by agencies that don’t adequately prepare surrogates for what they’ll feel. These aren’t rare outlier experiences. They’re part of what a surrogate journey involves.

Post-Birth Adjustment

The most common emotional challenge surrogates describe isn’t grief over the baby — it’s adjustment. After nine months of physical changes, a major life commitment, and a close relationship with the intended family, the sudden end of that chapter can feel disorienting.

Some surrogates describe it as similar to finishing a major project or leaving a job they valued. Others feel relief. A smaller number experience genuine grief or sadness.

All of these responses are normal. What makes them manageable is having realistic expectations going in, a strong personal support system, and ongoing counseling access — not just a pre-journey psychological evaluation that ends at matching.

Anxiety During Pregnancy

Carrying someone else’s child adds a layer of responsibility to normal pregnancy worry. Some surrogates experience real anxiety, particularly around the baby’s health.

Clear communication channels with your care team and intended parents help. So does working with an agency where a physician is directly accessible for real medical questions — not just routing everything through a coordinator.

Attachment and the Post-Delivery Period

Most women ask at some point whether they’ll feel attached to the baby. The honest answer is layered. Gestational surrogates carry no genetic connection to the child, and most report that the emotional experience is genuinely different from carrying their own child.

Caring for a pregnancy for nine months does produce emotional involvement — just not the same kind as parenting.

Most surrogates describe the post-delivery period as manageable when they’re well-prepared. Psychological screening before the journey exists specifically to identify women who have realistic expectations and the emotional tools for this phase. Read a fuller treatment of this topic in our post on surrogate attachment to the baby.

Relationship Strain

Surrogacy affects your entire household. Your partner takes on more during the pregnancy. Your children notice changes. Medical appointments, physical demands, and the emotional weight of the process all have spillover effects on your family.

Having those conversations honestly before you apply is one of the most protective things you can do. Our post on emotional readiness for surrogacy walks through the questions worth asking yourself first.

Quick Weigh-Up

Thinking through the emotional side before you apply.

What helps

Strong personal support system at home
Ongoing counseling — not just pre-match psych eval
Clear expectations set before the journey begins

What to think about

Post-delivery adjustment is common even for well-prepared surrogates
Household dynamics shift for the full duration of the pregnancy
Takeaway
The surrogates who fare best emotionally are the ones who treated preparation as seriously as the application itself.

How Agency Choice Shapes Your Risk Profile

Here’s the part most surrogacy articles skip: the risks described above aren’t equally distributed across all surrogacy arrangements. The quality of your screening, the caliber of your ongoing medical oversight, and the responsiveness of your support system all affect your specific risk profile.

Most surrogacy agencies are coordination businesses run by non-medical staff. When a clinical concern arises, they relay information between you and outside physicians — but no one at the agency has the authority or training to step in directly.

Physician’s Surrogacy is the only surrogacy agency in the United States managed by practicing OB/GYNs. That structural difference translates into four concrete protections for surrogates:

1

Physician-Designed Screening

Our OB/GYNs built the screening protocol that evaluates every surrogate candidate. It goes beyond standard ASRM guidelines specifically to identify risk factors that checklist-based screening misses.

2

Active Pregnancy Monitoring

Our in-house physicians monitor clinical communications throughout the pregnancy — not just at the start. If your blood pressure, weight, or lab results show a concerning trend, a physician on our team reviews it directly.

3

Peer-to-Peer OB Consultation

If a complication arises, our doctors can speak directly with your delivering OB — not through a coordinator chain. That direct channel matters when timing is critical and decisions need to move fast.

4

3–6 Months of Post-Delivery Support

Physical and emotional recovery from a surrogate pregnancy doesn’t end on delivery day. Our support doesn’t either. We continue care for 3–6 months after birth — covering both the medical and psychological dimensions of recovery.

⚕️ The Physician’s Advantage

Risk Doesn’t Have to Be Left to Chance

Most agencies rely on outside physicians and coordinator chains. At Physician’s Surrogacy, practicing OB/GYNs lead the screening, monitor your pregnancy directly, and maintain a peer-to-peer consultation channel with your delivering doctor.

Our preterm delivery rate is 50% below the national average.

That outcome comes directly from physician involvement at every stage — not from luck. Learn about our clinical model.
