The Hidden Risks of Carrying Surrogacy Twins for Surrogates

Surrogacy is a physically demanding and emotional journey, but the impact you have on a family’s life is priceless. You’re literally making dreams come true!

However, if you’re looking into becoming a surrogate, you might have heard Intended Parents (IPs) talk about wanting surrogacy twins. It’s a common thought: “If we transfer two embryos, we can get our full family in one go and save money.”

It sounds efficient, right? A “two-for-one” deal. But here at Physician’s Surrogacy, we need to be real with you about what carrying surrogacy twins actually means for your body and the babies’ safety.

While the idea of delivering two adorable bundles of joy is heartwarming, the medical reality is much more complex. Today, we’re going to break down the known risks and costs associated with multiple births so you can make an empowered, informed decision about your body and your journey—especially if you’re considering a twin pregnancy for surrogates.

The “Two-for-One” Myth: Why Twins Are Harder on You

The desire for twins is often seen as a way to build a family faster.

But this perspective overlooks the significant physical toll on you, the surrogate. As one surrogate honestly shared in an online forum, “Even though I’ve had an uncomplicated pregnancy, it’s still the hardest physical thing I’ve ever endured.”

There’s also a big ethical question here: Is it right to purposely try for a high-risk pregnancy?

Many surrogates discover that most fertility doctors are unwilling to specifically try for a twin pregnancy for surrogates, given the higher medical risks. We’re not trying to scare you, but we want you to be safe. Let’s look at why the industry has shifted away from twins and what that means for you.

Why Twins Are No Longer the Goal with IVF

To understand why everyone is so focused on risk now, it helps to look at history.

When Multiple Embryos Were the Norm

Years ago, multiple pregnancies or twins were pretty common with in vitro fertilization (IVF). The reason was simple: the technology wasn’t as advanced as it’s today. Doctors had to transfer multiple embryos at the same time just to hope that one would stick.

They transferred multiple embryos to compensate for lower success rates. This practice led to a situation where multiple pregnancies in IVF became 20 times more common than in natural conception.

This history explains why some Intended Parents still have this “multiple embryo” mindset. As one person noted in a discussion, “I think they did that 10+ years ago, but now they don’t do that…” And they are right—the landscape has changed completely.

Modern IVF and the Rise of Single Embryo Transfer (SET)

With advances in technology—especially when using donor eggs or high-quality embryos—the goal of IVF has shifted. The goal was always to produce a pregnancy, not necessarily twins. The desired outcome is a healthy surrogate, a healthy delivery, and a healthy baby.

Now, transferring more than one embryo is generally not recommended by the American Society for Reproductive Medicine (ASRM). Single Embryo Transfer (SET) is the gold standard unless there’s a very specific medical reason to do otherwise.

This shift prioritizes your health as the gestational carrier. It’s a change grounded in research and real-world outcomes that show just how dangerous multiple pregnancies can be—including the risks of twins for surrogates.

The Risks of Surrogacy Twins

This is the part that is all about you. A twin pregnancy is automatically classified as high-risk. It places a much greater physical strain on your body than a singleton pregnancy. The medical community is very clear about these increased dangers, and the risks of twins for surrogates are well documented.

Increased Medical Complications

When you carry two babies, your body is working double-time. Here are the specific risks you face in a twin pregnancy for surrogates:

• Pre-eclampsia: This is a serious blood pressure condition. Research shows the risk is significantly higher in multiple pregnancies compared to singleton ones. This condition can lead to severe complications for both you and the babies, including seizures or the need for immediate delivery.
• Gestational Diabetes: You will face a higher likelihood of developing diabetes during pregnancy with multiples. This requires strict diet monitoring, blood sugar testing, and sometimes insulin.
• Postpartum Hemorrhage: There’s an increased risk of severe bleeding after delivery. Because the uterus has been stretched so much more, it has a harder time contracting back down, which can be life-threatening.
• Caesarean Section (C-Section): With twins, you have a much higher probability of needing a C-section. This is major abdominal surgery with a longer recovery time, a bigger scar, and increased risks of infection compared to a vaginal birth.

These aren’t just statistics on a page—they represent real possibilities that could impact your health and your ability to care for your own children while you recover. This is why we take the risks of twins for surrogates seriously.

The Emotional and Psychological Toll

The toll isn’t just physical; it’s emotional, too. One of the hardest things to talk about is selective reduction.

If a surrogate ends up carrying three or more fetuses (which can happen if an embryo splits), a physician might recommend selective reduction to reduce the number of fetuses to one or two. This is done to save the pregnancy and protect the health of the remaining babies.

However, this is an incredibly difficult decision for both the surrogate and Intended Parents. It’s fraught with emotional pain and ethical complexity. Choosing Single Embryo Transfer (SET) from the beginning avoids this potential heartbreak entirely—one of the reasons SET is often recommended in surrogacy twins discussions.

Beyond that, there’s the anxiety. A high-risk pregnancy means more doctor appointments, more monitoring, more bed rest, and more worry. That heightened state of anxiety can take a significant mental toll on you over nine months.

Risks to the Babies: Why “Healthy” Is Better Than “Two”

While your health as a surrogate is our top priority at Physician’s Surrogacy, we also have to look out for the little ones. The goal is a healthy outcome, and the stats on twins are sobering—especially in surrogacy twins scenarios.

The Danger of Premature Birth

Premature birth is the single biggest risk with twins. The risk of premature delivery skyrockets from 14% in singletons to 65% in twins.

• Average Pregnancy Length:
  • Singleton: 39 weeks
  • Twins: 36 weeks (often earlier)

These represent weeks of crucial brain and lung development that babies miss when born too early.

Prematurity often leads to lengthy, stressful stays in the Neonatal Intensive Care Unit (NICU). It can cause issues like respiratory distress syndrome, where the babies can’t breathe on their own.

Low Birth Weight and Long-Term Issues

Babies from multiple births are far more likely to be small. The risk of low birth weight jumps from 9% in singletons to 57% in twins.

Low birth weight is directly linked to a higher risk of developmental delays and neurological problems. The emotional cost of caring for children with long-term health needs is huge for the Intended Parents.

Other Scary Complications

• Twin-to-Twin Transfusion Syndrome (TTTS): This is a rare but dangerous condition in identical twins where blood flows unevenly between them. One baby gets too much blood (straining their heart), and the other gets too little (starving them of nutrients).
• Intrauterine Growth Restriction (IUGR): This is when one or more babies don’t grow at the proper rate.
• Increased Risk of Loss: Sadly, multiple pregnancies carry a higher risk of stillbirth or miscarriage.

Even simple genetic testing is riskier. Procedures like amniocentesis have a complication rate up to 5 times higher with twins than with a single baby.

The Hidden Costs: It’s NOT “Two for the Price of One”

Intended Parents often push for twins because they think they are saving money. This is a dangerous misconception. The reality is usually the exact opposite, and it’s one reason surrogacy twins aren’t treated as a “value option” by reputable clinics.

Skyrocketing Medical Bills

• Medical costs for delivery and newborn care can be four times greater for twins than for a single baby.
• NICU costs are astronomical. A lengthy NICU stay can lead to bills in the hundreds of thousands of dollars. We have seen families go massively in debt because of this.
• For international IPs, if they have to stay in the U.S. for months while their preemie babies grow strong enough to fly, the cost of hotels, food, and lost income is massive.

The Toll on the Family

The challenge doesn’t end when they leave the hospital. Raising two newborns at once is incredibly hard. As one parent put it, “1 kid for the first year is a lot. I can’t imagine 2 at the same time. It’s a rough period.”

If the babies have health issues from being born early, the ongoing therapy and medical costs can last a lifetime.

Why SET Is the Best Path for Surrogates

So, what does this mean for you as a surrogate candidate thinking about surrogacy twins?

Faster and Safer Matching

Here’s a secret: Being firm about Single Embryo Transfer (SET) can actually help you match faster.

Smart, well-informed IPs and reputable agencies (like us!) understand the risks of twins for surrogates. They are looking for a surrogate who shares their commitment to safety. When you say, “I prefer SET because I want a safe pregnancy,” you show that you’re educated and responsible.

The Doctor’s Role

Even if you wanted to carry twins, you would need approval from the fertility doctor (REI).

A surrogate is, by definition, healthy and fertile. If we put two embryos in you, there’s a very high chance both will stick—or one could split, resulting in triplets.

Doctors have an ethical duty to “do no harm.” When a doctor advises against a dual transfer, they are protecting you—because a twin pregnancy for surrogates can shift from “manageable” to medically complicated very fast.

As one person wisely noted online, a doctor willing to ignore these risks might “not be the best quality people to be working with.”

How Decisions Are Made Today

At Physician’s Surrogacy, the decision on how many embryos to transfer is data-driven. We look at:

• Embryo Quality: Has the embryo been genetically tested (PGT-A)? High-quality embryos have a great chance of sticking on their own.
• Egg Provider’s Age: Younger eggs usually mean better embryos.
• Your Uterus: We want to give the embryo the best environment without overcrowding.

Start Your Surrogate Journey Safely

The journey of surrogacy is an incredible gift. You’re offering to use your body to build a family. While the idea of twins might seem appealing to Intended Parents who are desperate for a family, the medical evidence is undeniable: the risks of twins for surrogates and the babies are just too high.

Single Embryo Transfer (SET) isn’t just a suggestion; it’s the standard of care. It’s designed to get everyone what they truly want: a healthy baby and a healthy surrogate who goes home safe to her own family.

Before you commit, do your research. Talk to us. Ask questions. We’re here to help you understand why we prioritize safety above all else. By choosing SET, you aren’t doing less; you’re doing the best thing possible for that future child—especially when the alternative is a twin pregnancy for surrogates.

Frequently Asked Questions

Why is carrying twins as a surrogate considered high-risk?

Carrying twins is high-risk because it puts massive strain on the surrogate’s body. It increases the chance of pre-eclampsia, gestational diabetes, and postpartum hemorrhage. It also makes a C-section much more likely, which is a major surgery with a longer recovery time than a natural birth.

What is Single Embryo Transfer (SET) and why is it the standard?

SET means transferring just one embryo into the uterus. It’s the standard because modern technology allows for high success rates without the dangers of twins. The American Society for Reproductive Medicine recommends it to keep both the surrogate and the baby safe from complications like premature birth.

Do intended parents really save money with surrogacy twins?

No, that is a myth. Surrogacy twins can cost up to four times more than a single baby due to complicated deliveries and NICU stays. If babies are born premature, the medical bills can be astronomical, far outweighing the cost of two separate, healthy surrogacy journeys.

What are the main risks for babies in a twin pregnancy?

The biggest risk is premature birth. 65% of twins are born early, compared to only 14% of singletons. This leads to low birth weight, breathing issues, and long-term developmental delays. There’s also a higher risk of complications like Twin-to-Twin Transfusion Syndrome.

How does agreeing to SET affect me as a surrogate?

Agreeing to SET makes you a very desirable candidate! It shows you prioritize health and safety. Most reputable agencies and Intended Parents want a surrogate who follows medical best practices, so you will likely be matched faster with a family that values your well-being—especially because they understand the risks of twins for surrogates.

Who makes the final decision on how many embryos to transfer?

It’s a collaborative decision, but the fertility doctor (REI) has the final say based on safety. They have an ethical duty to do no harm. While IPs and surrogates have input, reputable doctors will rarely agree to transfer two high-quality embryos because the risk is too great—particularly in a twin pregnancy for surrogates.
