Can You Be a Surrogate If You Had a Premature Baby?

A preterm birth in your history isn't always the end of the road. What matters is why your baby came early, how early, and how your other pregnancies went. Here's how clinics look at it.

It depends on why your baby came early and how early, and many women with a preterm birth in their history are reviewed case by case rather than ruled out automatically. A later full-term pregnancy, a single birth just a few weeks early or a clear one-time cause all work in your favor, while repeated or very early spontaneous preterm births make approval much less likely.

If your baby spent time in the NICU, I know this question can carry a lot of feeling. It's also one of the most practical questions a clinic will ask, because the pregnancy you carry as a surrogate is a new one, and everyone wants it to go to term. Here's how that review usually works.

Why programs ask about it

ASRM's recommendations for practices using gestational carriers say that, ideally, a carrier "should have had at least one, term, uncomplicated pregnancy." "Term" is the key word: a baby born at 37 weeks or later. Your past pregnancies are the best evidence anyone has about how your body handles pregnancy, which is why we've written a whole piece on why agencies require a prior uncomplicated pregnancy.

Preterm birth gets particular attention because it can repeat. ACOG describes a prior spontaneous preterm birth as one of the strongest risk factors for another one. IVF pregnancies also carry somewhat higher preterm risk than unassisted ones: a 2017 study in Fertility and Sterility followed women who had their own children naturally and later carried as surrogates, and found 10.7% of their surrogate births were preterm, compared with 3.1% of their own.

What "preterm" means, and why the cause matters

A baby born before 37 weeks is preterm, and births between 34 and 36 weeks are called late preterm. Doctors also separate preterm births into two kinds:

• Spontaneous. Labor started early, your water broke early, or your cervix opened too soon.
• Medically indicated. Your doctors chose to deliver early by induction or cesarean because of a problem such as preeclampsia, a placenta issue or concerns about the baby's growth.

The difference matters because each tends to repeat in its own way. In one large study, women with a prior spontaneous preterm birth were about 3.6 times as likely to have another one. When the early delivery was medically indicated, the condition behind it, such as preeclampsia, is what the clinic will mostly focus on. If that's your situation, our article on preeclampsia and gestational diabetes explains how those histories are reviewed.

What reviewers look at

Every clinic makes its own call, but the questions are fairly consistent.

How early

A single baby born at 36 weeks is viewed very differently from one born at 28 weeks. Risk of a repeat is higher the earlier the first preterm birth happened.

How many times

One preterm birth is a data point. Two or more spontaneous preterm births form a pattern, and most programs are cautious about that.

What happened next

A later full-term pregnancy helps a lot. In a study of women's third births, the chance of a preterm birth was about 13% for women whose first baby was preterm and second was term, compared with 42% when both earlier babies were preterm and 5% when both were term. A term birth after a preterm one lowers the risk, though not all the way to baseline.

Whether it was twins

Twins are often born early, so a preterm twin delivery is read differently from a preterm singleton. A Dutch study found spontaneous preterm birth in a later singleton pregnancy in 5.2% of women whose twins were born preterm, compared with 0.8% when the twins reached term. That's a meaningful increase, but lower than after a preterm singleton.

Cervical insufficiency or a cerclage

Cervical insufficiency means the cervix opens painlessly in the second trimester, without contractions. It's often treated with a cerclage, a stitch that helps hold the cervix closed. Because it can recur, clinics tend to look closely at this history, and some programs will decline it. The clinic's physician makes the decision after reading your records.

Timing and monitoring

Programs typically ask you to wait 6 to 12 months after a vaginal birth and 12 to 18 months after a cesarean before an embryo transfer. Short gaps between pregnancies are linked to higher preterm risk, and March of Dimes suggests waiting at least 18 months between giving birth and getting pregnant again, so your doctor may advise more time.

If you're accepted, your OB may watch your pregnancy a little more closely. ACOG recommends checking cervical length by ultrasound during the second trimester for women with a prior spontaneous preterm birth. ASRM strongly recommends single embryo transfer in all gestational carrier cycles, which greatly lowers the chance of twins and the higher preterm risk that comes with them.

Where Borne fits

Our questionnaire asks about each of your pregnancies, including how far along you were when you delivered. A preterm birth won't automatically end your application with us. If your history looks like one partner agencies typically consider, we'll talk it through on your screening call. If it's likely to be a no, we'll tell you honestly and explain why, so you're not left guessing.
