- The risk of premature birth is higher when you are carrying multiple fetuses, which increases an infant's chances of having severe health problems.
- This procedure to reduce the number of fetuses has a risk of miscarriage of the remaining fetuses.
- Early genetic testing (chorionic villus sampling) and fetal ultrasound can help you find out if any of the fetuses has a problem. This information may help you decide about reducing the number of fetuses.

FAQs
Multifetal pregnancy reduction is a procedure to reduce the number of fetuses in a pregnancy—usually from three, four, or five fetuses to two. This may help the two fetuses survive and help you have a healthy pregnancy.
This procedure is most often done early in the first trimester or early in the second trimester. It can be done after genetic testing to find out if the fetuses have any problems.
It's usually done through the belly. Using ultrasound as a guide, the doctor puts a needle into the uterus to the selected fetus or the umbilical cord. The doctor injects the fetus or the cord with a medicine that stops the heart.
The dead embryo or fetus is absorbed by the mother's body. This is similar to what happens with vanishing twin syndrome.
Reduced risk for mother. The procedure reduces the mother's risk of problems. These risks include gestational diabetes, preeclampsia, and anemia. These risks increase with each added fetus.
Reduced risk for infants. The procedure may improve your chances of carrying your pregnancy longer and your chances of delivering one or more healthy babies.
Carrying triplets or more increases the risk of miscarriage, stillbirth, premature birth, and disability.
Reduced stress related to infant care. Caring for three or more babies can be stressful, especially if any of them has health problems.
The risks of reducing the number of fetuses include:
- Miscarriage of the other fetuses. The miscarriage rate is lower if there are fewer fetuses at the start of the procedure.
- Emotional risks for you, especially if the pregnancy miscarries.
Some couples choose to implant fewer embryos to reduce the chance of a pregnancy of triplets or more, rather than consider having this procedure.

Have fetal reductionHave fetal reduction- You will have an ultrasound test to make sure that the fetus or fetuses to be reduced are in their own amniotic sac. Separate sacs reduce the chance of miscarriage. A different procedure may be done if the fetuses are in the same sac.
- It's done in the doctor's office. It takes only a few minutes.
- You will be watched at the doctor's office afterward to make sure that the remaining fetuses are doing well.
- Having fewer fetuses reduces the risk of miscarriage, stillbirth, premature birth, and disability.
- You have a lower chance of problems in your pregnancy, such as gestational diabetes, preeclampsia, or anemia. These risks increase with each added fetus.
- It may reduce the stress related to caring for more infants.
- You could miscarry the remaining fetuses.
- Some parents have grief, guilt, and depression about reducing the number of fetuses.
Carry three or more fetusesCarry three or more fetuses- You will see your doctor more often during your pregnancy.
- You will likely see a perinatologist. This doctor takes care of women who may have a problem in their pregnancy.
- You may have more tests than you would in a pregnancy with one fetus.
- You may avoid the emotional stress that some people feel about reducing the number of fetuses.
- You have a lower risk of infection.
- Carrying triplets or more increases the risk of miscarriage, stillbirth, premature birth, and disability.
- Multiple pregnancy increases the mother's risk of problems such as gestational diabetes, preeclampsia, and anemia. These risks increase with each added fetus.
When my husband and I learned we were expecting three babies, we were thrilled. But along with that news we heard about the risks for them and me. I'm already at risk for pregnancy problems, since I've had gestational diabetes before. So we decided to have a multifetal pregnancy reduction. What convinced me was the knowledge that the miscarriage rate is higher for triplet pregnancy than it is for the twins after the procedure. And it went well for us. We took the risk, and the babies and I are doing well.
Because of my age, our fertility doctor encouraged us to have four embryos transferred for my in vitro. We were surprised that all of them took and were worried about the risks. After talking for a few days about having a multifetal pregnancy reduction, my husband and I decided not to have one. We were more comfortable with letting nature take its course. And it did—by the second trimester, two were gone, and I was carrying twins.
I just couldn't bring myself to have a multifetal pregnancy reduction, even though my doctor told me that my pregnancy was high-risk. I'll never know whether it would have gone better if I'd had the procedure, but trying to carry the four babies didn't go well. One died after birth, and now we have the challenge of raising triplets, one of which is disabled.

5. What else do you need to make your decision?
Check the facts
1. Does a fetal reduction lower the chance that your remaining baby or babies will have a disability?
You're right. A fetal reduction lowers the chance that your remaining baby or babies will have a disability. It also lowers the chance of a fetus or infant dying or being ill.
2. Is your risk of having a miscarriage higher with a fetal reduction than it is with having triplets or more?
You're right. The risk of miscarriage is higher from having triplets or more than it is from having a fetal reduction.
3. Do both choices have emotional side effects?
You're right. Either choice can be emotional and complex. You may feel guilty if you reduce the number of fetuses. But you may have a hard time raising multiples.
Decide what's next
1. Do you understand the options available to you?
2. Are you clear about which benefits and side effects matter most to you?
3. Do you have enough support and advice from others to make a choice?
