Doctors turn a breech baby using a hands-on procedure called external cephalic version, or ECV. During this procedure, a doctor applies firm, sustained pressure to your abdomen to manually guide the baby from a bottom-down position into a head-down position. It’s typically performed around 36 to 37 weeks of pregnancy, and it succeeds roughly 50 to 60 percent of the time.
What Happens During the Procedure
ECV is always performed on a labor and delivery unit, not in a regular exam room. An operating room needs to be available in case an emergency cesarean becomes necessary. Before anyone touches your belly, a bedside ultrasound checks the baby’s exact position, the amount of amniotic fluid, the location of the placenta, and the shape of the uterine cavity. All of this helps the doctor judge whether the procedure is safe to attempt and how likely it is to work.
You’ll also have fetal heart rate monitoring before the procedure starts, establishing a baseline for the baby’s condition. In many cases, you’ll receive medication through an IV to temporarily relax the uterine muscles, which makes the uterus softer and gives the baby more room to move. Once everything looks good, the doctor places both hands on your abdomen and slowly pushes the baby in a forward roll or backward somersault, depending on which direction is most favorable. The goal is to tuck the baby’s chin and create a compact shape that rotates more easily. The whole manipulation typically takes just a few minutes, though some doctors will make more than one attempt if the first doesn’t work.
The pressure can feel intense. Some women describe it as uncomfortable but manageable, while others find it genuinely painful. If you’re in significant distress, or if the baby’s heart rate drops, the doctor will stop immediately.
Who Can and Can’t Have an ECV
Not every breech pregnancy is a candidate. According to the American College of Obstetricians and Gynecologists, ECV will not be attempted if you are carrying more than one baby, if there are concerns about the baby’s health, if the placenta covers the cervical opening (placenta previa), if the placenta has already started separating from the uterine wall, or if you have certain structural abnormalities of the uterus. Low amniotic fluid levels also make the procedure riskier, because the baby has less room to rotate safely.
Your doctor will weigh all of these factors using the pre-procedure ultrasound. If anything raises a red flag, the attempt is typically called off in favor of planning a cesarean delivery.
Risks and What Could Go Wrong
ECV is considered safe overall, but it carries real risks, which is why it’s done in a hospital setting. Placental abruption, umbilical cord prolapse, rupture of membranes, and fetal distress each occur in fewer than 1 percent of cases. In one study published in the European Journal of Obstetrics and Gynecology, 16 percent of patients who underwent ECV ended up needing an emergency cesarean section. That number reflects both immediate complications and cases where the baby flipped back to breech afterward.
The baby’s heart rate is monitored continuously during and after the procedure. If the heart rate drops and doesn’t recover quickly, the team can move to a cesarean within minutes. This is the primary reason ECV is never done in an outpatient clinic.
What Recovery Looks Like
If the version succeeds and the baby’s heart rate looks normal, you’ll typically be monitored for 30 minutes to an hour afterward and then sent home. There’s no bed rest required, but you should contact your doctor or midwife right away if you experience abdominal pain, contractions, vaginal bleeding, fluid leaking from the vagina, or a noticeable decrease in the baby’s movement. These could signal complications that developed after you left the hospital.
One frustrating possibility: the baby can flip back to breech after a successful ECV. This happens in a small percentage of cases, and there’s no reliable way to prevent it. Some doctors will attempt the procedure a second time if the baby reverts.
Alternative Approaches
Some women explore other methods before or alongside ECV, though the evidence behind them is mixed.
Moxibustion is a traditional Chinese medicine technique that involves burning an herb near the outside edge of the fifth toe. A Cochrane review of multiple trials found moderate-certainty evidence that moxibustion combined with standard care probably reduces the chance of a baby remaining breech at birth by about 13 percent compared to standard care alone. However, it did not clearly reduce the cesarean section rate.
The Webster technique is a chiropractic adjustment aimed at balancing the pelvis. It involves adjusting the sacrum and releasing tension in the abdominal muscles. Chiropractor-reported success rates have ranged from 82 to 97 percent, but these figures come from surveys and case series rather than controlled clinical trials, so they should be interpreted cautiously.
Neither moxibustion nor chiropractic care is a substitute for ECV if your doctor recommends it. They may be worth discussing as complementary options, particularly in the weeks before an ECV is scheduled, but the manual version remains the only procedure with strong enough evidence to be routinely offered in obstetric care.
Why Timing Matters
ECV is typically scheduled between 36 and 37 weeks for a first pregnancy. Earlier than that, the baby may flip back on its own (and many breech babies do before 36 weeks). Later than that, the baby is larger and more tightly wedged into the pelvis, making the procedure harder and less likely to succeed. The amount of amniotic fluid also tends to decrease in the final weeks, further reducing the room available for rotation. If your baby is still breech at your 36-week appointment, that’s the window to have this conversation with your provider.
