Whether fibroids affect your labor or delivery depends largely on their size, number, and location in the uterus. Most women can get pregnant with fibroids and successfully and deliver a healthy baby, although there’s a slightly heightened risk of preterm labor and cesarean delivery associated with fibroids. According to the NCBI study, approximately 10% to 30% of women with fibroids may experience pregnancy-related complications, typically of mild severity. This page covers what the research says about fibroid complications during delivery, what increases C-section risk, whether a hysterectomy is ever necessary, and what treatment options may be available once you have recovered from childbirth.
Does Fibroid Size and Location Affect Labor and Delivery?
Not all fibroids carry the same level of risk during labor and delivery. Two factors matter most: size and location within the uterus.
How Fibroid Size Affects Delivery
Fibroids larger than approximately 5 centimeters (about two inches) in diameter are more likely to affect how labor progresses. Larger fibroids can occupy space within the uterine cavity, potentially interfering with the baby’s positioning or the mechanics of labor. Smaller fibroids, particularly those that do not affect the uterine cavity, are less likely to cause delivery complications.
Size alone does not determine outcome. A small fibroid positioned near the cervix can create more difficulty during labor than a much larger fibroid located on the outer wall of the uterus.
How Fibroid Location Affects Delivery
Where a fibroid sits within the uterus often matters more than its size. Fibroids are classified by location:
| Fibroid Type | Location | Potential Delivery Impact |
|---|---|---|
| Submucosal | Inside the uterine cavity | Highest risk: may distort the cavity, interfere with contractions, and increase C-section likelihood |
| Intramural | Within the uterine wall | Moderate risk: depends on size and whether the uterine cavity is distorted |
| Subserosal | Outer wall of the uterus | Lower risk: least likely to directly affect labor or delivery |
Fibroids located in the lower uterine segment, the area of the uterus closest to the cervix, deserve particular attention. Research published in the International Journal of Gynecology and Obstetrics found that the cesarean delivery rate for women with lower-segment fibroids was 86%, compared to 40% for women whose fibroids were located in the body of the uterus.² This difference reflects how much the position of a fibroid, not just its presence, shapes the delivery picture.
If your fibroids are in a position that may affect delivery, your care team may refer you to a maternal-fetal medicine specialist. This specialist works alongside your OB-GYN to use targeted ultrasound monitoring throughout pregnancy and help build a delivery plan based on your specific fibroid size, type, and location.

Giving Birth With Fibroids: Vaginal Delivery vs. C-Section
Many women with fibroids deliver vaginally without complications. Whether vaginal delivery is possible depends on your individual fibroid picture, and that assessment happens throughout your pregnancy, not just at the time of delivery.
When Vaginal Delivery May Still Be Possible
If your fibroids are small, located on the outer wall of the uterus, or not positioned near the birth canal, your care team may plan for a vaginal delivery. Your provider will monitor fibroid size and location using ultrasound through each trimester and reassess as your due date approaches. Even when a fibroid looked like a concern earlier in pregnancy, uterine expansion sometimes shifts its position enough that vaginal delivery remains possible.
Open communication with your OB-GYN or maternal-fetal medicine specialist throughout your pregnancy gives your care team the information they need to build the safest delivery plan for you.
Fibroids and C-Section: What to Expect
Certain fibroid characteristics meaningfully increase the likelihood of cesarean delivery. A 2026 meta-analysis found that women with fibroids have approximately two to two and a half times the odds of cesarean delivery compared to women without fibroids.² That risk increases further when fibroids are:
- Located in the lower uterine segment or near the cervix, where they can physically block the baby’s path through the birth canal
- Large enough to interfere with uterine contractions, slowing or stalling labor progress (a condition called labor dystocia)
- Contributing to malpresentation, meaning the baby cannot move into the standard head-down position for delivery
A C-section, when recommended, is a planned and carefully managed delivery option. It is not a sign that something has gone wrong. For many women with fibroids, it is the safest path forward when fibroid size or position makes vaginal delivery difficult.
Other Pregnancy and Delivery Complications to Know About
Most women with fibroids have uncomplicated pregnancies. The following complications are less common, but your care team will monitor for them, particularly if you have large or multiple fibroids.
Placental Abruption and Placenta Previa
Placental abruption occurs when the placenta separates from the uterine wall before delivery. Research indicates women with fibroids have approximately 2.6 times the odds of placental abruption compared to women without fibroids.² Placenta previa, when the placenta implants over or near the cervix, is also more common in women with fibroids, with roughly twice the odds compared to women without them.²
Preterm Labor and Fibroid Degeneration
Fibroid degeneration occurs when a fibroid outgrows its blood supply and begins to break down. This process can trigger uterine contractions and, in some cases, contribute to early labor. Fibroids located near the cervix may also place pressure that increases preterm delivery risk. If you experience significant pelvic pain or uterine cramping during pregnancy, contact your healthcare provider promptly.
Malpresentation and Labor Dystocia
Malpresentation occurs when the baby is positioned in a way that makes vaginal delivery more difficult, such as a breech position. Large fibroids that limit space inside the uterus can contribute to this. Labor dystocia refers to a slowing or stalling of labor progress due to fibroid-related obstruction or interference with uterine contractions.
Postpartum Hemorrhage
Heavier-than-normal bleeding after delivery is more common in women with fibroids. Research indicates that women with fibroids have roughly three times the odds of postpartum hemorrhage compared to women without them.² Modern obstetric units are equipped with protocols to monitor and manage this risk, and your care team will factor fibroid-related hemorrhage risk into your delivery plan if indicated.

Will I Need a Hysterectomy if I Have Problems During Delivery?
This is one of the most common concerns women with fibroids bring to their care teams, and it deserves a direct answer: a hysterectomy is rarely necessary due to fibroid-related delivery complications alone.
Most fibroid-related delivery challenges are managed through planned cesarean delivery, medication to support uterine contractions, or close postpartum monitoring. Hysterectomy during or immediately after delivery is reserved for severe, uncontrolled hemorrhage or other obstetric emergencies that are uncommon and not unique to fibroid patients.
What significantly reduces the risk of emergency intervention is preparation. Women who know their fibroid type and location before delivery, work with a care team that includes a maternal-fetal medicine specialist when indicated, and have a documented delivery plan in place are in the strongest possible position going into labor.
Fibroids do not automatically put any woman on a path toward losing her uterus. The evidence supports that most women with fibroids, including those who require a C-section, recover fully from delivery and go on to explore treatment options that preserve the uterus entirely.
What Happens to Fibroids After Giving Birth?
Fibroids often change after delivery. As hormone levels drop and the uterus contracts back to its pre-pregnancy size, fibroids frequently shrink. Research published in 2026 found that fibroids decrease in volume by more than 50% within three to six months after delivery in approximately 70% of women who have a live birth.²
This natural shrinkage does not always eliminate fibroid-related symptoms permanently. Symptoms such as heavy menstrual bleeding, pelvic pain, pressure, and bloating that were present before or during pregnancy may return as hormone levels normalize in the weeks and months after delivery.
If fibroid symptoms return or worsen after your postpartum recovery, treatment options are available. Tracking your fibroid symptoms and how they compare to what you experienced before pregnancy can help you have a more productive conversation with a fibroid specialist.
Postpartum Fibroid Treatment: Your Options After Recovery
Pregnancy is not the time to treat fibroids. The increased blood supply to the uterus during pregnancy makes fibroid intervention risky for both mother and baby. Treatment is always deferred until after full postpartum recovery.
Once you have recovered from childbirth, typically after your postpartum checkup confirms you are ready, addressing fibroid symptoms becomes possible. If you experienced heavy bleeding, pelvic pain, or pressure before or during your pregnancy, those symptoms may return and, for some women, intensify after delivery.
Uterine Fibroid Embolization (UFE) After Delivery
Uterine fibroid embolization (UFE) is a minimally invasive, non-surgical outpatient procedure that works by reducing the blood supply to fibroids, causing them to shrink over time. It is performed by a fibroid specialist and does not require general anesthesia or an overnight hospital stay. Most patients return to normal activities within one to two weeks.³
UFE preserves the uterus. For women who experienced delivery complications related to fibroids and are thinking about their options going forward, this matters. A uterus-preserving approach means the uterus remains intact, which your fibroid specialist can discuss further in the context of your individual health picture and future family goals.
UFE is not performed during pregnancy or while breastfeeding. A consultation with a fibroid specialist after your postpartum recovery is the appropriate first step to understand whether UFE may be right for you.
USA Fibroid Centers offers UFE at accredited outpatient centers nationwide. A fibroid specialist can review your imaging, discuss your symptoms, and help you understand what postpartum treatment may look like for your specific situation.
Talk to a Fibroid Specialist After Your Delivery
Labor and delivery with fibroids is a topic that deserves honest, clear answers. Most women with fibroids deliver healthy babies. Most fibroid-related delivery challenges are addressed through preparation and planning. And after recovery, fibroid symptoms do not have to become the new normal.
A fibroid specialist can review your situation, explain your options, and help you understand whether a minimally invasive, uterus-preserving approach like UFE may be appropriate for you. USA Fibroid Centers has accredited outpatient locations nationwide, and scheduling online takes minutes.
