Fibroids and Trying to Conceive: What the Evidence Actually Says

What the evidence actually says about fibroids and fertility in 2026 — the types that matter, the ones that don’t, and the questions to bring to your next appointment.

The Reality About Fibroids and Fertility

If you’ve been told you have fibroids and you’re thinking about getting pregnant—or you’re struggling to conceive—you’ve probably felt that moment of panic. The questions pile up: Will I be able to have children? Do I need surgery before trying? Should I be worried?

Here’s what we need to tell you upfront: Having fibroids doesn’t automatically mean you can’t get pregnant. Most women with fibroids conceive without difficulty. But the type, size, and location of your fibroids matter enormously—and understanding these details is key to making the right decisions for your fertility journey.

The evidence from 2026 is more nuanced than ever. We’ve moved past the days of “you have fibroids, therefore you’re infertile.” Modern research shows us exactly which fibroids affect fertility and which ones don’t. That’s what this guide is about: giving you the real evidence so you can have informed conversations with your doctor.

Why This Matters Right Now

If you’re in your late 20s, 30s, or 40s and thinking about pregnancy, time matters. But so does accuracy. Getting clear information about your specific situation—not generic fibroid warnings—can help you make better decisions faster.

Some women need treatment before trying to conceive. Others are perfectly fine to try naturally. Still others might benefit from assisted reproductive technologies. The path forward depends entirely on your individual situation, and that’s what we’re going to walk you through.

Which Fibroids Actually Affect Conception

Not all fibroids are created equal when it comes to fertility. The location of your fibroid is far more important than its size.

Fibroids That Reduce Fertility (Evidence-Based)

Submucosal Fibroids (Inside the Uterine Cavity)

These are the fibroids that matter most for conception. Submucosal fibroids protrude into the uterine cavity where an embryo would implant. Think of it this way: imagine trying to hang a picture on a wall that has a large bump sticking out of it. That bump makes it harder for the picture to hang straight and secure.

Fertility impact: Intracavitary fibroids reduce conception rates by approximately 40-50% compared to women without fibroids
Pregnancy impact: They increase miscarriage risk and can cause complications during pregnancy
The evidence: Multiple prospective studies (strong evidence) show that removal of submucosal fibroids significantly improves conception rates and pregnancy outcomes
The good news: These fibroids are often treatable with minimally invasive procedures like hysteroscopic myomectomy (fibroid removal through the vagina and cervix—no incisions)

Intramural Fibroids Distorting the Cavity

Some fibroids grow within the uterine muscle (intramural) but bulge significantly into the uterine cavity. These also affect fertility, though less severely than purely submucosal fibroids.

Fertility impact: Moderate reduction in conception rates, particularly if they distort the cavity significantly
What matters: How much they protrude into the cavity. Small intramural fibroids that barely touch the cavity have minimal impact on fertility
Treatment: Your doctor will use imaging to determine if removal is recommended

Fibroids That Don’t Significantly Affect Fertility

Intramural Fibroids (Within the Muscle, Not Distorting the Cavity)

These fibroids grow in the uterine muscle wall but don’t significantly bulge into the cavity where an embryo implants.

Fertility impact: Minimal to none if they’re not distorting the cavity
The evidence: Research shows that intramural fibroids ≤4cm in size that don’t distort the cavity have no significant impact on conception rates
Pregnancy impact: Generally safe, though very large intramural fibroids may cause pregnancy complications like preterm labor
Treatment recommendation: Usually NOT recommended for fertility purposes alone

Subserosal Fibroids (On the Outside of the Uterus)

These fibroids grow on the outer surface of the uterus, pointing outward.

Fertility impact: No significant impact on conception
Why: They’re not in contact with the uterine cavity where pregnancy occurs
The evidence: Strong evidence confirms that subserosal fibroids don’t affect conception rates
Exception: If they’re very large and causing pain or pressure, you might want them removed for quality of life reasons—but not for fertility

What Are Your Real Odds?

This is the question every woman wants answered: “Can I get pregnant?”

The honest answer is: It depends on your fibroids. But here’s what the evidence tells us:

If You Have Only Intramural or Subserosal Fibroids (Not Distorting the Cavity)

Conception rate: 80-90% of women will conceive naturally within 12 months of trying (same as women without fibroids)
Miscarriage rate: Similar to general population (15-20%)
Bottom line: You have essentially the same fertility as women without fibroids

If You Have Submucosal or Cavity-Distorting Fibroids

Conception rate (untreated): 40-50% reduction in conception rates
What this means: If you would normally have a 80% chance of conception per year, with significant submucosal fibroids that drops to approximately 40-50%
Miscarriage rate: Increased to 25-40% (compared to 15-20% general population)
After treatment: Removal of submucosal fibroids restores conception rates to near-normal levels

The Fibroid Size Question

One of the most common questions: “Does the size of my fibroid matter?”

For fertility specifically: Size matters far less than location. A small submucosal fibroid that protrudes into the cavity may reduce fertility more than a large intramural fibroid that doesn’t distort anything.

For pregnancy: Very large intramural fibroids (>4cm) are associated with higher rates of preterm labor and other pregnancy complications, even if they didn’t affect conception.

Getting Pregnant with Fibroids: The Practical Path

Step 1: Get Accurate Imaging

Before making any decisions, you need to know exactly where your fibroids are and whether they distort the uterine cavity.

Best imaging options:

Transvaginal ultrasound: The gold standard for assessing cavity distortion. This provides detailed images of how fibroids affect the uterine cavity
MRI: Best for understanding your complete fibroid picture, especially if you have multiple fibroids. Gives the clearest image of fibroid locations and their relationship to the cavity
Saline sonohysterography: Fills the uterus with saline to show exactly how much fibroids protrude into the cavity

What to ask your doctor: “Does my fibroid distort my uterine cavity? By how much?” This single question determines much of what comes next.

Step 2: Determine if You Need Treatment

You likely need treatment if:

You have submucosal fibroids protruding significantly into the cavity
You have intramural fibroids that distort the cavity substantially
You’ve been trying to conceive for 6-12 months without success and imaging shows cavity distortion
You’re about to pursue IVF and your fibroids distort the cavity (evidence shows they reduce IVF success rates)

You likely don’t need treatment if:

Your fibroids are intramural or subserosal and don’t distort the cavity
You’re having no trouble conceiving naturally
Your only symptom is occasional spotting and you’re planning to try to get pregnant

Step 3: Choose Your Treatment Path (If Needed)

Hysteroscopic Myomectomy (Minimally Invasive)

Best for: Submucosal fibroids and intramural fibroids that significantly distort the cavity
How it works: A thin telescope is inserted through the cervix into the uterus. The surgeon uses specialized instruments to remove or ablate the fibroid from inside
Recovery: Outpatient procedure, go home the same day, back to normal activities in 1-2 weeks
Success for fertility: 60-80% of women conceive within 12 months after procedure
Pregnancy outcomes: Significantly improved after successful myomectomy
Evidence level: Strong evidence supports this approach

Laparoscopic or Open Myomectomy (More Invasive)

Best for: Large intramural fibroids, multiple fibroids, or fibroids not accessible hysteroscopically
How it works: Surgeon accesses the uterus from outside and removes the fibroid from the muscle
Recovery: 4-6 weeks for laparoscopic, 6-8 weeks for open surgery
Pregnancy consideration: After myomectomy, you typically need to wait 3-6 months before trying to conceive to allow the uterus to heal
Important note: If the fibroid was very large or deep, you may need a cesarean section for future pregnancies
Success for fertility: 50-70% of women conceive within 2 years

Medical Management (Temporary Symptom Relief)

Options: GnRH agonists, progestin-only methods
Purpose: Reduce symptoms and fibroid size, not a permanent solution
For fertility: Usually used temporarily before surgery to improve surgical conditions, not as a standalone fertility treatment
Duration: Typically 3-6 months maximum (longer use causes bone loss)

Uterine Fibroid Embolization (UFE)

How it works: Radiologist blocks blood flow to fibroids, causing them to shrink
For fertility: More controversial than myomectomy. Some women conceive successfully after UFE, but it’s associated with higher miscarriage rates and potential ovarian reserve impact
Use carefully: If fertility is your priority, myomectomy is generally preferred
Evidence level: Moderate evidence; not first-line for fertility preservation

Carrying a Pregnancy with Fibroids: What to Expect

Pregnancy Complications Associated with Fibroids

If you’re pregnant with fibroids, what should you know?

Miscarriage Risk

Submucosal fibroids: Increase miscarriage risk to approximately 25-40% (versus 15-20% baseline)
Cavity-distorting intramural fibroids: Moderate increase in miscarriage risk
Non-cavity-distorting intramural fibroids: Minimal increased risk
Subserosal fibroids: No increased miscarriage risk

Preterm Labor

Risk increases with: Large intramural fibroids (>4cm), multiple fibroids, fibroids located low in the uterus
Mechanism: Fibroids may cause uterine irritability and premature contractions
Management: Close monitoring in third trimester, possible bed rest or medications to prevent preterm labor

Intrauterine Growth Restriction (IUGR)

Associated with: Large fibroids that reduce blood flow to growing parts of the placenta
Management: More frequent ultrasounds to monitor baby’s growth

Placental Abruption

Rare but serious: Occurs more frequently with large fibroids
Requires: Immediate medical attention; typically leads to emergency delivery

Fibroid “Degeneration” During Pregnancy

What happens: Fibroids can outgrow their blood supply during pregnancy, causing pain, fever, and nausea
Frequency: Occurs in 1-3% of pregnancies with fibroids
Management: Pain control, rest, and monitoring; rarely requires surgery during pregnancy
Outcome: Usually resolves within 1-2 weeks

Delivery Considerations

Vaginal Delivery vs. Cesarean Section

Vaginal delivery is usually possible unless fibroids are blocking the birth canal or other complications exist
Cesarean section may be necessary if: Large fibroids are low in the uterus and block the cervix or birth canal, fibroids obstruct vaginal delivery
Submucosal fibroids that were treated: Usually don’t require cesarean section

Retained Placenta Risk

Fibroids can increase: The risk that the placenta doesn’t detach completely after delivery
Management: Your doctor will be prepared with appropriate interventions

Your Pregnancy Plan with Fibroids

What your care should include:

Clear documentation of your fibroid characteristics at the start of pregnancy
Higher-level ultrasound monitoring (more frequent than standard care)
Discussion of delivery plans based on fibroid location and size
Education about warning signs (severe pain, bleeding, preterm labor symptoms)
Coordination between your OB and a maternal-fetal medicine specialist if fibroids are significant

Treatment Options Decision Tree

Scenario 1: Trying to Conceive, Submucosal Fibroids Present

Recommendation: Hysteroscopic myomectomy before attempting conception

Timeline: Procedure first, wait 1-2 months for healing, then begin trying to conceive

Success: 60-80% conception rate within 12 months post-procedure

Scenario 2: Trying to Conceive, Intramural Fibroids (Not Distorting Cavity)

Recommendation: Proceed with attempts to conceive; treatment not necessary

Timeline: Try naturally for 6-12 months before reconsidering

If unsuccessful: Pursue fertility testing (ovulation studies, partner semen analysis, tubes testing) as fibroids are likely not the issue

Scenario 3: Trying to Conceive, Unsuccessful After 12 Months, Submucosal Fibroids

Recommendation: Hysteroscopic myomectomy if not yet done

Consider also: Fertility evaluation for other potential causes (ovulation, tube patency, partner factor)

Scenario 4: Ready for IVF, Fibroids Present

If cavity-distorting fibroids: Remove before IVF (improves success rates)

If non-cavity-distorting: Usually can proceed with IVF without fibroid treatment

Questions to Bring to Your Doctor

Come prepared. Here are the exact questions that will help you understand your situation:

“Where exactly are my fibroids located?” (Ask for specifics: submucosal, intramural, subserosal)
“Do my fibroids distort my uterine cavity?” (This is THE key question for fertility)
“How much do they protrude into the cavity?” (Quantify the distortion)
“What is the evidence that treatment would improve my fertility?” (Insist on evidence-based answers)
“What are my options if I want to get pregnant?” (Get all options, not just surgery)
“What is the success rate for my specific situation?” (Personalize the statistics)
“If I need surgery, what type and why?” (Hysteroscopic vs. laparoscopic vs. open)
“How long do I need to wait after treatment before trying to conceive?” (Confirm timeline)
“What are the risks to a future pregnancy?” (Be realistic)
“Should I consider IVF instead of trying naturally?” (Discuss all paths)
“How often will I be monitored during pregnancy?” (Know your care plan)
“Will I definitely need a cesarean section?” (Usually no, but depends on location)

Your Next Steps

This Week

If you don’t already have clear imaging results showing exactly where your fibroids are and whether they distort your cavity, schedule that imaging now. Don’t proceed without clarity.

Before Your Doctor Appointment

Gather all your imaging reports (ultrasounds, MRI, hysteroscopy)
Document when your fibroids were diagnosed and any growth you’ve noticed
Write down your timeline: when are you hoping to get pregnant?
Note any symptoms (heavy bleeding, pain, pressure) you’re experiencing

During Your Appointment

Bring this guide. Use the questions above. Ask for clear answers. If your doctor says you “can’t get pregnant” or “definitely need surgery,” ask why. The evidence is usually more nuanced than that.

After Your Appointment

Ask for a written summary of your fibroid characteristics
Get specific recommendations in writing
Request copies of all imaging
Ask about second opinions if you’re unsure

If You’re Proceeding with Treatment

Get clear information about recovery timelines
Understand when you can resume trying to conceive
Know what to watch for post-treatment
Schedule follow-up imaging if recommended

If You’re Proceeding Natural

Know how long to try before fertility testing (usually 12 months, or 6 months if over 35)
Understand what other testing might be needed
Know your doctor’s criteria for when fibroids become a concern during your pregnancy journey

The Bottom Line

Here’s what we want you to know:

Most women with fibroids can get pregnant. The location and size of your specific fibroids determine whether they’re a fertility issue.

Submucosal fibroids affect fertility. Intramural fibroids usually don’t (unless they distort the cavity significantly). Subserosal fibroids don’t affect fertility at all.

If you need treatment, excellent options exist—and they work. Hysteroscopic myomectomy is minimally invasive and has strong success rates.

You have time to make thoughtful decisions. Don’t rush into surgery you don’t need, but don’t delay treatment that would help either.

Your specific situation matters more than general fibroid statistics. Get clear imaging. Ask specific questions. Make informed decisions based on your actual fibroids, not generic fibroid warnings.

Pregnancy with fibroids is usually safe, but requires attentive care, especially if you have cavity-distorting fibroids.

You can have the family you want. Fibroids don’t have to stop that. But understanding your specific situation is key.
