Imagine trying for months, or even years, to get pregnant, only to be told that a small, non-cancerous growth you’ve never even heard of might be standing in your way. That’s the reality for many women dealing with uterine fibroids.
If you’ve recently been diagnosed or are simply exploring the topic, you’re probably asking one key question: Can uterine fibroids actually cause infertility?
The short answer is: sometimes, yes, but not always.
In this detailed guide, we’ll break it all down in simple, easy-to-understand language so you can feel informed, empowered, and prepared to take the next step.

So, Can Fibroids Cause Infertility?
Let’s talk about what many women are really worried about: Do fibroids mean I won’t be able to get pregnant?
The answer isn’t as scary as it might seem.
Fibroids can play a role in infertility, but they are not always the main reason. In fact, studies show that fibroids are present in about 5–10% of women who are experiencing difficulty getting pregnant. However, they are the only cause of infertility in a much smaller number of cases, roughly 2–3%.
Across the United States, fibroids are estimated to contribute to infertility in about 5–10% of cases overall. What this really means is that while fibroids can sometimes interfere with pregnancy, they are just one piece of a much larger puzzle.
For many women, fibroids don’t prevent pregnancy at all. Plenty of women with fibroids go on to conceive naturally and have healthy pregnancies, especially when the fibroids are small or located in areas that don’t affect the uterus directly.
So if you’ve been diagnosed with fibroids, it’s important not to jump to conclusions. Instead, think of it as something that needs to be evaluated in context, along with other factors like age, overall reproductive health, and where exactly the fibroids are located.
The key takeaway?
Fibroids can make pregnancy more challenging in some cases, but for most women, they don’t make it impossible.
How Fibroids Can Affect Fertility
Fibroids don’t affect fertility in the same way for every woman. Their impact really depends on where they are located, how large they are, and how many are present. Some women may have fibroids and experience no fertility issues at all, while others may face challenges when trying to conceive.
To understand this better, it helps to look at the different ways fibroids can interfere with pregnancy and fertility:
1. Blocking the Path to Pregnancy
In some cases, fibroids grow in a position where they physically block the normal reproductive pathway. If a fibroid presses against or obstructs the fallopian tubes or the cervix, it can make it harder for sperm to reach the egg. Even if ovulation is normal, this “blocked pathway” can reduce the chances of fertilization happening naturally.
2. Changing the Shape of the Uterus
The uterus is where a fertilized egg needs to implant and grow. When fibroids develop inside or push into the uterine cavity, they can change the natural shape of the uterus. This distortion can make it difficult for an embryo to properly attach to the uterine wall, which is a critical step in early pregnancy.
3. Affecting the Uterine Lining
The uterine lining (also called the endometrium) plays a key role in supporting a pregnancy. Certain types of fibroids can interfere with this lining by making it thinner, uneven, or less receptive. When this happens, even a fertilized egg may struggle to implant successfully, which can lower the chances of pregnancy.
4. Reducing Blood Flow
A healthy pregnancy depends on strong blood flow to the uterus, as it provides oxygen and nutrients needed for early development. Fibroids can sometimes reduce or redirect blood supply, which may affect the environment needed for implantation and early fetal growth.
5. Increasing the Risk of Miscarriage
Even when conception does occur, fibroids can sometimes increase the risk of pregnancy complications. Depending on their size and location, they may contribute to a higher chance of miscarriage, preterm labor, or other pregnancy-related issues. This is especially true for fibroids that significantly alter the shape or function of the uterus.
Types of Fibroids and Their Impact on Fertility
Not all fibroids affect fertility in the same way. In fact, where a fibroid grows is often more important than how big it is when it comes to pregnancy outcomes. Understanding the different types can help make sense of why some women experience fertility issues while others do not.
Submucosal Fibroids (Inside the Uterine Cavity)
These fibroids grow just underneath the lining of the uterus, often pushing into the uterine cavity itself. Because this is the exact space where a fertilized egg needs to implant, submucosal fibroids are considered the most likely to affect fertility.
They can interfere with implantation, disrupt the uterine lining, and make it more difficult for an embryo to attach and grow. Even small fibroids in this location can sometimes have a significant impact on pregnancy chances.
Intramural Fibroids (Within the Uterine Wall)
Intramural fibroids develop within the muscular wall of the uterus. Their effect on fertility can vary depending on their size and whether they begin to distort the shape of the uterus.
In some cases, these fibroids may not cause any issues at all. However, when they grow larger or multiple fibroids are present, they can alter the structure of the uterus, which may make it more difficult for implantation to occur or for a pregnancy to develop normally.
Subserosal Fibroids (Outside the Uterus)
Subserosal fibroids grow on the outer surface of the uterus. Because they are located away from the uterine cavity, they typically do not interfere with implantation or fertility.
Most women with subserosal fibroids do not experience problems with conception, unless the fibroids become very large and begin to put pressure on nearby organs.
Why Location Matters More Than Size
While it might seem logical that larger fibroids would always cause more problems, research shows that location plays a much bigger role than size when it comes to fertility. A small fibroid inside the uterine cavity may have a greater impact than a much larger fibroid growing on the outside of the uterus.
This is why a detailed evaluation is so important, understanding exactly where fibroids are located helps doctors determine whether they could be affecting fertility and what treatment approach might be most effective.
Signs Fibroids Might Be Affecting Your Fertility
You might not immediately connect fibroids with fertility problems, especially because many women have them without noticeable symptoms. However, in some cases, fibroids can quietly affect reproductive health. That’s why it’s important to pay attention to your body and consider seeing a specialist if certain signs appear.
If you’ve been trying to conceive or noticing unusual changes in your menstrual cycle or pelvic health, it may be time to get evaluated. Early assessment can help identify whether fibroids—or another underlying issue, could be affecting your fertility.
You should consider speaking with a specialist if you experience:
- Difficulty getting pregnant after 6–12 months of regular, unprotected intercourse, especially if you are under 35
- Repeated miscarriages, which may suggest an issue with implantation or uterine structure
- Very heavy or prolonged periods, sometimes with clots or significant discomfort
- Pelvic pressure or pain, including a feeling of fullness or heaviness in the lower abdomen
These symptoms don’t automatically mean fibroids are causing infertility, but they are important warning signs that something may be affecting your reproductive health. A proper evaluation can help determine the exact cause and guide you toward the right treatment options, improving your chances of a healthy pregnancy.
Can Treating Fibroids Improve Fertility?
Yes, in many cases, treating fibroids can improve your chances of getting pregnant.
Treatment options depend on your symptoms, age, and future pregnancy plans. Common approaches include:
- Medication to control symptoms
- Minimally invasive procedures
- Myomectomy (surgical removal of fibroids)
Studies suggest that removing fibroids in certain cases can significantly improve pregnancy rates, especially when fibroids are inside the uterine cavity.
Why Early Evaluation Matters
One of the biggest mistakes women make is assuming fibroids are always harmless. While many are, some can silently affect fertility.
That’s why early evaluation is key, especially if you’re planning to conceive.

Final Thoughts: What You Should Remember
Fibroids can feel overwhelming at first, especially when you start connecting them with fertility concerns. But the most important thing to understand is that they are very common and often harmless, and many women live with them without even knowing they exist.
While fibroids can sometimes affect fertility, this is not always the case. In fact, their impact depends on a few key factors, mainly where they are located, how large they are, and how many are present. These details matter far more than the diagnosis itself when it comes to understanding how they may influence your chances of getting pregnant.
It’s also important to remember that many women with fibroids go on to conceive successfully and have healthy pregnancies, especially with proper monitoring and care. Having fibroids does not automatically mean infertility or difficulty becoming a parent.
The good news is that there are multiple treatment options available today, many of which are minimally invasive and highly effective. With the right medical guidance, symptoms can often be managed, and fertility outcomes can improve significantly in cases where fibroids are a contributing factor.
If you are struggling with infertility or have recently been diagnosed with fibroids, the most important step is not to panic or ignore it. Instead, focus on getting a proper evaluation. With the right diagnosis and personalized care, many women are able to move forward with confidence and achieve their pregnancy goals.
