Fibroid tumors, also called uterine fibroids or leiomyomas, are growths made of muscle and fibrous tissue. They form in or around the uterus. These growths are non-cancerous and are very common. Many women have fibroids at some point during their reproductive years, often without knowing it.
Some fibroids are small and don’t cause any problems. Others can grow larger and lead to symptoms such as heavy periods, pelvic pain, or fertility issues. The size, number, and location of the fibroids matter. These factors determine how fibroids affect a woman’s chances of getting pregnant.
Where Do Fibroids Grow?
Fibroids can grow in different parts of the uterus. Their location plays a big role in whether they will affect fertility. There are three main types of fibroids:
Intramural fibroids grow within the muscular wall of the uterus. They are the most common type. If they get too big, they may distort the shape of the uterus, which could make it harder for a fertilized egg to implant.
Submucosal fibroids develop just underneath the lining of the uterus and can grow into the uterine cavity. Even small submucosal fibroids can interfere with the implantation of an embryo or cause miscarriage.
Subserosal fibroids grow on the outer surface of the uterus. These typically don’t affect fertility unless they become very large and put pressure on other organs.
Can Fibroids Prevent Pregnancy?
Not all fibroids cause fertility problems. Many women with fibroids conceive naturally and carry pregnancies to term. But in some cases, fibroids can make it more difficult to get pregnant.
Fibroids can block the fallopian tubes, preventing sperm from reaching the egg. They can also change the shape of the uterus, making it harder for an embryo to implant. If the blood flow to the uterus is disrupted by fibroids, the uterine lining may not be able to support a pregnancy.
Submucosal fibroids are most likely to cause problems. These can increase the risk of early pregnancy loss and may reduce the chances of successful embryo implantation, even during fertility treatments like IVF.
Intramural fibroids, especially if they are large, may also reduce fertility by affecting the uterus’s ability to contract and maintain a pregnancy. Subserosal fibroids usually have less effect on fertility, but again, size and number are key factors.
Can You Get Pregnant If You Have Fibroids?
Yes, you can still get pregnant with fibroids. Many women do, often without any complications. The chance of getting pregnant depends on:
- The size and number of fibroids
- The location of the fibroids
- Whether you have any other fertility problems
Some women with fibroids get pregnant easily and have normal pregnancies. Others may need treatment first. If you have fibroids and have been trying to conceive for over a year without success, it’s a good idea to see a fertility specialist.
What Happens If You Get Pregnant with Fibroids?
Pregnancy with fibroids is usually possible, but there are some risks. Fibroids may grow during pregnancy due to increased levels of estrogen and other hormones. This growth can cause pain, especially in the second and third trimesters.
Other possible pregnancy complications include:
Miscarriage: Women with fibroids are slightly more likely to have a miscarriage, especially in the first trimester.
Preterm labor: Some fibroids can trigger uterine contractions early, leading to premature birth.
Bleeding: If a fibroid grows close to the placenta or uterine lining, it may cause bleeding during pregnancy.
Restricted fetal growth: Large fibroids can limit space in the womb, restricting the baby’s growth.
Placental abruption: In rare cases, fibroids can cause the placenta to separate from the uterine wall before delivery, which is a serious condition.
Cesarean delivery (C-section): Fibroids may block the birth canal or interfere with uterine contractions, making natural delivery harder.
Despite these risks, many women with fibroids go on to have healthy pregnancies. Close monitoring and regular prenatal care are essential.
How Are Fibroids Diagnosed?
Fibroids are often found during routine pelvic exams or prenatal ultrasounds. If fibroids are suspected, your doctor might recommend more imaging tests, such as:
- Ultrasound: The most common method. It shows the size, shape, and number of fibroids.
- MRI: Provides more detailed images and is useful for planning surgery.
- Hysterosonography: A saline solution is placed in the uterus to get clearer ultrasound images.
- Hysterosalpingography (HSG): An X-ray test that checks the uterus and fallopian tubes, often used during fertility evaluations.
- Hysteroscopy: A thin tube with a camera is inserted into the uterus to look for fibroids or other abnormalities.
Can Fibroids Be Treated Before Pregnancy?
Yes. If fibroids are causing fertility problems, your doctor might suggest treating them before you try to conceive. Not all fibroids need treatment. The best approach depends on your symptoms and fertility goals.
Some common treatments include:
Myomectomy: This is surgery to remove fibroids while preserving the uterus. It’s a good option for women who want to get pregnant. Recovery may take a few weeks, and doctors often recommend waiting two to three months before trying to conceive.
Hysteroscopic resection: This minimally invasive procedure removes submucosal fibroids through the cervix using a small camera and tools. It’s often used for fibroids that grow into the uterine cavity.
Medication: Some hormonal medications can shrink fibroids temporarily. These drugs are not used during pregnancy and are usually given before surgery. They’re not a long-term solution for women who want to conceive soon.
Uterine artery embolization (UAE): This blocks blood flow to the fibroids, causing them to shrink. However, it’s generally not recommended for women who want to become pregnant, as it may affect the uterus’s ability to support a baby.
What If You Are Already Pregnant with Fibroids?
If you’re already pregnant and have fibroids, your healthcare provider will monitor your pregnancy closely. Most fibroids do not grow during pregnancy, but some may increase in size due to hormone changes.
Doctors typically use regular ultrasounds to track fibroid growth and check the baby’s development. Pain management may be needed if fibroids cause discomfort. Avoiding heavy lifting and staying well-hydrated can also help.
Doctors usually avoid treating fibroids during pregnancy unless there is a serious complication. Surgical removal during pregnancy is rare and risky. Most treatments are postponed until after delivery.
Can You Have a Natural Delivery with Fibroids?
Yes, many women with fibroids can have a vaginal birth. However, if fibroids are blocking the birth canal or are located near the cervix, a cesarean delivery may be necessary.
Your doctor will assess the situation as your pregnancy progresses and will discuss your delivery options with you. The presence of fibroids alone doesn’t mean you must have a C-section.
Can Fibroids Come Back After Treatment?
Yes, fibroids can grow back after treatment, especially in younger women who are still producing hormones. Myomectomy removes existing fibroids but does not prevent new ones from forming.
That said, treatment can improve fertility and reduce symptoms, allowing many women to conceive successfully. Regular follow-up with your doctor is important to monitor your reproductive health.
What Should You Do If You Have Fibroids and Want to Get Pregnant?
Start by talking to your doctor. They may refer you to a fertility specialist or perform tests to understand how your fibroids may be affecting you. Depending on the size and location of the fibroids, they may suggest waiting and trying naturally or moving forward with treatment first.
If you’re already pregnant and have fibroids, don’t panic. Most pregnancies go well. Stay in close contact with your healthcare provider and attend all prenatal appointments. Let them know right away if you experience pain, bleeding, or any unusual symptoms.
The Emotional Side of Fibroids and Fertility
Dealing with fibroids while trying to get pregnant can be emotionally challenging. The physical symptoms are difficult enough, but the uncertainty about fertility can create stress and anxiety.
It’s important to seek support. Talk to your doctor openly about your concerns. Consider joining support groups or talking to a counselor who specializes in reproductive health. You are not alone, and many women have walked the same path.
With proper care, planning, and treatment when needed, many women with fibroids can conceive and have healthy babies.
Conclusion
Fibroid tumors, although common, present a range of challenges for women who are trying to conceive. While many women with fibroids are able to get pregnant naturally, others may experience difficulties depending on the size, number, and location of the fibroids. Submucosal fibroids, in particular, are most likely to cause problems with implantation and increase the risk of miscarriage.
However, having fibroids doesn’t mean that pregnancy is out of reach. Many women with fibroids go on to have healthy pregnancies and deliver healthy babies. Understanding the type of fibroids, monitoring them closely during pregnancy, and exploring treatment options such as myomectomy can significantly improve fertility outcomes for women trying to conceive.
If you’re planning to get pregnant and have fibroids, it’s crucial to consult with your healthcare provider. With the right approach, treatment, and care, you can still achieve your goal of having a family, even with fibroid tumors.
