Can You Get Pregnant with Uterine Fibroids? Understanding Their Impact on Pregnancy
Yes, you can get pregnant with uterine fibroids, and many women with fibroids go on to have healthy pregnancies. Fibroids do not automatically cause infertility. Their effect on conception and pregnancy depends largely on their size, number, and location, particularly whether they alter the shape of the uterine cavity.
Not every fibroid affects fertility in the same way. Submucosal fibroids and fibroids that distort the uterine cavity are more likely to interfere with implantation and conception. Others may have little or no effect on fertility. This makes an individual assessment important when planning a pregnancy.
At Archish Fertility and IVF Clinic in Bangalore, our fertility specialists evaluate the fibroids alongside your overall reproductive health. This helps determine whether they need monitoring, treatment, or no intervention before you try to conceive.
What are Uterine Fibroids?
Uterine fibroids, also called leiomyomas or myomas, are benign, non-cancerous growths that develop in or around the uterus. They are made of muscle and fibrous tissue and can range from the size of a seed to a mass large enough to change the shape of the uterus.
Fibroids are hormone-sensitive, which means estrogen and progesterone influence how they grow. They are one of the most common gynecological conditions in women of reproductive age, with prevalence estimates ranging from 20% to 40% in India. Most fibroids cause no symptoms at all. When they do, common signs include heavy periods, pelvic pressure, and, in some cases, fertility challenges.
What are the Types of Uterine Fibriods?
Fertility specialists classify fibroids by where they grow in relation to the uterine cavity. Location, more than size alone, decides whether a fibroid is likely to cause problems. The following table helps in understanding the different types of fibroids, their location and impact on the uterus:
| Type of fibroid | Where it develops | Possible effect on fertility |
|---|---|---|
| Submucosal | Bulges into the uterine cavity | More likely to affect implantation and fertility |
| Intramural | Develops within the uterine muscle wall | May affect fertility if it is large or distorts the cavity |
| Subserosal | Grows on the outer surface of the uterus | Usually has little effect on conception if it does not distort the cavity |
Do Uterine Fibroids Affect Fertility?
Yes, some fibroids can affect fertility, but many do not. The effect is more significant when a fibroid changes the uterine cavity where an embryo needs to implant and grow.
Fibroids may affect fertility by:
- Distorting the Uterine Cavity: Submucosal fibroids can protrude into the cavity and interfere with implantation.
- Changing the Uterine Environment: Some larger fibroids may affect the structure or blood flow around the uterine lining.
- Affecting the Fallopian Tubes: A fibroid located near a tubal opening may interfere with the passage of sperm or egg.
- Affecting Implantation: Fibroids that distort the cavity may make implantation more difficult.
However, simply having a fibroid does not mean you will have difficulty conceiving. Current evidence does not show that all fibroids reduce the chance of pregnancy. The concern is greater with submucosal fibroids and intramural fibroids that distort the uterine cavity.
What Happens If You Become Pregnant with Fibroids?
Most women with fibroids can have a healthy pregnancy. However, fibroids may change in size during pregnancy, so your doctor may monitor them through ultrasound.
Some fibroids can also undergo red degeneration, which may cause sudden abdominal pain. This is usually managed conservatively with medical supervision.
The presence of a fibroid does not automatically mean that your pregnancy will be complicated.
A Clinical Study on Can Fibroids Affect Pregnancy?
Yes, fibroids are associated with a higher risk of certain pregnancy and delivery complications.
A 2024 meta-analysis covering 24 studies and 237,509 pregnancies found associations between fibroids and complications including preterm birth, cesarean delivery, placenta previa, placental abruption, postpartum hemorrhage, breech presentation, and preeclampsia. The researchers also found that larger fibroids were associated with higher risks of some complications.

These findings do not mean that complications are inevitable. Your risk depends on the fibroid and other factors affecting your pregnancy.
Can You Have a Normal Delivery with Fibroids?
Yes. Fibroids do not automatically mean that you need a C-section.
Your delivery plan may depend on the size and location of the fibroid, the baby’s position, the placenta’s location, and whether the fibroid obstructs the birth canal.
Your obstetrician can assess these factors as your pregnancy progresses.
When Should You See a Doctor for Fibroids and Pregnancy?
If you know you have fibroids and are planning a pregnancy, an early consultation can help determine whether they need treatment or simply monitoring.
You should also seek medical advice if you have:
- Difficulty conceiving
- Heavy or painful periods
- Repeated pregnancy loss
- A fibroid that distorts the uterine cavity
- Severe pelvic pain during pregnancy
- Vaginal bleeding during pregnancy
A transvaginal ultrasound is commonly used to assess the uterus and fibroids. Depending on your symptoms and fertility history, your doctor may recommend additional tests to examine the uterine cavity.
Should Fibroids Be Removed Before Getting Pregnant?
Not necessarily.
Treatment is considered based on the fibroid’s location, size, symptoms, and effect on the uterine cavity. A submucosal fibroid that distorts the cavity may require treatment, while a small fibroid that does not affect the cavity may only need monitoring.
For suitable cavity-distorting fibroids, myomectomy may be considered to improve the chances of pregnancy. However, removing every fibroid before pregnancy is not recommended.
How Can IVF and Assisted Fertility Options Help for Fibroids?
IVF can help by fertilizing the egg and sperm in a laboratory and transferring the resulting embryo directly into the uterus. This can be useful when fibroids are accompanied by other fertility factors or when pregnancy has not occurred through other approaches. However, fibroids that significantly distort the uterine cavity may need to be treated before embryo transfer to support implantation.
At Archish Fertility and IVF Clinic in Bangalore, our fertility specialists assess your fibroids along with factors such as age, ovarian reserve, fallopian tube health, sperm health, and previous fertility history. This helps determine whether IVF is appropriate and whether any treatment is needed before proceeding.

FAQs
Submucosal fibroids are linked to a higher miscarriage risk in some studies, though cause-and-effect is not fully established. Risk appears highest with multiple submucosal fibroids in women already facing fertility challenges.
Yes. Myomectomy removes existing fibroids, but new fibroids can develop later. Regular follow-up may be recommended based on your individual situation.
Treatment depends on the symptoms, size, location, and pregnancy plans. Some fibroids may only require monitoring, while others may need medication or a procedure.
Yes. Many fibroids shrink once hormone levels drop after delivery, especially during breastfeeding, though not all reduce in size.
In many cases, yes. It depends on the fibroid's size and location, particularly if it blocks the birth canal or affects the baby's position.
Large or strategically located fibroids may be associated with certain pregnancy complications, including fetal growth problems. Your doctor may monitor the baby's growth during pregnancy when necessary.
