Impact of Uterine Fibroids on Fertility: What You Need to Know

Uterine fibroids

I would like to ask, during a previous health check-up, uterine fibroids were detected.
Will this affect fertility? Is it difficult to conceive?

Xiao Hua, 30~39 year old female. Ask Date: 2009/09/20

Dr. Dong Yuhong reply Obstetrics and Gynecology

Uterine fibroids can affect fertility, and their impact is related to factors such as size and location.
If a small fibroid measuring 2-3 cm is found during a health check and is not located within the uterine cavity (i.e., it is not a submucosal fibroid), the likelihood of it affecting fertility is low.
If you are of marriageable age and wish to have your own children after getting married, it is advisable to plan your family’s reproductive schedule as early as possible.
If you have any questions, you are welcome to visit the Department of Obstetrics and Gynecology at Taipei City Hospital, and we would be happy to assist you.

More Info

Uterine fibroids, also known as leiomyomas, are non-cancerous growths that develop in the uterus. They are quite common, with many women experiencing them at some point in their lives. The impact of uterine fibroids on fertility can vary significantly depending on several factors, including the size, location, and number of fibroids present.

1. Types of Fibroids and Their Locations: Fibroids can be classified based on their location within the uterus:
- Submucosal fibroids: These grow just beneath the lining of the uterus and can distort the uterine cavity. They are often associated with infertility and can lead to complications during pregnancy.

- Intramural fibroids: These develop within the muscular wall of the uterus. Depending on their size and location, they may or may not affect fertility.

- Subserosal fibroids: These grow on the outer wall of the uterus and typically do not affect fertility directly, although they can cause other complications.

2. Impact on Fertility: The presence of fibroids can affect fertility in several ways:
- Distortion of the Uterine Cavity: Submucosal fibroids can change the shape of the uterine cavity, making it more difficult for an embryo to implant successfully. This can lead to issues with conception and may increase the risk of miscarriage.

- Hormonal Imbalances: Fibroids can produce hormones that may interfere with the normal hormonal balance necessary for ovulation and implantation.

- Blockage of Fallopian Tubes: In some cases, fibroids can grow large enough to block the fallopian tubes, preventing sperm from reaching the egg or hindering the passage of a fertilized egg to the uterus.

3. Symptoms and Diagnosis: Many women with fibroids experience no symptoms, while others may have heavy menstrual bleeding, pelvic pain, or pressure symptoms. If you have been diagnosed with fibroids, it is essential to discuss your specific situation with your healthcare provider. They may recommend imaging studies, such as an ultrasound or MRI, to assess the size and location of the fibroids.

4. Treatment Options: If fibroids are determined to be affecting your fertility, several treatment options are available:
- Medications: Hormonal treatments can help manage symptoms but may not eliminate fibroids.

- Surgical Options: Procedures such as myomectomy (removal of fibroids) can improve fertility outcomes. In some cases, a hysterectomy (removal of the uterus) may be necessary, but this is typically only recommended for women who do not wish to become pregnant in the future.

- Monitoring: If the fibroids are small and not causing symptoms, your doctor may recommend monitoring them without immediate intervention.

5. Pregnancy Considerations: If you become pregnant with fibroids, it is important to have regular prenatal care. While many women with fibroids have healthy pregnancies, there is a potential for complications such as preterm labor, placental abruption, or the need for a cesarean section.

In conclusion, while uterine fibroids can impact fertility, the extent of their effect varies widely among individuals. If you are planning to conceive and have been diagnosed with fibroids, it is crucial to have a thorough discussion with your healthcare provider. They can help you understand the specific implications for your fertility and recommend appropriate management strategies to optimize your chances of a successful pregnancy.
