This video explains what uterine fibroids are, outlines the four main types, and discusses common uterine fibroids symptoms such as heavy menstrual bleeding and irregular cycles. It explores how fibroids can impact fertility through implantation disruption, blocked fallopian tubes, hormonal imbalance, and miscarriage risk. The presentation also highlights diagnosis methods, medical treatment options, and holistic approaches to managing fibroids before and during pregnancy.
Uterine fibroids are one of the most common reproductive conditions affecting women of reproductive age. Many women will develop fibroids at some point in their lives, yet a large number never even realize they have them. For others, symptoms can significantly affect daily life and raise concerns about fertility and pregnancy.
If you are trying to conceive or planning a pregnancy, understanding what uterine fibroids are and recognizing uterine fibroids symptoms early can help you make informed decisions about your reproductive health.
Quick answer: Uterine fibroids are non-cancerous growths that develop in the muscular wall of the uterus. While many women experience no symptoms, others may have heavy bleeding, pelvic pain, or fertility challenges depending on the size and location of the fibroids.
What Are Uterine Fibroids?
Uterine fibroids, also known as leiomyomas, are benign growths that form within the muscle tissue of the uterus. They are not cancerous and in most cases do not increase the risk of uterine cancer.
Although the exact cause of uterine fibroids is not fully understood, they are strongly linked to hormonal imbalances, particularly estrogen dominance. Genetic and environmental factors may also contribute.
Fibroids can vary greatly in size. Some remain very small and undetectable without imaging, while others can grow large enough to distort the shape of the uterus.
Importantly, many women with fibroids conceive naturally and carry healthy pregnancies. However, for some, fibroids can interfere with fertility depending on their type and location.
Types of Uterine Fibroids
There are four primary types of uterine fibroids. Their location plays a key role in determining whether they cause symptoms or affect fertility.
Intramural Fibroids
Intramural fibroids grow within the muscular wall of the uterus. They are the most common type. In many cases, they do not significantly protrude into the uterine cavity, meaning they may not directly interfere with implantation.
However, larger intramural fibroids can alter uterine structure and potentially affect fertility.
Subserosal Fibroids
Subserosal fibroids develop on the outer surface of the uterus. These typically grow outward rather than into the uterine cavity. Because of their position, they are less likely to interfere directly with implantation but can cause pelvic pressure or discomfort.
Submucosal Fibroids
Submucosal fibroids grow into the inner cavity of the uterus. These are often the most impactful when it comes to fertility. Because they protrude into the uterine lining, they can distort the shape of the cavity, interfere with implantation, and increase miscarriage risk.

Pedunculated Fibroids
Pedunculated fibroids grow on a stalk either inside or outside the uterus. Their impact depends on where they are positioned. Some may cause no issues at all, while others can create complications depending on size and placement.
Uterine Fibroids Symptoms to Watch For
One of the challenges with fibroids is that many women experience no symptoms. However, when symptoms are present, they can significantly affect quality of life.
The most common uterine fibroids symptoms include:
- Very heavy menstrual bleeding
- Prolonged periods
- Large blood clots
- Pelvic pain or pressure
- Pain during intercourse
- Irregular bleeding outside normal cycle days
Heavy bleeding is often the most noticeable symptom. Women may find themselves changing pads or tampons frequently, staining clothing or bedding, or experiencing waves of bleeding that subside and return within the same cycle.
If you are experiencing heavy menstrual bleeding, it is important to seek evaluation. A pelvic ultrasound, either abdominal or transvaginal, can typically confirm whether fibroids are present and identify their size and location.
Early diagnosis is especially important if you are planning to conceive.
How Uterine Fibroids Affect Fertility
Understanding how uterine fibroids affect fertility requires examining several mechanisms.
Distortion of Uterine Shape
Large fibroids can alter the structure of the uterus. When the uterine cavity is distorted, implantation may become more difficult. A fertilized egg needs a healthy, receptive lining to attach successfully.
Blocked Fallopian Tubes
In certain cases, fibroids located near the fallopian tubes may block sperm from reaching the egg or prevent the fertilized egg from traveling properly.
Reduced Blood Flow
Fibroids require their own blood supply. Larger growths may draw blood flow away from the uterine lining, potentially reducing implantation potential.
Hormonal Imbalances
Many women with fibroids also experience estrogen dominance and progesterone insufficiency. Balanced estrogen and progesterone are essential for maintaining a healthy uterine lining and supporting early pregnancy.
Hormonal imbalance can compound fertility challenges, especially if fibroids are already affecting uterine structure.

Fibroids and Pregnancy Complications
Even if conception occurs, fibroids may increase the risk of complications during pregnancy.
These can include:
- Increased risk of miscarriage
- Abnormal placental positioning
- Pain as the uterus expands
- Increased likelihood of cesarean delivery
Some women with fibroids may not be candidates for vaginal delivery depending on the size and placement of the fibroids.
However, it is important to emphasize that many women with fibroids have completely healthy pregnancies and deliveries.
Diagnosis and Early Detection
If you suspect fibroids based on uterine fibroids symptoms such as heavy bleeding or irregular cycles, early evaluation is recommended.
Diagnosis typically involves:
- Pelvic examination
- Ultrasound imaging
- Transvaginal ultrasound
- Occasionally MRI imaging
Early detection allows you to assess:
- Number of fibroids
- Size
- Location
- Potential impact on fertility
If you are planning pregnancy, understanding this information ahead of time helps you make informed decisions.
Treatment Options for Uterine Fibroids
Treatment depends on symptoms, fertility goals, and fibroid size and location.
Medical Treatments
Gynecologists may recommend:
- Hormonal therapies
- Intrauterine devices
- Surgical removal
- Myomectomy
- Uterine artery embolization
Medical and surgical routes should always be discussed thoroughly with a specialist.
Holistic and Nutritional Support
Some women choose to explore lifestyle and nutritional approaches to manage symptoms and support hormonal balance.
Hormonal regulation through diet can play a role in reducing estrogen dominance. You can explore more detailed dietary strategies in nutrition for treating uterine fibroids, which outlines nutritional considerations for hormone balance.
Supplement strategies are also commonly explored. Certain supplements may support hormonal balance and inflammation reduction. A deeper look at this approach can be found in supplements for managing uterine fibroids, which explains evidence-based supplementation guidance.
Additionally, emerging research highlights the importance of reproductive tract health. The uterine microbiome may influence implantation and fertility outcomes. You can learn more about this connection in uterine microbiome and fertility, which explores how microbial balance may support reproductive health.
Natural Remedies Versus Medical Intervention
There is no universal answer to whether medical or holistic treatment is best. Each woman’s situation is different.
Factors to consider include:
- Severity of symptoms
- Fertility timeline
- Size and type of fibroids
- Overall hormonal balance
- Personal preferences
Some women experience symptom improvement with dietary changes and targeted supplementation. Others may require surgical intervention to protect fertility.
The key is informed decision-making.
Can You Get Pregnant With Uterine Fibroids?
Yes, many women with fibroids conceive naturally.
However, it is important to:
- Identify fibroid type
- Understand location
- Assess hormonal balance
- Monitor bleeding patterns
- Seek early diagnosis
With appropriate support, fertility outcomes can improve significantly.
Final Thoughts
What are uterine fibroids? They are common, non-cancerous growths that may or may not impact your fertility depending on their size and location.
Recognizing uterine fibroids symptoms such as heavy bleeding and irregular cycles is essential for early intervention. While fibroids can affect implantation, blood flow, and pregnancy outcomes, many women successfully conceive and carry healthy pregnancies.
Understanding your body is empowering. Early diagnosis, informed treatment decisions, and balanced hormonal support can significantly improve both fertility outcomes and overall reproductive health.
