Ovarian Cyst: Symptoms, Causes, Types, Diagnosis & Treatment
An ovarian cyst is a fluid-filled sac that develops in or on an ovary. Ovarian cysts are common, and many cause no symptoms or go away on their own without treatment. However, some cysts can become large, cause pain, rupture, twist the ovary or require further evaluation.
If you have been diagnosed with an ovarian cyst, it is natural to have questions such as:
- What causes an ovarian cyst?
- What are the symptoms of an ovarian cyst?
- Is an ovarian cyst dangerous?
- Can an ovarian cyst affect fertility?
- What size ovarian cyst needs treatment?
- Does every ovarian cyst require surgery?
This guide explains ovarian cyst symptoms, causes, types, diagnosis, treatment and possible effects on fertility in simple language.
What Is an Ovarian Cyst?
An ovarian cyst is a sac that develops within an ovary or on its surface. The ovaries are part of the female reproductive system and contain the eggs that are released during the reproductive years.
Many ovarian cysts develop naturally as part of the menstrual cycle. These are called functional ovarian cysts and are usually harmless. They often disappear within a few menstrual cycles without treatment.
Not every ovarian cyst is the same. The type, size, appearance and symptoms help doctors decide whether monitoring, further testing or treatment is needed.
Ovarian Cyst Symptoms
Many ovarian cysts cause no symptoms and are discovered during an ultrasound or pelvic examination performed for another reason.
When symptoms occur, they may include:
Common Symptoms of Ovarian Cysts
- Pelvic or lower abdominal pain
- A feeling of pressure, fullness or heaviness in the abdomen
- Bloating or abdominal swelling
- Pain during sexual intercourse
- Frequent urination or difficulty emptying the bladder
- Difficulty emptying the bowel
- Heavy, irregular or unusual menstrual bleeding
- Feeling full quickly
The symptoms can vary depending on the size and type of cyst and whether a complication such as rupture or ovarian torsion occurs.
When Should You Seek Urgent Medical Care?
Sudden or severe pelvic or abdominal pain, especially when accompanied by nausea, vomiting, fever, weakness or dizziness, requires urgent medical assessment.
These symptoms can occur with complications such as ovarian torsion or a ruptured cyst.
What Causes Ovarian Cysts?
The causes of ovarian cysts vary by type.
1. Functional Ovarian Cysts
Functional cysts develop as part of the normal menstrual cycle.
They include:
- Follicular cysts: Develop when a follicle does not release an egg and continues to grow.
- Corpus luteum cysts: Develop after ovulation, when the follicle transforms into the corpus luteum and fluid accumulates within it.
Functional cysts are the most common type and usually resolve without treatment.
2. Endometriosis
Endometriosis can cause tissue similar to the uterine lining to grow outside the uterus. When this tissue affects an ovary, it can form an ovarian cyst called an endometrioma.
Endometriomas may be associated with pelvic pain and difficulties with fertility.
3. Pregnancy
Some ovarian cysts can remain during early pregnancy. For example, a corpus luteum cyst may be seen during pregnancy and may resolve naturally.
4. Fertility Medicines
Some medicines used to stimulate ovulation can increase the chance of developing ovarian cysts or enlarged ovaries. Your fertility specialist can monitor ovarian response during treatment.
5. Pelvic Infections and Other Conditions
Certain pelvic infections and underlying reproductive health conditions may also be associated with ovarian cysts.
What Are the Types of Ovarian Cysts?
Ovarian cysts can be broadly divided into functional and other types.
Functional Cysts
Functional cysts are related to the menstrual cycle and include:
- Follicular cysts
- Corpus luteum cysts
They are generally benign and often disappear on their own.
Dermoid Cysts
Dermoid cysts, also called mature cystic teratomas, develop from cells that can form different types of body tissue. They may contain tissues such as hair, skin or teeth.
Cystadenomas
Cystadenomas develop from cells on the surface of the ovary. They may contain watery or mucous-like material and can sometimes become large.
Endometriomas
Endometriomas are ovarian cysts associated with endometriosis. They may affect pelvic health and, in some cases, fertility.
Ovarian Cyst vs PCOS: Are They the Same?
No. An ovarian cyst and PCOS are not the same condition.
Polycystic ovary syndrome (PCOS) is a hormonal and metabolic condition that can affect ovulation and menstrual cycles. Despite its name, PCOS should not be understood simply as having one or more ovarian cysts.
A person can have an ovarian cyst without having PCOS, and a person with PCOS does not necessarily have ovarian cysts in the usual clinical sense.
If you have irregular periods, excess androgen-related symptoms or difficulty conceiving, a fertility specialist can determine whether PCOS or another condition may be involved.
Can Ovarian Cysts Affect Fertility?
In most cases, an ovarian cyst does not prevent pregnancy.
However, fertility effects can depend on the type of cyst and the underlying condition. For example, endometriomas may be associated with difficulty becoming pregnant. PCOS can also affect fertility because irregular ovulation may make conception more difficult.
Some cysts do not generally affect fertility. Functional cysts, cystadenomas and dermoid cysts are not usually associated with infertility.
Ovarian Cyst and IVF Treatment
If you are undergoing fertility treatment, your doctor will assess the cyst’s size, appearance, type and effect on the ovaries before deciding how to proceed.
Treatment is individualised. Removing a cyst is not automatically necessary before IVF.
If surgery is being considered, fertility preservation should be discussed because the effect of surgery can depend on the type of cyst and ovarian involvement.
How Are Ovarian Cysts Diagnosed?
An ovarian cyst may be discovered during a pelvic examination or an imaging test.
1. Pelvic Examination
A doctor may perform a pelvic examination to look for tenderness, swelling or other abnormalities.
2. Ultrasound
Pelvic ultrasound, particularly transvaginal ultrasound when appropriate, is commonly used to evaluate ovarian cysts.
Ultrasound can help assess:
- Cyst size
- Location
- Shape
- Whether it is fluid-filled or contains solid components
- Internal features of the cyst
These findings help the doctor determine whether monitoring or further evaluation is appropriate.
3. Pregnancy Test
A pregnancy test may be recommended because pregnancy-related ovarian changes can affect the interpretation of an ovarian mass or cyst.
4. Blood Tests
Blood tests may sometimes be recommended depending on the cyst’s appearance, the patient’s age and other clinical factors.
In selected situations, doctors may use tumour-marker testing. However, an elevated tumour marker does not automatically mean ovarian cancer, because some benign conditions can also affect these results.
5. Additional Imaging or Laparoscopy
Depending on the clinical situation, additional imaging or laparoscopy may be considered.
The appropriate test depends on the cyst’s characteristics and the level of concern.
Ovarian Cyst Treatment
Not every ovarian cyst requires treatment.
Treatment depends on factors such as:
- Cyst size
- Cyst appearance
- Type of cyst
- Symptoms
- Age
- Menopausal status
- Whether the cyst is changing over time
- Fertility plans
- Concern about complications or malignancy
1. Watchful Waiting
Many small, simple ovarian cysts do not need immediate treatment.
Your doctor may recommend observation and a repeat ultrasound after a suitable interval to determine whether the cyst has disappeared or changed.
2. Medicines
Medicines may be prescribed to manage symptoms or treat an underlying condition.
Hormonal contraceptives can reduce the development of some new functional cysts by preventing ovulation, but they generally do not shrink an existing ovarian cyst.
3. Laparoscopic Ovarian Cystectomy
A laparoscopic cystectomy is a minimally invasive procedure used to remove an ovarian cyst while attempting to preserve the ovary when clinically appropriate.
Whether cyst removal is appropriate depends on the cyst’s type, size, and characteristics, as well as the patient’s fertility goals.
4. Laparotomy
A laparotomy is an open surgical procedure involving a larger abdominal incision. It may be considered for very large cysts or when concerns warrant a different surgical approach.
5. Oophorectomy
In selected cases, removal of the affected ovary may be necessary. The decision depends on the cyst’s characteristics, the patient’s age, fertility plans and the possibility of cancer or other complications.
Whenever possible, fertility-preserving options should be discussed with the treating specialist.
What Size of Ovarian Cyst Is Dangerous?
There is no single cyst size that automatically means an ovarian cyst is dangerous.
Size is only one part of the assessment. Doctors also consider:
- Whether the cyst is simple or complex
- Its ultrasound appearance
- Whether it is growing
- Whether it causes symptoms
- The patient’s age
- Menopausal status
- Whether there are complications
- Whether there are features that raise concern for malignancy
Therefore, the old rule that “an ovarian cyst larger than 5 cm is dangerous” is too simplistic.
A large cyst may be benign, while a smaller cyst may still require evaluation depending on its appearance and symptoms.
Can an Ovarian Cyst Go Away on Its Own?
Yes. Many functional ovarian cysts resolve on their own within a few months or several menstrual cycles.
Your doctor may recommend follow-up ultrasound to confirm that the cyst is shrinking or has disappeared.
However, persistent, enlarging, symptomatic or complex cysts may require additional evaluation.
Ovarian Cyst Complications
Most ovarian cysts do not cause serious complications. However, complications can occur.
Ovarian Torsion
A large cyst can sometimes cause the ovary to twist, potentially reducing its blood supply.
Sudden severe pelvic pain accompanied by nausea or vomiting requires urgent medical attention.
Cyst Rupture
An ovarian cyst can sometimes rupture and cause sudden pelvic or abdominal pain. In some cases, bleeding can occur.
Infertility or Reduced Fertility
Some ovarian conditions, particularly endometriomas and conditions that affect ovulation, may be associated with difficulty conceiving.
Malignancy
Most ovarian cysts are benign. However, some ovarian masses can be cancerous, and the likelihood of malignancy varies with factors such as age, menopausal status and the characteristics of the cyst.
Can Ovarian Cysts Be Prevented?
There is no guaranteed way to prevent most ovarian cysts because many develop naturally as part of the menstrual cycle.
However, paying attention to changes in your menstrual cycle and seeking medical evaluation for persistent or unusual symptoms can help identify ovarian problems early.
Regular gynaecological care can also be useful, particularly if you have a history of ovarian cysts or an underlying condition such as endometriosis.
When Should You See a Doctor for an Ovarian Cyst?
Consider consulting a gynaecologist or fertility specialist if you have:
- Persistent pelvic pain
- Repeated bloating or abdominal pressure
- Significant changes in your periods
- Pain during intercourse
- Difficulty becoming pregnant
- A cyst that has been detected on ultrasound
- A cyst that is increasing in size
- A history of recurrent ovarian cysts
Seek Urgent Medical Care If You Have
- Sudden severe pelvic or abdominal pain
- Severe pain with nausea or vomiting
- Fever with significant abdominal or pelvic pain
- Severe weakness, dizziness or fainting
These symptoms can indicate a complication and should not be ignored.
Frequently Asked Questions About Ovarian Cysts
Is an ovarian cyst dangerous?
Most ovarian cysts are not dangerous and resolve without treatment. However, some cysts can rupture, cause ovarian torsion, persist, grow or have features requiring further evaluation.
Can an ovarian cyst cause infertility?
Most ovarian cysts do not cause infertility. However, certain conditions associated with ovarian cysts, such as endometriosis and PCOS-related ovulatory problems, can affect fertility.
What is the most common ovarian cyst?
Functional ovarian cysts are the most common type. They develop as part of the menstrual cycle and usually resolve on their own.
Do ovarian cysts need surgery?
Not always. Many cysts can be monitored without surgery. Surgery may be considered when a cyst is large, persistent, symptomatic, growing or has features that require further evaluation.
Can I get pregnant with an ovarian cyst?
Yes, many women with ovarian cysts can become pregnant. The effect on fertility depends mainly on the type of cyst and the underlying condition.
Can an ovarian cyst disappear naturally?
Yes. Many functional ovarian cysts resolve on their own within a few months. Follow-up may be recommended depending on the cyst’s appearance and your symptoms.
Does every ovarian cyst mean cancer?
No. Most ovarian cysts are benign. However, some cysts or ovarian masses require further evaluation, particularly depending on age, menopausal status and ultrasound characteristics.
