A hemorrhagic ovarian cyst is an ovarian cyst in which bleeding occurs inside the cyst. It most commonly develops when a functional ovarian cyst, particularly a corpus luteum cyst, bleeds.
Hemorrhagic ovarian cysts are relatively common in women who are ovulating. Many are benign and resolve on their own without surgery.
However, not every ovarian cyst that contains blood is the same. The appearance of a cyst on ultrasound, its size, symptoms, and how it changes over time help your gynaecologist determine what it is and whether treatment or follow-up is needed.
If you have been told that you have a hemorrhagic ovarian cyst, it is understandable to wonder whether it is dangerous, whether it will affect fertility, or whether you need surgery. In most cases, the answer depends on the individual situation.
A hemorrhagic ovarian cyst is an ovarian cyst that has bled internally.
Ovarian cysts are fluid-filled or partly fluid-filled structures that develop in or on an ovary. During a normal menstrual cycle, follicles develop in the ovary as part of ovulation. Sometimes a functional cyst forms and a blood vessel within it can bleed.
The blood remains inside the cyst, producing what is known as a hemorrhagic cyst.
A hemorrhagic ovarian cyst is therefore not necessarily a completely separate type of cyst. It often describes a functional ovarian cyst complicated by bleeding.
A common sequence is:
Follicle develops → ovulation occurs → functional cyst forms → bleeding occurs inside the cyst → hemorrhagic cyst develops
One common example is bleeding into a corpus luteum cyst after ovulation.
The corpus luteum normally develops after the egg is released and produces hormones that support the menstrual cycle and early pregnancy.
If bleeding occurs inside this structure, it can form a hemorrhagic cyst.
In many women, there is no specific preventable reason.
Hemorrhagic ovarian cysts can occur as part of the normal menstrual cycle in women who ovulate.
Factors that may be relevant include:
Normal ovulation
Development of functional ovarian cysts
Bleeding from a blood vessel within a cyst
Medicines that affect blood clotting
Conditions that increase the tendency to bleed
However, simply developing a hemorrhagic cyst does not mean that you have done something wrong.
It is also important to remember that an ultrasound appearance suggesting a hemorrhagic cyst may sometimes overlap with other ovarian conditions. Your doctor interprets the ultrasound findings together with your symptoms and clinical history.
They can be a common benign finding in women who are ovulating.
A hemorrhagic cyst is not considered “normal” in the sense that every woman will have one, but functional ovarian cysts and bleeding into them can occur as part of reproductive-age ovarian activity.
Many hemorrhagic cysts resolve naturally over time.
Whether a particular cyst can simply be observed depends on factors such as:
Your age
Whether you are still menstruating
Cyst size
Ultrasound appearance
Symptoms
Whether the cyst is changing in size
Whether there are any concerning findings
Some hemorrhagic ovarian cysts cause no symptoms and are discovered incidentally during an ultrasound.
When symptoms occur, they may include:
Lower abdominal or pelvic pain
Pain on one side
Sudden pelvic pain
Pain around the time of ovulation or menstruation
Abdominal discomfort or pressure
Pain during sexual intercourse in some cases
Bloating or a feeling of fullness
The severity of symptoms can vary considerably.
A small cyst may cause significant pain in one woman while a larger cyst may cause little or no discomfort in another.
The bleeding in a hemorrhagic ovarian cyst is usually inside the cyst itself.
This does not necessarily mean that you will have vaginal bleeding.
Some women may experience changes in their menstrual bleeding or spotting, but vaginal bleeding has many possible causes and cannot by itself confirm a hemorrhagic ovarian cyst.
If you have abnormal vaginal bleeding, your gynaecologist may need to evaluate other possible causes as well.
Yes.
A hemorrhagic cyst can sometimes cause sudden or significant pelvic pain, particularly if there is rapid bleeding into the cyst or if the cyst ruptures.
However, severe or sudden pelvic pain should not automatically be assumed to be due to a known ovarian cyst.
Other urgent conditions, including ovarian torsion, ruptured cyst with significant internal bleeding, ectopic pregnancy, appendicitis or other abdominal conditions, can cause similar symptoms.
Sometimes a hemorrhagic ovarian cyst can rupture.
When this happens, the blood or cyst fluid can enter the pelvic cavity and cause sudden pelvic or abdominal pain.
Many ruptured cysts can be managed without surgery if the woman is stable and the bleeding is limited.
However, significant internal bleeding can be serious and may require urgent treatment.
Sudden severe abdominal or pelvic pain
Fainting or feeling extremely weak
Dizziness
Rapid heartbeat
Heavy vaginal bleeding
Difficulty breathing
Severe pain associated with vomiting
Increasing abdominal swelling or severe tenderness
If pregnancy is possible, abdominal pain should also be evaluated promptly because an ectopic pregnancy can sometimes present with pain and internal bleeding.
Yes, many hemorrhagic ovarian cysts resolve on their own.
Because many are related to functional ovarian activity, the body can gradually reabsorb the blood and the cyst can disappear.
For women who are stable and have a typical benign-appearing hemorrhagic cyst, doctors may recommend observation and follow-up rather than immediate surgery.
The time required for a cyst to resolve varies.
Your doctor may recommend a repeat ultrasound after an appropriate interval to confirm that the cyst is resolving, particularly when the cyst is larger or its appearance requires follow-up.
Yes. Many hemorrhagic ovarian cysts can be managed without surgery.
Treatment depends on the individual situation.
If the cyst has a typical benign appearance, symptoms are manageable and there are no concerning findings, management may involve:
Observation
Pain relief when appropriate
Follow-up with your gynaecologist
Repeat ultrasound when advised
Surgery may be considered if:
The cyst is causing significant or persistent symptoms
There is significant internal bleeding
The cyst is very large
The cyst does not resolve as expected
The ultrasound appearance is concerning or uncertain
Ovarian torsion is suspected
Another ovarian condition cannot be excluded
The decision should be individualized rather than based on cyst size alone.
No, not every hemorrhagic ovarian cyst needs to be removed.
Many resolve without surgery.
Your gynaecologist may recommend observation when the cyst has a typical appearance of a hemorrhagic functional cyst and there are no concerning clinical features.
Surgery is more likely to be considered when the cyst is persistent, symptomatic, complicated, or has an ultrasound appearance that requires further evaluation.
The goal is to avoid unnecessary surgery while making sure that potentially serious conditions are not missed.
The main investigation is usually pelvic ultrasound.
Depending on the situation, your doctor may recommend:
For women who are comfortable with the procedure and for whom it is clinically appropriate, transvaginal ultrasound can provide detailed images of the ovaries and pelvis.
This may also be used, particularly in certain situations or as part of a combined pelvic ultrasound assessment.
Blood tests may be recommended depending on your symptoms, age, pregnancy possibility and ultrasound findings.
A pregnancy test may be important in women of reproductive age with pelvic pain because pregnancy-related conditions such as ectopic pregnancy need to be considered.
Tumour markers are not automatically required for every ovarian cyst. Their use depends on the patient's age, ultrasound findings and clinical circumstances.
A hemorrhagic cyst can have characteristic ultrasound appearances because of the blood inside it.
Depending on the stage and amount of bleeding, the contents can appear different on ultrasound.
Features that may support a hemorrhagic cyst include:
A cystic ovarian lesion
Internal echoes caused by blood
Patterns that can change as the blood clots and retracts
Absence of certain concerning solid components or vascular features
The appearance can vary depending on when the bleeding occurred.
This is why an ultrasound report should be interpreted by a qualified doctor in the context of your symptoms and clinical history rather than by looking at one phrase in the report alone.
These two conditions can sometimes look similar on ultrasound, but they are not the same thing.
Usually develops when bleeding occurs within a functional ovarian cyst.
It often resolves over time.
An endometrioma is associated with endometriosis, in which tissue similar to the lining of the uterus grows outside the uterus.
An endometrioma can contain old blood and is sometimes called a “chocolate cyst.”
Unlike a typical functional hemorrhagic cyst, an endometrioma generally does not simply disappear within one menstrual cycle.
Follow-up imaging can help distinguish between a resolving hemorrhagic cyst and an endometrioma when the initial ultrasound is not definitive.
A hemorrhagic ovarian cyst is not the same as an endometrioma and does not automatically mean that you have endometriosis.
Both can contain blood and may sometimes have overlapping ultrasound features.
If a cyst does not resolve as expected, has an atypical appearance, or you have symptoms suggestive of endometriosis—such as significant period pain, pain during intercourse, chronic pelvic pain or fertility difficulties—your doctor may consider endometriosis as part of the evaluation.
A simple hemorrhagic ovarian cyst usually does not cause infertility by itself.
Many hemorrhagic cysts are temporary and resolve without affecting the long-term function of the ovaries.
However, fertility can be affected by the underlying condition, rather than by the hemorrhagic cyst itself.
For example, if what appears to be a hemorrhagic cyst is actually an endometrioma, endometriosis may have implications for fertility.
Large, persistent or recurrent ovarian problems may also require more detailed assessment.
If you are trying to conceive and have been diagnosed with an ovarian cyst, discuss your fertility plans with your gynaecologist before deciding on treatment.
Usually, no.
A typical functional hemorrhagic cyst does not necessarily prevent ovulation or pregnancy.
In fact, hemorrhagic cysts can develop around ovulation because of normal ovarian activity.
However, whether you can become pregnant depends on your overall reproductive health, including ovulation, fallopian tubes, sperm factors and the condition of the ovaries.
If you are trying to conceive and have a persistent ovarian cyst, your doctor can advise whether any additional evaluation is needed.
Yes, pregnancy can occur when a woman has a hemorrhagic ovarian cyst.
However, if you have a positive pregnancy test and an ovarian cyst has been found, your doctor may monitor you based on the type and appearance of the cyst.
Some ovarian cysts in early pregnancy can represent the corpus luteum, which normally supports early pregnancy by producing progesterone.
The significance of an ovarian cyst during pregnancy is therefore different from that of a cyst found in a non-pregnant woman.
Treatment depends on the cyst and your symptoms.
This is commonly appropriate for a typical benign-appearing hemorrhagic cyst when the patient is stable.
The cyst may resolve naturally.
If you have pain, your doctor may recommend an appropriate pain-relief medicine based on your individual circumstances.
Do not take medicines during pregnancy or when pregnancy is possible without checking whether they are appropriate for you.
Your doctor may recommend repeat imaging to confirm that the cyst is decreasing or resolving.
Surgery is not routinely required for every hemorrhagic cyst.
It may be considered when there are significant symptoms, complications, persistent or concerning ultrasound findings, or uncertainty about the diagnosis.
There is no proven home remedy that reliably shrinks a hemorrhagic ovarian cyst.
Because many hemorrhagic functional cysts resolve naturally, you may hear that particular foods, drinks, supplements, detoxes or exercises can “dissolve” ovarian cysts.
There is not good evidence that these methods can reliably make a hemorrhagic ovarian cyst disappear.
A healthier approach is to:
Follow the treatment plan recommended by your doctor
Attend follow-up appointments
Take prescribed medicines as advised
Have repeat ultrasound when recommended
Seek medical attention if symptoms become severe
Do not delay medical evaluation in favour of an unproven “natural” treatment.
Hormonal contraception may reduce the formation of some new functional ovarian cysts by suppressing ovulation, but it should not be assumed to rapidly dissolve an existing hemorrhagic cyst.
Whether hormonal contraception is appropriate depends on your contraception needs, medical history and the type of cyst.
Your gynaecologist can discuss whether it is appropriate for you.
Many hemorrhagic functional cysts resolve within several weeks, often by around one or two menstrual cycles.
However, the exact time varies from person to person and depends on the size and nature of the cyst.
If a cyst does not resolve as expected, your doctor may recommend further imaging to determine whether it is truly a hemorrhagic functional cyst or another type of ovarian lesion.
Yes.
A woman who has had one functional ovarian cyst can develop another in the future because functional cysts are related to the normal ovarian cycle.
Having one hemorrhagic cyst does not necessarily mean that you will repeatedly develop them.
If cysts are recurrent, large, painful or persistent, your gynaecologist may evaluate the situation in more detail.
Most hemorrhagic cysts are not emergencies, but complications can occur.
Seek urgent medical attention if you develop:
Sudden severe pelvic or abdominal pain
Fainting or near-fainting
Severe dizziness or weakness
Rapid heartbeat
Heavy bleeding
Severe abdominal tenderness
Persistent vomiting
Sudden severe pain with a known ovarian cyst
These symptoms can occur with complications such as significant bleeding or ovarian torsion and require prompt assessment.
Hemorrhagic Ovarian Cyst: What Should You Remember?
A hemorrhagic ovarian cyst usually develops when bleeding occurs inside a functional ovarian cyst.
The good news is that many are benign and resolve without surgery.
However, the correct approach is not to assume that every ovarian cyst containing blood is harmless. Your doctor considers:
Your age
Symptoms
Cyst size
Ultrasound appearance
Menstrual and reproductive history
Whether the cyst changes over time
Other relevant medical conditions
A cyst that looks like a typical hemorrhagic cyst may simply need observation and follow-up. If the cyst persists, looks unusual, causes significant symptoms or is associated with complications, further evaluation may be necessary.
If you have sudden severe pelvic pain, fainting, severe dizziness, heavy bleeding or other concerning symptoms, seek urgent medical care.
