Can Ovarian Cyst Cause False Positive Pregnancy Test – Chances Of False Positive Pregnancy Test With Ovarian Cyst

Summary: Ovarian cysts are a common condition in women, often causing discomfort and pain. However, they can also interfere with pregnancy tests, producing false positive results. In this article, we will explore the relationship between ovarian cysts and false positive pregnancy tests, as well as the underlying mechanisms that cause such results. We will also discuss the symptoms of ovarian cysts, the different types of cysts, and available treatment options.

1. What are ovarian cysts and how do they affect pregnancy tests?

An ovarian cyst is a fluid-filled sac that develops in one or both ovaries. These cysts can vary in size and can cause pain, bloating, irregular periods, and other symptoms. In some cases, they can also interfere with pregnancy tests, leading to false positive results. This happens because some ovarian cysts produce human chorionic gonadotropin (hCG), the hormone detected by most pregnancy tests.

HCG is produced by the cells that form the placenta after conception occurs. In a healthy pregnancy, hCG levels double every 48 to 72 hours. However, some types of ovarian cysts can also produce hCG, leading to elevated levels of the hormone in the blood and urine. As a result, a woman taking a pregnancy test may get a positive result even if she is not pregnant.

It is essential to note, however, that not all ovarian cysts produce hCG. The most common types of cysts that can cause false positives are dermoid cysts and cystadenomas. Dermoid cysts are made up of tissue from different parts of the body, such as hair, skin, and teeth, while cystadenomas form on the surface of the ovary and contain mucus or fluid.

2. Symptoms of ovarian cysts

Ovarian cysts can be asymptomatic, meaning they do not cause any noticeable symptoms. However, in other cases, they can be painful and cause discomfort. The symptoms of ovarian cysts may include:

– Abdominal bloating or swelling

– Pelvic pain, especially during menstruation

– Painful bowel movements

– Irregular periods

– Pain during sex

– Nausea or vomiting

– Breast tenderness

It is important to note that some of these symptoms can also be signs of other medical conditions. If you are experiencing any of these symptoms, it’s best to consult your doctor for a diagnosis.

3. Types of ovarian cysts

There are many different types of ovarian cysts, each with its characteristics and causes. Some of the most common types include:

– Functional cysts: These are the most common type of ovarian cysts and are caused by changes in the menstrual cycle. They often go away on their own after a few weeks.

– Endometriomas: These cysts develop in women who have endometriosis, a condition where tissue from the uterine lining grows outside of the uterus and onto other organs in the body.

– Polycystic ovary syndrome (PCOS): This is a hormonal disorder that causes the ovaries to become enlarged and develop multiple cysts.

– Cystadenomas: These cysts form on the surface of the ovary and contain mucus or fluid.

– Dermoid cysts: As mentioned earlier, these cysts are made up of tissue from different parts of the body, such as hair, skin, and teeth.

4. Treatment options for ovarian cysts

In most cases, small ovarian cysts go away on their own and do not cause any complications. However, larger cysts that cause discomfort may require medical treatment. Some of the most common treatment options for ovarian cysts include:

– Watchful waiting: If the cyst is small and asymptomatic, your doctor may recommend monitoring it to see if it goes away on its own.

– Birth control pills: Hormonal birth control can help regulate menstrual cycles and prevent the formation of functional cysts.

– Surgery: If the cyst is large or causing severe symptoms, your doctor may recommend surgery to remove it. In some cases, the affected ovary may also need to be removed.

5. Other causes of false positive pregnancy tests

While ovarian cysts are a common cause of false positive pregnancy tests, there are other factors to consider. Some medications, such as fertility drugs and certain hormonal therapies, can also cause elevated levels of hCG in the blood and urine. In rare cases, some medical conditions, such as trophoblastic disease and certain types of cancer, can also produce hCG and cause a false positive test.

If you’ve taken a pregnancy test and received a positive result, it’s essential to schedule an appointment with your doctor to confirm the pregnancy and rule out any underlying medical conditions.


Ovarian cysts can cause discomfort and pain, but they can also interfere with pregnancy test results, producing false positives. It’s essential to understand the relationship between ovarian cysts and pregnancy tests so that you can take the necessary precautions and seek medical treatment if needed. If you are experiencing symptoms of ovarian cysts or getting false positive pregnancy test results, it’s best to consult your doctor for a proper diagnosis and treatment options.
