Ovarian cysts are a highly common abnormality, affecting approximately 20% of people assigned female at birth . These cysts can occur in the ovaries when a sac containing the oocyte (or egg) fills with fluid, forming a cyst.
Fortunately, most ovarian cysts are painless, benign, and result in no complications for the individuals who get them. In fact, many ovarian cysts are discovered only by happenstance during routine physical exams or imaging procedures.
While most ovarian cyst cases are innocuous, there are some circumstances in which they can pose a danger to health and the ability to conceive. Below, we’ve reviewed the types of ovarian cysts, how they may affect fertility, and what can be done if they develop (to learn more about your ovarian health, consider the Everlywell at-home Ovarian Reserve Test or Women's Fertility Test).
There are three types of “functional” ovarian cysts. Functional cysts are benign and non-disruptive. These include:
For most individuals in their reproductive years, ovarian cysts are naturally resolved by the body and result in no pain, discomfort, or complications.
However, it is possible for ovarian cysts to result in serious complications that call for treatment or even surgical intervention. On rare occasions, ovarian cysts can result in :
The most important risk factor for ovarian cyst complications is age. Individuals past their reproductive years are at a higher risk of developing malignant cysts that can lead to severe consequences, such as ovarian cancer. So if you have ovarian cysts and are going through (or have already been through) menopause, be sure to discuss more rigorous screening options with a healthcare provider.
While most ovarian cysts heal without intervention, those that don’t resolve on their own may impact the ability to conceive.
How exactly can ovarian cyst cause infertility? There are two ways:
Although ovarian cysts can occur on their own, they can also exist as a concurrent symptom alongside other reproductive conditions that may affect fertility and overall health.
Among the most common of these conditions are endometriosis and polycystic ovary syndrome. Let’s explore each of these below.
Endometriosis is a condition that affects between 2 and 10% of American people assigned female at birth in their primary reproductive years. It occurs when endometrial tissue (the tissue that lines the inside of the uterus) grows outside of the uterus. The cysts that arise in individuals with endometriosis are known as endometriomas, though they’re colloquially referred to as “chocolate cysts” because of their dark color.
There are two types of endometriomas:
Often, endometriosis is an extremely painful condition. Common symptoms of endometriosis include:
Despite the severity of some cases of endometriosis, the condition is treatable. People with endometriosis may even take a more aggressive approach to ovarian cyst screening and treatment, with :
Polycystic ovary syndrome, or PCOS, is a medical condition that affects between 5 and 10% of people with uteruses in their reproductive prime . In fact, PCOS is one of the primary causes of female infertility.
Classified as a hormonal disorder, PCOS occurs when the ovaries overproduce androgens, a type of male hormone, which disrupts the ovaries’ ability to grow eggs to maturity and ovulate. In patients, this usually results in at least two of the following outcomes:
While not all people with PCOS develop cysts in their ovaries, all individuals with this condition experience a hormonal imbalance that interferes with the healthy regulation of their reproductive cycles. Some common, noticeable symptoms of this condition include :
The cause of PCOS remains unknown, though a substantial body of evidence suggests high correlations with other conditions. For instance, obesity and insulin resistance, most commonly found in individuals with type II diabetes, are both major risk factors for developing PCOS. Genetics also plays a role, as people who have relatives with PCOS are more susceptible to developing the disorder.
If you’re diagnosed with PCOS, there is at a heightened risk of developing the following comorbidities:
Unfortunately, many people do not discover they have PCOS until they encounter difficulty when trying to conceive .
While there’s currently no cure for PCOS, you can treat the associated symptoms through lifestyle modifications and medication. It’s also important to note that people with PCOS may still conceive.
Apart from age, several other circumstances may increase the likelihood of developing ovarian cysts:
The treatment of ovarian cysts depends on the following key factors:
Depending on the individual, ruptured ovarian cysts may cause mild symptoms or severe pain and bleeding. Severe ruptures may require surgery, but in most cases, ovarian cysts are managed by pain medication and close monitoring to rule out any further complications .
