Hearing that you have an ovarian cyst can be unsettling, especially if you are hoping to start or grow your family. The good news is that the vast majority of ovarian cysts are harmless, come and go on their own, and have no effect on your fertility. Let us walk through what is true, what is myth, and when a cyst is worth a closer look.
What Exactly Is an Ovarian Cyst?
An ovarian cyst is a fluid-filled sac that forms on or inside an ovary. They are extremely common, and most women will develop at least one during their lifetime, often without ever knowing it. Many cysts cause no symptoms at all and are discovered by chance during a routine pelvic exam or an ultrasound done for another reason.
The most common type is a functional cyst, which forms as a normal part of the menstrual cycle. Each month your ovary grows a small follicle that releases an egg. Sometimes that follicle does not release the egg, or it seals back up and fills with fluid afterward. These functional cysts are a sign that your ovaries are doing exactly what they are supposed to do, and they typically disappear on their own within one to three menstrual cycles.
Do Ovarian Cysts Affect Fertility? Myths vs. Facts
This is the question we hear most often, and the answer is reassuring for the majority of women. Let us separate the common myths from the facts.
- Myth: All ovarian cysts hurt your chances of getting pregnant. Fact: Most cysts, especially functional ones, have no impact on fertility whatsoever and resolve without any treatment.
- Myth: A cyst means you need surgery before you can conceive. Fact: The great majority of cysts never need surgery. Many providers simply monitor them over a few cycles to confirm they shrink and disappear.
- Myth: Cysts always mean something is seriously wrong. Fact: Simple, fluid-filled cysts found on ultrasound are almost always benign.
- Myth: If you have ever had a cyst, you will struggle to conceive. Fact: A single functional cyst in the past tells us very little about your future fertility.
The truth is that cyst type matters far more than the simple presence of a cyst. Some types can affect fertility, and those are the ones worth understanding.
Which Types of Cysts Can Affect Fertility?
While functional cysts are almost always harmless, a smaller group of cysts and ovarian conditions can play a role in fertility. These are the ones your provider pays closer attention to.
- Endometriomas: These cysts form when endometriosis, tissue similar to the uterine lining, grows on the ovary. Endometriomas are associated with endometriosis, which is a recognized cause of fertility challenges. The inflammation and scarring linked to endometriosis, rather than the cyst alone, can interfere with conception.
- PCOS-related cysts: Polycystic ovary syndrome (PCOS) involves multiple small follicles on the ovaries along with a hormonal imbalance. The hallmark of PCOS is irregular or absent ovulation, and difficulty ovulating is one of the most common reasons women with PCOS may take longer to conceive. The small follicles seen on ultrasound are part of the picture, but the ovulation issue is what affects fertility.
- Large or complex cysts: A cyst that grows large, contains solid areas, or has an unusual appearance on ultrasound may need closer evaluation and sometimes removal. Large cysts can occasionally interfere with normal ovarian function, and removing them is sometimes done with fertility in mind.
- Dermoid cysts and cystadenomas: These are typically benign but can grow over time. They rarely affect fertility directly, though larger ones may be removed to protect the ovary and reduce the risk of complications like twisting.
If you have one of these conditions, it does not mean pregnancy is off the table. Many women with endometriosis or PCOS go on to conceive, sometimes naturally and sometimes with support. The key is an accurate diagnosis and a plan tailored to you.
What Symptoms Should I Watch For?
Many cysts cause no symptoms. When they do, you might notice:
- A dull ache or pressure on one side of your lower abdomen or pelvis
- Bloating or a feeling of fullness
- Pain during intercourse
- Changes in your menstrual cycle, such as irregular or heavier periods
- Discomfort with bowel movements or a frequent urge to urinate
These symptoms can have many causes, so the right next step is an evaluation rather than guesswork.
When Should I Be Evaluated?
It is a good idea to schedule an appointment if you notice persistent pelvic pain, changes in your menstrual cycle, a cyst that does not resolve over a few cycles, or if you have been trying to conceive for a year without success (or six months if you are over 35). Your provider may recommend a pelvic ultrasound to look at the size and type of cyst, and sometimes blood work to check hormone levels.
Certain symptoms point to a possible emergency and should never wait. Go to the emergency room or call 911 if you experience:
- Sudden, severe, or sharp pelvic or abdominal pain
- Pain accompanied by fever or vomiting
- Faintness, dizziness, or weakness
- Rapid breathing or a racing heart
These can be signs of a cyst that has ruptured or caused the ovary to twist, known as ovarian torsion, both of which need prompt care.
