Ovarian Cysts: Symptoms, Types, and Treatment in New York City

An ovarian cyst is a fluid-filled sac that forms on or inside an ovary. Most are completely benign, cause no symptoms, and resolve without any intervention. But some cysts grow larger, cause significant pain, raise concern for an underlying condition such as endometriosis, or develop features that warrant closer evaluation and possibly surgery.

If you have been told you have an ovarian cyst, the most important step is understanding what kind it is, what it is most likely to do, and whether you need treatment or simply careful monitoring. At Kim Gyn on Park Avenue in the Upper East Side, Dr. Kim provides expert evaluation and minimally invasive surgical treatment for ovarian cysts, with a clear focus on preserving your ovarian tissue and long-term fertility.

What Is an Ovarian Cyst?

An ovarian cyst is a fluid-filled sac that develops on or within an ovary. They are extremely common. Most ovarian cysts are functional, meaning they form as a natural part of the menstrual cycle, and the majority resolve on their own within one to three menstrual cycles without any treatment. Some cysts are structural, related to an underlying condition, or develop features that require evaluation and possible surgical removal.

Ovarian cysts are so common that most women will have at least one at some point in their reproductive years. They are frequently discovered incidentally during a pelvic exam or an ultrasound performed for another reason.

The word “cyst” can understandably cause alarm, but the context matters enormously. A small, smooth, fluid-filled cyst found on ultrasound in a woman of reproductive age is almost never cause for immediate concern. A large, complex cyst with irregular features in a postmenopausal woman is a different clinical picture entirely.

What are the Types of Ovarian Cysts?

Accurate classification of the cyst type is the foundation of every management decision that follows.

Functional Cysts

Functional cysts are the most common type. They form directly from the normal activity of the menstrual cycle and are almost always benign.

• Follicular cysts: Each month, a follicle develops inside the ovary to house a maturing egg. Normally, the follicle ruptures at ovulation to release the egg. If it does not rupture, the follicle can continue filling with fluid, forming a follicular cyst. Most resolve within one to two menstrual cycles.
• Corpus luteum cysts: After ovulation, the ruptured follicle transforms into a structure called the corpus luteum, which produces progesterone to support a potential pregnancy. If the opening of the corpus luteum seals over before the fluid inside drains, a cyst forms. These can grow to a significant size and occasionally rupture or bleed, which may cause sudden pelvic pain on one side.

Structural and Pathologic Cysts

These cysts are unrelated to the menstrual cycle. They do not resolve on their own and often require monitoring or removal.

• Endometriomas: Also called “chocolate cysts,” endometriomas are cysts filled with old blood that form as a direct consequence of endometriosis. They develop when endometriosis implants on the ovary and create a blood-filled pocket that grows over time. Endometriomas are clinically important because they can damage the surrounding ovarian tissue, reduce ovarian reserve, and impair fertility. They also carry a small but documented increased risk of certain ovarian cancers and should not be managed with watchful waiting indefinitely.
• Dermoid cysts (mature teratomas): Dermoid cysts form from reproductive cells and can contain a remarkable range of mature tissue types, including hair, skin, sebaceous material, and occasionally teeth or bone. They are almost always benign but are rarely small or functionally inconsequential. They tend to grow slowly, do not resolve on their own, and carry a risk of ovarian torsion due to their weight and size. Surgical removal is typically recommended.
• Cystadenomas: These cysts develop on the outer surface of the ovary and are filled with either a thin watery fluid (serous type) or a thicker mucous-like fluid (mucinous type). They can grow quite large. While most are benign, they require careful ultrasound evaluation and, if large or symptomatic, surgical removal.
• Polycystic ovaries: In polycystic ovary syndrome (PCOS), the ovaries contain multiple small follicular cysts that reflect a hormonal imbalance rather than a structural problem. These are distinct from the cyst types above and are managed through hormonal and metabolic treatment rather than surgery.

Ovarian Cyst Symptoms

Most ovarian cysts cause no symptoms at all and are found only on imaging. When ovarian cyst symptoms do occur, they typically include:

• A dull ache, pressure, or heaviness on one side of the lower pelvis
• A feeling of fullness or bloating in the lower abdomen
• Pain during sexual intercourse, particularly with deep penetration
• Pain that worsens during your period or at ovulation
• Irregular periods, spotting, or a change in your menstrual flow
• Frequent urination or difficulty emptying the bladder fully if a cyst is pressing on the bladder
• Lower back or thigh pain that radiates from the pelvis

Sudden, severe pelvic pain, especially if accompanied by nausea, vomiting, fever, dizziness, or faintness, may signal a ruptured cyst or ovarian torsion. Ovarian torsion occurs when a cyst causes the ovary to twist on its blood supply, cutting off circulation. This is a surgical emergency. If you experience these symptoms, seek care immediately. Do not wait for a scheduled appointment.

Ovarian Cyst Symptoms vs. Normal Pelvic Discomfort

A common source of confusion is distinguishing ovarian cyst symptoms from normal menstrual cramping or mid-cycle pain. The most clinically meaningful signals are pain that is one-sided and persistent, pain that worsens rather than resolves after your period ends, and any episode of sudden severe pain. If you are tracking your cycle and notice that pelvic discomfort does not follow the expected pattern of menstrual cramping, that warrants evaluation.

How are Ovarian Cysts Diagnosed?

Pelvic Examination

A pelvic examination can sometimes detect an enlarged ovary, though smaller cysts are rarely palpable. The exam also provides important clinical context for interpreting imaging findings.

Transvaginal Ultrasound

Ultrasound is the primary and most informative imaging tool for ovarian cysts. A transvaginal ultrasound provides detailed visualization of the ovaries, allowing the specialist to assess the cyst’s size, location, internal structure, wall characteristics, and fluid content. These features are the foundation of the management decision. A simple, smooth-walled, fluid-filled cyst in a premenopausal woman carries a very different clinical implication than a cyst with internal echoes, irregular walls, or solid components.

Pelvic MRI

MRI provides greater soft tissue detail than ultrasound and is used when a cyst has complex features on ultrasound that require further characterization, when endometriosis is suspected, or when surgical planning for complex cases requires more detailed anatomical information.

CA-125 Blood Test

CA-125 is a protein that can be elevated in certain ovarian cancers and also in benign conditions including endometriosis, fibroids, and even normal menstruation. It is not a reliable screening tool for ovarian cancer in premenopausal women and is not appropriate as a standalone diagnostic test. When used in context alongside imaging and clinical findings, it can provide useful supporting information, particularly in postmenopausal patients with concerning cyst features.

Ovarian Cyst Treatment Options

Watchful Waiting

The management of ovarian cysts has evolved significantly over the past two decades. Based on strong clinical evidence and guidelines from the American College of Obstetricians and Gynecologists (ACOG), watchful waiting with serial ultrasound monitoring is now the standard approach for simple, asymptomatic cysts in premenopausal women. The vast majority of these cysts resolve on their own within one to three menstrual cycles.

Watchful waiting does not mean being ignored. It means scheduled follow-up ultrasounds at defined intervals, with clear criteria for escalating to intervention if the cyst grows, develops new features, or fails to resolve within an expected timeframe. The goal is to avoid surgery when it is not necessary while ensuring that cysts requiring treatment are identified promptly.

When is Ovarian Cyst Surgery Recommended?

Surgical intervention is reserved for specific clinical circumstances:

• A cyst that persists beyond three menstrual cycles without resolving
• A cyst that grows significantly on follow-up imaging
• A cyst with complex or suspicious features on ultrasound or MRI
• Significant, ongoing pelvic pain attributed to the cyst
• Clinical concern for ovarian torsion
• An endometrioma, dermoid cyst, or cystadenoma (which do not resolve spontaneously)
• A new cyst in a postmenopausal patient, which requires a more cautious evaluation approach

Laparoscopic Ovarian Cystectomy

Laparoscopic ovarian cystectomy is the standard minimally invasive surgery for ovarian cyst removal. The surgeon removes only the cyst while carefully preserving the surrounding healthy ovarian tissue. This is critically important because it protects the patient’s ovarian reserve, which directly affects both natural fertility and the body’s response to ovarian stimulation for IVF. Ovarian tissue that is removed unnecessarily cannot be restored.

Laparoscopic cystectomy is performed through small incisions in the lower abdomen. A camera (laparoscope) provides magnified visualization of the ovary and surrounding structures. The cyst is carefully separated from the healthy ovarian tissue and removed without rupturing it when possible. The procedure is typically performed as outpatient surgery, with most patients returning home the same day.

All cyst tissue removed during surgery is sent for pathologic analysis to confirm the nature of the cyst and rule out any atypical findings.

What laparoscopic cystectomy involves:

• Three to four small incisions in the lower abdomen, each typically less than one centimeter
• General anesthesia, with the procedure lasting approximately 45 minutes to 1.5 hours depending on cyst size and complexity
• Outpatient surgery in most cases, with discharge home the same day
• Return to light activity within one to two weeks for most patients
• Full recovery typically within two to four weeks

Robotic-Assisted Ovarian Cystectomy

For complex cases involving large cysts, significant adhesions, or concurrent endometriosis, robotic-assisted surgery using the da Vinci system provides enhanced three-dimensional visualization and precision instrument control. Dr. Kim uses robotic assistance selectively, when it offers a meaningful clinical advantage for the complexity of the case.

Oophorectomy: Removal of the Ovary

In a small number of cases, removal of the entire ovary (oophorectomy) may be necessary. This is considered only when the cyst is very large and has replaced so much of the ovarian tissue that there is little functional tissue remaining to preserve, when the blood supply to the ovary has been severely compromised by torsion, or when features of the cyst are sufficiently concerning to warrant removal of the entire structure.

Oophorectomy is not a routine treatment for benign ovarian cysts, and at Kim Gyn, ovarian preservation is the explicit priority whenever it is clinically feasible.

Ovarian Cyst Treatment and Fertility

For patients who are planning to conceive, the surgical approach to ovarian cysts requires particularly careful technique. The goal of laparoscopic cystectomy is to remove the cyst while disturbing as little healthy ovarian cortex as possible, because that cortex contains the follicles that produce eggs.

Endometriomas require special consideration. While surgical removal can relieve symptoms and reduce the risk of progression, surgery on an endometrioma can also reduce the number of remaining follicles in the ovary. This balance between treatment benefit and fertility preservation is a central part of the consultation for any patient who wishes to conceive.

Ovarian Cysts and Endometriosis

Endometriomas, the ovarian cysts caused by endometriosis, deserve specific attention because they are not simply structural cysts. They are a manifestation of a systemic inflammatory disease. Treating the cyst without addressing the underlying endometriosis leaves the root cause untreated and creates a high probability of cyst recurrence.

At Kim Gyn, when endometriosis is identified as the underlying cause of an ovarian cyst, both the cyst and any additional endometriosis implants are treated in the same surgical procedure. This combined approach reduces the likelihood of recurrence and addresses the disease more comprehensively than cyst removal alone.

Questions to Ask Your Ovarian Cyst Specialist

• Based on my ultrasound findings, what type of cyst do I have?
• Given my age, symptoms, and cyst characteristics, is watchful waiting appropriate?
• How often should I have a follow-up ultrasound, and what would prompt earlier action?
• What are the signs of ovarian torsion that should prompt an emergency visit?
• If I need surgery, how will you approach preserving my healthy ovarian tissue?
• Could this cyst be related to endometriosis?
• What impact, if any, could this cyst or its treatment have on my fertility?

Frequently Asked Questions About Ovarian Cysts

What are the most common ovarian cyst symptoms?

Most ovarian cysts cause no symptoms and are discovered incidentally on imaging. When symptoms occur, the most common are a dull ache or pressure on one side of the lower pelvis, bloating, pain during sex, and pelvic discomfort that worsens around the time of ovulation or menstruation. Sudden, severe one-sided pelvic pain may indicate a ruptured cyst or ovarian torsion and requires emergency evaluation.

Do ovarian cysts go away on their own?

Functional cysts, the most common type, typically resolve on their own within one to three menstrual cycles without any treatment. Structural cysts including endometriomas, dermoid cysts, and cystadenomas do not resolve spontaneously and require monitoring or surgical removal. The management approach depends entirely on the type of cyst identified.

Can an ovarian cyst affect my fertility?

It depends on the type and size of the cyst. Functional cysts generally do not affect fertility. Endometriomas can reduce ovarian reserve over time and create an inflammatory environment that impairs conception. Large cysts of any type can compress surrounding ovarian tissue, affecting follicle availability. Your specialist can advise on the specific fertility implications based on your cyst type and individual circumstances.

What is a laparoscopic ovarian cystectomy and how long is recovery?

A laparoscopic ovarian cystectomy is a minimally invasive surgery to remove an ovarian cyst while preserving the surrounding healthy ovarian tissue. It is performed through small incisions using a camera and specialized instruments. Most patients go home the same day. Discomfort typically resolves within one to two weeks, and most women return to normal activities within two to four weeks. Recovery from robotic-assisted surgery for more complex cases may be slightly longer.

Are ovarian cysts cancerous?

The overwhelming majority of ovarian cysts, particularly in premenopausal women, are benign. However, certain ultrasound features, including irregular walls, solid components, internal blood flow on Doppler imaging, and the presence of multiple cysts with complex architecture, can raise concern and warrant further evaluation. New cysts in postmenopausal women are evaluated more carefully. Your specialist will assess the specific characteristics of your cyst and advise on whether additional testing is indicated.

What is the difference between an ovarian cyst and a tumor?

A cyst is a fluid-filled sac. A tumor is an abnormal growth of tissue that can be either solid or mixed. Most ovarian growths found in premenopausal women are cysts. The distinction matters clinically because it guides the management approach. Ultrasound and, when needed, MRI can characterize the internal structure of an ovarian growth and help determine whether it is a simple cyst, a complex cyst, or a solid mass requiring more urgent evaluation.

Can ovarian cysts come back after surgery?

Functional cysts can recur after surgery because they form as part of the normal menstrual cycle. Structural cysts such as dermoid cysts and cystadenomas are unlikely to recur after complete surgical removal. Endometriomas have the highest recurrence rate of any ovarian cyst type, because they are a manifestation of endometriosis, an underlying disease that persists unless fully addressed. Managing the underlying endometriosis reduces but does not eliminate the risk of recurrence.

Do I need surgery for a small ovarian cyst?

Not necessarily. A small, simple, asymptomatic cyst in a premenopausal woman is highly likely to resolve on its own and generally does not require surgery. The decision to operate depends on the cyst’s size, type, ultrasound characteristics, symptoms, and whether it persists or changes on follow-up imaging. ACOG guidelines specifically recommend watchful waiting for simple cysts to avoid unnecessary surgical intervention.
