Understanding Polycystic Ovaries: What They Are and How They Form

Polycystic ovaries are ovaries that contain many small, fluid-filled sacs called cysts. These cysts are actually immature egg follicles. In a typical menstrual cycle, the ovary releases one mature egg during ovulation. However, when ovaries are polycystic, many follicles begin to develop but fail to mature fully. This means ovulation may not happen regularly, or may not happen at all.

The term "polycystic ovaries" refers to the appearance of the ovaries on ultrasound. When a doctor performs a pelvic ultrasound, polycystic ovaries typically show 12 or more follicles that are 2-9 millimeters in size in each ovary, or an ovarian volume greater than 10 cubic centimeters. However, having polycystic ovaries alone does not automatically mean a person has a medical condition. Many people have polycystic ovaries without experiencing symptoms or health problems.

The exact cause of polycystic ovaries is not fully understood. Research suggests several factors may contribute to their development, including insulin resistance, inflammation, and genetic factors. Insulin resistance occurs when the body does not respond properly to insulin, a hormone that controls blood sugar levels. This can lead to higher insulin levels in the blood, which may stimulate the ovaries to produce more male hormones (androgens). Elevated androgen levels can interfere with normal ovulation.

Some studies indicate that inflammation may also play a role. People with polycystic ovaries sometimes show higher levels of inflammation markers in their blood. Additionally, family history appears to matter—if a mother or sister has polycystic ovaries or related conditions, the risk may be higher.

Understanding the basic structure and formation of polycystic ovaries helps people recognize that this is a physical condition with measurable characteristics, not a disease that automatically requires treatment. The presence of polycystic ovaries is a starting point for further evaluation and discussion with healthcare providers about individual symptoms and health needs.

Practical Takeaway: Learn to distinguish between having polycystic ovaries (an ultrasound finding) and having a medical condition that requires treatment. Many people have polycystic ovaries without symptoms or complications.

Recognizing Common Symptoms and Physical Signs

People with polycystic ovaries may experience a range of symptoms, though some have no symptoms at all. The most common symptoms relate to hormonal imbalances and irregular ovulation. One of the most frequently reported symptoms is irregular menstrual periods. Cycles may be longer than normal (more than 35 days between periods), shorter than normal, or may skip months entirely. Some people experience very heavy bleeding during their periods, while others have light spotting.

Elevated androgen levels can cause visible physical changes. Hirsutism, which is excess hair growth in areas where men typically grow hair, affects many people with polycystic ovaries. This includes unwanted hair on the face, chest, back, and abdomen. The hair is often dark and coarse. Acne is another common sign, particularly on the face, chest, and upper back. The acne may be persistent and resistant to standard treatments. Some people also experience male-pattern baldness or thinning hair on the scalp.

Weight management challenges are frequently reported. Research shows that 70-80% of people with polycystic ovaries experience weight gain or have difficulty losing weight, even with diet and exercise. This may be related to insulin resistance—the body requires more insulin to manage blood sugar, and excess insulin can promote fat storage. Weight tends to accumulate around the abdomen.

Other symptoms that some people report include pelvic pain or discomfort, darkening of skin in body creases (a condition called acanthosis nigricans), and skin tags in the neck or armpits area. Mood changes, including depression and anxiety, are also reported by some individuals, though the relationship between polycystic ovaries and mood disorders is still being studied.

Importantly, the severity of symptoms varies greatly. Some people have severe irregular periods and significant hair growth, while others may have only mild symptoms or no symptoms at all. The presence or absence of symptoms does not determine whether someone has polycystic ovaries—diagnosis requires ultrasound findings and sometimes blood tests.

Practical Takeaway: Keep a record of menstrual cycle patterns, skin changes, and hair growth over several months. This information helps healthcare providers understand your individual situation and determine whether further evaluation is needed.

Self-Assessment: Tracking Your Menstrual Cycle and Symptoms

One of the most valuable self-assessment tools is tracking your menstrual cycle. Begin by noting the first day of your period and the last day of bleeding. Count the number of days between the start of one period and the start of the next period—this is your cycle length. A typical cycle ranges from 21 to 35 days. Cycles longer than 35 days or shorter than 21 days are considered irregular. Track your cycle for at least three months to identify patterns.

Create a simple tracking system using a calendar, a notebook, or a smartphone app. Record the following information: the date your period starts, how many days it lasts, how heavy the flow is (light, moderate, or heavy), and any symptoms you experience (cramping, mood changes, breast tenderness). Many free period-tracking apps are available and can help organize this information automatically.

Beyond menstrual tracking, observe other physical changes. Note any changes in hair growth patterns—specifically, do you notice new hair growth on your face, chest, or abdomen? Document where this hair appears and whether it seems to be increasing over time. Take photos of skin changes like acne or darkening patches to track changes over weeks and months. Keep a simple log of your weight if you wish, though remember that weight is just one aspect of health and does not determine whether you have polycystic ovaries.

Mood tracking can also provide useful information. Note any patterns in mood, energy levels, or anxiety. Some people find their mood changes correspond with their menstrual cycle phases. Recording these observations helps you and your healthcare provider identify whether symptoms cluster around certain times in your cycle.

Fertility concerns are another important element to track. If you are attempting to become pregnant, note how long you have been trying. People with polycystic ovaries may have difficulty with conception due to irregular ovulation, but many do conceive naturally. Tracking attempts and any changes helps inform conversations with healthcare providers about your reproductive goals.

Create a summary of your findings after three months of tracking. Note patterns such as "periods every 40-50 days" or "increased facial hair over the past six months" or "difficulty losing weight despite dietary changes." This summary becomes valuable information to share with a healthcare provider during an appointment.

Practical Takeaway: Use a simple tracking method (calendar, notebook, or app) to record menstrual cycle dates, cycle length, flow intensity, and related symptoms for three months. This creates an objective record of your patterns to discuss with your healthcare provider.

Understanding the Connection Between Insulin Resistance and Polycystic Ovaries

Insulin resistance is present in 50-70% of people with polycystic ovaries. Understanding this connection helps explain why certain symptoms occur and why lifestyle modifications may be recommended. Insulin is a hormone produced by the pancreas that helps cells absorb glucose (sugar) from the bloodstream. When insulin resistance develops, the body's cells do not respond properly to insulin signals, so the pancreas produces more insulin to try to achieve the same effect. Over time, blood insulin levels remain elevated throughout the day.

This elevated insulin level stimulates the ovaries to produce excess androgens (male hormones). Androgens interfere with the normal development of egg follicles and can prevent ovulation. Additionally, excess insulin promotes fat storage, particularly around the abdomen, and may increase inflammation in the body. This is why many people with polycystic ovaries and insulin resistance struggle with weight management and why their symptoms may improve with lifestyle changes that improve insulin sensitivity.

Several signs may suggest you have insulin resistance. Acanthosis nigricans—dark, velvety patches of skin, usually in body creases like the neck, armpits, or groin—is a common sign. Weight gain concentrated around the abdomen rather than distributed throughout the body is another indicator. A strong family history of type 2
