Questions, answered

PCOS (polycystic ovary syndrome) is a common hormonal condition affecting an estimated 6 to 13 percent of women of reproductive age. The CDC cites roughly 6 to 12 percent, and the 2023 International Evidence-based Guideline puts the figure at about 8 to 13 percent. It is characterized by irregular periods, higher androgen levels, and, in some women, polycystic ovaries seen on ultrasound. It is one of the most common endocrine conditions in women and a leading cause of infertility.

The most common symptoms include irregular or missed periods, excess hair growth (hirsutism), acne, and difficulty losing weight. According to ACOG, many women with PCOS also have insulin resistance. Other symptoms can include male-pattern hair thinning, patches of darkened skin (acanthosis nigricans), and mood changes.

PCOS is typically diagnosed using the Rotterdam criteria, which require two of three features: irregular ovulation, clinical or biochemical signs of high androgens, or polycystic ovaries on ultrasound. The 2023 International Evidence-based Guideline also allows an elevated anti-Mullerian hormone (AMH) blood test as an alternative to ultrasound in adults. Blood tests can check hormone levels, and the process also involves ruling out other conditions such as thyroid disorders. Only a qualified clinician can diagnose PCOS.

PCOS is believed to result from a combination of genetic and environmental factors, and the exact cause is still not fully understood. Research shows that insulin resistance plays a central role for many women with PCOS, regardless of weight. A family history of PCOS appears to increase the likelihood of developing it.

Insulin resistance is common in PCOS, and higher insulin levels can stimulate the ovaries to produce more androgens. Elevated insulin can also make weight management harder for some women. The link is well recognized, which is why insulin-sensitizing approaches, including the medication metformin, are sometimes part of a clinician-directed treatment plan.

Yes. Lifestyle changes are considered a first-line approach for PCOS, and studies suggest that modest weight loss of around 5 to 10 percent can improve symptoms for many women. Research also indicates that combining a lower-glycemic eating pattern with regular exercise may improve insulin sensitivity and support more regular ovulation. Notably, exercise can improve insulin sensitivity even without weight loss.

PCOS is a leading cause of ovulation-related infertility, because it can disrupt regular ovulation. However, many women with PCOS conceive, often with the help of lifestyle changes, ovulation-supporting medications, or assisted reproductive care. Fertility questions are best discussed with your healthcare provider.

Over time, PCOS is associated with a higher risk of type 2 diabetes, cardiovascular risk factors, and, because of infrequent periods, changes in the uterine lining. PCOS is also associated with a higher likelihood of sleep apnea, depression, and anxiety. Working with a clinician on lifestyle and, when appropriate, medical care can help reduce these long-term risks.

PCOS looks different from person to person, and the factors driving it, such as insulin, inflammation, stress, or post-pill recovery, can differ too. Identifying which factors appear most relevant for you helps focus your nutrition, movement, and supplement guidance on what is likely to matter most. It is a personalization lens, not a medical classification.

Yes. In May 2026, an international consensus published in The Lancet renamed polycystic ovary syndrome to PMOS, polyendocrine metabolic ovarian syndrome, because the condition is metabolic and endocrine, not only ovarian. Most women, clinicians, and search engines still say PCOS, so that is the name we lead with. PCOS Lens covers both: same condition, same app, whichever name you were given.

Yes. Many people take the assessment while they are still trying to understand symptoms that may be related to PCOS. It can help you organize what you are experiencing and give you clearer talking points for a conversation with a healthcare provider. It does not diagnose PCOS or any other condition.

Daily tracking gives the clearest picture, but even a few times a week is useful. The more consistently you log, the easier it becomes to see patterns in your energy, mood, sleep, and symptoms over time.

The assessment is built on questions informed by mainstream PCOS research, and it is designed to give you a wellness insight, not a diagnosis. It highlights which factors appear to be driving your symptoms and shows a full distribution rather than forcing you into a single rigid pattern. Use it to guide your habits and to inform a conversation with your healthcare provider, not to replace one.

Your privacy is a priority. Your data is encrypted in transit, it is never sold to advertisers or data brokers, and it is never shared with third parties without your explicit consent. You stay in control: you can export your data or delete your account and its data at any time.

PCOS Lens is built for US women who are tired of generic advice and dismissive appointments. Instead of one-size-fits-all tips, it identifies what appears to be driving your symptoms and turns that into a plan you can follow every day, free while we grow, with no appointment and no glucose monitor required. The guidance is evidence-aligned with visible citations, and we never sell your health data.

Yes. You can export your tracking history to take with you, which is useful for sharing with a healthcare provider or keeping your own records. You can also delete your data at any time.

Nothing. PCOS Lens is free during early access, and every feature is included with an account: your assessment and full result, your nutrition, movement, and supplement plans, the AI coach, photo meal scans, daily tracking, and symptom insights. There is no card to enter and no trial to keep track of. We may add an optional paid tier one day. If we do, we will tell you first, any price will be shown clearly before you pay, and nobody is charged without signing up for a paid plan. Viewing and exporting the data you have logged will always be free.

No. The four drivers, insulin, inflammation, stress and adrenal, and post-pill recovery, are a personalization lens we use to tailor your plan, not a clinical diagnosis. They are different from the medical Rotterdam phenotypes your doctor may use. Most people are a mix, so we show a dominant driver alongside secondary factors rather than labeling you as a single fixed pattern.

Voice features let you log symptoms by speaking and hear spoken replies from the AI coach. By default, speech recognition runs on your own device using your browser's built-in capabilities, so your voice is processed locally where supported. As with the rest of the app, your health data is encrypted in transit and never sold.
