Polycystic Ovary Syndrome (PCOS) affects millions of women in the United States and around the world. This hormone disorder often disrupts menstrual cycles, causes infertility, and brings long-term health risks. Many women live with PCOS for years before getting a diagnosis.
This guide gives you clear, accurate, and expert-backed information on PCOS and how to manage it.

What Is PCOS?
PCOS happens when a woman’s ovaries produce too many male hormones (androgens). This hormonal imbalance interferes with ovulation and causes small fluid-filled sacs (cysts) to grow in the ovaries.
Common features of PCOS:
- Irregular or missed periods
- Higher androgen levels
- Enlarged ovaries with multiple small cysts
PCOS affects up to 5 million women in the U.S., according to the CDC. It remains a major cause of infertility and raises the risk of diabetes and heart problems.

How PCOS Impacts Reproductive Health
Your reproductive system depends on balanced hormones and regular ovulation. PCOS throws this off. If you don’t ovulate each month, you may:
- Have fewer chances to get pregnant
- Develop irregular periods
- Experience thickening of the uterine lining
Lack of ovulation reduces progesterone, leading to irregular or absent periods. Over time, this can increase the risk of endometrial cancer.
Many women first find out they have PCOS when they struggle to get pregnant.
Main Symptoms of PCOS
PCOS symptoms vary from person to person. The most common signs include:
- Irregular or missed periods
- Excess facial or body hair
- Acne or oily skin
- Thinning scalp hair
- Weight gain or trouble losing weight
- Dark patches on the skin
- Trouble conceiving
- Fatigue or mood swings
Some women have mild symptoms. Others face several at once.
What Causes PCOS?
Doctors haven’t pinpointed a single cause, but several factors play a role.
1. Insulin Resistance
Many women with PCOS have insulin resistance. This means their cells don’t respond properly to insulin, causing higher insulin levels and more androgen production.
2. Genetics
PCOS often runs in families. If your mom or sister has it, your risk increases.
3. Hormonal Imbalance
Excess androgens block ovulation and cause symptoms like acne and excess hair.
4. Chronic Inflammation
Low-grade inflammation may also raise androgen levels. Doctors sometimes see high CRP (C-reactive protein) in PCOS patients.
How Doctors Diagnose PCOS
There’s no single test for PCOS. Doctors rely on the Rotterdam Criteria, which require at least two of these:
- Irregular or no ovulation
- High androgen levels (via blood test or visible signs)
- Polycystic ovaries on ultrasound
Doctors may:
- Ask about symptoms
- Run hormone and glucose blood tests
- Perform a pelvic ultrasound
- Do a physical exam
Early diagnosis makes treatment easier and helps prevent complications.
How PCOS Affects Fertility
Ovulation is key to getting pregnant. PCOS often stops regular ovulation, making it harder to conceive. But PCOS doesn’t mean you can’t get pregnant. Many women with PCOS have healthy pregnancies with the right support.
Doctors often recommend:
- Lifestyle changes (diet, weight loss)
- Ovulation-stimulating medications
- Fertility treatments like IUI or IVF
How to Treat and Manage PCOS
There’s no cure for PCOS, but treatment can control symptoms and improve your quality of life.
1. Lifestyle Changes
Most doctors start here.
- Healthy diet: Eat more vegetables, whole grains, lean proteins, and healthy fats. Cut back on sugar and refined carbs.
- Exercise: Aim for at least 30 minutes a day. Movement helps regulate insulin and hormones.
- Weight management: Losing even 5%–10% of your weight can help restore ovulation.
2. Medications
- Birth control pills: Regulate periods and reduce male hormone levels.
- Metformin: Improves insulin sensitivity and may help restore ovulation.
- Letrozole or Clomid: Encourage ovulation in women trying to get pregnant.
- Spironolactone: Helps with acne and excess hair by blocking androgens.
3. Fertility Support
If ovulation meds don’t work, doctors may suggest:
- IUI (Intrauterine Insemination): Sperm placed directly in the uterus
- IVF (In Vitro Fertilization): Fertilization outside the body
- Ovarian drilling (rare): A procedure to help restore ovulation
Mental and Emotional Impact
PCOS affects more than the body. It can take a toll on your mental health. Many women report:
- Depression
- Anxiety
- Low self-confidence
- Negative body image
If you feel overwhelmed or down, talk to a mental health provider. You’re not alone, and help is available.
Long-Term Health Risks of PCOS
Without treatment, PCOS increases your risk for:
- Type 2 diabetes
- High blood pressure
- High cholesterol
- Heart disease
- Sleep apnea
- Endometrial cancer
Managing PCOS now protects your health later.
When to See a Doctor
Reach out to your healthcare provider if you:
- Miss periods or have irregular cycles
- Try to get pregnant without success
- Notice extra hair growth or acne
- Struggle with weight or low energy
The earlier you get help, the better your outcome.
