PCOS Ultrasound: What You Need to Know
Your Guide to Understanding the Role of Ultrasound in Diagnosing PCOS
Polycystic Ovary Syndrome (PCOS) is a hormonal imbalance that affects millions of women, particularly those in their reproductive years. While its symptoms can vary from person to person, one key diagnostic tool doctors rely on is an ultrasound. If you’re navigating symptoms or working toward a diagnosis, understanding how a PCOS ultrasound works can help you feel more in control and prepared.
What Is a PCOS Ultrasound?
A PCOS ultrasound helps doctors examine your ovaries to detect changes that may indicate the condition. The scan can reveal multiple small follicles—often described as a “string of pearls”—and an increase in ovarian volume, both of which are common signs of PCOS. This test is safe, non-invasive, and usually takes about 15 to 30 minutes.

Types of PCOS Ultrasound Used
There are two main types of ultrasounds used to assess PCOS:
- Transabdominal Ultrasound: The probe is gently moved across the lower abdomen.
- Transvaginal Ultrasound: A more detailed view is obtained by inserting a probe into the vagina.
Both are widely used, but the transvaginal ultrasound generally offers clearer imaging of the ovaries.
What to Expect During the Procedure
The ultrasound is painless and simple. For abdominal scans, you may be asked to drink water beforehand to fill your bladder. For transvaginal scans, it’s typically best to have an empty bladder unless instructed otherwise. Your doctor will guide you through the process to ensure you’re comfortable.
Frequently Asked Questions
1. Do all women with PCOS have ovarian cysts?
Not necessarily. PCOS is diagnosed based on a mix of symptoms, hormone levels, and ultrasound findings—not just the presence of cysts.
2. Is a transvaginal ultrasound painful?
It might feel a bit uncomfortable, but most women tolerate it well. It provides more detailed images than the abdominal scan.
3. How should I prepare for the scan?
Drink water for an abdominal scan; keep your bladder empty for a transvaginal one unless otherwise instructed.
4. Can ultrasound alone confirm PCOS?
No. Doctors use the Rotterdam Criteria, which include symptoms, hormone levels, and ultrasound findings to make a diagnosis.
5. Is it safe?
Absolutely. Ultrasound uses sound waves, not radiation, making it a safe diagnostic tool.
6. When will I get the results?
Sometimes, results are discussed immediately. In other cases, a follow-up appointment may be scheduled.
Final Thoughts
A PCOS ultrasound can be an important step in understanding your reproductive health. If you’re facing symptoms like irregular periods, unexplained weight gain, or persistent acne, talk to your doctor. Early diagnosis means you can begin exploring treatment options and lifestyle changes that support your well-being.
Remember, you’re not alone—many women face PCOS, and getting the right information is the first step toward managing it effectively.
