Overview

Polycystic Ovary Syndrome (PCOS): Please check these three things first

  • PCOS is diagnosed by comprehensively evaluating menstrualovulation irregularity, signs of androgen excess, and ovarian morphology, while excluding similar causes.
  • A finding of many follicles on an ultrasound or AMHa single result showing high levels does not alone confirm a diagnosis of PCOS.
  • Ovulation and menstrual management goals vary depending on pregnancy plans, and metabolic health, such as blood pressure and blood sugar, is also checked.

Meaning and Distinctions

What is Polycystic Ovary Syndrome (PCOS)?

Easily confused terms
It cannot be determined solely by the finding of many follicles on an ultrasound.
Why this is checked during medical evaluation
Treatment goals for the cycle, metabolism, and ovulation vary depending on whether there are pregnancy plans.
What to record for your visit
If you have not had a period for a long time, please confirm whether you are pregnant before seeking medical evaluation.

Connecting PCOS to my symptoms

Check diagnostic characteristics and other potential causes together

In adults, we check for characteristics such as irregular menstruation/ovulation, signs of androgen excess (like blood tests or hirsutism), and ovarian morphology. Causes that create similar menstrual changes, such as thyroid or prolactin abnormalities, must also be distinguished. Since adult criteria are not applied directly to adolescents, please consult a medical professional regarding age and the progress since the first period.

Record the menstrual interval and current goals together

Please prepare the start dates of your periods for the last 6-12 months, the longest interval, changes in acne, hirsutism, or scalp hair loss, and test results for weight, blood pressure, and blood sugar. Depending on whether you want to conceive immediately or manage your period regularly, the tests and treatment goals may differ. If you are taking contraceptives or supplements, please provide the name and start date.

Frequently Asked Questions

Common questions when looking into PCOS

If I am told I have polycystic ovaries on an ultrasound, does that mean I have PCOS?

They do not mean the same thing. Ovarian morphology is just one of the characteristics used for diagnosis; menstrual/ovulation patterns, androgen-related findings, and other causes must be checked together.

If my periods are irregular but I have no plans for pregnancy, is it okay to wait?

If you have not had a period for a long time or the interval continues to lengthen, you must check the cause, endometrial protection, and metabolic health regardless of pregnancy plans. Please seek medical evaluation with a record of your last period date and cycle.
