What Is PCOS?


Polycystic Ovary Syndrome (PCOS) is a common hormone problem that affects how a woman’s ovaries work. It can cause:


  • Irregular or missed periods

  • Acne or oily skin

  • Weight gain or trouble losing weight

  • Hair growing where you don’t want it (like the chin or chest)

  • Thinning hair on your head


PCOS happens when your body makes more androgens (male-type hormones) than it should. These hormones can stop the ovaries from releasing eggs normally and may also lead to hair loss.


The HARMONIA Study: What Scientists Found


A large study called the HARMONIA Study, published in Fertility and Sterility (September 2025), looked at almost 1,000 women in Finland.

The goal was to see if a simple blood test could replace a more invasive ultrasound to find signs of PCOS in the ovaries.


What They Did


Doctors measured a hormone called Anti-Müllerian Hormone (AMH) in each woman’s blood.They found that women with PCOS had higher AMH levels because their ovaries had more small, immature follicles.


The Key Number


If AMH was 3.2 ng/mL or higher, the test matched ultrasound results 94% of the time!That means the blood test is a reliable, easy way to help diagnose PCOS — no internal exam required.

Why This Matters

This new test gives women a faster, more comfortable way to get answers:


  • Just a blood draw — no ultrasound needed in many cases

  • More accessible for women who can’t easily get specialized care

  • Helps with early treatment to manage symptoms like hair loss, acne, or weight changes


PCOS and Hair Loss

One of the hardest symptoms of PCOS is hair thinning or shedding, especially along the top or crown of the head.


This happens when extra androgens (like testosterone and DHT) make hair follicles smaller and weaker. Over time, hair grows back thinner and shorter.


Other things that can make it worse include:


  • Stress and inflammation

  • Insulin resistance (when your body struggles with blood sugar)

  • Not treating the hormone imbalance early
