Understanding your hormone levels is key to managing Polycystic Ovary Syndrome (PCOS). But when you get your lab results, it’s easy to feel confused or even scared. This PCOS hormone levels chart helps you make sense of the numbers—and take back control of your health.
Why Hormone Levels Matter in PCOS
Women with PCOS often have imbalances in key hormones that affect everything from ovulation to skin health. Knowing your hormone levels helps identify the type of PCOS you might have—and how to treat it effectively.
This is especially important if you're managing symptoms like irregular periods, hair loss, or weight gain.

| LH (Luteinizing Hormone) | 1.9–12.5 IU/L | Often elevated | Ovulation |
| FSH (Follicle Stimulating Hormone) | 2.5–10.2 IU/L | Normal or low | Follicle growth |
| Testosterone | 15–70 ng/dL | Elevated | Hair, acne, mood |
| DHEA-S | 35–430 µg/dL | Elevated | Adrenal function |
| Insulin (Fasting) | 2–20 µIU/mL | Elevated | Weight, metabolism |

FAQs About PCOS Hormone Levels
What hormone is most commonly high in PCOS?
Luteinizing hormone (LH) and testosterone are often elevated in women with PCOS. High LH can disrupt ovulation, while high testosterone leads to symptoms like acne or excess hair.
What is a normal LH/FSH ratio for women with PCOS?
A normal LH/FSH ratio is close to 1:1. In PCOS, this ratio is often skewed to 2:1 or higher, meaning LH is disproportionately elevated.
Do high insulin levels mean I have PCOS?
Not necessarily. High insulin is common in PCOS, especially in those with insulin-resistant PCOS, but can also occur in other conditions. A full hormonal profile is best.
Can hormone levels help confirm a PCOS diagnosis?
Yes, hormone levels like LH, FSH, testosterone, AMH, and insulin can support a diagnosis. However, they should be interpreted alongside symptoms and ultrasound findings.
How often should I test my hormones if I have PCOS?
It depends on your treatment plan. Many women test annually or every 6–12 months, but testing may be more frequent if your symptoms change.
