Polycystic ovary syndrome (PCOS) affects how your ovaries work and is closely tied to hormone imbalances. One of the most common underlying issues is hyperandrogenism—simply put, having higher-than-normal levels of male sex hormones called androgens, like testosterone.
While everyone produces some androgens, when they climb too high in PCOS, they can trigger a cascade of physical changes and symptoms. Recognizing these signs early can help you have a more productive conversation with your healthcare provider. Below are six of the most telling warning signs that your androgen levels may be elevated.
1. Persistent, stubborn acne
If you're dealing with breakouts that standard over-the-counter cleansers and spot treatments can't seem to touch, elevated androgens could be the culprit. High testosterone increases oil (sebum) production in your skin glands. This excess oil clogs pores and creates an environment where acne-causing bacteria thrive.
The pattern matters, too. Hormonal acne from high androgens often appears along the jawline, chin, and lower cheeks. It tends to be deep, cystic, and painful—not just small whiteheads. If your acne flares up around your period but never fully clears, that's another clue that androgens are driving the cycle.
2. Thinning hair on your scalp (androgenic alopecia)
One of the most distressing signs for many women is noticing that their hair is getting thinner at the crown or temples while the hair on their body seems to be growing just fine. That's because high androgens can shrink hair follicles on your scalp over time in a process called follicular miniaturization.
This type of hair loss is distinct from the temporary shedding you might get after stress or illness. Instead, you may notice a widening part, a more visible scalp at the top of your head, or that your ponytail feels noticeably thinner than it used to. Unlike some other forms of hair loss, androgenic thinning is gradual and progressive without intervention.
3. Unwanted hair growth (hirsutism)
While androgens can weaken the hair on your head, they often stimulate thicker, darker hair growth in areas where men typically grow hair—the face (especially upper lip and chin), chest, back, stomach, and inner thighs. This condition is known as hirsutism.
If you find yourself needing to remove dark, coarse hair from your face or body more frequently, and it feels like it's increasing over time, it's a strong signal that your androgen production is elevated. Hirsutism affects an estimated 70 to 80 percent of women with PCOS who have high androgen levels.
4. Irregular or absent periods
Androgens don't just affect your skin and hair—they directly disrupt your ovulation cycle. High testosterone can interfere with the hormonal signals that trigger your ovaries to release an egg each month. Without regular ovulation, your menstrual cycle becomes unpredictable.
You might go more than 35 days between periods, skip periods for months at a time, or have very light bleeding when you do get your period. Some women with PCOS have fewer than eight periods per year. This isn't just an inconvenience—over time, irregular ovulation is linked to a higher risk of endometrial thickening and other health concerns.
5. Rapid or stubborn weight gain, especially around the midsection
Androgens influence how your body stores fat. When they're too high, your body tends to store more fat around your abdomen rather than in your hips and thighs. This pattern—sometimes called an apple shape—is associated with insulin resistance, which often goes hand-in-hand with PCOS.
You may notice that even when you're eating well and exercising, the weight around your waistline seems resistant to change. Or you might experience sudden weight gain that doesn't seem to match your habits. Abdominal weight gain can also make other PCOS symptoms, like fatigue and acne, feel worse over time.
6. Darkening skin patches (acanthosis nigricans)
Though this symptom is technically caused by insulin resistance rather than androgens directly, it is extremely common in PCOS and often accompanies high androgen levels. You may notice thickened, dark, velvety skin in your body's creases—like the back of your neck, under your arms, in your groin area, or under your breasts.
The skin doesn't hurt or itch, but it becomes noticeably darker and thicker than the surrounding skin. Think of it as a visible sign that your metabolism is under stress alongside your hormones. If you see these patches, it's worth discussing both your androgen levels and your insulin sensitivity with your doctor.
A note on timing: PCOS symptoms can evolve over time. You might have had acne as a teenager that settled down, then notice new hair growth in your 20s or 30s. If any of these signs feel familiar, consider tracking them over a few months before your appointment. Patterns are more useful to a doctor than isolated complaints.
What to do if you suspect high androgens
If several of these warning signs resonate with you, a logical first step is to schedule an appointment with your primary care provider or a gynecologist. They can order blood tests to measure your total and free testosterone, DHEA-S (another androgen), and other markers like sex hormone-binding globulin (SHBG).
There is no single magic pill for everyone, but depending on your test results and your personal health goals, strategies might include lifestyle changes (like a diet lower in refined carbohydrates to help insulin levels) or medications that block or reduce androgen activity. The right approach depends on what's driving your individual imbalance.
Knowing these warning signs doesn't mean you need to panic—it gives you a clear starting point for understanding your body's signals. Hormones are complex, but they do leave tracks. Learning to read them is one of the most empowering things you can do for your long-term health.
