If you’ve been searching “low testosterone in women” because the fatigue, low libido, and brain fog don’t add up to a normal “busy season,” you’re asking the right question — testosterone isn’t just a men’s hormone, and low levels in women are real, measurable, and often overlooked. Here’s what actually causes it, what the evidence says about treatment, and how we evaluate it at Total Medical & Wellness.
The Quick Answer
Women produce testosterone too — in the ovaries and adrenal glands — and levels decline gradually with age, then more sharply around menopause. Low testosterone is most clearly linked to decreased sex drive, but it’s also associated with fatigue, low mood, reduced muscle mass, and brain fog. The honest evidence-based answer on treatment: testosterone therapy has the strongest clinical support for low sexual desire in postmenopausal women. Evidence for treating fatigue, mood, or energy alone is weaker, so at Total Medical & Wellness we start with real bloodwork and a full symptom picture — not a shot based on how you feel in one visit.
What Does Low Testosterone in Women Actually Feel Like?
Testosterone plays a bigger role in women’s health than most people realize. When levels drop below what’s normal for your age, common signs include:
- Decreased sex drive or low libido
- Persistent fatigue or low energy
- Low mood or lack of motivation
- Decrease in muscle mass and strength
- Decrease in bone density over time
- Brain fog or trouble concentrating
- Vaginal dryness
These symptoms overlap heavily with low estrogen and progesterone, which is exactly why an accurate diagnosis needs a full hormone panel — not a guess based on one symptom.
What Causes It?
Age is the most common driver, but several other factors can lower testosterone in women:
- Menopause and perimenopause. By menopause, testosterone levels may have declined to roughly half of what they were in a woman’s 20s.
- Ovarian dysfunction or surgical removal (oophorectomy). Since the ovaries produce a significant share of the body’s testosterone, removing or impairing them causes a sharp drop.
- Long-term use of oral birth control or corticosteroids. Both can suppress natural androgen production.
- Pituitary or adrenal gland disorders. These glands help signal hormone production, so dysfunction here can lower testosterone indirectly.
- Chronic low-calorie dieting or very low body fat. Hormone synthesis depends on adequate energy intake.
Does Testosterone Therapy Actually Work for Women?
Here’s the honest, evidence-based answer, not the sales pitch: the strongest clinical evidence for testosterone therapy in women is for treating hypoactive sexual desire disorder (HSDD) — persistent low sexual desire that causes distress — in postmenopausal women. Multiple clinical trials have shown transdermal testosterone improves sexual desire and activity in this specific group.
For other symptoms — fatigue, mood, cognitive function, general well-being — the evidence is much thinner. The Endocrine Society’s clinical practice guideline specifically recommends against routine testosterone prescribing for those reasons alone, citing a lack of long-term safety and efficacy data. That doesn’t mean testosterone can’t be part of a broader hormone plan — it means it should be prescribed based on your actual labs and symptoms, not marketed as a universal energy fix.
It’s also worth knowing that no testosterone product is currently FDA-approved specifically for women in the United States. When testosterone is appropriate, it’s typically compounded or prescribed off-label at low, physiologic (female-range) doses under a provider’s supervision — which is why lab-guided dosing and monitoring matter.
How We Evaluate and Treat It at Total Medical & Wellness
We treat testosterone as one piece of a full hormone picture, not a standalone fix. Our process:
- Consultation & symptom review. We discuss your symptoms, cycle history, and health goals in detail.
- Full hormone panel. Comprehensive labs evaluate estrogen, progesterone, and testosterone together — not testosterone in isolation.
- Customized BHRT protocol. If testosterone is appropriate, it’s combined with the right estrogen/progesterone support, using bioidentical hormones dosed to your biology. Delivery options include creams, troches, or pellets.
- Monthly check-ins. Follow-up labs and dose adjustments to keep you in a safe, appropriate range — not guessing and hoping.
Is It Safe? What to Watch For
At appropriate, lab-guided doses, testosterone therapy is generally well tolerated. Because testosterone is a potent hormone, your provider monitors for signs of androgen excess, which can include acne, oilier skin, or unwanted hair growth. This is exactly why we don’t prescribe testosterone off a single visit or symptom checklist — ongoing monitoring is part of the protocol, not an afterthought.
Frequently Asked Questions
Is testosterone only a men’s hormone?
No. Women produce testosterone in the ovaries and adrenal glands, and it plays a real role in libido, energy, muscle mass, and bone density — just at much lower levels than in men.
How do I know if my testosterone is actually low?
The only reliable way is a blood test interpreted alongside your symptoms and age — not a symptom checklist alone, since fatigue, low mood, and low libido overlap with several other hormone imbalances.
Will testosterone therapy make me build muscle like a man or grow facial hair?
Not at the low, female-range doses used in BHRT under proper monitoring. Androgen-excess side effects like unwanted hair growth or acne are a sign the dose needs adjusting, which is exactly why we recheck labs regularly rather than setting a dose and walking away.
Do I need a full hormone panel, or can I just test testosterone?
We test the full picture — estrogen, progesterone, and testosterone together. Since symptoms overlap so heavily, treating testosterone alone without seeing the rest of your hormone levels can miss the actual cause.
Is testosterone therapy for women covered by insurance?
Coverage varies by plan and is typically limited for compounded or off-label hormone therapy. We offer both insurance and cash-pay options for labs and consultations — call us to discuss what applies to your situation.
