A normal total testosterone level for a postmenopausal woman falls between 7 and 40 ng/dL, with free testosterone typically ranging from 1.1 to 6.3 pg/mL. These numbers are slightly lower than premenopausal levels (10 to 55 ng/dL for total testosterone), but the drop is more gradual than many women expect.
Why Testosterone Doesn’t Crash at Menopause
Unlike estrogen, which drops sharply during menopause, testosterone declines slowly over decades. The postmenopausal ovary remains hormonally active and accounts for 40% to 50% of testosterone production after menopause. The adrenal glands contribute the rest. This is a key distinction: menopause itself doesn’t trigger a sudden testosterone deficiency the way it does with estrogen.
The picture changes dramatically for women who have had both ovaries surgically removed. That procedure eliminates roughly half of the body’s testosterone supply in one step, causing a marked drop in circulating levels. Adrenal glands partially compensate over time, but they can’t fully replace what the ovaries produced.
How Testosterone Is Tested
Getting an accurate reading matters more in women than in men because the levels are so much lower. Standard immunoassay tests, the kind most commercial labs run, tend to overestimate testosterone at the low concentrations found in women. The gold-standard method is liquid chromatography-tandem mass spectrometry (LC-MS/MS), which performs significantly better at detecting small amounts. If your results seem inconsistent with your symptoms, it’s worth asking whether the lab used this more precise technique.
Most clinicians will order both total and free testosterone. Total testosterone measures everything in your blood, while free testosterone reflects the small fraction (roughly 1% to 2%) that’s unbound to proteins and available for your body to use. A result can fall within the “normal” range for total testosterone while free testosterone runs low, or vice versa, so both numbers together give a clearer picture.
Signs of Low Testosterone
There’s no way to diagnose low testosterone from symptoms alone, since many of these overlap with normal aging, thyroid problems, depression, and the effects of low estrogen. That said, the most commonly reported signs include low sex drive, persistent fatigue, loss of muscle tone and strength, vaginal dryness, thinning hair, difficulty sleeping, and mood changes like depression or anxiety. A blood test is the only way to confirm whether testosterone is actually the issue.
What Testosterone Does for Bone and Muscle
Testosterone plays a protective role in bone health that’s often overlooked. A large cross-sectional study of over 2,100 women aged 40 to 60 found that higher testosterone levels were positively associated with greater bone mineral density in the lumbar spine, even after accounting for other variables like age, weight, and estrogen levels. Women with higher testosterone may carry a lower risk of osteoporosis and fractures later in life.
The mechanism works on two fronts. Testosterone directly slows down the cells that break down bone while supporting the cells that build it. It also converts into estrogen in the body, which provides additional bone-protective and symptom-relieving effects. This dual action helps explain why testosterone matters for skeletal health beyond what estrogen replacement alone can offer. Clinical studies have shown that testosterone supplementation can improve bone density in elderly women with osteoporosis.
When Testosterone Therapy Is Considered
The primary evidence-based use of testosterone therapy in postmenopausal women is for hypoactive sexual desire disorder (HSDD), a condition defined as a persistent lack of sexual desire that causes personal distress. The diagnosis requires that the low desire isn’t better explained by relationship problems, mental health conditions, medication side effects, or another medical issue.
A global consensus statement published in the Journal of Clinical Endocrinology and Metabolism found that testosterone therapy at doses approximating normal premenopausal levels produces meaningful improvements: on average, about one additional satisfying sexual event per month, along with increases in desire, arousal, and orgasmic function, and a reduction in sexual distress. These benefits were demonstrated against placebo in large trials. The same consensus found no evidence that testosterone therapy improves general wellbeing, energy, or mood in women who don’t have HSDD.
How Therapy Is Delivered
Transdermal application, through a cream, gel, or patch applied to the skin, is the recommended delivery method. It produces the most stable, physiological blood levels. Since no testosterone product is approved specifically for women in most countries, clinicians typically prescribe about one-tenth of a standard male dose. In practice, that means a patch releasing 300 micrograms per day, or roughly 5 mg of a 1% testosterone cream applied daily.
If you’re using a male-formulated gel, the typical starting approach is one-tenth of a tube or packet per day, which works out to about three tubes per month instead of 30. Your clinician will check blood levels after a few weeks to make sure you’re landing within the normal premenopausal range, not above it. Injectable testosterone, pellets, and oral formulations are not recommended for women because they tend to produce unpredictable or supraphysiological levels.
Safety Profile
A large claims database analysis comparing women on testosterone therapy to matched controls found no increased risk of major cardiovascular events, blood clots, or breast cancer. In fact, women on therapy had a lower risk of major cardiac events overall, and postmenopausal women specifically showed a significantly lower rate of breast cancer (about half the risk of matched controls). The one consistent side effect was increased facial or body hair growth, which was more common in women receiving testosterone.
These findings apply to physiological doses, meaning amounts that keep blood levels within the normal premenopausal range. Supraphysiological dosing carries different risks, including voice deepening, acne, and clitoral enlargement, which may not fully reverse after stopping treatment. This is why regular blood monitoring and appropriate dosing matter.
