Understanding the testosterone normal range is essential for evaluating your hormonal health. Testosterone is the main androgen (sex hormone) in the body, measured from a morning blood sample in nanograms per decilitre (ng/dL). In adult men a normal total testosterone sits roughly between 300 and 1000 ng/dL; in adult women the normal range is far lower, about 8 to 70 ng/dL. Because male and female ranges differ by an order of magnitude, your result is always read against your own sex.
What is Testosterone, Total?
Testosterone is produced mainly in the testes in men and in smaller amounts by the ovaries and adrenal glands in women. It drives many things beyond reproduction: muscle and bone strength, red blood cell production, mood, energy and libido. A total testosterone test measures all the testosterone in your blood, both the fraction bound to proteins and the small free fraction that is biologically active.
A doctor may order this test for different reasons depending on your sex. In men, it is usually checked when there are symptoms of low testosterone, such as low sex drive, fatigue, loss of muscle, low mood or difficulty getting an erection. In women, it is more often ordered to investigate signs of excess androgen, such as irregular periods, acne, or unwanted hair growth. Testosterone is best measured in the morning, when levels peak, and an abnormal value is confirmed on a repeat sample before any conclusion is drawn.

Testosterone normal range
For most adults, the general reference range used by Indian and international laboratories treats a total testosterone of roughly 300-900 ng/dL as normal, with values above or below graded by how far they fall from that band. The table below shows the general (non-sex-specific) tiers. Remember that this is a starting point only: the sex-specific ranges in the next section are what actually apply to you, and units are always ng/dL.
Total testosterone (ng/dL) | How it is read |
|---|---|
Below 100 | Critically low |
100-199 | Severely low |
200-249 | Moderately low |
250-299 | Borderline low |
300-900 | Normal |
901-1200 | Borderline high |
1201-1500 | Moderately high |
These bands follow the Endocrine Society's framework for interpreting testosterone. Different laboratories may print slightly different reference limits depending on their assay, so always read your value against the range on your own report.
Normal range by age, sex and condition
Testosterone is one of the few lab values where sex changes everything. The male and female normal ranges do not overlap and are interpreted from completely different reference tables. The values below come from standard adult male and adult female laboratory reference ranges, combined with the Endocrine Society's hypogonadism criteria in men and the Rotterdam criteria for hyperandrogenism in women.
Group | Normal total testosterone (ng/dL) | Why it differs |
|---|---|---|
Adult men | 300-1000 | The testes produce large amounts of testosterone, so the healthy range is high. A value below roughly 300 ng/dL is the usual threshold that prompts a doctor to consider low testosterone. |
Adult women | 8-70 | Women make only small amounts from the ovaries and adrenal glands, so the whole range is about ten times lower than in men. Here the concern is usually a value that is too high. |
Older men | 300-1000 (often in the lower part) | Testosterone in men declines slowly and naturally with age, so healthy older men often sit toward the lower end of the range. Age alone is not treated as a disease, but symptoms plus a low reading are assessed together. |
Women with suspected PCOS | Above ~70-100 flags hyperandrogenism | Under the Rotterdam criteria, a raised total testosterone is a key sign of polycystic ovary syndrome, alongside irregular periods and features such as acne or excess hair. |
Because the ranges sit so far apart, a result that would be alarmingly low for a man is completely normal for a woman, and a value that is normal for a man would be extremely high for a woman. This is exactly why a lab report always states the reference range for your recorded sex.

What high Testosterone means
High testosterone matters most in women, where it is a central feature of hyperandrogenism. In adult women, a value above roughly 70 ng/dL is read as borderline high, above about 100 as moderately high, and above 150 as severely high. The most common cause is polycystic ovary syndrome (PCOS), which the Rotterdam criteria define using a combination of raised androgens, irregular or absent ovulation, and polycystic ovaries on ultrasound. PCOS is very common among Indian women and often shows up as irregular cycles, acne, oily skin, scalp hair thinning, or unwanted facial and body hair. Less commonly, high androgens can come from adrenal disorders or certain ovarian conditions, which your doctor will consider if the level is markedly elevated.
In men, a genuinely high total testosterone (above about 1000-1200 ng/dL) is uncommon and is most often explained by testosterone supplements or anabolic steroid use rather than a natural cause. A doctor interprets any high value in the context of symptoms and a repeat, morning sample.
What low Testosterone means
Low testosterone is chiefly a concern in men. In adult men, values are graded as borderline low (250-299 ng/dL), moderately low (200-249), severely low (100-199) and critically low (below 100). The Endocrine Society defines male hypogonadism as a total testosterone below the lower reference limit, commonly around 300 ng/dL, measured on at least two separate morning fasting samples, together with consistent symptoms. That symptom requirement is important: a single low number without symptoms is not enough to make the diagnosis.
Symptoms that may accompany low testosterone in men include reduced sex drive, erectile difficulty, fatigue, low mood, loss of muscle mass and strength, and reduced body hair. Causes range from problems in the testes themselves to signals from the pituitary and hypothalamus, and levels can also be temporarily lowered by acute illness, obesity, poor sleep and some medications, which is why confirmation on a repeat morning sample matters. In India, low testosterone in men is often under-discussed, and symptoms are sometimes dismissed as "just stress" rather than investigated. In women, a low testosterone level is generally not treated as a problem on its own.
How to manage or improve your Testosterone
Whether your result is high or low, the first step is confirming it correctly: a morning sample, repeated, interpreted against your sex-specific range and your symptoms. Lifestyle habits genuinely influence hormone balance and support any treatment your doctor recommends:
Aim for a healthy weight. Excess body fat is closely linked to both low testosterone in men and androgen excess in women with PCOS, so gradual, sustainable weight management often helps in both directions.
Move regularly. A mix of strength work and everyday activity supports muscle, mood and metabolic health. In women with PCOS, regular exercise can improve insulin sensitivity, which is closely tied to androgen levels.
Prioritise sleep. Testosterone is produced during sleep, and short or disrupted sleep can lower morning levels in men.
Eat a balanced, whole-food diet. An Indian plate built around dals and legumes, vegetables, whole grains like millets and brown rice, fruit, nuts and adequate protein supports metabolic health. For women managing PCOS, reducing refined carbohydrates and sugary foods can help with insulin resistance.
Limit alcohol and avoid unprescribed hormone products. Over-the-counter "testosterone boosters" and anabolic steroids can disrupt your natural hormones and distort test results.
When to see a doctor: Men with ongoing fatigue, low libido, erectile problems or loss of muscle, and women with irregular periods, persistent acne or unwanted hair growth, should get testosterone checked rather than self-treating. Never start testosterone therapy or supplements on your own; both the diagnosis and any treatment need medical supervision.

Frequently asked questions
What is a normal testosterone level?
In adult men, a normal total testosterone is roughly 300 to 1000 ng/dL. In adult women it is far lower, about 8 to 70 ng/dL, because women naturally produce much less of the hormone.
Why should testosterone be tested in the morning?
Testosterone levels peak in the early morning and fall through the day, so a morning sample gives the most reliable reading. Doctors also confirm an abnormal result on a repeat morning test before drawing conclusions.
What testosterone level indicates low testosterone in men?
The Endocrine Society commonly uses a total testosterone below about 300 ng/dL, found on at least two morning fasting samples and accompanied by consistent symptoms, to consider a diagnosis of male hypogonadism.
What does high testosterone mean in women?
In women, a raised testosterone is a key sign of hyperandrogenism and is often linked to polycystic ovary syndrome (PCOS) under the Rotterdam criteria, especially alongside irregular periods, acne or excess hair.
Does testosterone fall with age in men?
Yes. Testosterone in men declines slowly and naturally with age, so many healthy older men sit toward the lower part of the normal range. Age alone is not a disease, and results are judged together with symptoms.
Can lifestyle changes affect testosterone?
Lifestyle can help. Maintaining a healthy weight, regular exercise, good sleep and a balanced diet support healthy hormone levels in men and can improve androgen balance in women with PCOS, but any treatment should be guided by your doctor.
