Testosterone, Total: what your level actually means
Also known as: Total Testosterone, Serum Testosterone · Updated 19 Aug 2026 · Educational — not medical advice
The short answer: Total testosterone in adult men typically falls between about 300 and 1000 ng/dL, and levels naturally decline gradually with age starting around the mid-30s to 40s. Women have a much lower normal range, roughly 15 to 70 ng/dL, so results are always interpreted against the reference range for the person's sex. A single low or high reading is often repeated, ideally with an early-morning sample, since testosterone follows a daily rhythm and peaks around that time.
Where does your value sit?
This Testosterone, Total value is inside the normal range. Your lab's printed reference range takes precedence — ranges vary slightly between laboratories.
What Testosterone, tells you
Testosterone is the primary male sex hormone, made mainly by the testes in men and in smaller amounts by the ovaries and adrenal glands in women. It plays a role in muscle mass, bone density, mood, and sexual function in both sexes, though the amounts and typical ranges differ substantially between men and women. (Illustration is schematic.)
Common reasons it rises
- Anabolic steroid or testosterone therapy use — supplementing or misusing testosterone directly raises blood levels.
- Certain testicular or adrenal tumors — rare, but can overproduce testosterone.
- Polycystic ovary syndrome — in women, this condition commonly raises testosterone above the typical female range.
- Congenital adrenal hyperplasia — an inherited condition that can raise testosterone from early life.
And reasons it runs low
- Aging — a gradual, natural decline in men typically begins in the mid-30s to 40s.
- Hypogonadism — reduced testicular or pituitary function that lowers testosterone production.
- Obesity — excess body fat is associated with lower testosterone levels in men.
- Chronic illness or significant stress — ongoing physical stress on the body can suppress testosterone production.
- Certain medicines — opioids and some other drugs can lower testosterone as a side effect.
Could a medicine be moving this number?
These medicines are known to shift Testosterone, Total. Seeing one you take does not mean it is the cause, and it is never a reason to stop on your own — it is a reason to ask whether your result needs reading in that light.
Never stop or change a prescribed medicine because of a lab result. Take the result and your medicine list to whoever prescribed it.
What should I eat?
Eat freely
- Vegetables, fruit, and whole grains daily — Weight loss can modestly raise testosterone when weight is high
- Dal, eggs, fish, or chicken — Steady protein supports overall hormone health
- Nuts and seeds in moderation — Provide healthy fats the body uses to make hormones
- Regular, balanced meals — Helps maintain a steady weight over time
Go easy on
- Alcohol — Regular heavy drinking is linked with lower testosterone
- Sugary drinks and refined snacks — Linked with weight gain, which can lower testosterone
Best avoided
- Crash diets or very low-calorie eating — Severe calorie restriction can suppress hormone production
- Testosterone boosters sold over the counter — Not regulated, and some carry real health risks
Can I exercise?
Stop and get help if
- Chest pain, pressure, or fainting
- Severe breathlessness during activity
- Severe fatigue that doesn't improve with rest
- Joint pain that worsens with activity
Activity, strength work, and better sleep help most when extra weight or poor sleep is part of the picture.
Your week
- 3 days: strength training with weights or body weight
- 2-3 days: brisk walking, cycling, or swimming
- Prioritize 7-8 hours of sleep each night
- 1-2 rest days for recovery
Start here: Two short strength sessions a week, using body weight
Skip for now
- Overtraining without enough rest or sleep
Check with your doctor first: Anyone with a pituitary, testicular, or adrenal condition, or taking hormone medicines, should have testosterone changes managed by a doctor rather than through diet or exercise alone.
General guidance for adults — not a personal diet plan. Your doctor or dietitian knows your full picture.

What to do next
Ask your doctor: “Was this sample drawn in the morning, when testosterone is typically at its highest?”
Ask your doctor: “Given my symptoms, does this level explain what I've been experiencing?”
Ask your doctor: “If this is low, should we also check LH and FSH to see where the problem originates?”

Questions people ask
Why does testosterone need to be tested in the morning?
Testosterone follows a daily rhythm and is typically highest in the early morning, gradually declining through the day. Testing later can show an artificially low result even in someone with normal production, so most guidelines recommend a fasting, early-morning sample, ideally repeated to confirm a borderline finding.
Is declining testosterone with age something to treat?
A gradual age-related decline is normal and doesn't automatically need treatment unless it's low enough, alongside relevant symptoms, to meet the criteria for a diagnosed deficiency. This is a decision made with a doctor weighing symptoms, level, and overall health rather than the number alone.
