What are normal or average testosterone levels in men? In general, the normal range in males is about 270-1070 ng/dL with an average level of 679 ng/dL.
Age-specific middle tertile levels were 409-558 ng/dL for men 20-24 years old, 413-575 ng/dL for 25-29 years old, 359-498 ng/dL for 30-34 years old, 352-478 ng/dL for 35-39 years old, and 350-473 ng/dL for 40-44 years old.
An adult male's testosterone level should be between 270 and 1000. Testosterone levels peak at about the age of 20 years, and then the testosterone slowly declines with age.
Male: 300 to 1,000 nanograms per deciliter (ng/dL) or 10 to 35 nanomoles per liter (nmol/L) Female: 15 to 70 ng/dL or 0.5 to 2.4 nmol/L.
Just like it can be too low, your testosterone can also be too high, and that's equally problematic. When your testosterone levels are getting into the 1,000 up to the 1,500 ng/dL range—and staying up there—that's too high, says McDevitt.
Age-specific middle tertile levels were 409-558 ng/dL (20-24 years old), 413-575 ng/dL (25-29 years old), 359-498 ng/dL (30-34 years old), 352-478 ng/dL (35-39 years old), and 350-473 ng/dL (40-44 years old).
Most doctors agree that a “normal” reading falls anywhere between 300 to 1,000 nanograms per deciliter (ng/dL). About 40% of men over age 45 will have levels that come in below that range.
According to recent guidelines from the American Urological Association (AUA), a testosterone level of at least 300 nanograms per deciliter (ng/dL) is normal for a man. A man with a testosterone level below 300 ng/dL should be diagnosed with low testosterone.
Causes of Low Testosterone in Younger Men
For younger men, a drop in testosterone levels can be caused by some illnesses, including type 2 diabetes, chronic liver or kidney disease, COPD or other lung disease, or pituitary gland problems, according to Dr. Samadi.
“Exercise will boost testosterone, though certain types of exercise increase testosterone more than others,” says Richard Jadick, D.O., a Piedmont urologist. Exercise can raise testosterone because it promotes: Muscle building. The more muscle you have, the higher your testosterone levels.
In healthy young males the administration of suprahysiological testosterone doses (200-300 mg/wk) is anabolic to muscle mass, strength, and power.
What is a low testosterone level? The American Urology Association (AUA) considers low blood testosterone to be less than 300 nanograms per deciliter (ng/dL) for adults.
While normal is defined as total testosterone of 300–1000 ng/dL, patients in the 300–350 ng/dL range are viewed as borderline low, Dr. Eleswarapu says.
Bananas can boost testosterone as well as improve energy levels. Other beneficial fruits include watermelon and grapes. Citrus fruits can help testosterone production and reduce the hormones that make testosterone production less effective.
Acquired circumstances that can lead to secondary hypogonadism include: Normal aging: Aging affects production and response to hormones. Obesity: High body fat can affect hormone production and response. Medications: Opioid pain meds and steroids can affect function of the pituitary gland and hypothalamus.
Underactive testes, injury, illness, certain medical treatments, alcoholism, and obesity can all cause low testosterone. Low testosterone can also be caused by an underactive thyroid gland.
Healthy testosterone levels on mass spectrometry are 10.4-30.1 nmol/L in men 21 to 35 years with healthy reproductive function, and 7.4-28 nmol/L in unselected young men, the guidelines say. Very healthy men aged 70 to 89 have a healthy range of 6.4-25.6 nmol/L.
We show that total testosterone peaks [mean (2.5–97.5 percentile)] at 15.4 (7.2–31.1) nmol/L at an average age of 19 years, and falls in the average case [mean (2.5–97.5 percentile)] to 13.0 (6.6–25.3) nmol/L by age 40 years, but we find no evidence for a further fall in mean total testosterone with increasing age ...
Abnormally high testosterone levels are also known as hypergonadism. If you are male, your doctor may consider your testosterone levels too high if: Total testosterone level is above 950 ng/dL. Free testosterone level is above 30 ng/dL.
