Determining normal testosterone levels in men is typically based on age.
These average testosterone levels can very widely between adolescence and middle age and into the senior years.
Testosterone is a male hormone produced by the testes.
It’s also produced in very small amounts by women’s ovaries and is beneficial for a number of aspects of growth, development, and health.
Certain hormones decline as we age, and that goes for male testosterone and female estrogen, two hormones linked to sexual interest or libido, function, and fertility.

Testosterone levels in men vary widely not only based on age group, but by diet, exercise, lifestyle, and environment.
Average levels are meant as a guideline, and may differ a little or a lot even within age groups.
Rising levels are most prevalent during the teenage or pubescent years, and then level off as men enter early adulthood.
These levels, unless a medical condition interferes, remain relatively static until a man reaches his 30s or 40s.
They may decrease approximately 1% every year after he reaches the age of 30 or 40, but it’s nearly impossible to determine exactly when that decline is going to occur.
By then, production gradually begins to decrease, much as female ovaries decrease production of estrogen leading to menopause.
This drop in males starting in middle age is also known as male menopause.
A number of healthcare professionals and organizations such as the University of Rochester Medical Center and the Mayo Clinic have determined averages when it comes to testosterone levels considered within normal range.
The hormone is measured in nanograms per deciliter or ng/dL.
According to the University of Rochester Medical Center, normal ranges for a healthy adult man is 280 to 1,000 ng per deciliter. Testosterone levels for women average 15 to 70 ng per deciliter.
Men may experience a variety of signs and symptoms that testosterone levels are declining. A few of those include:
A simple blood test performed by your doctor and sent to a lab can determine total levels.
Testosterone levels in men can differ widely depending on numerous factors.
Such factors include not only age but the presence of any defect or deficiency of the pituitary or hypothalamus glands.
Just because you’re measured at the lower end doesn’t mean you’re a candidate for treatment, especially if any signs and symptoms you’re experiencing do not interfere with the overall quality of life.
If your testosterone levels are measured lower than normal based on age, the doctor will want to determine what is causing this decline if your age is not a contributing factor.
Some causes for decreased production of the hormone in men can include issues with the pituitary or hypothalamus gland.
The hypothalamus sends instructions to the pituitary gland to either increase or decrease production in the testes. The pituitary gland is responsible for the regulation of all hormones and gland functions in the body.
If testosterone is lower or higher than average, issues with fertility and libido may become more apparent.
If you have low T, a number of options are available to increase production.
Some of these are in the form of prescription drugs such as used in testosterone replacement therapy (TRT) treatment plans. Other options include prescription injections, gels, creams, and lotions.
Over-the-counter nutritional supplements known as boosters and enhancers can also be considered if you don’t want to take prescription drugs.
Such supplements don’t contain the hormone, but vitamins, minerals, and herbal ingredients that focus on providing support to the endocrine system and most specifically the pituitary gland.
If you’re concerned about whether your testosterone levels are normal, and you have begun to experience some signs and symptoms of low T, schedule a visit with your doctor.
A simple blood test can determine your average testosterone levels by performing the test several times and at different times of the day.
Be aware however, that TRT is not recommended for every man with low T, especially those whose decline in production is caused by normal aging processes.Function of TestosteroneTestosteroneTestosterone HormoneTestosterone DeficiencyTestosterone EnhancersTestosterone FoodsTestosterone for BodybuildingTestosterone for MenTestosterone Normal RangeTestosterone LevelsTestosterone Levels By AgeTestosterone ProductionTestosterone Replacement TherapyTestosterone SuppressionTestosterone TestTop Testosterone BoostersTestosterone and AnxietyTestosterone and Hair LossTestosterone and LibidoTestosterone DietFree Testosterone
