Average Testosterone Level Male: Testosterone is regarded to be the “male hormone” that’s created in males by the testes. Although women’s ovaries produce some testosterone, the hormone is produced in much higher concentrations in men and it is responsible for many of the secondary sex characteristics seen in men such as a deeper voice and hair on the chest, in addition to contributing to a healthy libido, building muscle mass, and maintaining energy levels.
Testosterone levels are evaluated by blood testing. Most clinicians believe that a “normal” value falls somewhere from 300 to 1,000 nanograms per deciliter (ng/dL). About 40 percent of males over age 45 will have levels that come in below that threshold. But a low reading by itself isn’t enough to raise anxiety.
In reality, it’ll likely have a lot to do with the time of day physicians test your blood. The optimal period for testing is between 7 and 10 a.m. “Varied hormones have different patterns of secretion,” explains Ronald Swerdloff, MD, head of endocrinology at Harbor UCLA Medical Center. “Normal testosterone ranges are predicated on morning samples, when the typical individual is at a higher level. Afternoon testing may offer a deceptive impression of low levels.”
Swerdloff says you should receive numerous tests — at least two over the span of a number of weeks or months. You’ll want to be sure you have a low T before you take any action.
Even if your testosterone levels are below the optimum range, you still may not have to worry. Doctors claim that a value between 200 and 300 ng/dL is somewhat of a gray region.
Levels that are only slightly low aren’t a reason for worry by themselves. But if you have additional symptoms, you’ll want to consult your doctor. “Everyone agrees that if you had a tremendously low amount, you’d benefit from therapy. But if it’s just slightly low, which is more frequent, you’d certainly want to have symptoms,” says Bradley Anawalt, MD, head of medicine at the University of Washington.
The difficulties linked with high testosterone levels are unusual and rare in middle-aged and older men who are not getting testosterone or other steroid medications. When the testosterone level falls out of balance, it generally becomes too low rather than excessively high.
The most frequent “out of balance” testosterone levels are found to be on the low side of normal; this arises because a male’s greatest testosterone level normally peaks at approximately age 20, and then it falls progressively with age. It has been claimed that a 1 percent decline in testosterone level every year is not uncommon for middle-aged (30 to 50 years old) and older individuals. While this decline may not be obvious in some men, others may suffer considerable alterations beginning in their middle-aged years or more typically around age 60 and beyond. This decline in testosterone levels is often dubbed hypogonadism, “male menopause” or andropause.
