What Is A Normal Testosterone Level For Your Age?

There is no utility in continuing testosterone therapy in men who achieve target testosterone levels without symptom improvement. An exception can be made if patients do not have symptoms but have documented BMD loss. In this clinical scenario, an argument can be made to continue testosterone therapy. Similarly, in the event patients have unexplained anemia that improves on testosterone therapy, continuation can be considered even in the absence of other symptom improvement. Specifically, the AUA does not recommend routine PSA testing in men years of age unless they are at higher risk (e.g., positive family history, African American race), at which point decisions regarding PSA testing should be individualized. In men years of age, biennial PSA testing should be considered.

If your testosterone levels are higher or lower than normal, you may have a condition that affects your testosterone production. If your levels are higher than normal, you may have a tumor on the testes or ovaries. The testosterone level in boys and men changes throughout life. They measure testosterone using a blood test, with results provided in nanograms per deciliter (ng/dL). It’s a simple blood test that’s usually done early in the morning, when your testosterone levels are highest. You will have a tube of blood taken from a vein in your arm or finger.

Testosterone is a natural hormone produced primarily in the testicles, and it helps men maintain everything from bone density and body hair to sex drive and sperm production. However, you don’t have to hit a certain number or level despite what the constant flow of ads may tell you. A decrease in leptin, supposedly an appetite suppressant, was due mostly to a drop in fat mass, which produces leptin. But that should not be construed as a negative effect of T therapy, according to Villareal. Villareal and her team found that men, regardless of their baseline testosterone level, benefited to some extent from T therapy. For instance, men with levels less than 264 ng/dL showed a greater increase at 18 months in total fat-free mass, which is mostly lean muscle mass, compared with those higher than 264 ng/dL. The basis for Villareal’s study was the finding from another study that bone mineral density (BMD) response to testosterone therapy in men with low T levels is influenced by baseline T levels.

In contrast to topical agents where a percentage of men have difficulty achieving therapeutic levels within standard dosing ranges, injectable testosterone preparations are able to achieve therapeutic levels in almost any clinical scenario. However, compared to other agents, short-acting injections can result in longer times in the supra-therapeutic and sub-therapeutic ranges, which may impact overall efficacy and rates of adverse events. This may be overcome by altering injection dose and frequency. The pharmacokinetics of short-acting testosterone therapy depends on the dose, interval, and method of delivery (SQ versus IM).

In other cases, the problem originates in the pituitary gland of the brain; causes include tumors (almost all benign), head trauma, brain surgery, various medications, some hereditary disorders, severe malnutrition, and chronic illnesses. When men (and, for that matter, women) think about the powers of testosterone, they are not likely to consider mental processes. Indeed, the male hormone has much more obvious roles in a man’s body. Still, new research suggests that testosterone may have a surprising role in masculine mentality. This treatment is called testosterone replacement therapy, or TRT.

Testosterone replacement therapy, in the form of injections, pellets, patches or gels, can improve the signs and symptoms of low testosterone in these men. Testosterone levels generally peak during adolescence and early adulthood. As you age, your testosterone level gradually declines — typically about 1% a year after age 30 or 40. For older men, it’s important to determine if a low testosterone level is due to normal aging or if it is due to a disease (hypogonadism). Throughout the reproductive life of males, the hypothalamus releases GnRH in pulses every 1 to 3 hours. Despite this pulsatile release, however, average dose of trt plasma levels of FSH and LH remain fairly constant from the start of puberty, where levels spike, to the third decade of life, where levels peak and slowly begin to decline. Before puberty, testosterone levels are low, reflecting the low secretion of GnRH and gonadotropins.

Some specific testosterone levels for different ages are listed below. However, it’s crucial to see that they are ranges and to know your goal shouldn’t necessarily be to reach or exceed the high end of the spectrum. This article addresses common questions about this crucial hormone.
