Could you have low testosterone?: MedlinePlus Medical Encyclopedia

Testosterone, aging, and the mind

Beginning around age 40, men’s testosterone levels start to gradually drop by about 1 to 2% each year. Reduced testosterone levels are quite common, with over a third of men over age 45 having levels below what is considered normal for their age. Men may notice symptoms of fatigue, depression or loss of facial and body hair. Beyond the decrease in muscle mass, lower levels of testosterone can also cause brittle bones, which increases the risk of fractures.

Low T can cause physical symptoms and, in some cases, emotional/psychological concerns — mainly when the condition affects sexual performance. Some things that cause low testosterone can also cause a low sperm count. If your sperm count is low, your doctor might order this test.

In males, the testosterone test can help find the reason for sexual problems, like reduced sex drive or erectile dysfunction. If you’re having a hard time getting your partner pregnant, the test can tell if your blood testosterone level is low. A low testosterone level can also mean a problem with the hypothalamus or pituitary gland, which controls how much testosterone your body makes. Testosterone travels in the blood in one of two forms, either bound to one of two proteins or free and unbound. The hormone binds tightly to sex hormone–binding globulin but only weakly to the second protein, albumin. Only the free and albumin-bound forms of testosterone are biologically active; together, they are known as bioavailable testosterone.

You will generally receive results showing your testosterone levels within several days. Your results may be uploaded to an online health portal for viewing or sent to you in the mail.

If you read the list of ingredients on the bottle, they are mostly the same as what you find in an inexpensive multivitamin at the store. These products cost much more than the average multivitamin, and they give you the impression that they are raising your testosterone levels, but they are not actually doing so. Low testosterone is a condition in which the testicles fail to produce the male sex hormone testosterone.

However, what is considered clinically low levels of testosterone varies across guidelines, typically from 230–340 ng/dL. Your lab report should show the range that your lab uses for each test. Your doctor will also look at your results based on your age, health, and other factors. A value that isn’t in the normal range may still be normal for you. Treatment for high testosterone depends on the cause, but generally, it is a combination of lifestyle changes and medications.

Finally, increasing levels of testosterone through a negative feedback loop act on the hypothalamus and pituitary to inhibit the release of GnRH and FSH/LH, respectively. Conditions that affect how your hypothalamus and/or pituitary gland cause secondary hypogonadism. This is known as hypogonadotropic hypogonadism because there are low levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Those low levels cause decreased testosterone and sperm production. Low testosterone (male hypogonadism) is a condition in which your testicles don’t produce enough testosterone. It has several possible causes, including conditions or injuries affecting your testicles, pituitary gland or hypothalamus. The designation of “healthy range” for testosterone levels depends on age and laboratory assay.

Product labels for all testosterone formulations explicitly state that their use is contraindicated in men with a history of prostate cancer, which results from Huggins’ precept that testosterone therapy feeds prostate cancer cell proliferation. However, the literature at this time fails to define the LH level below which such adjunctive testing is warranted. In the event that a patient may have hypogonadotropic hypogonadism, adjunctive tests should be ordered. If you have abnormal testosterone levels, you should talk to your healthcare provider about the best treatment options for you.

Testosterone is a hormone that your gonads (sex organs) mainly produce. More specifically, both testicles and ovaries produce testosterone. Low testosterone — also known as hypogonadism or low T — can affect your overall health. But some doctors say it’s just a normal, harmless part of aging.
