Testosterone Levels

Testing Testosterone Levels

Testosterone levels can be measured by a blood test usually done in the morning when testosterone levels are highest. Before the test, your doctor may ask you to stop taking any prescription medications that may affect your testosterone levels. Do not forget to tell your doctor if you are using any medications like androgens, anticonvulsants or similar.

Testosterone home testing kits are widely available. They use your blood or saliva to test your hormone levels. After taking the test, you’ll send your sample to a laboratory for testing.

What is hypogonadism?

Hypogonadism is reduced functional activity of the gonads (the testes or the ovaries) that may result in decresed production of sex hormones. There are two types of hypogonadism: Primary and Secondary;

Primary hypogonadism is that there are not enough sex hormones in the body due to malfunctioning of the testicles. Basically they are receiving the message from the brain but not functioning properly

Secondary (central) hypogonadism is a condition where the problem comes from the brain. The hypothalamus hormone and pituitary gland are located in the brain. They help regulate the production of sex hormones.

What are the benefits of TRT (Testosterone Replacement Theraphy)?

Besides treating the symptoms, Testosterone Replacement Theraphy may help you with cardiovascular health. Testosterone may aid in red blood cell production necessary for physical exertion and performance as well as aid in maintaining a strong healthy heart. A study [3] is published by US Department of Veterans Affairs that founds men with testosterone levels returned to a normal range were 36% less likely to have a stroke and 24% less likely to have a heart attack. Optimum Testosterone Levels can decrease fat while increasing muscle size and strength.

Also some scientists believes there may be a link between testosterone levels and chance of survival in male over 65 [4]
