Testosterone is the hormone responsible for secondary male characteristics. These include deepening of the voice, libido and body hair. As men age, testosterone levels drop.
Around 40, testosterone levels in men start to drop. Some men will notice it and seek medical help, while others will see it as a normal part of the aging process.
A man between 45 and 54 has a testosterone level of 606 nanograms per deciliter. This is a slight difference from age 35 when the average level is 668 ng/dl.
Some of the effects of low testosterone are a decreased sex drive, loss of muscle mass and mood swings. These can decrease the quality of life and lead to depression and lack of energy.
Options for treatment of low testosterone include injections, oral medication, pellets and gel. Injections are usually self-administered in the quadriceps or buttocks. Orals are taken by mouth, pellets are injected under the skin, and gel is massaged into the skin.
It is important to discuss treatment options with your doctor. Testosterone levels can be low regardless of age. It is a good idea to bring a list of questions about testosterone therapy if you are planning to discuss it with your doctor.
