Testosterone Levels in 50+ Year Old Men: What's Normal?

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.

Significance

• 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.

Averages

• 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.

Effects

• 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.

Treatments

• 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.

Warning

• 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.
