Produced in the testicles, Testosterone is responsible for male characteristics such as a muscular build, a deep voice and facial hair. It usually reaches its highest level in a male early in adulthood, then drops, generally around 1% to 2% a year, after the age of 40. As men pass the 50 mark, they sometimes notice symptoms that they don’t want to deal with and avoid talking about:

  • Erectile dysfunction
  • Reduced sexual desire;
  • Depression;
  • Anxiety;
  • Lack of energy;
  • Weight gain;
  • Reduced muscle mass;
  • Reduced bone mass, which could lead to fractures;
  • Reduction in testicle size and the amount of semen produced;
  • An increase in body fat;
  • Mood swings, lack of focus, irritability and possibly depression.

Losing testosterone as you age is normal for men. Some choose testosterone replacement therapy restores their sex drive and helps them feel more alert, energetic and mentally sharp. This method doesn’t always work, however, because other issues can affect the level of the hormone in your body. These include obesity; alcoholism; stress; an injury or infection; medications you might be taking, especially those that are used to treat prostate cancer; or chemotherapy or radiation used to treat cancer.

And, just because you are dealing with erectile dysfunction doesn’t mean your testosterone levels are low. Other factors that can cause ED include:

  • High blood pressure;
  • Diabetes;
  • High cholesterol;
  • Thyroid issues;
  • Smoking.

Testosterone replacement therapy can be delivered in several different ways:

Skin patches

The patch, applied once a day, releases testosterone through the skin.


Shots are administered every seven to 14 days, usually immediately raising testosterone levels, which might slowly drop until the next shot is given.


The gel is rubbed into the skin, usually on the arms, shoulders or thighs, every day. You should always wash your hands well after applying the gel and cover the treated area with clothing to make sure others aren’t exposed to the testosterone.


Testosterone is absorbed into your bloodstream through tablets that are placed against your gum or the inside of your cheek twice a day.


These slowly release testosterone into your body after being implanted under your skin, usually near your hips or buttocks. They are replaced every three to six months.

There are natural ways to increase testosterone, and, though they might not raise testosterone levels to where they should be, they often help. These include losing weight and getting more exercise and eating food such as beef, fortified cereals, eggs, tuna, milk, beans and shellfish.

It’s important to remember that you might not have any of the symptoms of low testosterone. In fact, you might find out that your testosterone levels are low from the tests done on your blood during your annual physical.

Are you concerned about decreased sexual desire? Do you feel fatigued much of the time? Are you moody and irritable? All these issues could be related to low testosterone.
