It’s amazing how science can change the world. Back in the old days, men had certain expectations. We just knew that in our teens, 20’s, and 30’s, we’d have plenty of energy and virility. In our 40’s, that would start to level off, and in our 50’s and beyond, we would go into a gradual but irreversible decline. A bummer, but that’s just the way it was.

But as we mentioned, science changed the world. With developments in testosterone replacement therapy, more men than ever are able to experience a rejuvenation, and to recapture some of the energy from back in the day. But what is testosterone, and how and why does it affect so many aspects of your life?

Why Testosterone Matters

Testosterone is a hormone that appears in the bodies of both men and women, but it is found within men’s bodies at higher levels. Mostly produced in the testicles, this hormone is responsible for hair growth, sperm production, the building of muscle mass, and boosting bone density. Testosterone levels are usually at their peak when men are in their 20’s, and those levels often begin to drop once men reach their 40’s. However, bear in mind that testosterone levels aren’t equal for all men. Some men experience  a drop in their levels earlier in life, while others do not.

How Do I Know My Testosterone is Low?

Not all men will need to take part in testosterone replacement therapy. But how do you know if you’re a potential candidate? Some of the warning signs of low levels of testosterone are:

  • A reduced or lack of interest in sexual activity
  • Infertility
  • Erectile dysfunction
  • Sleep disturbances such as insomnia
  • Low levels of energy throughout the day
  • Emotional changes like anxiety, sadness, or depression
  • Cognitive issues such as difficulty concentrating and poor memory
  • Noticeable hair loss
  • Decrease in muscle mass
  • Gynecomastia, a condition in which men’s breasts become swollen

Low testosterone levels aren’t just an issue because of these symptoms. Men with reduced levels are at greater risk of dying from heart disease and cancer. That’s the bad news, but there is good news.

If you’re experiencing some or many of these symptoms, you may be a good candidate for testosterone replacement therapy. Through therapy, your testosterone levels will be gradually increased. However, before you decide to take part, it’s very important to make an appointment to see your doctor first and get your hormone levels checked. Your levels can be low, or your hormones can be imbalanced for a number of reasons, some of which are temporary. It’s true that the older you are, the more likely that your testosterone has begun to go down. All it takes is a simple and straightforward blood test.

Should you decide to go forwards with HRT, it tends to be most effective when your hormones are at their peak. Ideally, men in their 20’s will see the greatest effects. Having said that, older men have had tremendous success as well. It’s important to realize that treatments take time, and changes within your body are gradual.

Low testosterone is an issue worth taking seriously, for men of all ages. While we don’t live forever, there’s time to make changes.
