12 Signs You Might Have Low Testosterone (And What You Can Do About It)

Ever feel like you're running on empty lately? Like your energy's zapped, your mood's off, or your sex drive just isn’t what it used to be? You're not alone, and it could be a sign of low testosterone, or what doctors call “Low T.”

Wait… What Is Testosterone Anyway?

Testosterone is a hormone that both men and women have, but it’s especially important for men. It’s responsible for things like muscle growth, sex drive, bone strength, red blood cell production, and even your mood. In men, it’s mainly made in the testicles.

Testosterone levels naturally start to dip as you get older. But for some guys, it drops more than it should. That’s when symptoms start to show up, often without warning.

So What Are the Signs of Low Testosterone?

Here are 12 common signs that your testosterone might be on the low side:

1. Low Sex Drive

One of the biggest red flags. If you’ve lost interest in sex and it’s not just a “stressful week,” it could be a hormone issue. Your partner might notice before you do.

2. Trouble Getting or Keeping an Erection

Testosterone helps kick off the process that leads to an erection. If things aren’t working like they used to, Low T might be part of the picture. Although other factors like stress, blood pressure, and diabetes can also play a role.

3. Constant Fatigue

Feeling tired all the time, even after a full night’s sleep? Low testosterone can zap your energy and make you feel worn out for no obvious reason.

4. Weight Gain (Especially Around the Belly)

Gaining weight, especially in your midsection? A drop in testosterone can lead to more body fat and even man boobs (gynecomastia) in some cases. Not fun.

5. Loss of Muscle Mass

Testosterone helps build and maintain muscle. If you’re losing strength or muscle without changing your routine, your hormone levels could be the culprit.

6. Smaller Volume When You Ejaculate

Less fluid during sex? Testosterone plays a role in semen production, so lower levels can affect this too.

7. Weaker Bones

Most people don’t realize this, but testosterone helps keep your bones strong. Low levels can lead to weaker bones and increase your risk for fractures down the road.

8. Hair Loss

While hair loss can be genetic, low testosterone can speed up the process or lead to thinning of body and facial hair.

9. Mood Swings & Irritability

Feeling more emotional, down, or just "off"? Hormones impact your mental health too. Low T can lead to irritability, sadness, or even depression.

10. Trouble Focusing or Remembering Things

Some guys notice their brain feels foggy. Memory, concentration, and focus can take a hit with low testosterone.

11. Shrinking Testicles

It’s not something most guys like to talk about—but low testosterone can cause a noticeable reduction in testicle size.

12. Low Red Blood Cell Counts

Testosterone helps your body make red blood cells. If your levels are low, you could be more prone to anemia, which adds to the fatigue and weakness.

What Causes Testosterone to Drop?

Aside from aging, there are other things that can mess with testosterone levels:

• Chronic stress

• Poor sleep

• Lack of exercise

• Unhealthy diet

• Certain medications

• Environmental toxins (yes, even some plastics and chemicals)

Some studies have even looked at the effects of things like electromagnetic radiation and excess estrogen-like substances in our environment.

How Do You Find Out If You Have Low T?

The only real way to know is through a blood test, specifically a serum testosterone test. Normal levels are generally between 300–1000 ng/dL. If you’re below that, your doctor might recommend lifestyle changes or, in some cases, testosterone replacement therapy (TRT).

But here’s the deal: The goal isn’t to push your levels into the super-high zone. It’s about getting them back into a healthy range so you feel like yourself again—energized, motivated, and clear-headed.

Should You Get Checked?

If you’re reading this and thinking, “This sounds like me,” it might be worth getting your levels checked. Whether you’re in your 30s or your 70s, low testosterone can impact your quality of life. The good news? It’s manageable.

Final Thoughts

Low testosterone isn’t something to be embarrassed about. It happens to a lot of men, and recognizing the signs is the first step. Whether it’s fatigue, weight gain, or just not feeling like yourself, don’t ignore the signals your body is giving you.
