Five Symptoms of Testosterone Deficiency

By The Vault Team

Testosterone is the primary male sex hormone, and it’s responsible for regulating many of the key processes in the male body. It directly affects your energy levels, libido, muscle production, and more. As Matt Wassmuth, one of Vault Medical Services of New York’s registered nurses, puts it: “If you're low on testosterone, you're going to lose a lot of what's good about being a man.”

Starting at age 30, the average man’s testosterone levels begin to drop by 1 to 1.5% a year. That might sound small, but in just a few years, it adds up. By 40, an estimated 40% of men suffer from low testosterone. By 50, the average man may have lost more than 30% of his testosterone. It’s not just aging that causes testosterone levels to drop. A variety of medical conditions that can cause testosterone levels to decrease, such as autoimmune diseases and inflammatory diseases such as tuberculosis.

Clinical studies have proven relationships between low testosterone and ED, decreased muscle mass, loss of bone mass, fatigue, decreased intimacy desires, difficulty concentrating, and reduced hair growth. And as more research is done about the effects of low testosterone, the symptom list keeps growing.

Those symptoms sound scary. But think of it this way: with the support of Vault Health, unrivaled access to your clinicians, and customized testosterone treatment plans, you can expect to feel increased sexual performance, increased muscle mass, increased bone density, stronger focus, and improved hair growth.

In short: we’ll get you back up to speed in no time.

You are probably asking yourself a simple question: “How do I know if I have a testosterone deficiency?” Testosterone’s role in your health is so varied and vast that, paradoxically, it can be hard to immediately know when you’re suffering from a deficiency. After all, there are a lot of reasons you could feel low energy or have trouble concentrating. Other medical conditions, along with lifestyle decisions like sleep, nutrition, and stress, make it difficult to pinpoint a testosterone deficiency on your own.

To start, learn more about the common symptoms of low testosterone below. These symptoms are based on the latest findings of the American Urology Association, published in “Evaluation and Management of Testosterone Deficiency: AUA Guideline,” and recommendations from expert urologists partnering with Vault Health.

1. Decreased Intimacy Desires

Related Symptoms:

● ED

The Science: One of the most common symptoms of low testosterone is ED and decreased intimacy desires. But there’s plenty of reason to remain optimistic. With testosterone treatments, clinical studies show improvements rectifying issues associated with intimacy desires and performance.

2. Low Energy

Related Symptoms:

● Fatigue

● Lower Endurance

● Diminished Work Performance

● Diminished Physical Performance

● Afternoon fatigue

Questions to Ask Yourself:

  • Do you have more trouble waking up than I used to?

  • Do you need more coffee/rest to be as productive as I was a few years ago?

  • Do you have a drop-off of energy during the afternoon?

  • Do you need more sleep to feel the same amount of energy?

The Science: The American Urology Association lists fatigue as an important symptom in diagnosing low testosterone. Not everyone with low energy has low testosterone, but people with low testosterone often suffer from low energy.

Lifestyle factors play a huge role in your energy levels as well as your testosterone levels. When discussing with your clinician, be sure to keep track of how those factors, such as your diet, stress, and sleep, have changed recently, too. Even with testosterone treatments, your clinician may suggest lifestyle changes that can increase your testosterone and overall energy levels, too.

3. Cognitive Dysfunction

Related Symptoms:

● Depressive symptoms

● Cognitive dysfunction (“Brain Fog”)

● Reduced motivation

● Poor Concentration

● Irritability

Questions to Ask Yourself:

  • Have you had more trouble focusing?

  • Have you been unable to focus for longer periods or need to work in shorter stretches?

  • Have you felt symptoms of depression?

  • Do you feel less “clear headed” than you used to?

  • Do you experience mood swings?

  • Are you noticeably more irritable than you have been in past years?

The Science: The AUA lists these cognitive symptoms as symptoms that may suggest further testing for low testosterone. Unlike erectile dysfunction and fatigue, these symptoms alone may not warrant a test for a testosterone deficiency unless combined with other symptoms.

The cognitive effects of low testosterone are still being studied, but studies of patients undergoing testosterone treatment have shown early indications that those suffering from depression and decreased concentration have improved after undergoing treatment.

4. Bone Density Loss

The Science: It’s estimated that one-third of men over 50 with a testosterone deficiency have bone density loss. The AUA panel recommends that “men who present with low-trauma bone fractures (LTBF) have their testosterone measured.”

5. Obesity

Related Symptoms/Medical Conditions:

● Increased midsection fat

● Diabetes

● Reduced lean muscle

Questions To Ask Yourself:

  • Have you noticed a weight gain that doesn’t feel fully explained by a lifestyle change?

  • Have you gained more weight than normal despite a relatively unchanged diet and exercise regimen?

  • Have you noticed a relative change in the amount of fat around your midsection?

The Science: The AUA suggests that “men who are obese (BMI ≥30) or who have increased waist circumference (>40 inches) should have their testosterone levels checked.”

Obesity can be caused by many things, including diabetes, which can also lower your testosterone. But obese men are “almost five times more likely to have low testosterone than men who are not obese,” and men with diabetes are more likely to have low testosterone.

Studies indicate lean muscle production increases after testosterone treatment, and fat levels, especially around the midsection, decrease. These elements often affect each other to create drastic changes. For instance, as you increase the amount of your lean muscle production, your physical endurance improves, which may improve your mood.
