Are you experiencing fatigue, low libido, weight gain, or mood changes? These could be signs of low testosterone. Low testosterone (Low T) affects millions of men, particularly as they age, but many don’t recognize the symptoms or know that effective treatment is available. At Infinite Vitality in Glen Carbon, serving Edwardsville, Troy, and Collinsville, we help men restore their vitality through comprehensive hormone replacement therapy. This guide covers the 10 most common low testosterone symptoms and what you can do about them.
What Is Low Testosterone?
Testosterone is the primary male sex hormone responsible for:
• Sexual function and libido
• Muscle mass and strength
• Bone density
• Red blood cell production
• Mood and mental clarity
• Energy levels
• Fat distribution
**Normal testosterone levels:**
• Age 19-39: 300-1,000 ng/dL
• Age 40-59: 300-890 ng/dL
• Age 60+: 300-720 ng/dL
Low testosterone (hypogonadism) occurs when levels fall below 300 ng/dL. However, symptoms can occur even at “normal” levels if your testosterone has declined significantly from your personal baseline.
How common is Low T?
• Affects approximately 40% of men over age 45
• Prevalence increases with age
• Can also affect younger men due to various factors
• Often goes undiagnosed because symptoms develop gradually
10 Most Common Low Testosterone Symptoms
1. Decreased Libido (Sex Drive)
One of the most noticeable signs of low testosterone is a significant decrease in sexual desire. While it’s normal for libido to decline somewhat with age, a dramatic drop could indicate Low T.
Signs to watch for:
• Lack of interest in sex
• Rarely thinking about sex
• Loss of spontaneous erections (morning erections)
• Reduced response to sexual stimulation
2. Erectile Dysfunction
Low testosterone can contribute to difficulty achieving or maintaining erections. While Low T isn’t the only cause of ED, it’s an important factor to consider.
Important note: Testosterone helps trigger nitric oxide production, which is essential for erections. Low levels can make achieving erections difficult.
3. Chronic Fatigue and Low Energy
Do you feel exhausted even after a full night’s sleep? Persistent, unexplained fatigue is a hallmark symptom of low testosterone.
You might experience:
• Extreme tiredness despite adequate rest
• Lack of motivation or energy
• Difficulty completing daily activities
• Afternoon energy crashes
• General feeling of sluggishness
4. Loss of Muscle Mass
Testosterone plays a crucial role in building and maintaining muscle. Low T can lead to:
• Decreased muscle mass (even if you exercise)
• Reduced strength
• Difficulty building muscle despite workouts
• Muscle weakness
• Longer recovery time after exercise
5. Increased Body Fat
Many men with low testosterone experience:
• Weight gain, especially around the midsection
• Development of breast tissue (gynecomastia)
• Difficulty losing weight despite diet and exercise
• Changes in body composition (less muscle, more fat)
6. Mood Changes and Depression
Testosterone affects mood and mental well-being. Low levels can cause:
• Depression or persistent sadness
• Irritability and mood swings
• Anxiety
• Reduced sense of well-being
• Lack of motivation
• Decreased self-confidence
7. Cognitive Difficulties
Many men report “brain fog” with Low T:
• Difficulty concentrating
• Memory problems
• Reduced mental clarity
• Slower thinking
• Trouble focusing on tasks
8. Sleep Disturbances
Low testosterone can disrupt sleep patterns:
• Insomnia or difficulty falling asleep
• Waking frequently during the night
• Poor sleep quality
• Sleep apnea (can be both cause and effect of Low T)
9. Decreased Bone Density
Testosterone helps maintain bone strength. Low T can lead to:
• Osteoporosis or osteopenia
• Increased risk of fractures
• Weaker bones
• Joint pain
10. Hair Loss
While male pattern baldness is genetic, testosterone plays a role in hair production:
• Thinning body hair
• Reduced facial hair growth
• Slower hair growth
Less Common Symptoms:
• Hot flashes or sweating
• Reduced testicle size
• Decreased semen volume
• Breast tenderness
• Anemia (low red blood cell count)
What Causes Low Testosterone?
Age-Related Decline:
• Natural testosterone production decreases about 1% per year after age 30
• By age 70, levels may be 50% lower than in your 20s
• This gradual decline is called “andropause” or “male menopause”
Medical Conditions:
• Type 2 diabetes
• Obesity
• Chronic kidney disease
• Liver disease
• HIV/AIDS
• Pituitary gland disorders
• Testicular injury or infection
• Chemotherapy or radiation
• Certain medications (opioids, steroids)
Lifestyle Factors:
• Chronic stress
• Poor sleep
• Excessive alcohol consumption
• Lack of exercise
• Poor diet
• Drug use
Other Factors:
• Genetic conditions (Klinefelter syndrome)
• Hemochromatosis (excess iron)
• Inflammatory diseases
• Sleep apnea
How to Test for Low Testosterone
If you’re experiencing multiple symptoms, testing is essential.
Blood Test:
• Simple blood draw
• Measures total and free testosterone
• Best done in the morning (levels are highest)
• May require fasting
• Often covered by insurance with symptoms
At Infinite Vitality, our comprehensive evaluation includes:
• Complete medical history
• Physical examination
• Blood work (testosterone levels, other hormones, cholesterol, blood sugar)
• Discussion of symptoms and health goals
• Review of medications and medical conditions
What gets tested:
• Total testosterone
• Free testosterone (active form)
• SHBG (sex hormone binding globulin)
• LH and FSH (pituitary hormones)
• Estradiol (estrogen)
• PSA (prostate health)
• Complete blood count
• Liver and kidney function
When to test:
• If you have multiple Low T symptoms
• Before starting any treatment
• Regularly during treatment to monitor levels
• If symptoms return despite treatment
Treatment Options: Testosterone Replacement Therapy (TRT)
The good news: Low testosterone is highly treatable.
Testosterone Replacement Therapy Methods:
1. Injections (Most Common & Effective)
• Administered weekly or bi-weekly
• Testosterone cypionate or enanthate
• Most cost-effective option
• Provides stable levels
• Can self-administer at home
2. Topical Gels/Creams
• Applied daily to skin
• Absorbed through skin
• Convenient but can transfer to others
• More expensive than injections
3. Patches
• Applied to skin daily
• Less common nowadays
• Can cause skin irritation
4. Pellets
• Implanted under skin every 3-6 months
• Provides steady hormone release
• Requires minor procedure
• More expensive
5. Oral Medications

At Infinite Vitality, we typically recommend testosterone injections because they:

Is TRT Safe? Understanding the Risks and Benefits
Benefits of TRT:
- Increased energy and vitality
- Improved sexual function and libid
- Enhanced muscle mass and strengt
- Better mood and mental clarity Reduced body fat
- Stronger bones
- Improved cardiovascular health markers
- Better quality of life
Potential Risks (when properly monitored):
- Increased red blood cell count (managed with monitoring)
- Acne or oily skin
- Sleep apnea (can worsen existing condition)
- Breast enlargement (rare, manageable)
- Testicular shrinkage
- Reduced fertility (reversible)
Myths About TRT:
- “TRT causes prostate cancer”- No evidence supports this
- “TRT causes heart attacks” – Recent studies show no increased risk with proper dosing
- “TRT is dangerous” – When properly prescribed and monitored, TRT is safe
- “You’ll become dependent” – Your body has already stopped producing adequate testosterone
At Infinite Vitality , we monitor you closely with:
• Regular blood work (every 3-6 months)
• Symptom tracking
• Physical exams
• PSA monitoring (prostate health)
• Adjustments as needed
esting is recommended if you have symptoms, regardless of age. Most men over 40 should consider baseline testing.
TRT can reduce sperm production temporarily. If fertility is a concern, discuss alternative treatments like HCG or Clomid with your doctor.
Most men require ongoing treatment since Low T is often a chronic condition. However, you can discontinue if desired under medical supervision.
Stopping TRT will likely cause symptoms to return. Some men choose to stop, but most continue long-term for sustained benefits.
Many insurance plans cover TRT when medically necessary. We accept insurance, HSA/FSA, and offer affordable self-pay options.
