Low Testosterone Symptoms and How to Recognize Them Early
Dr. Calvin VanShare
Testosterone is more than just the hormone responsible for male physical characteristics, it plays a crucial role in a man’s overall health, from muscle and bone strength to mood, energy, and libido. Yet, many men experience a gradual decline in testosterone levels without even realizing it. Recognizing the early signs of low testosterone, also known as hypogonadism, can help prevent further health complications and improve your quality of life. In this guide, we’ll help you understand the early signs of testosterone deficiency, how it affects the body and mind, and what you can do to manage it naturally and effectively.

Understanding Low Testosterone (Hypogonadism)
Low testosterone, medically known as hypogonadism, refers to a condition in which the body does not produce enough of the hormone testosterone. This hormonal deficiency can occur at any age, but it becomes increasingly common in men over 40 as testosterone levels naturally decline with age.
There are two main types of hypogonadism:
- Primary hypogonadism: This type originates in the testes, where testosterone is primarily produced. In this case, the testes are unable to produce adequate amounts of testosterone, despite proper signaling from the brain. Causes may include genetic conditions (e.g., Klinefelter syndrome), testicular injury, or infections like mumps.
- Secondary hypogonadism: This occurs when the hypothalamus or pituitary gland — parts of the brain responsible for hormone regulation — fail to send proper signals to the testes. This can result from aging, obesity, chronic illnesses, or even stress-related factors.
In many cases, low testosterone is not caused by a single issue but rather a combination of age-related decline and lifestyle or health factors. For instance, chronic diseases such as type 2 diabetes, obesity, metabolic syndrome, and sleep apnea have been closely linked to reduced testosterone levels. Certain medications, such as opioids and corticosteroids, can also contribute to hormonal suppression.
Hypogonadism may be underdiagnosed because its symptoms often overlap with other conditions or are mistaken for natural aging. Men may dismiss early signs like fatigue, mood changes, or decreased libido as normal parts of getting older, without realizing there may be an underlying hormonal imbalance.
Common Physical Symptoms of Low Testosterone

The physical signs of low testosterone are often the first to appear. They may include:
- Decreased muscle mass and strength
- Increased body fat (especially around the abdomen)
- Reduced bone density, increasing the risk of fractures
- Persistent fatigue and low energy levels
- Hair loss, including facial and body hair
Over time, these physical changes can impact self-esteem and physical performance.
Emotional and Cognitive Effects

Testosterone doesn’t just affect the body; it influences the mind too. Some emotional and mental health-related symptoms include:
- Mood swings
- Irritability and anxiety
- Persistent feelings of sadness or depression
- Brain fog or difficulty concentrating
- Decreased motivation or drive
If you feel like “you’re not yourself lately,” low T might be a factor.
Sexual Dysfunction and Reproductive Impact

Testosterone is central to male sexual health. When levels drop, it can lead to:
- Reduced libido (sex drive)
- Difficulty achieving or maintaining erections
- Lower semen volume
- Decreased fertility
These issues can strain relationships and self-confidence if not addressed.
How to Test Your Testosterone Levels

If you suspect low testosterone, the most reliable way to confirm it is through a testosterone blood test.
- Timing matters: Testosterone is highest in the morning. A sample taken between 7–10 a.m. is most accurate.
- Total testosterone levels are usually measured first. If abnormal, your doctor may also check free testosterone, LH, and FSH levels to pinpoint the cause.
- Normal testosterone levels in men typically range from 300 to 1,000 ng/dL, depending on age.
You can get tested through your doctor or through licensed at-home test kits.
When to Seek Medical Advice
If you experience several of the symptoms listed above, especially those affecting your quality of life, speak to a healthcare provider. Left untreated, testosterone deficiency can lead to more serious health risks, including:
