Low testosterone levels (low T) in men are often caused by low thyroid function. This condition is called hypothyroidism. It affects nearly half of all men over age 40.
Hypothyroidism is a common problem among older men. In fact, many doctors believe that hypothyroidism is the most common cause of low testosterone in men. However, there are also other causes of low T including poor diet, stress, obesity, and lack of exercise.
If you suspect that you may have low T, then you should talk with your doctor about testing. He will likely order blood tests to check your thyroid hormone levels and free thyroxine index (FTI). A low FTI indicates that you may have hypothyroidism.

Is Low Testosterone Common?
Low testosterone levels are very common among men over 40 years old. Testosterone levels naturally decrease after puberty, and then continue to drop until about age 50. This is called “andropause” or “male menopause.”
Testosterone is a hormone produced by the testes. It helps maintain muscle mass, bone density, sexual desire, and sperm production. Low testosterone levels can cause fatigue, depression, erectile dysfunction, decreased libido, and lack of energy.
There are several factors that contribute to low testosterone levels. These include aging, stress, diet, alcohol consumption, smoking, medications, and certain medical conditions such as diabetes and thyroid problems.
What Are the Symptoms of Low Testosterone?
There are several symptoms of low testosterone levels. These include decreased sex drive, erectile dysfunction, fatigue, depression, hair loss, and poor muscle tone. Low testosterone levels may also cause bone density issues.
Symptoms of low testosterone levels may occur gradually over time or suddenly. If you notice any of these symptoms, you should consult your doctor immediately.
Decreased Sex Drive
A decrease in sexual desire is one of the most common symptoms of low testosterone levels, especially in men. This symptom may be caused by stress, anxiety, or depression.
Erectile Dysfunction
Erectile dysfunction occurs when there is an inability to achieve or maintain an erection. There are two types of erectile dysfunction: organic and psychogenic. Organic erectile dysfunction is due to physical problems such as diabetes, prostate enlargement, and neurological disorders. Psychogenic erectile dysfunction is usually associated with psychological factors such as stress, anxiety, and depression.
Fatigue
Men with low testosterone levels often feel tired and fatigued. Fatigue may be accompanied by sleep disturbances, irritability, and mood swings.
Depression
Many men with low testosterone levels suffer from depression. Depression is a major problem in older men. It is estimated that up to 30% of men over 65 years old experience depression.
Hair Loss
Hair loss is another common symptom of low testosterone levels. Hair loss may be temporary or permanent. Temporary hair loss is often seen in younger men, whereas permanent hair loss is usually observed in older men.
Poor Muscle Tone
Muscle tone refers to the strength of muscles. Men with low testosterone levels tend to have weaker muscles than normal men. Weak muscles may lead to back pain and joint stiffness.
Bone Density Issues
Osteoporosis is a condition where bones become weak and brittle. Osteoporosis is very common among women after menopause, but it can affect men too. The risk of osteoporosis increases with age.
Causes of Low Testosterone
Aging
As we age, our bodies begin to produce less testosterone. The exact reasons for this are unclear. However, there are many theories.
One theory is that as we age, our bodies become less efficient at converting T into DHT. Another theory is that our bodies stop producing T altogether.
Medications
Many medications can cause low testosterone levels. Some examples include antiandrogens, antidepressants, antipsychotics, antiepileptics, beta blockers, corticosteroids, diuretics, and thyroid hormones.
Diabetes
Diabetes is a major cause of low testosterone levels. In fact, one study found that almost 40% of diabetic patients had low testosterone levels.
The exact mechanism behind why diabetes leads to low testosterone levels is unknown. However, researchers believe that insulin resistance may play a role.
Obesity
Obesity is another factor that can lead to low testosterone levels. One study found that obese men were twice as likely to have low testosterone levels than non-obese men.
This could be due to increased levels of estrogen in the blood. Estrogen can block the effects of testosterone.
Sleep Apnea
Sleep apnea is a disorder where people stop breathing during sleep. It affects approximately 2 million Americans.
People with sleep apnea tend to snore loudly and experience daytime drowsiness. They also tend to gain weight around their waistline.
Studies show that people with sleep apnea have lower testosterone levels. Researchers think that this may be due to the lack of oxygen that occurs during sleep.
Depression
Depression is another factor that can cause low testosterone levels in men. Studies have shown that depressed men have lower testosterone levels.
Researchers believe that this may be due in part to changes in the brain’s production of serotonin. Serotonin is a neurotransmitter that helps regulate mood.
Alcohol Consumption
Alcohol consumption can cause low testosterone levels as well. A study published in the Journal of Clinical Endocrinology & Metabolism showed that heavy drinkers had significantly lower testosterone levels compared to moderate drinkers.
Smoking
Smoking cigarettes can decrease testosterone levels. One study showed that smoking was associated with a 50% reduction in testosterone levels.
Stress
Stress can cause low testosterone levels by interfering with your body’s ability to make testosterone.
Treating Low Testosterone
The first step in treating low testosterone levels is to rule out other causes. For example, if you have been diagnosed with hypogonadism, your doctor will perform blood tests to check hormone levels. Your doctor may recommend further testing if necessary.
Once your doctor has ruled out other possible causes, he or she will prescribe medication to treat your symptoms. In some cases, testosterone replacement therapy (TRT) may be recommended. TRT involves injecting synthetic testosterone into the bloodstream.
Injections of testosterone are typically given once per week. However, your doctor may adjust this dosage based on your individual needs.
Other treatment options include lifestyle changes and counseling. Lifestyle changes include eating healthy foods, exercising regularly, and avoiding alcohol. Counseling helps you learn coping strategies for dealing with stress and depression.
Testosterone is a male hormone produced primarily in the testicles. It plays an important role in maintaining health and well-being. Testosterone deficiency is known as hypogonadism. Hypogonadism affects both males and females.
Hypogonadism is defined as a disorder characterized by inadequate production of testosterone. It is also referred to as hypoandrogenism.
In conclusion, low testosterone levels can cause a variety of symptoms in men, including decreased energy, lower libido, erectile dysfunction, depression, fatigue, and poor sleep quality. Fortunately, there are several treatment options available to help restore normal hormone levels.
The first step toward restoring your hormones is to determine whether or not you have low testosterone. This can be done through a simple blood test, which will tell you whether or not your testosterone levels are within the normal range. If they aren’t, you’ll want to consult with a doctor who specializes in endocrinology to discuss further testing and possible treatments.
