15 Symptoms of Low Testosterone in Men: A Detailed Overview 

Low Testosterone

Are you feeling tired and low on energy? This might be a symptom of low testosterone levels. Low testosterone, also called ‘male hypogonadism’ is a condition in which the Leydig cells in the testicle don’t produce enough testosterone. 

There can be many different causes for low testosterone levels in men including injuries to the testicles, obesity, obstructive sleep apnea, and chronic medical conditions such as kidney failure. 

The common low t symptoms in men include reduced sex drive, hair loss, feeling low energy, and sometimes feeling depressed. 

In this blog, we will talk in detail about the 15 symptoms of low testosterone in men and how to treat them. 

15 Symptoms of Low Testosterone in Men

1. Low Sex Drive

Low testosterone levels directly affect the sex life of a man. Yes, people who get older may indeed experience a decrease in their sex drive but those with testosterone levels below normal levels can experience a significant decrease in their sex drive. Low testosterone can make it harder to feel interested in sex. 

2. Erectile Dysfunction

Secondly, a person with low testosterone levels may have erectile dysfunction. It is a medical condition in which the person doesn’t produce enough testosterone for sex with his partner. Low testosterone can make it difficult to get or keep an erection. It may also reduce sexual satisfaction and confidence.

Note: Low testosterone is one of the reasons for erectile dysfunction. It is not necessarily true that all erectile dysfunction occurs due to low testosterone levels. 

3. Losing Muscle Mass

Low testosterone levels can lead to a noticeable decrease in muscle mass. Testosterone plays a key role in muscle growth and strength. When levels drop, the body struggles to maintain muscle size and tone. This can make physical activities feel more difficult. Even with exercise, muscle growth may be slower or less effective. Over time, reduced muscle mass can lead to weakness and fatigue.

4. Loss of Body Hair

Low testosterone levels can cause a loss of body hair. Testosterone helps in hair growth on the face, chest, and other parts of the body. When levels drop, men may notice thinning or patchy hair loss. This can affect the beard, arms, legs, and even pubic hair. In some cases, the hair may not grow back. This change is usually gradual but can be a sign of hormonal imbalance.

5. Increased Body Fat

Low testosterone levels can lead to increased body fat. Testosterone helps regulate fat distribution in the body. When levels drop, men may gain weight more easily, especially around the belly. Some may also develop a condition called gynecomastia, which causes enlarged breast tissue. This happens due to an imbalance between testosterone and estrogen. Maintaining a healthy diet and exercise can help manage weight gain, but hormonal treatment may also be needed

6. Decreased Bone Mass

Low testosterone levels can lead to decreased bone mass. Testosterone plays a key role in keeping bones strong and dense. When levels drop, bones may become weaker and more fragile. This increases the risk of fractures and osteoporosis. Men with low testosterone may experience joint pain or a higher chance of bone injuries. Regular exercise and proper nutrition can help support bone health, but medical treatment may also be needed.

7. Mood Changes

Low testosterone levels can cause mood changes. Men with low testosterone may feel more irritable, anxious, or depressed. They may also experience a lack of motivation or energy. These mood swings can affect daily life and relationships. Sometimes, it can lead to feelings of sadness or frustration. Hormonal therapy or lifestyle changes can help improve mood and well-being.

8. Shrinking testicles

Low testosterone levels can cause the testicles to shrink. Testosterone is essential for maintaining testicle size and function. When levels drop, the testicles may become smaller and softer. This can also affect sperm production and fertility. Some men may notice reduced firmness or a change in shape. Treating low testosterone may help prevent further shrinking.

9. Enlarged prostate

Low testosterone levels can contribute to an enlarged prostate. The prostate gland may grow bigger due to hormonal imbalances. This can lead to urinary problems like frequent urination, weak urine flow, or difficulty emptying the bladder. Some men may also experience discomfort or pressure in the lower abdomen. If untreated, it can increase the risk of prostate-related conditions. Medical treatment or lifestyle changes can help manage symptoms.

10. Infertility

Low testosterone levels can lead to infertility. Testosterone is essential for sperm production. When levels drop, sperm count and quality may decrease. This can make it harder to conceive a child. Some men may also experience reduced semen volume. Treating low testosterone may help improve fertility in some cases.

11. Depression

Low testosterone levels can increase the risk of depression. It can cause feelings of sadness, hopelessness, or a lack of interest in daily activities. Men may also experience fatigue, low energy, and difficulty concentrating. These mood changes can affect relationships and work performance. If left untreated, depression can worsen over time. Therapy, lifestyle changes, and medical treatment can help improve mental well-being.

12. Moodiness and Irritability

Low testosterone levels can cause moodiness and irritability. Men may feel more easily frustrated or angry without a clear reason. Small issues might seem more upsetting than usual. They may also struggle with stress and anxiety. These mood swings can affect relationships and daily life. Hormonal treatment and lifestyle changes can help improve emotional balance.

13. Fatigue

Low testosterone levels can cause constant fatigue. Men may feel tired even after a full night’s sleep. They may struggle with low energy and motivation throughout the day. Simple tasks can feel exhausting and difficult to complete. This can affect work, exercise, and overall quality of life. Proper treatment can help restore energy levels and improve well-being.

14. Increased body fat

Low testosterone levels can lead to increased body fat. It affects how the body stores and burns fat. Men may notice more fat around the belly and chest. Some may develop gynecomastia, or enlarged breast tissue, due to hormonal imbalance. Weight gain can also lead to lower energy levels and reduced confidence. A healthy diet, exercise, and medical treatment can help manage body fat.

15. Hot flashes

Low testosterone levels can cause hot flashes. Men may suddenly feel intense warmth, especially on the face, neck, and chest. This can lead to sweating, chills, and discomfort. Hot flashes may occur during the day or disrupt sleep at night. They are caused by hormonal imbalances affecting the body’s temperature control. Treatment can help reduce or manage these symptoms.

How to treat low testosterone in men?

Low testosterone can be treated in different ways. Testosterone replacement therapy (TRT) is the most common option. It includes gels, patches, injections, or implants to restore hormone levels.
