Symptoms of Low Testosterone in Men

Reduced Sex Drive

Forth logo

A significant decrease in libido is commonly caused by a sudden drop in testosterone levels, affecting your desire for sexual activity.

Erectile Dysfunction

Forth logo

If you're having trouble getting or maintaining an erection, it could be because low testosterone levels aren't providing the necessary signals for this vital function.

Fatigue

Forth logo

Feeling tired all the time, even after a good night's sleep, is a frequent sign that testosterone levels are impacting your energy and vitality.

Loss of Muscle Mass

Forth logo

Experiencing a noticeable drop in muscle mass and strength, despite maintaining a workout routine, suggests low testosterone is hindering muscle development.

Increased Body Fat

Forth logo

If you're struggling with unexplained weight gain, particularly around the abdomen, it may be due to low testosterone disrupting your body's metabolism and fat distribution.

Mood Changes

Forth logo

Feelings of depression, irritability, or difficulty concentrating are often rooted in low testosterone, as the hormone plays a key role in emotional and cognitive function.

Hair Loss

Forth logo

A decrease in facial or body hair growth beyond normal aging may be directly linked to a decline in the hormone responsible for hair production.

Decreased Bone Density

Forth logo

An increased risk of bone fractures is a serious concern, as low testosterone weakens bones by hindering the maintenance of bone mass.

Sleep

Forth logo

If you are struggling with insomnia, restlessness, or poor quality sleep, the imbalance in your testosterone levels may be to blame.

Frequently asked questions

This is what our customers ask us about the most. For more information, try our help centre.

What is testosterone?

Testosterone is a key hormone that plays a vital role in muscle mass, energy levels, mood, and overall well-being. While it’s often associated with men’s health, it’s also essential for women, contributing to bone strength, libido, and hormone balance.

Who is this test for?

This test is ideal for anyone who wants to check their testosterone levels, whether due to symptoms like low energy, reduced libido, mood changes, or concerns about hormonal health. It’s suitable for men and women looking to understand their hormone balance and take control of their long-term health.

What does this test check?

Our testosterone test measures your total testosterone levels to assess whether they fall within a healthy range. Abnormal levels can impact energy, muscle mass, mood, and overall well-being, making it an important marker for health monitoring.

Can I use this test when using TRT?

Yes. If you’re on testosterone replacement therapy (TRT), this test can provide insight into your testosterone levels.

Is this test suitable for women?

Yes. While testosterone is often discussed in relation to men’s health, it’s also an important hormone for women. Low testosterone in women can contribute to fatigue, low libido, and changes in muscle strength.

What causes testosterone levels to change?

Testosterone levels fluctuate due to age, lifestyle, stress, diet, sleep, and underlying health conditions. In men, levels naturally decline with age, while in women, they can be affected by menopause, PCOS, and other hormonal imbalances.

Can I increase my testosterone levels naturally?

Yes. Regular exercise, strength training, a nutrient-rich diet, quality sleep, and stress management can all help support healthy testosterone levels. In some cases, medical intervention may be necessary if levels are significantly low. This testosterone test gives you the knowledge to make tailored lifestyle changes or seek medical help to improve your testosterone levels.
