Frequently Asked Questions
What are the symptoms of low testosterone?
Common symptoms include low energy, reduced muscle mass, weight gain, mood swings, brain fog, hair loss, and decreased sex drive. Some men also experience sleep problems or increased body fat.
What causes low testosterone?
Low testosterone (hypogonadism) can be caused by natural aging, stress, obesity, medical conditions, or certain medications. Levels typically peak in your early 20s and decline gradually after age 30.
When does testosterone start to decline?
Testosterone usually peaks between ages 19–25. After about age 30, levels decline by 1–2% per year on average. That’s why many men notice changes in energy, strength, and mood as they get older.
How do I know if I have low testosterone?
The only way to confirm low testosterone is through a blood or saliva test. Symptoms alone can be misleading since they overlap with other conditions.
If you think you may have low testosterone, taking a test may be a good next step for you. Visit your top tests page to learn more.
Can lifestyle changes improve testosterone naturally?
Yes. Regular exercise, maintaining a healthy weight, managing stress, and getting quality sleep can all support testosterone production. However, some men may still need medical treatment if levels are significantly low.
What are treatment options for low testosterone?
Treatment depends on the cause and severity. Some men benefit from lifestyle changes, while others may need testosterone replacement therapy (TRT).
