Testosterone deficiency is often difficult to diagnose due to its wide range of symptoms, many of which can overlap with other health issues.

Key symptoms to watch out for

Fatigue & low energy
Constant tiredness and a lack of energy could be linked to testosterone deficiency, especially if it's not due to other lifestyle factors.¹
Low mood & depression
Testosterone plays a role in regulating mood. A drop in testosterone can lead to irritability, low mood, or even depression.¹
Sleep issues & brain fog
Difficulty sleeping or waking up tired may coincide with mental cloudiness or inability to focus - both signs of a hormone issue.¹
Loss of morning erections
A more specific indicator is the loss of regular morning erections, a hallmark of declining testosterone levels.¹
Reduced libido & sexual desire
A noticeable decrease in sexual interest, whether with a partner or solo, could point to a hormonal imbalance.¹
Loss of vitality
Many people report feeling like they've lost their "spark," lacking enjoyment in activities they used to love.¹

The numan take

If you’re experiencing one or more of these symptoms, it’s worth considering testosterone deficiency as a possible cause. Start by taking a blood test.

Does masturbation decrease testosterone?

You’ve heard the rumours about masturbating. At Numan, we’ve heard them all. Causing blindness, baldness, erectile dysfunction, or infertility. None of these are true, by the way.
