QUICK ANSWER
Low testosterone can add to anxiety, tension and a shorter fuse in some men, and low levels are linked to higher anxiety scores in studies. But anxiety usually has other causes too. A blood test is the only way to know whether your hormones are really part of it.
Find the test that fits your symptoms →As of July 2026.“Can low testosterone cause anxiety?” is a question a lot of men bring to a hormone test. This guide sticks to what the NHS and the research actually say, and to what a blood test can and cannot tell you.
You feel wired. On edge for no clear reason. A short fuse over small things, and a mind that will not settle at night. It is a fair question to ask whether your hormones are part of it.
1. Can low testosterone cause anxiety?
It can play a part. Testosterone is the main male sex hormone, and it acts on brain regions that shape mood and the stress response. When levels drop too low, some men feel more tense, restless and irritable. The NHS groups these mood changes under what it calls the “male menopause”.
“A GP will ask about your work and personal life to see if your symptoms may be caused by a mental health issue, such as stress or anxiety.”
— NHS, on assessing “male menopause” symptoms
The research points the same way, gently. A 2012 study in Endocrine Journal compared 39 young men with low testosterone against 40 healthy men. The men with low testosterone scored significantly higher for anxiety. It is a real link, but a small study.
Here is the honest catch. In that same study, six months of testosterone treatment improved depression, yet the change in anxiety was not statistically significant. So low testosterone can feed anxiety, but it is rarely the whole story on its own.
2. What does low-testosterone anxiety feel like?
Low testosterone and anxiety share a lot of ground. That overlap is exactly why they are so hard to tell apart without a test. The signs men most often report include:
- Feeling on edge or wired. A background tension that sits there even when nothing is wrong.
- Irritability. A shorter fuse than normal, snapping at small things.
- Poor sleep. A restless mind at night, then tired days that make everything feel worse.
- Low drive and libido. A drop in sex drive is one of the more specific pointers to hormones.
- Brain fog. A fuzzy, slowed-down feeling, covered in our brain fog guide.
If several of these ring true, our fuller guide to low testosterone symptoms in men walks through the warning signs in detail.
3. Anxiety has other causes too, not just testosterone
Here is the trap. Blaming your hormones feels tidy, but it is often wrong. The NHS notes that these symptoms may come from stress or anxiety in their own right, not a hormone problem at all. Several other blood markers can produce the same wired, tense feeling.
- Overactive thyroid. An overactive thyroid speeds everything up and is a classic cause of restlessness and a racing heart. A thyroid blood test rules it in or out.
- Cortisol. The stress hormone. Chronic stress can raise cortisol and lower testosterone at the same time, which our cortisol guide explains.
- Vitamin B12 and vitamin D. Low levels of either are linked to low mood and a jittery, drained feeling, and both are common and easily missed.
- Blood sugar swings and caffeine. Big dips after sugary food, and too much coffee, can copy the exact feeling of anxiety.
This is the whole reason to measure rather than guess. Two men with the same wired feeling can have two different causes, and the fix for one does nothing for the other. Our guide to the physical causes of anxiety covers the full checklist.
4. How to tell if it is your hormones
You cannot feel a testosterone level, so a symptom on its own proves nothing. A blood test turns a guess into a number. For an anxiety question, the markers worth reading together are:
- Total and free testosterone. The hormone itself, and the active fraction your cells can actually use.
- SHBG. The protein that binds testosterone and sets how much is free to work.
- Cortisol and thyroid. The stress hormone, plus TSH and Free T4, which catch the causes that mimic hormone anxiety.
- Vitamin B12 and vitamin D. The nutrient shortfalls that leave you feeling wired and drained.
Timing matters for testosterone. Test in the morning, ideally before 10am and fasted, because levels are highest then and drift down through the day. Our guide to the best time to test testosterone covers the rules. A full blood count can also flag anaemia, which drains energy and frays the nerves.
Testosterone and SHBG sit in Helvy’s Complete Male Hormones panel (£119), while cortisol, thyroid, B12 and vitamin D sit in the General Energy & Wellness panel (£149). To check the mix that fits your symptoms, the build-my-test tool matches you to the right markers. All are home finger-prick tests, with results in about five working days from UKAS-accredited UK laboratories.

Put a number behind how you feel
Helvy’s home blood tests read testosterone alongside the other markers that shape mood and tension, with clear, plain-English context. So you can see whether your hormones are the issue, or whether something else is behind how you feel. Results in about 5 working days from UKAS-accredited UK laboratories.
Frequently asked questions
Can low testosterone cause anxiety?
It can contribute. Low testosterone is linked to feeling tense, on edge and irritable, and a 2012 study found men with low testosterone scored higher for anxiety than healthy men. But anxiety is non-specific, so a blood test is needed to know if hormones are the real cause. This is general information, not medical advice.
Does raising testosterone fix anxiety?
Not reliably. In the 2012 study, six months of testosterone treatment improved depression but did not significantly change anxiety. That is a strong hint that anxiety usually has more than one cause, which is why measuring several markers together matters more than treating one number.
Could my anxiety be something other than testosterone?
Very possibly. An overactive thyroid, high cortisol from chronic stress, low vitamin B12, low vitamin D and blood sugar swings all produce a similar wired, tense feeling. The NHS notes these symptoms often come from stress or anxiety rather than hormones. Testing several markers together is the only way to separate them.
Which blood test should I take for anxiety?
For an anxiety question, it helps to read testosterone, SHBG, cortisol, thyroid, B12 and vitamin D together, since any of them can be behind how you feel. The build-my-test tool matches you to the right markers. If a result is abnormal or your anxiety feels severe, speak to a qualified clinician.
