Abstract
Testosterone is often associated with muscle, libido, and physical energy - but its role in mental health is just as important. At Omniya Clinic, we frequently see men who feel "flat," unmotivated, or emotionally overwhelmed, only to discover that low testosterone was an underlying factor. Testosterone Replacement Therapy (TRT) has been shown to support mood, mental clarity, and even reduce symptoms of depression and anxiety - though it’s not a recognised treatment for these conditions, nor a substitute for therapy.
In this article, we explore how TRT may influence mood and mental function, the research behind it, and important considerations if you're navigating symptoms of low motivation, brain fog or anxiety. For a full overview of treatment options, visit our Testosterone Replacement Therapy page.
Testosterone’s Role in Brain Chemistry
Testosterone is more than a sex hormone. It interacts with key neurotransmitters such as:
- Serotonin: which regulates mood and emotional stability
- Dopamine: which influences pleasure, motivation, and reward
- Cortisol: testosterone helps modulate the stress hormone response
Low testosterone can disrupt this delicate chemical balance, leaving men feeling anxious, irritable, or mentally foggy. It’s also associated with reduced hippocampal volume - the area of the brain linked to memory and emotional processing.
Symptoms commonly linked to low testosterone include:
- Loss of motivation or drive
- Difficulty concentrating (“brain fog”)
- Low mood or persistent sadness
- Irritability or emotional volatility
- Anxiety without a clear trigger
If you’re experiencing these symptoms alongside fatigue or reduced libido, it may be time to explore testing. Learn more about early indicators in our guide to Early Warning Signs of Low Testosterone.
Evidence for Treating Depression and Anxiety
There is increasing evidence that testosterone influences mood - particularly in men with diagnosed testosterone deficiency. While many headlines suggest TRT can alleviate depression or anxiety, the data is still evolving and subject to clinical context.
Several studies have reported a moderate improvement in depressive symptoms when testosterone is administered to men with low baseline levels. However, more long-term research is needed to fully understand the extent and sustainability of these effects.
While these findings are promising, it’s important to remember that TRT isn’t a replacement for therapy or medication when clinically indicated. Instead, it may complement a broader mental health strategy - especially when hormone imbalance is a contributing factor.
What’s encouraging is the feedback we hear from our own patients. Many describe a significant lift in energy, emotional balance, and clarity within the first few months of treatment. Partners often notice the change too - greater engagement, improved communication, and a restored sense of presence and resilience.
We frequently hear statements like:
- "I feel like myself again."
- "I’ve got my spark back."
- "I didn’t realise how much my mood had changed until I started feeling better."
This doesn’t happen overnight - but it does happen with the right guidance, support, and review structure.
At Omniya, we take a holistic view - addressing both hormone imbalances and mental wellbeing. If you're interested in personalised guidance, visit our TRT Process to see how we approach care.
A New Chapter in Wellbeing
There’s something profoundly validating about understanding that your symptoms have a biological basis. For many men, finding out that low testosterone is contributing to how they feel emotionally provides not just relief - but hope.
TRT opens the door to rebuilding confidence, resilience, and motivation. It can act as a catalyst, giving men the momentum to improve other areas of their lives - including exercise, diet, sleep, relationships, and even work performance.
The transformation isn’t just internal. Over time, you may notice:
- You’re more present in conversations
- You handle stress more calmly
- You’re more productive at work
- Your outlook becomes more optimistic
- You take more pride in your daily routine
These benefits aren’t just physical - they’re deeply psychological and emotional. And while TRT is not a “quick fix,” it can provide the stable platform needed to make lasting, positive change.
If you're still unsure, speaking with someone who understands both the science and the emotional toll can make all the difference. Our consultations are discreet, thorough, and designed to give you clarity.
Risks to Watch For
While TRT may offer emotional benefits, it’s not without risks. Some men experience transient mood swings, increased aggression or emotional overstimulation during the early phase of treatment - usually related to rapid hormonal shifts or dosing issues.
Potential psychological side effects can include:
- Short-term anxiety or restlessness
- Sleep disruption (especially if oestradiol levels aren’t monitored)
- Worsened mood if oestrogen has increased
That’s why careful monitoring is key. At Omniya, we follow up closely in the first 6–12 weeks to assess mood, cognition, and mental health changes.
If you’re already on antidepressants, it’s important to discuss potential interactions. Our clinical team works collaboratively with your GP or psychiatrist where needed.

FAQs
Can TRT make anxiety worse?
In the early stages, some men experience heightened anxiety as hormone levels adjust - especially if oestrogen rises too quickly. These effects are usually temporary and resolve with dosage refinement. Long term, many patients report reduced anxiety and improved emotional regulation.
Does testosterone affect motivation?
Yes. Testosterone plays a role in regulating dopamine - the neurotransmitter linked to reward and motivation. Men with low testosterone often report apathy or disinterest in activities they used to enjoy. TRT may help restore drive, productivity, and enthusiasm.
Taking the Next Step
TRT is not a cure-all, but for men with hormone-related mood symptoms, it can be life-changing. Whether you’re feeling disconnected, foggy, or constantly low, investigating your testosterone levels is a practical place to begin.
