Low testosterone explained

What is Low Testosterone?

Testosterone levels decline naturally as you get older but for the first time in medical history, lifestyle factors are catching up with age as a risk factor. If testosterone levels drop too low, it can cause symptoms such as low libido, brain fog, loss of muscle mass, depression and more. The formal name for low T is hypogonadism.

How does testosterone replacement therapy (TRT) treatment work?

Function at your best

Restores your body’s testosterone levels to a healthy, balanced range. This isn’t just about “boosting”. It’s about correcting a deficiency so your body can function at its best for years to come. TRT is best and most safe when overseen by specialists like endocrinologists.

Improved physical performance

The changes you will notice include: increased muscle mass, reawakened sexual function, mental clarity, emotional regulation, focus and a drive to perform at your peak.

Lifestyle-forward treatment

TRT isn’t a band aid for suboptimal lifestyle choices. In order to get to the root cause of your symptoms, it’s important to address sleep, stress, diet and training alongside any TRT protocol to maximise results.

Men’s health is broken. We’re here to fix it.

Prof. Suks Minhas

MD FRCS Urol

"As a Consultant Urologist and Andrologist, my mission is to provide world-class, evidence-based care across the full spectrum of men’s health—encompassing sexual function, fertility, low testosterone, hormonal health, and urological wellbeing. Every man deserves access to expert, compassionate care regardless of background, ethnicity, or socioeconomic status. Equitable healthcare is not just an ideal—it is a responsibility."

DR. Ian Gallen

Endocrinologist & Medicine Advisor

"In the UK, we know that men are disproportionately less likely to seek medical help for various reasons, not least when it comes to conditions that may seem to carry a stigma. Heracles wants to break that cycle not just through treatment, but by equipping men with the knowledge and confidence to own their health and to thrive inside out."

Dr. Richie Kirwan

PhD Nutritionist

"Our modern food environment, our activity levels and the way we live our lives simply do not lead us towards health. My goal at Heracles is to help educate and guide men towards healthier food, movement and lifestyle habits that will lead them to the state of optimal health and function that they deserve, and that will help them live a longer, healthier, more fulfilling life."

FAQs & Common Concerns

Low testosterone (testosterone deficiency) also known as hypogonadism in men occurs when the body is unable to make enough testosterone. Low testosterone can significantly affect a man's health and quality of life.
The symptoms of low testosterone vary depending on when you develop it. In adult males, the most common symptoms include: erectile dysfunction, decreased sex drive, difficulty concentrating, decrease in muscle mass, low mood and more.
Low testosterone is diagnosed by a combination of medical history and symptoms review, blood tests and a physical where appropriate. The best place to start is with an initial Testosterone Blood Test and your doctor will take it from there.
Low testosterone is relatively common, especially as men age. A European study found that testosterone deficiency affected about 2 in 100 men aged 40 to 79 years and about 5 in 100 men aged 70 to 79 years. It is also more common in men who are overweight and men who are in poor general health with long-term health conditions.
TRT directly raises testosterone levels to the normal physiological range and relieves symptoms like fatigue, low libido, ED, depression, and muscle loss. Common forms of TRT include injectables, gels, creams, patches and implants.
No, you cannot take standard TRT if you are trying to conceive because it can drastically lower sperm production, even within a few weeks. Contact our medical team to discuss further. You may be able to try clomid or hCG treatment for low testosterone that preserves your fertility. Check out our guide to fertility-friendly low T treatment here.
The combination of TRT with hCG in men is not strongly evidence-based, despite a physiological rationale. While hCG mimics luteinizing hormone (LH) and may help maintain intratesticular testosterone and spermatogenesis during TRT, the clinical evidence supporting this approach is limited. Most studies are small, short-term, and observational, lacking the rigor of large randomized controlled trials needed to confirm efficacy and safety. Moreover, individual responses to hCG vary widely, and there is little long-term data on potential risks such as increased estradiol levels or overstimulation of the testes. As a result, the use of hCG alongside TRT remains a clinician-guided decision rather than a standard, well-supported medical practice.
TRT is generally safe for men with medically confirmed low testosterone when prescribed and monitored properly by a specialist. However, like any long-term hormonal therapy, it comes with risks and side effects that must be balanced against the benefits. Please consult with one of our specialists who will be able to conduct a thorough review of your suitability for TRT.
Yes! Testosterone deficiency is a hormonal condition that requires medical diagnosis and treatment. Our doctors are experts in low testosterone, fully licensed with decades of clinical experience between them.
When under medical supervision and with the appropriate protocols in place, yes. This is exactly what we do here at Heracles.
