The Testosterone Testing Boom: What Men Need to Know

A surge in advertising from companies like Voy, plastered across London’s Underground and online, is prompting men to check their hormone levels. While increased awareness of men’s health is a positive step, experts caution against jumping to conclusions and emphasize the importance of comprehensive testing and lifestyle adjustments before considering testosterone replacement therapy (TRT).

The Rise of At-Home Testosterone Tests

Companies such as Voy, Numan, Optimale, Balance My Hormones, Alphagenix, and Urban TRT are offering at-home blood test kits marketed towards men concerned about low testosterone. These typically involve an initial test to determine testosterone count, a follow-up confirmation test, a medical consultation, and potentially a subscription to TRT. The global testosterone industry was worth $114.3 million in 2025, with blood tests being the leading segment of the market, according to research firm Future Market Insights. [1]

What Does Testosterone Do?

Testosterone plays a crucial role in numerous bodily functions for men, including hair and muscle growth, bone density, fat distribution, mood regulation, red blood cell production, and sexual development. Women as well produce testosterone, but in significantly lower amounts. [1]

Symptoms of Low Testosterone

Testosterone levels generally decline with age. Approximately 10 to 30 percent of men experience a decline by age 40. [1] Common symptoms of testosterone deficiency include low mood, brain fog, fatigue, and low libido. Other potential indicators include increased fat around the waist, erectile dysfunction, and loss of muscle mass. But, these symptoms are often vague and can be attributed to various other factors, such as poor sleep or underlying medical conditions. [1]

The Risks of Relying on Basic Blood Tests

Experts express concern that many online companies offer basic blood tests that provide an incomplete picture of a person’s overall health. Low testosterone is linked to conditions like type 2 diabetes and metabolic syndrome, which increase the risk of cardiovascular disease. Testing testosterone in isolation, without considering other health markers, can lead to unnecessary prescriptions and heightened health anxieties. [1] It’s also crucial to have testosterone levels tested in the morning (between 5am and 8am) when they are at their highest, as timing can affect results. [2]

What to Do If You’re Concerned

If you’re experiencing symptoms of low testosterone, it’s essential to consult a registered healthcare professional for a comprehensive blood screening. This should include assessments of kidney function, thyroid levels, vitamin D, and zinc, all of which can impact testosterone production. Prioritize lifestyle changes, such as stress management, improved sleep, a healthy diet, and regular exercise, as these can often reverse low testosterone levels. [1]

Understanding Testosterone Replacement Therapy (TRT)

TRT, typically administered via injection, suppresses the body’s natural testosterone production. Once started, it generally requires lifelong continuation and regular health monitoring to manage potential risks like raised blood pressure and cholesterol. [1] TRT can also impact fertility, and patients may require additional hormone treatments to maintain sperm production. [1] The cost of TRT can be substantial, generally exceeding £100 per month on a subscription basis.

NHS Access to TRT

Access to TRT on the National Health Service (NHS) can be limited due to the need for ongoing follow-up care and competing healthcare priorities. The NHS also lacks dedicated men’s health specialists, requiring patients to navigate multiple specialties for diagnosis and treatment. [1]

Addressing the Stigma

Despite the potential risks, companies like Voy argue that their advertising campaigns aim to reduce the stigma surrounding men’s hormonal health and encourage open conversations. [2] However, some find the messaging insensitive, particularly given the historical dismissal of women’s hormonal concerns. [4]

increased awareness of testosterone’s importance in men’s health is a positive development. However, it’s crucial to approach testing and treatment with caution, seeking guidance from qualified healthcare professionals and prioritizing a holistic approach to well-being.
