‘They’ve invented a spurious pseudo-disease’: why are so many men being told they have low testosterone?

Social media influencers and booming men’s health companies are pushing the hormone as an answer to all ills. But is ‘low T’ really problematic – or something created to sell men a cure to a problem they don’t have?

A s a young man, Nick Dooley never thought about his hormones. He always considered himself “quite an outgoing, confident, chatty person”. Around the time he turned 30, however, Dooley began putting on weight and struggling with anxiety, “just slowly becoming a shell of my former self”, he says. By 38, he weighed 22st and had a range of health issues. “I spent most of my life sat in front of a TV, doing nothing, with zero motivation, and from how I was in my 20s, that wasn’t me. I knew something wasn’t right.”

In 2024, Dooley had a private medical exam, which flagged he had fatty liver disease and was producing low levels of testosterone. “It wasn’t something I’d ever really heard of,” he says. “So I started down a Reddit rabbit hole.” An NHS doctor told him his blood testosterone levels, at 11.2 nmol a litre, were “within range” (although guidance differs between trusts, NHS England generally considers between 8 and 30 nmol/L normal) and offered him antidepressants. “I knew that wasn’t going to fix me,” he says. Instead, Dooley signed up with Manual, an online men’s health company. After two quick blood tests and a virtual consultation, Manual, which has since rebranded as Voy, started him on testosterone replacement therapy (TRT).
