Nitric oxide is the signal that keeps every blood vessel in a man's body open. Losing it is the first step towards heart disease and erectile dysfunction, and it happens years before anything shows up on a scan. Here's what it does, why it falls, and what your blood vessels actually need.

Millions of men are on GLP-1 drugs like Ozempic and Mounjaro, but few know what they do below the belt. In men carrying excess weight, they tend to raise testosterone, may improve sperm quality, and probably help erections. Here's what the latest evidence shows,

Daily tadalafil may support erections, prostate symptoms, erectile tissue and vascular health - but does that make erection pills a longevity drug? Here is what the evidence really shows.

Prostate cancer is the second biggest cancer killer of men, and the UK has just decided not to screen most of them for it. The doctors who treat it mostly screen themselves. Here is why that gap matters, and the one question that decides the answer for you.

What if your erections are the earliest warning sign your body gives you about your cardiovascular health, years before anything shows up on a standard lipid panel?

In Episode 1 of Men's Health Matters, our co-founder, Christos, sits down with Jordan, a citizen scientist who has personally tested over 1,000 supplements in pursuit of one thing: understanding how to optimise nitric oxide and protect erectile function for life. We talk all about erection health, supplements, and the online men's health communities where thousands of men are quietly trying to figure this stuff out for themselves.

Most lists of foods for erections give you a shopping list with no science. This guide breaks down the active compounds, the mechanisms, the dosages used in research, and practical meals you can actually make.

The biohacking world loves complexity. Cold plunges, red light panels, peptide stacks, hyperbaric chambers. Meanwhile, the single intervention with the broadest evidence base across testosterone, cardiovascular health, erectile function, sleep, and mood is something you already know how to do. Walking.

Most men assume that waking up with an erection means everything is working. And that not waking up with one means something might be wrong.

It sounds reasonable. Morning erections are the one nocturnal erection you can actually notice. They are the visible tail end of a process that runs all night, so it makes sense to treat them as a signal.

But our data tells a different story.

One of the most common questions men ask when starting testosterone replacement therapy is how quickly they will see results. The honest answer is that it depends on what you are measuring.

Why current penile rehabilitation protocols may be under-dosed, and what 20,000 nights of erection data suggest about the oxygenation threshold your body actually needs.

Sleep is the foundation of men’s health, influencing night-time erections, testosterone, fertility, energy, and wellbeing. Learn practical ways to improve sleep.
