Science Weekly · Is male testosterone in freefall? · 9 Jul 2026 podcast

Why is testosterone falling? matched

Do the authors themselves have any theories as to what's going on? matched

How plausible do you find this explanation for that trend for those data? matched

And do you think there might be anything else going on? matched

Have scientists or have doctors got any sense of what a decline in testosterone like this might mean for male reproductive health? matched

Coming up, testosterone. matched

How low could it go? matched

Hannah, recently a lot's been made of male testosterone, not least because companies are selling therapies for low T, and it's something we've talked about on the podcast before. matched

Do results like this suggest that maybe there is a reason for men to be taking extra testosterone? matched

So Hannah, where do we go from here? matched

I mean, should this be a wake-up call for scientists, for doctors and maybe society even more? matched

How do we begin to figure out exactly what's going on and if there is a fertility crisis here? matched

If we don't tackle this, though, Hannah, and if we keep seeing this 1% per year decline in testosterone that these scientists say they've observed, where does that leave us in another 50 years? matched

Hannah, it's fascinating stuff. matched

It's going to be a great one to watch for the next few years. matched

Thanks very much. matched

Thanks again to Hannah Devlin. matched

And that's all from us. matched
