Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

TESTICULAR injuries sustained during contact sports such as rugby and football may affect hormone levels and cause infertility, according to an American study of 179 infertile men reported in Fertility and Sterility.

Thirty of the men said they had been injured at some time, most commonly during their teens, compared with no testicular injuries in a control group of 46 fertile men. Levels of oestradiol, a female hormone, were 19 per cent higher in infertile men with a history of testicular damage than in infertile men with no injuries. They were also 25 per cent higher than levels in fertile men.
