Slower sperm 'more fertile'
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.The realisation that the most active sperm are not necessarily the most fertile has produced an advance in fertilty treatment - and a baby daughter for a couple, Tony and Anne McIntyre, who believed they would never be parents.
Dr Simon Fishel and Stephen Green from Nottingham University's reproduction unit have devised a 'real time' computer programme for identifying the sperm most capable of fertilising an egg.
