hi girls. I don't remember if I posted this already. I've read that taking 1000mg daily of vitamin C improves sperm motility by preventing clumping of sperms. This has the effect of doubling sperm count. I read 2 studies on human males that confirmed it. Can't say for sure of course if it will help but it's good to take as a supplement in the winter anyway as it may help prevent colds. My OH started taking it a month ago and so did I. It's so cheap, buy it at your local chemist, it comes as a tube of fizzy tablets. I was intrigued by this one! x
