Real men come fast... and often

Scientists today recommended men should ejaculate more often if they want to keep their sperm healthy.Research showed that men who had some form of sexual activity daily had better quality sperm than a control group who had been told to abstain for three days at a time.
The study was aimed at helping couples improve their chance of getting pregnant and concluded that men cut their chances if they hold off sexual activity.
Experts said some couples seemed to believe men should hold their sperm "in" for days or weeks to improve its quality.
But the Australian research shows the chances of pregnancy are lower if a couple waits for long stretches between sex sessions.
Dr Allan Pacey, senior lecturer in andrology at the University of Sheffield and secretary of the British Fertility Society, said it was important to understand the "trade-off" between genetic damage to the sperm and quantity.
Dr Pacey said some couples believed they had a better chance of achieving pregnancy if they waited a long time between making love.
"I remember one couple in which the woman would only let the man ejaculate when she was in her fertile period, so the poor chap was going without for almost a month at a time.
"But if sperm is released in a steady stream, the sperm that is ejaculated are newer and less damaged.
"If you are a guy who has high DNA damage and a decent sperm count, it is probably in your interest to ejaculate every day.(more to come from thelondonpaper)
