Humans could become extinct if sperm counts in men from North America, Europe and Australia continue to fall at current rates, a doctor has warned. Researchers assessing the results of nearly 200 separate studies say sperm counts among men from these areas seem to have halved in less than 40 years. Taken together these factors may have created a false view of falling sperm counts. He said: "I've never been particularly convinced by the many studies published so far claiming that human sperm counts have declined in the recent past." Dr Levine says that there is an urgent need to find out why sperm counts are decreasing and to find ways of reversing the trend.
