Since 1974, there has been mounting evidence of declining human sperm counts in several industrialized populations. But there are marked differences in occurrence and timing between regions, suggesting an environmental effect. Sperm counts have not yet declined to levels where fertility is severely threatened, but how serious is the problem and what might the future hold for our species?
