There has been increasing evidence on the global decline in human sperm quality over the past few decades. In the most recent report, an international study group performed a systematic analysis of the current trends in sperm counts. This comprehensive study involved 42,935 men with semen samples spanning over 40 years. They reported a significant decline of 50– 60% in sperm counts amongst men from North America, Europe, Australia and New Zealand. This latest finding has sparked even greater concern over the reasons behind the apparent decline in the sperm count of Western men.
