Sperm counts in Western men ‘have dropped considerably since 1970s’

26th July 2017

Sperm counts among men in Western countries have fallen by more than half in the last 40 years, according to a new study.

Led by the Hebrew University of Jerusalem and published in the Human Reproduction Update journal, the study assessed the results of 185 previous pieces of research conducted between 1973 and 2011.

A 52.4 percent decline in sperm concentration and a 59.3 percent fall in total sperm count was identified in men from North America, Europe, Australia and New Zealand, with the rate of decline continuing or even accelerating.

Although no similar decline was seen in South America, Asia and Africa, it was noted that far fewer studies of sperm quality have been carried out in these regions, meaning the problem may also spread to these areas.

The researcher said it remains unclear why this decline is taking place, but it was noted that it could be indicative of a declining standard of general health in these men.

Lead researcher Dr Hagai Levine told BBC News: "Eventually we may have a problem, and with reproduction in general, and it may be the extinction of the human species."
