According to recently published scientific data, a constant decline in sperm concentration was observed in France between 1989 and 2005, at a rate of 32.2% in total or a yearly rate of 1.9%. In addition, lower percentages of normal sperm morphology were recorded during the same 17-year period.
These results are in accordance with the falling trends in sperm concentration observed in other countries, e.g. Israel, New Zealand, Tunisia and Finland.
The experts’ views tend to correlate the deterioration of semen quality with environmental or other factors regarding alterations in nutritional habits, psychological stress or the presence of infections.
These alarming data raise concerns about the fertilizing potential of the future generations. The preventive evaluation of sperm quality by means of a reliable semen analysis in young men may lead to the diagnosis of problems that could possibly be resolved at an early stage. Moreover, the preventive freezing and cryopreservation of several semen samples may prove useful as an action of foresight against any negative future development.
