Scientists find that the amount of sperm fell by a third in the last 20 years

Sedentary lifestyle, stress, overwork, anxiety disorders, cellular antennas??, All factors that could be contributing to our way of life has changed, for the worse, in the last decades.

Perhaps at one time they lived less because of the few advances in to cure some diseases already eradicated today, but it certainly lived better and with fewer worries. The question is whether this current lifestyle could threaten our very existence?

This is what led a group of French scientists to track 26,000 men between 1989 and 2005, who is performing a regular count amount of produced. The study found that in almost all cases, sperm production had fallen by almost a third as measured at baseline, 74 million to 50 million per milliliter, a steady decline rate of about 2%.

The study was published in the journal Human Reproduction and stresses that the researchers used databases of 126 fertility clinics in France, which were followed based on 26,600 samples from men with very low probability of having infertility problems.

In addition to low, also found that there was an increase in sperm deformed or “poor swimmers” in men with an average age of 35.

Although for the World Organization, an amount that could be considered “normal” around 15 million sperm per milliliter, for scientists of extra concern and believe that the rate of decline of 2% could cause problems much earlier than thought.

This type of study related to sperm count was always involved in some controversy, because many analysts believe that the procedures are not appropriate plural segments of the population. This is not a minor detail because in some different socio-economic sectors, the results could vary considerably.
