Fertility of Prague's men is smaller

Academy of Sciences of the Czech Republic made a survey which is really unique in the whole Europe. Scientists tried to find the connection with the environment, especially with the quality of air, and men’s fertility. The research, testing 60 students from Prague, 90 students from Brno and 70 police officers from Prague, took two years.

The results show that men is Prague are less fertile than men in Brno. Their sperms are slower and less vital and more often they have damaged heads. The damaged head of a sperm, which carries the genetic information, can lead to spontaneous abortion.

It is caused by the bad quality of Prague’s air that is polluted by heavy traffic in the capital. The scientist also point out that second reason that reduces the fertility is smoking and bad lifestyle. Good news is that the bad air does not damage the sperms forever.
