Harvard: The presence of high levels of pesticides in fruits and vegetables can affect sperm quality. This is the conclusion of a study by US scientists published in the journal "Human Reproduction". This not only leads to reduced sperm count, but the amount of normally formed sperm is also reduced. Harvard
University researchers analyzed 338 semen
samples from 155 men who had visited a fertility clinic between 2007 and
2012. They also assessed their consumption of fruits and vegetables, and classified the pesticide content of these foods on the basis of national data. How foods were prepared (washed, peeled...) was also taken into account.
