Comparison of the content of chlorinated pesticide residues in human semen, testicles and fat tissues.

Studies were undertaken to determine the residues of chlorinated pesticides in human semen, testicles and fat tissues. Samples of semen were taken from a random population and samples of tissues at surgery. A preliminary estimation was made to assess the level gradient of environmental pollutants in these types of specimens characterized by a different fat content. Pesticides were considered to show an affinity to fat. The results are an early stage in a programme for a detailed analysis of the effect of pesticides on human reproductive ability and on the value of genetic material.
