This paper deals with the contamination of our environment with thousands of both natural and man-made chemicals which affect the endocrine system of humans and animals. These so-called endocrine disrupting chemicals (EDCs) are thought to mimic or block the action of hormones and therefore disrupt sexual development in utero. EDCs are organochlorine pesticides, dioxin compounds, polychlorinated biphenyls, alkyl-polyethoxylates, plastic additives and phytoestrogens (occurring naturally in foods: isoflavones, coumenestans and zearalenone). The structure of zearalenone is similar to the structure of estrogens and it enables binding to the estrogenic receptors. DNA laddering on gel electrophoresis was present 12 h after dosing thus indicating a conclusion that there was apoptosis. Apoptosis is the principal mechanism contributing to germ cell depletion and testicular atrophy following zearalenone exposure.
