Endocrine-disrupting chemicals found in breast milk

ScienceDaily (Sep. 25, 2009) — A comparison of breast milk samples from Denmark and Finland revealed a significant difference in environmental chemicals which have previously been implicated in testicular cancer or in adversely affecting development of the fetal testis in humans and animals. This finding is published in the International Journal of Andrology. In recent years a worldwide increase in testicular cancer has been noticed, but the cause remains unknown. In some countries, such as Denmark the prevalence of this disease and other male reproductive disorders, including poor semen quality and congenital genital abnormalities is conspicuously high; while in Finland, a similarly industrialized Nordic country, the incidences of these disorders are markedly lower. In the UK, almost 2,000 men are diagnosed with testicular cancer every year, and in the US this number is over 8,000. There is a wide variation in incidence rates of testicular cancer around the globe, and the reasons behind the observed trends are unexplained. Environmental endocrine disrupting chemicals (EDCs) are commonly found in fatty foods, paints, plasticizers, pesticides, and the byproducts of industrial processes, and in recent studies an association has been shown between some of these agents and male reproductive problems. To investigate whether EDCs could be related to such great differences in reproductive disorders between closely related countries, Konrad Krysiak-Baltyn and colleagues from Denmark, Finland, and Germany measured levels of 121 chemicals in 68 breast milk samples from Denmark and Finland to compare exposure of mothers to EDCs. …
