Effects of chemical exposure on male reproductive organogenesis and functions

点击翻译按钮获取中文摘要

Effects of environmental exposure to some selected chemicals on male reproductive organs and functions were examined in non-exposed general subjects. Urinary concentration of the target chemicals and/or their metabolites was used as a biomarker of exposure and anogenital distance (AGD) at birth and semen parameters was used for the assessment of effect on fetal and adult exposure to the target chemicals, respectively. In utero exposure to phthalate di(2-ethylhexyl) was found to shorten AGD of male newborn. Exposure to pyrethroid insecticides was found to decrease semen motility in male partners of infertile couples. These findings were assumed to be related to interference on testosterone action or production due to exposure to these chemicals at environmental levels.
