Recent advances in understanding endocrine disruptors: DDT and related compounds

Endocrine-disrupting compounds (EDCs) are environmental contaminants that modulate estrogen, androgen, and thyroid hormone receptor signaling and it has been hypothesized that human exposures to EDCs induce multiple adverse health effects. Some of these responses include male and female reproductive tract problems, obesity, and neurological/neurobehavior deficits. Extensive laboratory animal and some human studies support the EDC hypothesis. However, there is a debate among scientists and regulators regarding the adverse human health impacts of EDCs and this review highlights and gives examples of some of the concerns.
