BACKGROUND Previous inconsistent results suggest that menstrual cycles may be
disturbed by exposure to polychlorinated biphenyls (PCBs) and 1, 1-dichloro-2, 2-bis (p …

It has been hypothesized that environmental exposure to synthetic estrogenic chemicals and
related endocrine-active compounds may be responsible for a global decrease in sperm …

Background Polychlorinated biphenyls (PCBs) are one of the various classes of
environmental contaminants that have been observed to affect oocyte maturation. PCBs are …

This study evaluated the estrogenicity of polychlorinated biphenyls (PCBs) present in
environmental media and human tissue and assessed exposure pathways for PCB-derived …

Endocrine-disrupting chemicals are known to interfere with normal reproductive function and

Growing evidence suggests that persistent environmental chemicals such as
polychlorinated biphenyls may adversely affect human fecundity. The purpose of this study …

BACKGROUND: During the last decades, there has been concern that exposure to
endocrine disruptors, such as persistent organochlorine pollutants (POPs), may contribute to …

Millions of pounds of polychlorinated biphenyl (PCB) compounds have been produced in
multiple countries for industrial applications over the last several decades. PCB exposure …
