Womb Mess by PCBs

July 2, 2012

It is not surprising that chemicals may affect biological functions. In a new study, by Andrea Gore of the University of Texas on rats, has shown that PCB-induced brain changes delayed puberty in male offspring and disrupted reproductive cycles in the adult female offspring. Rats and humans are very similar biochemically in the hypothalmus whose functions influence reproduction which is what she studied. In addition, the researchers identified five genes that PCB disrupted. Gore said that all five are critical to the normal hypothalamic control of reproduction.
