PCBs, other pollutants may play role in pregnancy delay
Date:11/13/2012

ddition to researchers at the NICHD, the study also included investigators from the Texas A&M Health Science Center, College Station, The Ohio State University, Columbus, Emory University, Atlanta, and The EMMES Corp., Rockville, Md.

To conduct the study, the researchers enrolled 501 couples from four counties in Michigan, and 12 counties in Texas, from 2005 to 2009. The couples were part of the Longitudinal Investigation of Fertility and the Environment (LIFE) study, established to examine the relationship between fertility and exposure to environmental chemicals and lifestyle. An earlier analysis from the LIFE study found that high blood levels of lead and cadmium also were linked to pregnancy delay.

The women taking part in the study ranged from 18 to 44 years of age, and the men were over 18. Couples provided blood samples for the analysis of organochlorines (PCBs) and perfluorochemicals (PFCs). Women kept journals to record their monthly menstrual cycles and the results of home pregnancy tests. The couples were followed until pregnancy or for up to one year of trying.

The researchers calculated the probability that a couple would achieve pregnancy by using a statistical measure called the fecundability odds ratio (FOR). The measure estimates couples' probability of pregnancy each cycle, based on their blood concentration of the compounds. A ratio less than one suggests a longer time to pregnancy, while a ratio greater than one suggests a shorter time to pregnancy.

The researchers examined PCB congeners, which are single, unique well-defined chemical compounds in the PCB category.

The lowest FORs were seen for couples in which the females were exposed to PCB congener 167 (FOR 0.79); and in which the males were exposed to PCB congener 138 (FOR=0.71).

For each standardized increase in chemical concentration the researchers measured, the odds of pregnancy declined by 18 to 21 percent for females exposed to PCB con
