experts comment on the study of PFCs and women’s fertility, as published in Human Reproduction

The research found a link between blood levels of perfluorinated chemicals (PFCs), a class of chemicals commonly found in a wide range of products including food packaging and cookware, and the length of time taken for women to become pregnant.

Prof Alan Boobis, Toxicologist at Imperial College London, said:

“The study adds to the information available on the possible consequences of human exposure to PFCs. However, the relevance to human health needs to be considered within the context of all other available information. Only then will it be possible to determine whether and what action might be necessary.”

Prof David Coggon, Professor of Occupational and Environmental Medicine at the University of Southampton, said:

“This is an interesting preliminary finding that may or may not turn out to be important. We first need to see whether it can be confirmed in other studies. It would also be helpful to establish the main determinants of exposure to the two chemicals in the general population.”

Mr Tony Rutherford, Chair of the British Fertility Society, said:

“The finding that higher maternal plasma levels of perfluorinated chemicals, which are found in many consumer products, may be linked to reduced fecundity is interesting. This research shows a tenuous link in the delay to conception in women with the highest levels of two commonly used perfluorinated chemicals. This is an important finding and certainly warrants further detailed research, particularly in those trying for a family. This study emphasises the importance of remaining vigilant to potential environmental factors that may impact on fertility.”
