For Men: Information For Future Fathers

2011: New research says chemicals released from some plastics may be harming human reproduction

By Melanie Hundley
A new research article appeared in the June 2011 issue of Human & Experimental Toxicology that may be of interest to men who want to be fathers.  A group of researchers, Pant et al, in New Delhi analyzed the “environmental and experimental exposure of phthalate esters” to human sperm.  In this review, we will learn more about phthalates (THAL-ates), look at their study, and see their results.

What Are Phthalates?

According to Pant and the research team, phthalates are chemical additives that may be used to increase flexibility in some manufactured plastics.  Phthalates are believed to be released from some

2011: Chasing Better Autism Data

Finnish data model offers new insight on autism in children

A major consideration in any research project or audit is selecting the data to analyze.  Once the data population is determined, various methods of sampling are used to spot trends and draw conclusions.  Deciding where to obtain the data is critical to the quality, trust, and peer acceptance of the results.

That is why a new report coming out in the August 2011 issue of the Journal of Autism and Developmental Disorders should prove very interesting for future studies of autism.  Lampi, Sourander, Brown, et al's excitement about the Finnish Prenatal Study of Autism and Autism Spectrum Disorders (FIPS-A) appears justified.  Having a comprehensive collection of medical data together with blood samples sounds wonderful for any such research. 


Lampi and the other researchers are affiliated with the University of Turku, Columbia University, or the National Institute of Health and Welfare in Finland.  I will reference the team as Lampi et al in this article for brevity.

2011: Did Exposure to PCBs Cause Thyroid Disease?

New research reports on the possible link between thyroid disease and PCBs

By Melanie Hundley

If you were a tot in the 1960s in the U.S., your frame of reference for PCB (polychlorinated biphenyl) chemicals may have been similar to mine.  PCBs were around, but you were unaware of them. You probably did not hear about the cattle feed disaster in Michigan in 1973-74. At best, about 1980, your parents may have pointed to the big gray cylinders mounted on telephone poles (transformer pots) and told you to "never touch one of those if you find it on the ground."


Eventually more people did hear about the health hazards of PCBs, but news moved slowly in those olden days.  We had no ubiquitous Internet, limited news sources, and no online MSDS sheets to share that type of information.
