Researchers at the University of Missouri-Columbia have found the sperm count among men living in more rural areas, such as the Midwest, is inferior to that of men living in more populated areas of the country. Doctor Shanna Swan, an epidemiologist at the University of Missouri, took part in the research. She believes farm chemicals might be partly to blame. Doctor Swan says researchers believe agricultural chemicals could be contributing to this decrease in semen quality. Further studies are being conducted to determine whether this is the case.
