On the question of environmental “endocrine disruptors” as an explanation for a decline in semen quality, Professor Hart added:
“The extent of the risk posed by environmental endocrine disrupters is still unclear, but some researchers do attribute the perceived decline in sperm counts to these chemicals within the environment. We do not have any evidence to suggest such a link in our study, but we do intend to measure the fetal exposure to endocrine disrupting chemicals from maternal blood that was stored in 1990, prior to the study recruits’ birth, and to relate these chemical exposures to the men’s semen counts in 2012-3.”
