Scope

The last decades have shown that the course of pregnancy and fetal development can be sensitive to chemical exposures. It is furthermore evident that the environment during pregnancy determines, to a large degree, the developmental trajectories of the fetus, alters the functioning of the offspring’s organ systems and hence health later in life. Here the recognition of the potential for epigenetic moderation by chemicals opens up for a deeper understanding of the developmental origin of health and disease.   

Many couples have difficulties in becoming pregnant, and the environment may play a role in this case too. Parenthood is increasingly pursued at the end of the reproductive years. At this time in life, the male and female reproductive systems have had more years of occupational and environmental exposures, but we know little about the potential consequences for fertility and fetal development.

The number of existing chemicals is enormous. Establishing a toxicological database that is adequate for hazard and risk assessment for each chemical poses one of the largest challenges to the field. We therefore need to establish methods that enable hazard prediction based on limited or even no testing in biological systems.

To continue the development of the field of reproductive and developmental toxicology, this research section encourages interdisciplinary research between disciplines, ranging from material and chemical science, exposure assessment, epidemiology, in vitro and experimental animal science, basic and molecular biology, in silico modeling, and risk assessment.

The section covers contributions devoted (but not limited) to:

•        Deepening our understanding of the pathological pathways and mechanisms underlying fetal programming, e.g. to feed into development of adverse outcome pathways (AOPs) and in silico methods

•        Developing in vitro tests, ultimately to cover the full reproductive cycle

•        Opening up our understanding of interaction between exposures and between life stages of exposure, e.g. by studying combinations of exposures rather than single exposures, and if prenatal exposures increases the susceptibility to (other) exposures later in life

•        Studying the consequences of early exposures on health late in life

•        Characterizing functional changes in life after birth, e.g. relating to the function of offspring cardiovascular, immune, kidney and female and male reproductive systems etc.

•        Investigating how exposures of the parents prior to conception may contribute to effects in the offspring, e.g. male mediated developmental toxicity

•        Exploring the many birth cohorts worldwide, including the possibility to take advantage of the increasing age of the children, enabling investigation of health in generations.

•        The study of less common exposures, including new types of chemicals, occupational factors and exposure by inhalation.

•        Toxicological studies investigating male and female fertility in adulthood, including the reversibility of effects

•        The Study of the role of the placenta in developmental toxicity of chemicals
