[Impact on environmental factors on the reproductive system and fetal development].

A literature review discusses the effect of selected environmental factors on women reproductive system, fetal development and growth. According to recent reports, 2-3% of newborns have congenital malformations. These malformations are caused by interaction of genetic and environmental factors. Exposure of paternal or maternal organisms to environmental hazards may damage germ cells or interfere fetal development, resulting in malformation of various organ systems. Since environmental hazards exposures are complex, it is difficult to establish the primary effect of single factor. Factors, that are known to increase the risk of congenital malformations, preterm delivery or spontaneous abortion, are classified into five groups--psychological, social, biological, physical and chemical factors. The governments of most counties recognize the effect of hazardous environmental factors on public health as global problem. World Health Organization encourages researches, aimed at evaluation of various environmental factors impact on health of pregnant women and their offsprings.
