Toxic infertility xenobiotics

Toxic infertility as used here refers to adverse effects on the reproductive systems of human males and females that result from exposure to xenobiotic single chemicals and chemical mixtures. This infertility may be because of direct toxic effects on the male or female reproductive organs and endocrine systems, or on the developing fetus such that the fetus cannot be either conceived or carried to term after conception. Developmental toxicity, the onset of adverse effects on the developing fetus or child after birth are discussed in Chapter 24. 

Xenobiotic exposures can impact female fertility in humans in several ways. Much of the published research on xenobiotic impact on female infertility has concerned itself with the effects of pesticides. The effects, however, are just as applicable to other toxicants. Interference with any of the following six processes adversely impacts fertility ... 

Human infertility can result from the action of xenobiotic chemicals on the female reproductive system, the male reproductive system, attack on the fetus, and the induction of effects in utero that are manifest during adulthood, giving rise to a programmed infertility. Spontaneous abortion can ensue when pregnant women are exposed to toxic chemicals such as those in disinfection byproducts produced by the chlorination of drinking water.
