Немецкий. Reproductive toxicity refers to the adverse effects of a substance on any aspect of the reproductive cycle, including the impairment of reproductive function, the induction of adverse effects in the embryo, such as growth retardation, malformations, and death. Due to the complexity of the mammalian reproductive cycle, it is impossible to model the whole cycle in a single in vitro system in order to detect chemical effects on mammalian reproduction. However, the cycle can be broken down in its biological components which may be studied individually or in combination. This approach has the advantage that the target tissue/organ of a developmental toxicant can be identified. In specific areas of developmental toxicity, a number of useful and promising in vitro models are already available. The individual tests may be used as building blocks of a tiered testing strategy. So far, research has focused on developing and validating tests covering only a few components of the reproductive cycle, in particular organogenesis of the embryo, reflecting important concerns for teratogenic chemicals. During the last three decades, a number of established models and promising new developments have emerged that will be discussed, e.g. culture of mammalian embryos and embryonic cells and tissues and the use of embryonic stem cells
