[Male infertility - related gene knockout mouse models].

The pathogenesis of male infertility is rather complicated. The establishment of animal models, especially mouse models, of male infertility, provides a model basis for the studies of the roles and molecular mechanisms of infertility-related genes. Currently there are mainly three types of mouse models for biomedical researches, namely, the mouse model made by the knockout, knock-in or gene capture method, transgenic mouse model, and chemically induced point mutant mouse model. This review summarizes male infertility - related gene knockout mouse models, aiming to find a suitable animal model for studying the pathogenesis of male infertility.
