Progress in Establishment and Application of Laboratory Animal Models Related to Development of Male Infertility Drugs

As the incidence of male infertility has been increasing during recent years, it is urgent to reveal the pathogenesis of male infertility, as well as to develop the new drugs for treatment of male infertility, in order to solve the declining birth rate and aging problems. The construction and application of male infertile animal models is critical for drug development, which plays an important role in accurately evaluating the efficacy and mechanism of infertility treatment. A suitable infertility model not only can reduce the repeated drug efficacy evaluations, reduce animal usage and the cost of new drug development, but also has important reference value for subsequent clinical trial research. Male infertility laboratory animal models can be constructed through chemical, physical, endocrine, environmental estrogen, gene modification, and immune methods. This article mainly introduces the existing male infertility animal models available for drug development, and briefly introduces the application progress
