Abstract Prostate cancer (PCa) is among the most frequent cancers worldwide. Nowadays, several therapeutic strategies are available for PCa treatment, namely chemotherapy, immunotherapy, radiotherapy, and hormonal therapy. Despite existing therapeutic approaches, in vitro and in vivo models are essential to better understand cancer development and search for more effective therapies, with a positive impact in cancer patient survival and quality of life. Among several models available, the rat model is the one most frequently used, since it shares anatomical, physiological, pathological, and behavioral features with humans. Animal models can be classified as: spontaneous, chemically-induced; hormonally-induced; implantation of cancer cell lines obtained from humans or from the same species, in the place of disease development or in a different place; and genetically-modified models. The chemically-induced models are among the most frequently used for PCa research. This manuscript provides a comprehensive overview of PCa models, presenting their application, advantages, and disadvantages, and their importance for the development of current therapies for prostate cancer.
