Objective: To study the modeling characteristics of primary dysmenorrhea models in animals and to provide references for the standardization of the primary dysmenorrhea animal models. Method: The research articles on animal models of primary dysmenorrhea were retrieved to establish a database. The types of experimental animals,modeling methods,modeling cycle,drug dosage,drug injection methods,high-frequency detection indicators,positive drug types,etc.,were summarized and analyzed. Result:A total of 171 research articles that met the...
