The invention relates to a construction method of an experimental autoimmune
prostatitis rat model. The construction method comprises the following steps: S1, preparing a
prostate specific
antigen mixture; s2, selecting male SD rats as laboratory rats, and dividing the laboratory rats into a normal
saline control group, a low-
dose model group and a high-
dose model group; s3, continuously injecting for 7 days, allowing the normal
saline control group to accept injection of 0.2 ml of normal
saline every day, allowing the low-
dose model group to accept injection of 0.1 ml of
prostate specific
antigen mixture every day, and allowing the high-dose model group to accept injection of 0.2 ml of
prostate specific
antigen mixture every day; and S4, continuously feeding all groups of experimental mice to the 28th day, inducing the experimental mice in the low-dose model group and the high-dose model group by the
prostate specific antigen mixture to cause experimental autoimmune
prostatitis, and obtaining the experimental autoimmune
prostatitis rat model. The use of animals can be reduced, the cost is reduced, and the modeling efficiency and stability can be improved.
