The entering of MAMPs to testis leads to testicular inflammation and BTB damage. MAMPs, such LPS, enter the blood circulation through intestinal barrier and cause systemic endotoxin. When LPS arrive at the testes via the testicular artery, it activates toll-like receptor (TLR) cause orchitis and damage to the BTB.
