“…In addition to the observed testicular and/or scrotal swelling [ 163 – 165 , 167 , 168 ], the diagnosis often relies on ultrasound examination and sometimes reveals a testicular mass suspicious for malignancy, which generally leads to orchidectomy [ 165 – 167 ], even if some work succeeded in saving the patient’s testicle using antibiotics [ 163 ]. Testicular infection can give rise to typical gummatous orchitis [ 165 , 167 – 170 ], that is a central necrotic area surrounded by inflammatory cells (mainly lymphocytes and plasma cells) or to atypical lesions devoid of necrosis [ 164 , 166 ]. Other testicular damage were described, like atrophy or destruction of the seminiferous tubules [ 164 , 168 , 170 ], destruction of parenchyma [ 168 ] or obliterative vasculitis in some blood vessels [ 164 ], making syphilis a very likely cause of male infertiltiy, even if no infertility cases directly resulting from T. pallidum infection have been reported.…”
