A case of pubopenile testis and a case of perineal ectopic testis are presented. The mechanism of descensus is largely positive, possibly facilitated by raised intra-abdominal pressure. The testis is usually guided by the gubernaculum and ectopia results from gubernacular failure. The ectopic testis is relatively rare but is easily recognized and treated by orchiopexy.
本文报告1例耻骨阴茎部睾丸及1例会阴部异位睾丸病例。睾丸下降机制大多正常，可能是由于腹内压升高所致。睾丸通常由睾丸引带引导下降，异位是由于睾丸引带发育不全引起。异位睾丸相对少见，但易于识别，可通过睾丸固定术进行治疗。
