Transverse parorchidium is characterized by the presence of two testes in the same bursa, and may be associated with persistent Müllerian vestige in the spermatic cord of the normally situated testis. Persistence of Müllerian vestige is related to inadequate production of anti-Müllerian hormone by the embryonal testis. Transverse parorchidium is caused by the emergence of both deferent ducts into the Müllerian vestige. Diagnosis is evoked by the presence of an empty bursa associated with an abnormally hard spermatic cord contralaterally. This syndrome should be known of surgeons, as ablation of the Müllerian vestige consecutive to surgical management of a hernia or ectopic testis may lead to the sectioning of the deferent ducts.
睾丸横过异位的特征是在同一个囊内存在两个睾丸，并且可能与正常位置睾丸的精索中残留的苗勒管遗迹有关。苗勒管遗迹的残留与胚胎睾丸抗苗勒管激素分泌不足有关。睾丸横过异位是由于双侧输精管进入苗勒管遗迹所致。诊断依据是对侧存在与异常坚硬的精索相关的空虚囊。外科医生应该了解这种综合征，因为在疝或隐睾的手术治疗后切除苗勒管遗迹可能会导致输精管切断。
