In a prospective study of 166 male breech babies, 13 babies delivered by cesarean section did not show damage to the genital area. Of the 134 delivered vaginally, 19 showed injury to buttocks, scrotum, or testis. Ten babies (6.5%) showed damage to testis. On follow-up of three months to four years, the testis became normal to palpation in only 3 babies. In 1 baby, the testis became impalpable, leaving an empty scrotum. The testicular injury is more likely to occur in babies with a birth weight of greater than or equal to 2,500 g and born to primipara. The breech babies delivered vaginally should be examined and followed up for possible damage to testis. To avoid costly investigation and risky exploration, a history of breech delivery should be obtained in all cases presenting as anorchia, undescended testis, delayed sexual maturation, or male infertility.
在一项对166例男性臀位婴儿的前瞻性研究中，13例剖宫产出生的婴儿生殖器区域未显示损伤。在134例经阴道分娩的婴儿中，19例出现臀部、阴囊或睾丸损伤。10例婴儿（6.5%）睾丸受损。在3个月至4年的随访中，只有3例婴儿的睾丸触诊恢复正常。1例婴儿的睾丸无法触及，阴囊空虚。睾丸损伤更可能发生在出生体重≥2500g的婴儿以及初产妇所生的婴儿中。经阴道分娩的臀位婴儿应接受检查并随访，以排查睾丸可能受到的损伤。为避免昂贵的检查和有风险的探查，对于所有表现为无睾、隐睾、性成熟延迟或男性不育的病例，均应了解其臀位分娩史。
