目的：本综述的目的是研究引带在人类胚胎时期睾丸迁移过程中的作用。材料和方法：我们对有关引带在人类胚胎时期睾丸迁移中的作用的文献进行了描述性综述。结果：在睾丸迁移的第一阶段，引带扩大以将睾丸保持在腹股沟附近，并且在第二阶段，引带移动穿过耻骨区域到达阴囊。引带的近端部分附着于睾丸和附睾，在引带远端存在多个附着点是非常罕见的。人类睾丸引带中的肌肉和神经非常少。隐睾患者的引带有更多的纤维组织和较少的胶原蛋白，当患者提交给激素治疗，引带组件alter显着。结论：引带在人类胎儿睾丸迁移过程中提出了显着的结构修改。
Objectives: The objective of this review is to study the role of the gubernaculum in the testicular migration process during the human fetal period.Materials and Methods: We performed a descriptive review of the literature about the role of the gubernaculum in testicular migration during the human fetal period.Results: In the first phase of testicular migration, the gubernaculum enlarges to hold the testis near the groin and in the second phase the gubernaculum migrates across the pubic region to reach the scrotum. The proximal portion of the gubernaculum is attached to the testis and epididymis and the presence of multiple insertions in the distal gubernaculum is extremely rare. The presence of muscle and nerves in the human gubernaculum is very poor. The gubernaculum of patients with cryptorchidism has more fibrous tissue and less collagen and when the patients are submitted to hormonal treatment, the gubernaculum components alter significantly.Conclusions: The gubernaculum presents significant structural modifications during testicular migration in human fetuses.
