我只有一个输卵管。我是否有可能怀孕?
回答 Yvonne Butler Tobah, M.D.
是的。输卵管是卵子穿过卵巢到达子宫的一对管道。每月的月经周期期间,其中一个卵巢会释放一个卵子。该过程称为排卵。然后卵子沿着其中一个输卵管向下移动。卵子可能会也可能不会被输卵管中的精子受精。如果卵子受精,需要附着在子宫壁上才能开始妊娠。
如果您曾因感染、肿瘤或既往异位妊娠接受过盆腔手术,则可能只有一根输卵管。异位妊娠中的受精卵附着在子宫外而无法存活。此外,只有一个输卵管可能是先天性的。但倘若符合以下条件,您仍然可以只通过一根输卵管怀孕:
- 您至少有一个功能正常的卵巢。
- 您每月有一次月经周期。
- 您剩下的输卵管非常健康。
如果您在尝试怀孕至少 6 个月后无法怀孕,请咨询妇科医生或生育能力专科医生(称为生殖内分泌科医生)。如果您有影响一个或两个输卵管的已知健康问题,您也可以去看医疗护理专业人员。医疗护理专业人员可能会与您讨论可增加怀孕几率的治疗方法。这些治疗被称为辅助生殖技术,包括体外受精,也称为 IVF。
