宫颈松弛为何会导致流产?Why can cervix relax cause miscarriage?

宫颈功能不全是引起晚期习惯性流产的主要原因，也称“宫颈松弛”，顾名思义就是指子宫颈管部的紧张度变松弛无力的状态。

Cervical function is not entirely the main cause of late habitual miscarriage, also known as "cervical relaxation", as the name implies is the tension of the cervix tube become loose and weak.

通常情况下出现宫颈是从妊娠第4～5个月开始容易松弛，当出现这种症状的话就应该及时治疗，避免胎胞落入阴道内，从而导致破水而流产的发生。

Under normal circumstances, the cervical cervix is easy to relax from the 4th to 5th month of pregnancy. When this symptom occurs, it should be treated in time to prevent the fetal cells from falling into the vagina, resulting in the occurrence of miscarriage.

陈凤林教授指出：在孕前干预手术避免了缝扎导致流产的可能性，也不会导致宫颈感染。将“安太环”埋在宫颈内口的肌肉内，有效阻止宫颈内口的扩张。

Preconception intervention avoids the possibility of sutures leading to miscarriage and does not lead to cervical infections, Chenfenglin said. Bury "Antai Ring" in the muscles of the cervix, effectively preventing the expansion of the cervix.
