有网友问：医生宫颈机能不全宫颈松和流产有没有关系?Some Netizen asks: doctor cervix function is not complete cervix loose and Miscarriage have relation?

陈凤林教授指出：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。

Professor Chenfenglin pointed out: Cervical function is not entirely the main cause of late habitual Miscarriage, also known as "cervical relaxation", as its name implies, refers to the tension of the cervical canal become loose and weak.

通常情况下出现这样症状的一般是从妊娠第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, such symptoms are generally easy to relax from the 4th to 5th month of pregnancy. When such symptoms occur, they should be treated in a timely manner to prevent the fetal cells from falling into the vagina, resulting in the occurrence of Miscarriage.
