Le Le mom in the fourth consecutive pregnancy after the birth of music is about six months of pregnancy miscarriage, in the hospital to see is cervical relaxation, but also did a ring to fail to retain the baby, so how is cervical relaxation caused?

陈凤林教授指出：宫颈松弛是怎么导致的这个并不难识别，像乐乐妈这样的情况若是第一胎很好，很明显是分娩时的产伤导致的，如果从未生育过也未做过一些宫内手术，那就考虑是先天性的了，不管宫颈松弛是怎么导致的，治疗方案都是一致的，进行宫颈内口宫颈埋箍技术，孕前就可以，孕后月份越小越好，做了以后怀孕就有保障了，不会再流产。

Professor Chenfenglin pointed out: It is not difficult to recognize how cervical relaxation is caused. If the first child is good, it is obviously caused by childbirth injuries. If it has never been born, it has not undergone some intrauterine surgery. It is considered congenital, no matter how the cervical relaxation is caused, the treatment plan is the same, the cervical cervix implantation technology, can be before conception, the smaller the month after pregnancy, the better. After the pregnancy is guaranteed, there will be no miscarriage.
