马来西亚三代试管婴儿胚胎移植后有哪些流程

做马来西亚三代试管婴儿最激动人心的便是移植了,移植的时候,每个人多多少少都会有点紧张和期待,甚至有不少人在移植前一晚,紧张的睡不着觉。移植后一般七-17天就可抽血验孕了,那在这7-14天时间里我们的宝宝在做什么呢?

马来西亚试管婴儿胚胎着床

着床用通俗的话来讲,就是“种子”宝宝在妈妈的子宫里找到合适的“土壤”扎根了,而这整个过程并不是一瞬间能完成的,而是需要一定的时间,逐步进行。

移植过后,并不会马上知道胚胎是否着床,医生会让患者们7-14天左右的时间再进行验孕,在这段看似漫长的时间里,胚胎也在争分夺秒的努力的要在妈妈子宫里落地生根。

1. 四处游动

医生把受精卵放置进入胚胎子宫后,胚胎处于游离状态,会在子宫,输卵管内四处游动,如果子宫温暖,环境适宜,受精卵就会在子宫内着床,如果妈妈子宫较为寒冷,那受精卵宝宝是待不住的,子宫待不了,受精卵很可能会往宫外跑,造成宫外孕。

2.试管婴儿胚胎着床

在第7-10天内囊胚细胞会长出一个小尾巴样的钻头,会在妈妈的子宫壁上找到一个合适又舒服的位置,然后钻进子宫壁。这时,可能有部分人出现少量出血,不必紧张,一般是着床期出血。

3.继续分裂

在11天后,胚胎已经整个陷入子宫内并且继续分裂着,越来越多的细胞开始分泌HCG,并且会随着时间的增加而分泌的越多。所以一般建议移植后12-14天抽血验孕。

4.开始发芽

受精卵产生一种蛋白质分解酶,溶解和它接触的子宫内膜,受精卵将自己慢慢埋入到子宫内膜的功能层中,“种子植入后开始发芽”过程开始。


5.扎根生长

受精卵埋入子宫内膜,被完全覆盖,植入过程完成。受精卵扎根迅速生长,合体滋养细胞发育,伸出许多呈均匀绒毛状的细胞突起,侵入子宫内膜的肌层和血管中,而滋养细胞分泌的HCG会随着受精卵的发育而越来越多。

6.早期胎盘形成

在受精卵植入的地方,形成早期的胎盘组织,来自母体循环系统的血液开始在胎盘内循环,和胚胎进行物质交换。

7.验孕成功

此时母体血液中和尿液中的HCG已经升高到了一定水平,从而用早孕试纸也大多可以看到双杠。
