在体外受精-胚胎移植过程中胚胎移植技巧相当重要,备受关注。为提高此项技巧需避免胚胎移植过程对胚胎着床的不利因素,其方法有:试验性胚胎移植、超声测定正确估计子宫腔,使用柔软移植管、轻柔操作、尽量避免使用宫颈钳减少对子宫刺激引起收缩,去除宫颈黏液,在尽量减少对子宫内膜损伤的情况下保证移植管通过宫颈内口,将胚胎轻柔地送入子宫腔内,从而最终提高临床妊娠率。 In vitro fertilization - Embryo transfer embryo transfer technology is very important, much attention. In order to improve this technique, unfavorable factors of embryo implantation should be avoided. The methods include: experimental embryo transfer, ultrasound to correctly estimate uterine cavity, soft transplanting tube, gentle operation, avoid using cervical forceps and reduce uterus Stimulation caused contraction, removal of cervical mucus, in the case of minimizing damage to the endometrium to ensure that the graft through the mouth of the cervix, the embryo gently into the uterine cavity, and ultimately improve the clinical pregnancy rate.
