This brief review will examine the investigation of the endometrial cavity before embryo transfer using various techniques, including hysteroscopy, endometrial biopsy using immunohistochemistry and molecular microarray, and ultrasound imaging. All these investigative tools are presently subject to controversy and require large prospective controlled trials for validation. During embryo transfer, the occurrence of a retained embryo does not appear to have a negative impact on pregnancy outcome, and finally, consistent data indicate that physical activity immediately after embryo transfer has no impact on pregnancy outcome.
这篇简要回顾将检查胚胎移植前使用各种技术检查子宫内膜腔，包括宫腔镜检查、使用免疫组织化学和分子微阵列的子宫内膜活检，以及超声成像。所有这些研究工具目前都存在争议，需要进行大型前瞻性对照试验来验证。在胚胎移植过程中，胚胎残留的发生似乎不会对妊娠结局产生负面影响，最后，一致的数据表明胚胎移植后立即进行体育活动不会对妊娠结局产生影响。
