子宫内膜容受性是胚胎着床、成功妊娠的必要条件。对子宫内膜容受性进行评估是辅助生育技术中重要的一环。其评价指标有很多,目前应用较为广泛的包括内膜活检、超声检查、内分泌检查和内膜分泌物分析等。内膜活检法因其创伤性使临床应用受到限制;超声虽能简便有效地预测内膜容受性,但存在很大的争议;激素及分子生物学指标从分子生物学方面阐明了影响内膜容受性的重要因素,具有其独特的临床应用价值;内膜分泌物分析在评价子宫内膜容受性方面,具有无创性、信息量大等优势,近年来正在成为生殖领域研究的热点。 Endometriosis is embryo implantation, a necessary condition for successful pregnancy. Assessment of endometrial receptivity is an important part of assisted reproductive technology. The evaluation index there are many, at present more widely used, including endometrial biopsy, ultrasound, endocrine examination and endometrial secretion analysis. Endometrial biopsy because of its traumatic clinical application is limited; although ultrasound can easily and effectively predict endometrial receptivity, but there is much controversy; hormones and molecular biology indicators elucidated from the molecular biology aspects of the intima Tolerance of the important factors, has its unique clinical value; endometrial secretions in the evaluation of endometrial receptivity, with non-invasive, large amount of information and other advantages, in recent years is becoming a hot research field of reproduction.
