经阴道超声评价不孕症患者子宫内膜容受性的研究进展

随着辅助生殖技术的发展，应用体外受精一胚胎移值（IVF-EI）对小孕症患者的诊治取得了很大的进展，胚胎质量和子宫内膜容受性是决定不孕症患着治疗成败的两个关键因素，用于评价子宫内膜的方法很多，如免疫组化法、内膜活检等，而经阴道超声以其简便、无创、可重复性等优点成为不孕症诊治中评估子宫内膜容受性的常规方法。

The study of endometrium receptivity in infertility by transvaginal ultrasonography

With the development of assisted reproductive technology, more and more progresses have been made in vitro fertilization and embryo transfer( IVF - ET). Embryo quality and endometrium receptivity are the two most important factors for the outcome in IVF - ET. Various types of measurements were applicated to evaluate the endometrium receptivity, such as immunohistochemical technique, endometrial biopsy, et al. At present, transvaginal ultrasonography has become a routine examination, in terms of its safety, noninvasion and repeatability, et al.
