Endometrial receptivity<\/strong> is the structural and functional state of the uterine mucosa (endometrium) at the time of implantation. This state depends on the stage of a woman’s menstrual cycle.<\/p>\n\n\n\n

Usually, during a natural cycle, the embryo can implant in the endometrium:<\/p>\n\n\n\n

    \n
  1. 7 days after the peak luteinizing hormone concentration in the blood (LH+7);<\/li>\n\n\n\n
  2. 5 days after progesterone administration (Pr+5), in a cycle using hormone replacement therapy.<\/li>\n<\/ol>\n<\/div>\n\n\n\n
    \n

    According to modern concepts, endometrial receptivity is an important factor for successful embryo implantation during ART(assisted reproductive technology) cycle, along with its morphological and chromosomal status.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

    The implantation window<\/strong> is the time period most favorable for embryo implantation.<\/p>\n\n\n\n

    On average, the implantation window lasts 48 hours; however, in some cases, its beginning and end may be shifted in time, leading to unsuccessful, sometimes repeated, attempts to conceive.<\/p>\n\n\n\n
