Just after ovulation, oocyte fertilization by spermatozoa can take place in the fallopian tubes.   <\/p><p> <\/p><p>During the following days, the embryo will develop by gradually migrating from the fallopian tubes to the uterus, site of the embryonic implantation. At the same time, the endometrium matures and when the progesterone reaches its peak of concentration, <b>it becomes receptive to the embryonic implantation<\/b>.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8bef584 elementor-widget elementor-widget-image\" data-id=\"8bef584\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"801\" height=\"751\" src=\"https:\/\/www.gainlab.fr\/wp-content\/uploads\/2022\/07\/GAIN-infographie-Endome\u0300tre-EN.png\" class=\"attachment-full size-full wp-image-2108\" alt=\"\" srcset=\"https:\/\/www.gainlab.fr\/wp-content\/uploads\/2022\/07\/GAIN-infographie-Endome\u0300tre-EN.png 801w, https:\/\/www.gainlab.fr\/wp-content\/uploads\/2022\/07\/GAIN-infographie-Endome\u0300tre-EN-300x281.png 300w, https:\/\/www.gainlab.fr\/wp-content\/uploads\/2022\/07\/GAIN-infographie-Endome\u0300tre-EN-768x720.png 768w\" sizes=\"(max-width: 801px) 100vw, 801px\" style=\"width:100%;height:93.76%;max-width:801px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6a52991 elementor-widget elementor-widget-text-editor\" data-id=\"6a52991\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-size: 1rem;\">The endometrial receptivity window describes the timing of the cycle during which the endometrium is ready to host an embryo.
