The endometrium, the inner lining of the uterus, is vital for implantation of the embryo. Histological examination of the endometrium can uncover issues like chronic endometritis, an inflammation of the endometrial lining, which can hinder implantation and result in infertility. Proper endometrial receptivity is also crucial, and histology can be used to evaluate whether the endometrium is adequately prepared for embryo implantation.
