Abstract
Endometriosis causes infertility and the alterations in endometrial receptivity. Pinopodia in eutopic endometrial epithelium may have significant implications in the endometriosis-associated infertility. The aim of this study is to ascertain whether the surgical interventions to remove endometrioid ovarian cysts (EOCs) can improve endometrial receptivity. The study included 172 patients of reproductive age with EOC, who underwent laparoscopic cystectomy. Aspiration endometrial biopsy was performed at 6 and 12 months after the surgery during the proliferation and secretion phases. Histopathology analysis included H&E staining and IHC. Morphometric studies were performed on endometrial biopsies collected during the proliferation phase of 28 patients, and the secretion phase of 12 patients. The expression of IHC markers for estrogen receptors (ER) and progesterone receptors (PR) and the percentage of cells containing pinopodia were determined. A significant increase in the ER and PR expression was observed in the epithelium during the "middle stage, proliferation phase" and in the stroma and glands during "middle stage, secretion phase". A delay in endometrial secretory transformation and statistically significant decrease in the number of pinopodia was observed on the apical surface of the cells. These structural and functional alterations were observed both at 6 and 12 months after cystectomy. The endometriosis-associated infertility after surgical intervention of EOC could be due to the extensive expression of ER and PR during the proliferation and secretion phases, as well as the delayed secretory transformation and impaired formation of pinopodia in the eutopic endometrium in the patients at 6 and 12 months after surgery.
