An endometrial polyp is most commonly a benign, localized proliferation of the glands and the endometrial stroma, covered with epithelium and protruding above the level of the mucosa. These polyps are most often diagnosed during investigation into the causes of irregular menstrual bleeding or infertility. It is produced in the highest concentration during the secretory phase of the endometrial cycle. The level of glycodelin reaches its peak 12 days after ovulation. The aim of this paper was to determine the changes in the immunohistochemical expression of glycodelin at the level of the endometrium and in the tissue of the polyp, before and after hysteroscopic polypectomy, in infertile female patients with an endometrial polyp, and in the endometrial tissue of female patients without an endometrial polyp. The study included 82 infertile female patients. The infertile patients were divided into two groups. The first was the experimental group which included 56 infertile female patients who had an endometrial polyp. The second group was the control group, composed of 26 infertile female patients who did not have an endometrial polyp. The results obtained primarily indicate the existence of changes in the immunohistochemical expression of the cytokine glycodelin in the female patients from both the experimental and the control group, not only prior to but also after hysteroscopy. A larger number of patients who have an endometrial polyp show a lack of glycodelin expression, more pronouncedly so in the bioptate of the endometrium than in the endometrial polyp.
