Monoclonal antibody D9B1 has been shown to bind to a carbohydrate epitope associated with high molecular weight secretory sialoglycoprotein(s) of human endometrium. The authors demonstrate that, in a group of 28 patients diagnosed on the basis of histopathologic assessment as exhibiting luteal phase defect, 68% reveal significantly diminished expression of the epitope. Furthermore, histologic assessment of the secretory activity in single glands does not correlate simply with the level of expression of the epitope. Of specimens from patients complaining of infertility, 92% showed defective production of the D9B1 epitope. Thus, D9B1 immunohistochemistry provides a new molecular criterion for defective endometrial function.
