Abstract

Objective: To determine whether women with hydrosalpinx would have diminished endometrial HOXA10 expression and whether salpingectomy would reverse HOXA10 suppression. The homeobox gene HOXA10 is a transcription factor that is necessary for embryo implantation; its expression in human endometrium correlates with receptivity and implantation. Increased endometrial HOXA10 expression may be one mechanism by which salpingectomy results in increased implantation rates in IVF. Design: Prospective clinical trial. Setting: Academic medical center. Patient(s): Women with unilateral or bilateral hydrosalpinx. Intervention(s): Expression of HOXA10 was examined prospectively during the midluteal phase in endometrium obtained from infertile women (n = 9) with hydrosalpinges before and after salpingectomy, as well as from fertile controls (n = 6). Quantitative HOXA10 mRNA expression was determined by real-time reverse-transcription polymerase chain reaction, and HOXA10 protein expression was determined by immunohistochemistry. Main Outcome Measure(s): Expression of HOXA10 mRNA and protein. Result(s): Expression of HOXA10 mRNA was significantly lower in infertile women with hydrosalpinges, compared with the case of fertile controls. Salpingectomy resulted in a statistically significant, 15-fold increase in endometrial HOXA10 expression. Immunohistochemical analysis confirmed the quantitative real-time reverse-transcription polymerase chain reaction findings. Increased HOXA10 expression was evident in both glandular epithelial cells and endometrial stroma. Conclusion(s): HOXA10 is necessary for implantation. Here, we demonstrate decreased HOXA10 expression in response to hydrosalpinx fluid as a potential molecular mechanism for diminished implantation rates. Salpingectomy restores endometrial HOXA10 expression. This may be one mechanism by which salpingectomy results in augmented implantation rates in IVF.
