Abstract:
Objective:To analyse the influence of endometrial polyps (EPs) treatment on the frozen-thawed embryo transfer (FET) pregnancy outcome.Methods:Using a retrospective case-control study, the data of patients were collected who received in vitro fertilization (IVF) and hysteroscopy in the Reproductive Medicine Center of Children's Hospital of Shanxi and Women Health Center of Shanxi from June 2021 to December 2022. Patients undergoing hysteroscopy were studied. According to the diagnosis results of hysteroscopy and pathology, they were selected as the EPs group or the non-endometrial polyps (NEPs) group. Then analysis of EPs risk factors was made, and the pregnancy outcome of FET after the EPs treatment was compared. Results:A total of 3 413 patients underwent hysteroscopy in this study. The EPs group included 444 patients and the NEPs group included 1 501 patients respectively. The prevalence of EPs was 13.01% (444/3 413). There were significant differences between EPs group and NEPs group in gravidity, parity, spontaneous abortion times, induced abortions times, basal follicle-stimulating hormone (bFSH), basal luteinizing hormone (bLH), infertility duration, infertility types, the prevalence of chronic endometritis, the history of polyps removal and endometriosis (all P<0.05). Multivariate logistic regression analysis of risk factors associated with EPs showed that infertility duration ( OR=1.068, 95% CI: 1.029-1.109, P<0.001), chronic endometritis ( OR=1.925, 95% CI: 1.481-2.502, P<0.001), primary infertility ( OR=1.803, 95% CI: 1.408-2.308, P<0.001), history of polyps removal ( OR=9.424, 95% CI: 5.586-15.897, P<0.001), endometriosis ( OR=2.432, 95% CI: 1.344-4.401, P=0.003) were independent risk factors for EPs, and bLH ( OR=0.954, 95% CI: 0.916-0.993, P=0.022) was an independent protective factor for EPs. Compared with NEPs transplantation group, there were no significant differences in clinical pregnancy rate, on-going pregnancy rate and none implantation rate in the EPs treatment transplantation group (all P>0.05). Conclusion:Infertility duration, chronic endometritis, primary infertility, history of polyps removal, endometriosis were independent risk factors, and bLH was an independent protective factor. Patients in EPs treatment transplantation group could achieve the similar pregnancy outcome as NEPs transplantation group.
