BackgroundPolycystic ovary syndrome is the most extensive type of reproductive endocrine disease in department of gynecology.AimsThis observation aimed to investigate the predictive value of anti-endometrial antibody (EMAb) level in polycystic ovary syndrome (PCOS) complicated with infertility.MethodsA total of 87 PCOS patients with infertility were selected as the research objects, and 86 healthy women who underwent pre-pregnancy physical examination were volunteers of the control group. The serum samples of the two groups were collected, and the serum EMAb level was detected by enzyme-linked immunosorbent assay (ELISA), and Pearson correlation was used to analyze the correlation between serum EMAb and sex hormone levels. ROC was drawn to analyze the predictive value of EMAb in PCOS complicated with infertility. Logistic regression was calculated to predict the risks of PCOS with infertility.ResultsThe levels of EMAb were significantly higher in infertile patients with PCOS. Serum EMAb was positively correlated with BMI, luteinizing hormone (LH), and testosterone and negatively correlated with estradiol and progesterone in PCOS complicated with infertility group. The AUC of serum EMAb in differentiating PCOS with infertility was 0.928. Serum EMAb, LH, testosterone, and estradiol were independent risks for infertility in PCOS.ConclusionsSerum EMAb level in PCOS patients with infertility was significantly increased, and it was significantly correlated with sex hormone levels. Serum EMAb level could be used as a predictor of infertile patients with PCOS.© 2022. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.
