摘要
Introduction: The relationship between basal luteinizing hormone (LH) and reproductive outcomes in women with polycystic ovary syndrome (PCOS) undergoing intrauterine insemination (IUI) has remained largely unknown, warranting further investigations. Accordingly, this study aimed to investigate the possible association of basal LH with reproductive outcomes in women with PCOS women undergoing IUI to gain a better understanding of this topic. Material and methods: Data from 533 cycles of controlled ovarian stimulation (COS) and IUI treatments from PCOS women were retrospectively analyzed. Statistical methods, including univariate analysis, receiver operating characteristic (ROC) curve, quartile division, and Spearman rank correlation analysis, were utilized. Results: Basal LH resulted as the most significant contributor to pregnancy (P < 0.001). ROC analysis revealed that the predictive power of basal LH on pregnancy was stronger compared to other factors (areas under the curve 0.614, 95% CI 0.558-0.670, P = 0.000). Analysis based on quartile division unveiled a stair-shaped relation of basal LH with pregnancy or live birth as well as a positive linear relation between basal LH and early miscarriage (all P trend<0.05). Basal LH of 11.69 mIU/ml was the point above which early miscarriage grew significantly while pregnancies and live births ceased to increase. Moreover, basal LH was positively correlated with antral follicle count (AFC), number of mature follicles on the trigger day, clinical pregnancy, live birth, and multiple pregnancies (all P < 0.05). The number of mature follicles on the trigger day was positively correlated with clinical pregnancy, early miscarriage, and multiple pregnancies (all P < 0.05). AFC was positively correlated with clinical pregnancy (P < 0.05). Conclusion: Hypersecretion of basal LH was associated with an increased risk of pregnancy loss among PCOS women undergoing COS and IUI. Basal LH may have predictive value on pregnancy achievement in women with PCOS undergoing COS and IUI.
