BACKGROUND: Polycystic Ovary Syndrome (PCOS) is a common reproductive disorder that frequently affects fertility. The TyG-BMI (Triglyceride glucose-body mass) index is a newly explored parameter that may be linked to reproductive results in individuals with PCOS. Nevertheless, its connection with outcomes in In Vitro Fertilization (IVF) procedures remains uncertain. METHODS: This study included a total of 966 females who underwent IVF treatments for PCOS. At the baseline, the participants were categorized into four groups according to the quartiles of TyG-BMI measured prior to oocyte retrieval. Subsequently, the study compared the differences in clinical and laboratory outcomes among these four groups. RESULTS: Patients in higher TyG-BMI quartiles exhibited a decreased number of retrieved oocytes, 2PN embryos, and available/high-quality embryos (P < 0.05 for Q1-Q4). Additionally, the multivariable regression analysis revealed that individuals in the top quartile of TyG-BMI had a lower count of accessible embryos (β = -0.224, P = 0.257) and a decreased number of high-quality embryos (β = -0.352, P = 0.028) in comparison to those in the lowest quartile. Nevertheless, there were no notable variances detected in the rates of pregnancy or live births among these quartiles. Furthermore, a linear correlation was noted between the TyG-BMI index and the quantity of accessible embryos (P-non-linear = 0.6, P-overall < 0.001), along with high-quality embryos (P-nonlinear = 0.026, P-overall = 0.006). In contrast, there was no notable linear correlation found between the TyG-BMI index and the available embryo rate (P-nonlinear = 0.60, P-overall = 0.8). CONCLUSIONS: The results of this research emphasize the notable correlation between TyG-BMI and IVF results in females diagnosed with PCOS. The interplay of insulin resistance and disorders of lipid metabolism may indeed play a pivotal role in influencing the assisted reproductive outcomes of patients with PCOS. Considering these findings, TyG-BMI proves to be a valuable indicator for exploring this potential association.
背景：多囊卵巢综合征（PCOS）是一种常见的生殖系统疾病，经常影响生育能力。甘油三酯葡萄糖-体重指数（TyG-BMI）是一个新探索的参数，可能与PCOS患者的生殖结果有关。然而，其与体外受精（IVF）程序结果的关联仍不确定。 方法：本研究共纳入966名接受PCOS-IVF治疗的女性。在基线时，根据取卵前测量的TyG-BMI四分位数将参与者分为四组。随后，研究比较了这四组在临床和实验室结果方面的差异。 结果：TyG-BMI四分位数较高的患者取出的卵母细胞、2PN胚胎以及可用/高质量胚胎数量减少（Q1-Q4，P<0.05）。此外，多变量回归分析显示，与最低四分位数的个体相比，TyG-BMI最高四分位数的个体可获得的胚胎数量较少（β=-0.224，P=0.257），高质量胚胎数量减少（β=-0.352，P=0.028）。然而，这些四分位数之间在妊娠率或活产率方面未检测到显著差异。此外，TyG-BMI指数与可获得的胚胎数量（P-非线性=0.6，P-总体<0.001）以及高质量胚胎数量（P-非线性=0.026，P-总体=0.006）之间存在线性相关性。相比之下，TyG-BMI指数与可用胚胎率之间未发现显著的线性相关性（P-非线性=0.60，P-总体=0.8）。 结论：本研究结果强调了TyG-BMI与诊断为PCOS的女性IVF结果之间的显著相关性。胰岛素抵抗和脂质代谢紊乱的相互作用可能确实在影响PCOS患者的辅助生殖结果中起关键作用。考虑到这些发现，TyG-BMI被证明是探索这种潜在关联的一个有价值的指标。
