Relationships between follicular fluid levels of IL-6 with ovarian response and clinical pregnancy were evaluated in IVF-ET cycles.
Follicular fluid was collected from ovarian follicles ≥ 14 mm, pooled for each patient, and IL-6 levels were assessed using ELISA (n = 68). Relationships between IL-6 levels and IVF cycle parameters were assessed using nonparametric tests, and between IL-6 levels and clinical pregnancy using multivariable logistic regression analyses.
Significant positive correlations were observed between IL-6 with age (p = 0.035), and IL-6 with estradiol on the day of hCG (p = 0.011). On adjusted analyses, IVF cycles in patients with IL-6 levels <4.0 pg/ml (median value for the group) demonstrated an almost 4-fold increase in likelihood for clinical pregnancy (p = 0.045).
Lower follicular fluid IL-6 levels in IVF patients are associated with increased likelihood of clinical pregnancy. We hypothesize that endometrial receptivity is a likely target for any deleterious influences of elevated IL-6 levels.
评估 IVF-ET 周期中卵泡液中白细胞介素-6(IL-6)水平与卵巢反应和临床妊娠的关系。
收集≥14mm 的卵巢卵泡中的卵泡液,对每个患者进行汇集,并使用 ELISA 法评估 IL-6 水平(n=68)。使用非参数检验评估 IL-6 水平与 IVF 周期参数之间的关系,使用多变量逻辑回归分析评估 IL-6 水平与临床妊娠之间的关系。
IL-6 与年龄呈显著正相关(p=0.035),与 hCG 日的雌二醇呈显著正相关(p=0.011)。在调整分析中,IL-6 水平<4.0pg/ml(该组的中位数)的 IVF 周期患者临床妊娠的可能性几乎增加了 4 倍(p=0.045)。
IVF 患者卵泡液中较低的 IL-6 水平与临床妊娠的可能性增加相关。我们假设子宫内膜容受性是升高的 IL-6 水平产生任何有害影响的可能靶点。
