本文对２３例不孕患者的２３个周期及对照组１５例２０个周期的宫颈粘液葡萄糖果糖水平进行测定。放免法测定血清促黄体素（ＬＨ）、促卵泡素（ＦＳＨ）、雌二醇（Ｅ２）和孕酮（Ｐ）；阴道Ｂ超监测卵泡发育；宫颈粘液改良Ｉｎｓｌｅｒ评分，尿ＬＨ酶联免疫测定和基础体温测定（ＢＢＴ）综合评价预测和确定排卵日。被研究对象均于围排卵期进行性交后试验（ＰＣＴ）。结果：４３个月经周期均为有排卵周期。不孕组（ＰＣＴ正确组７周期，ＰＣＴ异常组１６周期）宫颈粘液改良Ｉｎｓｌｅｒ评分与对照组无显著差异（Ｐ均＞０．０５）；不孕ＰＣＴ异常组卵泡期、排卵前、排卵后、黄体期宫颈粘液葡萄糖果糖水平均明显低于对照组（Ｐ＜０．０１）。而ＰＣＴ正常组与对照组无明显差异（Ｐ＞０．０５）。结论：宫颈粘液葡萄糖果糖水平低落可影响精子的穿透和存活，是不明原因性不孕的重要因素之一。
In this paper, 23 cycles of 23 infertile patients and control group of 15 cases of 20 cycles of cervical mucosal glucose fructose levels were determined. Serum luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2) and progesterone (P) were determined by radioimmunoassay; vaginal B-ultrasound to monitor follicular development; cervical mucus-modified Insler score and urine LH enzyme-linked immunosorbent assay Thermometry (BBT) Comprehensive Evaluation Predict and determine ovulation days. All the subjects were tested for intercourse during the ovulation period (PCT). Results: All 43 menstrual cycles were ovulation cycles. In infertility group (PCT correct group 7 cycles, PCT abnormal group 16 cycles) cervical mucus improved Insler score and control group no significant difference (P all> 0.05); infertility PCT abnormal group follicular phase, ovulation, ovulation, Luteal phase of cervical mucus glucose and fructose were significantly lower than the control group (P <0.01). There was no significant difference between normal PCT group and control group (P> 0.05). Conclusion: The low fructose and fructose level in cervical mucus can affect the penetration and survival of sperm, which is one of the important factors of unexplained infertility.
