目的 :采用阴道B超连续监测卵泡的生长发育 ,子宫内膜的形态及厚度 ,以探讨卵泡的生长、预测排卵、促 超排卵掌握HCG使用时机 ,指导自然受孕或人工助孕 ,以提高妊娠。方法 :应用阴道B超监测 45 0例自然月经周期不孕症患者 (A组 )及 5 90例超 促排卵患者 (B组 )卵泡生长 ,排卵及子宫内膜情况。A组指导同房 ,B组 3 3 8个周期指导同房 ,171个周期行宫腔内人工受精 ,81个周期行试管婴儿。比较两组卵泡生长速度 ,优势卵泡数 ,LUFS发生率 ,妊娠率 ,A级分别为 (1.6± 0 .4)mm d ,1.0个 ,6.4% ,8%。B组分别为 (2 .0± 0 .7)mm d ,(10± 6)个 ,9.5 % ,17.5 % ,上述指标B组明显高于A组 (P <0 .0 1)。结论 :阴道B超在监测卵泡生长及子宫内膜变化、预测排卵 ,适当掌握HCG诱导排卵时机等方面是有价值的。
OBJECTIVE: To monitor the growth and development of follicles, the morphology and thickness of endometrium by vaginal B-ultrasound to explore the growth of ovarian follicles, predict the ovulation, promote ovulation and grasp the timing of HCG use to guide natural pregnancy or artificial pregnancy to improve pregnancy. Methods: 45 cases of infertility with spontaneous menstrual cycle (group A) and 5 90 cases of super-ovulation (group B) were monitored by vaginal ultrasonography for follicular growth, ovulation and endometrium. Group A instructed the same room, Group B 3 38 cycles to guide the same room, 171 cycles intrauterine insemination, 81 cycles of IVF. The follicle growth rate, number of dominant follicles, incidence of LUFS, pregnancy rate and grade A were (1.6 ± 0.4) mm d, 1.0, 6.4% and 8% respectively. Group B were (2.0 ± 0.7) mm d, (10 ± 6), 9.5% and 17.5%, respectively, which were significantly higher in group B than in group A (P <0.01). CONCLUSION: Vaginal B-ultrasound is valuable in monitoring follicular growth and endometrial changes, predicting ovulation and properly grasping the timing of ovulation induced by HCG.
