【摘要】：目的探讨卵巢正常反应不孕症患者体外受精/卵胞质内单精子显微注射(IVF/ICSI)促排卵时应用口服避孕药(OC)长方案和黄体中期长方案的促排卵效果及临床结局。方法选择接受长方案IVF/ICSI助孕的卵巢正常反应患者共4 677个周期;根据年龄分为≤35岁组和35岁组,不方便超声监测排卵或自然周期超声监测卵泡不破裂的患者共2 762个周期,应用OC长方案(OC组);自然周期超声监测正常排卵的患者共1 915个周期,应用黄体中期长方案(黄体中期组);常规行IVF/ICSI,比较上述不同年龄人群2种促排卵方案的临床和实验室相关指标。结果 (1)OC组促性腺激素(Gn)启动日雌二醇(E2)[≤35岁组:(24.63±10.62)ng/L,35岁组:(24.24±10.40)ng/L]和促黄体生成素(LH)水平[≤35岁组:(0.92±0.59)IU/L,35岁组:(0.82±0.66)IU/L]均明显低于黄体中期组[≤35岁组:(25.89±12.80)ng/L,35岁组:(25.71±10.93)ng/L;≤35岁组:(1.37±0.59)IU/L,35岁组:(1.01±0.70)IU/L](P0.05);(2)OC组人绒毛膜促性腺激素(h CG)注射日E2水平[≤35岁组:(4 143.8±2 769.9)ng/L,35岁组:(3 597.5±2 160.4)ng/L]和因卵巢过度刺激综合征(OHSS)行全胚冷冻率(≤35岁组:9.1%,35岁组:10.2%)均明显高于黄体中期组[≤35岁组:(3 850.8±2 092.4)ng/L,35岁组:(3 213.4±1 804.5)ng/L;≤35岁组:4.9%,35岁组:5.9%](P0.05),但h CG注射日的内膜厚度[≤35岁组:(10.75±2.25)mm,35岁组:(10.47±2.38)mm]却明显小于后者[≤35岁组:(11.62±2.43)mm,35岁组:(11.09±2.68)mm](P0.05);(3)在年龄35岁的OC组Gn总用量[(3 775.4±1 200.0)IU]和使用时间[(13.5±2.2)d]明显高于黄体中期组[(3 516.9±1 156.1)IU,(12.4±2.2)d](P0.05);(4)2种降调节方案患者的获卵数、ICSI成熟卵数、双原核(2PN)受精率、平均移植胚胎数、优质胚胎率和早期流产率均无明显差异(P0.05),但OC组的着床率(≤35岁组:41.4%,35岁组:25.5%)和临床妊娠率(≤35岁组:55.7%,35岁组:37.5%)明显小于黄体中期组(≤35岁组:46.7%,35岁组:31.4%;≤35岁组:65.6%,35岁组:46.9%)(P0.05)。结论 (1)OC长方案可加深垂体抑制,尤其是35岁的高龄患者需增加Gn用量才能达到与黄体中期长方案相似的促排卵效果;(2)OC长方案可能通过影响子宫内膜厚度及容受性而降低着床率和临床妊娠率;(3)OC长方案使h CG注射日E2水平更高,易诱发OHSS的发生。故对卵巢功能正常的不孕患者,IVF/ICSI助孕时尽量选择黄体中期长方案。
[Abstract]:Objective to investigate the effect and clinical outcome of oral contraceptive regimen (OCC) and midluteal length regimen on ovulation induction by IVF / ICSI in infertile women with normal ovarian response in vitro fertilization / intracytoplasmic sperm injection (IVF / ICSI). Methods the results of IVF / ICSI IVF / ICSI IVF / ICSI IVF / ICSI in ovulation promotion were studied. There were 4 677 cycles in normal ovarian response patients who received long term IVF/ICSI to assist pregnancy. There were 2 762 cycles in patients who were divided into 鈮，
