摘要 目的:探讨低剂量克罗米芬(CC)用于女性促排卵治疗的优势。方法:收集行促排卵治疗的女性188例,随机分为常规量组(CC 50mg/d)和低剂量组(CC 25mg/d),患者于月经周期第5天开始服药,第10天检测血清FSH、LH、E2值,经阴道B超监测卵泡发育和子宫内膜情况。比较两组HCG日Gn使用剂量、Gn使用天数、卵泡大小、排卵数及取消周期数。结果:患者的BMI均较高,属于超重。两组患者的年龄、BMI、基础内分泌(FSH、LH、E2、T)水平比较,差异均无统计学意义(P>0.05)。与基础状态相比,用药5天后低剂量组的FSH升高不明显(P=0.69),常规量组FSH明显升高(P=0.000);两组LH及E2水平较基础状态均明显升高(P=0.000),但两组无明显差异(P>0.05)。用药5天及HCG日时,低剂量组的子宫内膜厚度均明显高于常规量组(P=0.000);用药5天后低剂量组的优势卵泡直径明显大于常规量组(P=0.000),但HCG日两组的成熟卵泡直径无明显差异(P=0.56);HCG日低剂量组Gn使用剂量、使用天数及卵泡数明显少于常规量组(P=0.004;P=0.000);低剂量组无取消周期,常规量组有5个取消周期。结论:低剂量CC的促排卵效果与常规剂量相同,同时降低对子宫内膜厚度的影响及多卵泡发育的风险,副作用低,有重要的临床应用价值。
