3种不同剂量来曲唑的促排卵效果及妊娠情况比较

目的 比较3种不同剂量来曲唑的促排卵效果及妊娠情况.方法 将该院2013年1月至2014年12月收治的92例Ⅱ型排卵障碍的不孕患者分为三组,第1组和第2组在月经第3天分别给予来曲唑2.5、5.0 mg/d,共5d,第3组在月经第3天单次口服来曲唑20 mg.观察人绒毛膜促性腺激素(HCG)注射日的卵泡成熟时间、成熟卵泡个数、排卵率、卵泡未破裂黄素化综合征(LUFS)及临床妊娠率等.结果 3组HCG注射日的卵泡成熟时间、成熟卵泡个数、排卵率及临床妊娠率差异均无统计学意义(P＞0.05).LUFS发生率差异有统计学意义(P＜0.05).结论 3种不同剂量来曲唑促排卵效果及临床妊娠率比较没有差异,但2.5 mg/d组LUFS发生率较高,临床工作中可根据实际情况选择给药方式.

Comparison of effects of three different doses of letrozole on ovulation induction and pregnancy situation

Objective To compare the effects of three different doses of letrozole(LE) on the promoting ovulation and pregnancy situation.Methods A total of 92 infertility patients with type Ⅱ ovulation disorder in this hospital from January 2013 to December 2014 were divided into three groups.The first group and second group were respectively given LE 2.5 mg/d and 5.0 mg/d from 3 d of menses for 5 d.The third group took LE 20 mg at draught on 3 d of menses.On the HCG injection day,follicle maturity time,number of mature follicles,ovulation rate,luteinized unrupture follicle syndrome (LUFS) and pregnancy rate were observed.Results The follicle maturity time,number of mature follicles,ovulation rate and clinical pregnancy rate on HCG injection day had no statistically significant difference among the three groups (P＞0.05).The incidence of LUFS had statistically significant difference(P＜0.05).Conclusion The promoting ovulation effect and clinical pregnancy rate have no difference among 3 different LE doses,but the occurrence rate of luteinized unruptured follicle syndrome(LUFS) in the 2.5 mg/d group is higher,therefore in the practical work,the medication administration mode may be selected according to the actual situation.
