输卵管原因不孕患者IVF-ET周期中子宫内膜的超声监测及年龄对妊娠的预测价值

目的 评价输卵管原因不孕患者IVF-ET中子宫内膜的超声监测及年龄对妊娠的预测价值.方法 输卵管原因不孕妇女05例,男方精液正常,采用长周期控制性超促排卵方法,于hCG注射日行阴道超声监测子宫内膜厚度、回声类型及临床妊娠情况.结果 妊娠组与未妊娠组子宫内膜厚度、内膜回声类型均无差异,但是妊娠所需的子宫内膜厚度至少为7 mm;而且20～4岁组的妊娠率高于≥5岁以上组.结论 hCG日超声监测子宫内膜厚度与回声类型对ⅣF-ET结局无明显预测性,但妊娠所需的子宫内膜厚度至少为7 mm,20～4岁组的妊娠率高于≥5岁以上者.

Predictive value of endometrial ultrasonography and age for the outcome of in vitro fertilization-embryo transfer

Objective To assess the predictive value of endometrial ultrasonography and age for the outcome of in vitro fertilization-embryo transfer (IVF-ET). Methods A total of 305 women with tubal occlusion were studied. Superovulation was induced and transvaginal ultrasonography was employed for monitoring the endometrial thickness and endometrial patterns on the day of human chorionic gonadotrophin (hCG) administration. Pregnancy was diagnosed by ultrasonography of the intrauterine gestational sac. Results No difference was noted in the endometrial thickness or endometrial patterns between pregnant and nonpregnant groups, but the least endometrial thickness essential for pregnancy was 7 mm. The pregnant rate of women aged 20-34 years was higher than that of women aged 35 years or above. Conclusions Neither endometrial thickness nor endometrial patterns detected by transvaginal ultrasonography on the day of hCG administration allows a reliable prediction of pregnancy. The least endometrial thickness essential for pregnancy is 7 mm and the pregnant rate of women aged 20-34 years was higher than those aged 35 years and above.
