To assess the predictive value of endometrial ultrasonography and age for the outcome of in vitro fertilization-embryo transfer (IVF-ET).
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.
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.
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.
评估子宫内膜超声检查及年龄对体外受精 - 胚胎移植（IVF - ET）结局的预测价值。
共研究了305例输卵管阻塞的女性。进行超促排卵，并在注射人绒毛膜促性腺激素（hCG）当天采用经阴道超声检查监测子宫内膜厚度及内膜形态。通过超声检查子宫内妊娠囊来诊断妊娠。
妊娠组与未妊娠组在子宫内膜厚度或内膜形态方面未发现差异，但妊娠所需的最小子宫内膜厚度为7毫米。20 - 34岁女性的妊娠率高于35岁及以上女性。
在注射hCG当天经阴道超声检查所测得的子宫内膜厚度及内膜形态均无法可靠预测妊娠情况。妊娠所需的最小子宫内膜厚度为7毫米，20 - 34岁女性的妊娠率高于35岁及以上女性。
