OBJECTIVE
To compare pregnancy rates (PRs) after ultrasound-guided embryo transfer and embryo transfer based on ultrasonographic length measurement.
DESIGN
Prospective intervention group combined with retrospective control group.
SETTING
University fertility clinic.
PATIENT(S): Patients undergoing IVF and intracytoplasmic sperm injection.
INTERVENTION(S): Transabdominal ultrasonographic guidance at embryo transfer.
MAIN OUTCOME MEASURE(S): Pregnancy and implantation rates.
RESULT(S): In 367 ultrasound-guided embryo transfers clinical PR, ongoing PR, and implantation rate were 35.1%, 31.1%, and 24.3%, respectively. In 363 embryo transfers based on previous ultrasonographic length measurement, the rates were 33.9%, 29.5%, and 24.2%, respectively. There were no statistical significant differences between the groups.
CONCLUSION(S): Ultrasonographic guidance does not show any benefit in terms of PR and implantation rate compared to previous ultrasonographic length measurement, an other precise and atraumatic transfer technique.
目的
比较超声引导下胚胎移植与基于超声测量长度的胚胎移植后的妊娠率（PRs）。
设计
前瞻性干预组与回顾性对照组相结合。
地点
大学生育诊所。
患者
接受体外受精和卵胞浆内单精子注射的患者。
干预措施
胚胎移植时经腹超声引导。
主要观察指标
妊娠率和着床率。
结果
在367例超声引导下胚胎移植中，临床妊娠率、持续妊娠率和着床率分别为35.1%、31.1%和24.3%。在363例基于先前超声测量长度的胚胎移植中，这些比率分别为33.9%、29.5%和24.2%。两组之间无统计学显著差异。
结论
与先前精确且无创的基于超声测量长度的移植技术相比，超声引导在妊娠率和着床率方面未显示出任何优势。
