To evaluate the results of cervical dilatation during an ovum pick-up session in patients with cervical stenosis who participated in an IVF-ET program.
A retrospective study.
In vitro fertilization-ET unit.
PATIENT(S): Forty-one treatment cycles in 22 patients with known cervical stenosis. In all patients previous transcervical ET had been either extremely difficult or impossible.
INTERVENTION(S): Cervical dilatation under general anesthesia during an ovum pick-up session, 48 hours before transcervical ET.
MAIN OUTCOME MEASURE(S): Ease of ET procedure and clinical pregnancy rate (PR).
RESULT(S): Cervical dilatation was performed in 41 IVF-ET cycles and resulted in easier transcervical ET in 39 cycles, but only one clinical and one extrauterine pregnancy.
CONCLUSION(S): Cervical dilatation during the ovum pick-up session leads to easier ET in patients with cervical stenosis, but PRs after this procedure are very low.
评估参与体外受精-胚胎移植（IVF-ET）项目的宫颈狭窄患者在取卵过程中宫颈扩张的效果。
一项回顾性研究。
体外受精-胚胎移植科室。
22例已知宫颈狭窄患者的41个治疗周期。所有患者既往经宫颈胚胎移植均极其困难或无法进行。
在经宫颈胚胎移植前48小时取卵过程中全身麻醉下进行宫颈扩张。
胚胎移植操作的难易程度及临床妊娠率（PR）。
41个IVF-ET周期进行了宫颈扩张，其中39个周期经宫颈胚胎移植更容易，但仅1例临床妊娠和1例宫外孕。
取卵过程中宫颈扩张使宫颈狭窄患者的胚胎移植更容易，但该操作后的临床妊娠率非常低。
