To assess whether bed rest following the embryo transfer (ET) procedure contributes to the implantation process and pregnancy rate.
A prospective (patient-influenced) study.
An in vitro fertilization (IVF) unit of an academic medical center.
PATIENT(S): Four hundred six patients undergoing controlled ovarian hyperstimulation and IVF.
INTERVENTION(S): All women undergoing in vitro fertilization-embryo transfer (IVF-ET) cycles in our unit were given a special individual counseling session before the ET procedure in which they were informed that our previous experience showed no advantage for bed rest over immediate ambulation after ET. The women were allowed to select the practice of their choice, and they were assured that their decision would have no influence on their further treatment.
MAIN OUTCOME MEASURE(S): The stimulation pattern and cycle outcome were compared between the two groups (bed rest and immediate ambulation).
RESULT(S): Of the 406 patients counseled during the study period, 167 preferred immediate ambulation and 239 opted to stay in the unit for 1 hour's bed rest. There were no significant differences between the groups in mean patient age, number of embryos transferred, and other variables of the assisted reproductive technique cycles. Pregnancy rates did not differ between the groups: 41 out of 167 (24.55%) in the immediate-ambulation group and 51 out of 239 (21.34%) in the bed-rest group.
CONCLUSION(S): Immediate ambulation following the ET procedure has no adverse influence on the ability to conceive.
评估胚胎移植（ET）术后卧床休息是否有助于着床过程和妊娠率。
一项前瞻性（受患者影响）研究。
一所学术医疗中心的体外受精（IVF）单元。
406例接受控制性卵巢刺激和IVF的患者。
在我们单元接受体外受精 - 胚胎移植（IVF - ET）周期的所有女性在ET术前均接受了一次特别的个性化咨询，告知她们我们之前的经验表明ET术后立即活动比卧床休息没有优势。女性可以选择她们喜欢的做法，并确保她们的决定不会影响其后续治疗。
比较两组（卧床休息组和立即活动组）的刺激模式和周期结局。
在研究期间接受咨询的406例患者中，167例倾向于立即活动，239例选择在单元内卧床休息1小时。两组患者的平均年龄、移植胚胎数和辅助生殖技术周期的其他变量之间无显著差异。两组的妊娠率无差异：立即活动组167例中有41例（24.55%），卧床休息组239例中有51例（21.34%）。
ET术后立即活动对受孕能力没有不利影响。
