Ultrasonographic evidence that bedrest after embryo transfer is useless.
BACKGROUND
To demonstrate the effect of immediate ambulation after embryo transfer on the intrauterine location of the transfer content.


METHODS
Prospective observational randomized controlled study.


RESULTS
Fifty-seven patients (47.5%) had one air bubble at transfer and after 15 min change in position: group A (bedrest) 2.69 mm, group B (immediate ambulation) 2.00 mm (p = 0.511). The distance from the fundus declined by 26% in group A and 15% in group B (p = 0.229). Twenty-eight patients (23.3%) had two air bubbles at transfer and after 15 min: average change in position of the first air bubble: group A 3.07 mm, group B 1.80 mm (p = 0.282); average change in position of the second air bubble: group A 2.69 mm, group B 1.80 mm (p = 0.450). The distance from the fundus for the first air bubble declined by 2% in group A and 18% in group B (p = 0.593) and for the second air bubble by 22% in group A and 15% in group B (p = 0.711).


CONCLUSIONS
This study demonstrates that the transfer content is not affected by the immediate ambulation after transfer, illustrating why there is no rationale for bedrest after transfer.
