Bed rest after embryo transfer: a randomized controlled trial.

OBJECTIVE

To determine whether bed rest after embryo transfer leads to improved pregnancy rates (PR).

DESIGN

Randomized controlled trial.

SETTING

University reproductive health clinic.

PATIENT(S): Women undergoing IVF.

INTERVENTION(S): Patients undergoing 164 cycles of IVF were randomized to 30 minutes of bed rest after embryo transfer or immediate discharge from the clinic.

MAIN OUTCOME MEASURE(S): Clinical PR defined by visualized fetal heart beat and ongoing PR defined by viable intrauterine gestation beyond 11 weeks.

RESULT(S): The clinical and ongoing PR for both groups were 50% and 46.3%, respectively, with no statistically significant difference between the two groups.

CONCLUSION(S): Thirty minutes of bed rest after embryo transfer does not improve PR.
