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.
