A randomized study of the effect of 10 minutes of bed rest after intrauterine insemination.
OBJECTIVE
To evaluate the effects of 10 minutes of bed rest after intrauterine insemination (IUI) on the pregnancy rate.


METHODS
Prospective randomized study.


METHODS
University teaching hospital.


METHODS
One hundred sixteen couples with unexplained infertility.


METHODS
Patients were prospectively randomized either to immediate mobilization after IUI (group I) or to remain in a supine position for 10 minutes after the procedure (group II).


METHODS
Cumulative pregnancy rate.


RESULTS
Ninety-five couples were included in the analysis. Group I consisted of 40 couples (90 cycles), and group II consisted of 55 couples (120 cycles). The pregnancy rate per couple in group I (4 of 40 [10%]) was significantly lower than in group II (16 of 55 [29%]). The pregnancy rate per cycle in group I (4.4%) was also lower than in group II (13. 3%). With use of life-table analysis, the cumulative probability of pregnancy in group II was significantly higher than in group I.


CONCLUSIONS
A 10-minute interval of bed rest after IUI has a positive effect on the pregnancy rate. We recommend that mandatory bed rest for 10 minutes after IUI should be adopted into a standard practice.
