The effect of bed rest after intrauterine insemination on pregnancy outcome

Abstract

Objective: To compare the effect of bed rest after intrauterine insemination for 5, 10 and 20 mins on the pregnancy rate. Design: Randomized controlled trial. Setting: Integrated Fertility Center and Agial Fertility Center. Sample: Three hundred and 96 couples with mild male factor, cervical factor, or unexplained infertility between the periods from 1/2012 to 12/2012. Methods: Intrauterine insemination with controlled ovarian hyper-stimulation. Main outcome measures: The chemical and clinical pregnancy rates. Results: The couples were randomly subdivided equally into three groups: A, B, & C and they allocated for bed rest for 5, 10 and 20 min, respectively after insemination, the chemical and clinical pregnancy rates in group A (6.1% and 4.5%, respectively) were significantly lower than in group B (18.2% and 15.9%, respectively), and also they were significantly lower than in group C (23.5% and 19.7%, respectively), but there was no statistically significant difference in the pregnancy rates between groups B and C. Conclusions: Bed rest for 10 and 20 min after intrauterine insemination has a positive effect on the pregnancy rate, but there is no statistically significance difference between them. We recommend bed rest for at least 10 min after intrauterine insemination.
