A systematic review of the evidence for complementary and alternative medicine in infertility

BackgroundThe use of complementary and alternative medicine (CAM) by patients and physicians has increased markedly in recent years. Many case reports, case series, and uncontrolled trials of varying quality have been completed; however, there is now a slowly increasing number of randomized controlled trials (RCTs) examining the use of CAM.ObjectivesTo identify, survey, and review RCTs investigating the use of CAM for infertility treatment.Search strategyThe MEDLINE and Cochrane databases were electronically searched.Selection criteriaRCTs examining modalities for treatment or improvement of health status were reviewed.Data collection and analysisRCTs were included based on use of objective measures, articles written in English, availability through the University of Michigan database, and clear published clinical outcomes.Main resultsThirty-seven articles assessing a variety of CAM modalities met inclusion criteria. Acupuncture, selenium supplementation, weight loss, and psychotherapeutic intervention had 3 or more studies demonstrating beneficial effect. Other interventions had been studied less and evidence for them was limited.ConclusionsAlthough there is preliminary evidence of the effectiveness of some CAM interventions among infertile patients, many of these interventions require further investigation before they can be considered for routine clinical use.
