These reviews provide comprehensive, science-based information on common, costly medical conditions, and new health care technologies and strategies. Systematic reviews are the building blocks underlying evidence-based practice; they focus attention on the strength and limits of evidence from research studies about the effectiveness and safety of a clinical intervention. In the context of developing recommendations for practice, systematic reviews can help clarify whether assertions about the value of the intervention are based on strong evidence from clinical studies. For more information about AHRQ EPC systematic reviews, see www.effectivehealthcare.ahrq.gov/reference/purpose.cfm. AHRQ expects that these systematic reviews will be helpful to health plans, providers, purchasers, government programs, and the health care system as a whole. Transparency and stakeholder input are essential to the Effective Health Care Program.

We assessed the effectiveness of imaging for identifying and correctly locating testicles, the use of hormonal stimulation for treatment planning and hormones for achieving testicular descent, and choices among surgical treatments, including surgical approach (open vs. laparoscopic). Data sources. We searched MEDLINE® via PubMed, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Embase, as well as reference lists of included studies. Review methods. We included studies published in English from January 1980 to February 2012. We included studies of prepubescent males with cryptorchidism. For treatment planning studies, we included all designs except case reports. Imaging studies needed to have confirmatory surgical data. For treatment studies, we required an appropriate comparison arm. We excluded studies of disorders of sexual development or ambiguous genitalia. Two reviewers independently assessed the quality (risk of bias) for each study and the overall strength of the evidence, with discrepancies adjudicated by a third reviewer. Results. We identified 60 unique studies meeting our review criteria; eight were of good, eight were of fair, and 44 were of poor quality. The accuracy of imaging to identify the presence or absence of testicles was 21 to 76 percent for ultrasonography (US), 42 to 92 percent for magnetic resonance imaging (MRI), 60 percent for computed tomography (CT) scan, and 100 percent for magnetic resonance
