title: The Conception and Evaluation of Sexual Health Literature.
abstract: Understanding the appropriate evaluation and development methods for studying the literature as it pertains to sexual health is important for those practicing within the subspecialty.
  
  
  
  To further understand the methodology that is necessary to evaluate and design optimal studies in sexual health.
  
  
  
  A PubMed search was performed using the terms urologic study design, urologic validated questionnaires, clinical trials, and study bias. Articles with current and relevant topics in sexual health were selected for evaluation.
  
  
  
  Summary of the current state of sexual medicine literature with insights into the evaluation and development of this literature.
  
  
  
  Most of the urologic and sexual medicine literature consists of retrospective studies that have resulted in low levels of evidence. Case series, case-control studies, cohort studies, and experimental studies are designs commonly used in sexual health. There are numerous types of bias that decrease the validity of the results within the literature. There are multiple validated questionnaires that can decrease bias when collecting data. These instruments are preferred over non-validated questionnaires and can help discern whether an intervention improves a patient's quality of life. The quality of the literature varies and often reflects the incidence of the condition being studied.
  
  
  
  Those caring for patients with sexual dysfunction need to recognize the quality of the literature they read and understand the means of developing the highest quality studies, recommendations, and published literature.
