However, the study is limited by its retrospective nature and potential for selection and observer bias, given that the treating physician was also assessing all penile deformities as well as performing operative intervention.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>The presence of hinge effect can cause instability of erections during penetrative sex. Multiple factors may predispose patients to a hinge effect, including the quality of erection and severity of curvature. But when controlling for rigidity, a girth discrepancy &amp;gt;1\u00a0cm did appear to be associated with a hinge. While many factors, such as baseline erectile dysfunction and severity of curvature, are important in determining the optimal surgical intervention, assessing for preoperative hinge effect also influenced the surgical approach.<\/jats:p>\n
