Interestingly, the median values for vibration perception were similar for the phallus and the unoperated forearm. Pressure sensibility was present at the phallus, but less than at the forearm. Moreover, sharp-blunt sensibility was present in 11 patients. In contrast, clear cold-warm discrimination could not be achieved, although the majority of patients detected the cold stimulus. A two-point discrimination of up to 23\u00a0mm could not be detected in either body part. 15 patients experienced orgasms without difficulty after 23\u00a0months (n\u00a0=\u00a020 after 54\u00a0months).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Clinical Implications<\/jats:title>\n                  <jats:p>We observed successful recovery of sensibility at the phalli for the majority of patients, including the preservation of orgasm.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Strengths &amp; Limitations<\/jats:title>\n                  <jats:p>Our institution is one of the few centers regularly performing phalloplasties in transgender patients, especially preferring the technique of Gottlieb and Levine.
