Sensory changes after surgical correction of penile curvature.

In 32 men (mean age 54.94 years, range 25-70 years), thresholds for penile thermal and vibratory sensation were recorded before and 3 months after surgery using a genital sensory analyser. The following significant changes were found postoperatively. The cold threshold decreased in the glans from 27.24 to 25.33 degrees C (P<0.001) in men older than 60 years, and in the ventral penile shaft from 28.54 to 25.46 degrees C (P<0.001) in men aged 35-59 years. The warm threshold increased in the glans from 38.31 to 40.61 degrees C (P=0.002) in men aged 35-59 years, and from 39.20 to 40.58 degrees C in men older than 60 years (P=0.023). The warm threshold also increased in the ventral penile shaft in men aged 35-59 years, from 36.62 to 37.82 degrees C (P=0.023). For all three age groups combined, the vibratory threshold changed in the glans from 2.33 to 2.93 mum (P<0.001). It is concluded that penile sensitivity changed significantly after surgery for penile curvature treatment, regardless of whether a ventral or dorsal surgical approach is used.
