Disclosed herein is a method of phalloplasty for girth enhancement. It comprises incising minimally the outer skin of a penis; separating the skin and the hypoderm from a part immediately above Buck's fascia and peeling off the skin and the hypoderm in a region ranging from a part proximal to a glans to prepubic junction; forming a mesh structure of multiple slits in a penile implant; and fixing the penile implant to the penis by suture. The formation of a mesh structure of multiple slits or the use of an implant in multiple pieces makes it possible to cope with complications, thereby significantly reducing complications. Also, the multiple slits or multiple pieces form spaces therebetween, which lead to an increase in flexibility between the implant tissues, thereby enjoying the advantages of minimizing discomfort upon erection and reducing the occurrence of penis curvature. The delicate irregularities of the penis may serve as a factor promoting sexual stimulation upon sexual intercourse. Also, upon carvenosal injection therapy for erectile dysfunction, drugs for inducing erections can be easily injected into the space between the multiple slits or multiple pieces.
