Recognizing the specific needs of transmen, specific erectile devices were developed in the form of a single
[6]
cylinder device with a fixation plate, which better conforms to the anatomy of a neophallus .

This study assessed the initial surgical outcomes after implantation of the malleable ZSI 100 FTM and the
inflatable ZSI 475 FTM prostheses in transgender men after MLD neophalloplasty. Several previous studies
have reported outcomes for prostheses specifically designed for transgender men following radial free
forearm flap and anterolateral thigh flap neophalloplasty [14,18-20] . However, no information is available on the
implantation of these innovative erectile devices after MLD free flap neophalloplasty.

In a native penis, overall complication rates (infection, erosion or device dysfunction) for penile prosthesis
[21]
implantation are < 2%, significantly lower than the rates observed in neophallus implants . In transgender
men, studies of penile prostheses designed for cismen following neophalloplasty report overall complication
rates of 23.9%-47.6%, while the rates for transmen-specific prostheses were 28.4%-44% [15,22,23] .
