Phalloplasty: A panacea for 46,XY disorder of sex development conditions with penile deficiency?

Abstract

In cases of severe penile inadequacy, such as in pathological conditions involving penile amputation (e.g. penile cancer), or in 46,XY disorders of sex development with severe undervirilization or maldevelopment of the penis (e.g. idiopathic micropenis, cloacal exstrophy), standard (surgical) penile lengthening techniques do not provide patients with a phallus suitable for sexual intercourse. Genital dissatisfaction can lead to low self-esteem and psychosexual dysfunction. Therefore, phalloplasty, the gold standard in transgender surgery, may provide a possibility to achieve a satisfactory genital appearance and sexual function. Small series have reported cosmetically acceptable and erogenous sensate neophalli with incorporation of a neourethra to allow voiding in a standing position and with enough bulk to allow penile prosthesis insertion for pleasurable intercourse. Although early results seem promising, further publication of series with large numbers and longer follow-up is needed to evaluate to what extent phalloplasty improves physical and sexual outcomes. Complications are of particular concern because of associated scarring and loss of sensitive tissue. Without full preoperative workups assessing patients' expectations and reasons for undergoing surgery, they may still struggle with self/penile image and with psychological barriers for engaging in sexual activity. Recommendations for the psychosocial management of boys and men with penile deficiency are suggested.
