A urologist can place a prosthetic erectile device which will allow you to maintain an erection. As of September 2022, no implantable prosthetic devices have been FDA-approved for phalloplasty. Instead, the surgeon can use a device intended for patients with erectile dysfunction to allow transmasculine patients to achieve an erection. There is a risk of infection and implant rejection with an erectile implant. If this happens, it may take six months before another device can be placed into the penis.
