This paper reviews the various types of penile prostheses currently available in clinical practice. The advantages and disadvantages of each type of prosthesis are discussed. Practical factors to be considered in choosing the type of prosthesis offered to a patient are emphasised. The paper provides an outline of the important steps in the implantation surgery and also emphasises the need for patient and partner to have realistic expectations of the surgical result. While recognising the multiple forms of management of erectile impotence now available, the paper emphasises the high level of patient satisfaction which can be achieved using a penile prosthesis as the form of management of erectile impotence.
