Penile Implants

What is a penile implant?

A penile implant (penile prosthesis) is a surgically implanted medical device used to treat erectile dysfunction (ED)when other treatments (tablets, injections, vacuum devices) are ineffective or unsuitable. Implants are placed entirely inside the body and allow a man to have a reliable erection for sexual activity.

There are two main types of penile implants:

  • Malleable (semi-rigid) implant

  • Three-piece inflatable implant

Types of penile implant:

Three-Piece Inflatable Penile Implant

What is it?

A three-piece implant consists of:

  • Two inflatable cylinders in the penis

  • A fluid reservoir placed in the lower abdomen

  • A pump placed in the scrotum

Squeezing the pump transfers fluid into the cylinders to create an erection. Pressing the release valve returns the penis to a flaccid state.

Advantages (Pros)

  • Most natural look and feel

  • Penis is soft when deflated, firm when inflated

  • Best cosmetic and functional result

  • High patient and partner satisfaction rates

  • Easier to conceal under clothing

Disadvantages (Cons)

  • More complex surgery

  • Slightly higher risk of mechanical failure over time

  • Requires good hand function to operate the pump

  • Higher cost than malleable implants

Malleable Penile Implant

What is it?

A malleable implant consists of two bendable rods placed inside the erectile chambers (corpora cavernosa) of the penis.
The penis is manually positioned up for intercourse and down for daily activities.

Advantages (Pros)

  • Simple design with fewer mechanical parts

  • Very reliable – lowest risk of mechanical failure

  • Easier surgery with shorter operating time

  • Lower cost than inflatable implants

  • Good option for:

    • Men with limited hand dexterity

    • Complex medical conditions

    • Previous infections or multiple surgeries

Disadvantages (Cons)

  • Penis is always semi-firm, not fully flaccid

  • Can be more noticeable under clothing

  • Less natural appearance compared to inflatable implants
