ZSI 475 FTM Hydraulic Penile Implant

ZSI 475 FTM Hydraulic Penile Implant The ZSI 475 FTM is the first-ever hydraulic penile implant designed specifically for trans men!

Made by Zephyr Surgical Implants of Switzerland, the ZSI 475 FTM Hydraulic Penile Implant is designed to provide excellent stability and cosmetic results.

The ZSI 475 FTM is made of NUSIL silicone which is manufactured at a density that is ideal for longterm durability, malleability and providing a lifelike erection. The reinforced nickel-titanium rod interior increases the lifespan of the implant.

Important note: Zephyr penile implants are not available in the USA and ZSI is not currently seeking FDA approval. At this time, they are available in Australia, New Zealand and in some countries in Europe and South America. View a map of surgery centers around the world that are using Zephyr penile implants.

Other features of the ZSI 475 FTM:

  • One cylinder instead of two, providing excellent cosmetic results when inflated and deflated.
  • Available in three sizes: 120mm, 150mm, 170mm in length.
  • A 25mm wide, realistically shaped glans "stopper" is affixed to the tip of the implant. The glans is shaped with a small indentation that serves as a passage for the urethra, easing implantation.
  • The proximal part of the implant has a plate made from stainless steel and silicone which is fixed securely to the pubic bone.

Here's video explaining implantation of the ZSI 475 from the team in Belgium (Lumen, Spinoit, Hoebeke.)


Zephyr also has a malleable penile implant, the ZSI 100 FTM.

View all the studies examining Zephyr Surgical Implants. These studies looked at surgical outcomes, complication rates, device survival, and patient satisfaction in ZSI's malleable and hydraulic implants. For patients, this information matters because it helps set realistic expectations, informs decisions about which implant may be right for them, and highlights the importance of close follow-up after surgery.
