ZSI 100 FTM Malleable Penile Implant
The
ZSI 100 FTM is the first-ever penile implant designed
specifically for trans men!
Made by Zephyr Surgical Implants of Switzerland, the ZSI 100 FTM Malleable Penile Implant is designed to provide excellent stability and cosmetic results.
The ZSI 100 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 implant is adjustable at the distal end from 16cm to 13cm. A 25mm wide, realistically shaped glans "stopper" is affixed to the tip of the implant. The cylinder is 22mm wide and designed for comfort and appearance. The ZSI 100 FTM's proximal part is made of silicone and stainless steel and is fixed to the pubic bone.
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.
The implant functions like other semi-rigid implants to obtain an erection: manually straighten and lift the penis to an erect position. Return to the bent position for a flacid penis.
Zephyr also has a hydraulic penile implant, the ZSI 475 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.
