Product Description

The Prepex Circumcision Device is a medical device which facilitates non-surgical adult male circumcision without the use of anesthesia, surgery, suturing or sterile setting. It is designed to improve and advance the circumcision experience for the patient and the related ecosystem, in order to achieve rapid scale-up of voluntary medical male circumcision (VMMC) in resource limited settings and reduce transmission of HIV/AIDS and other infectious diseases.

Design Specifications

The Prepex Circumcision Device consists of an inner ring, elastic ring, placement ring, and a verification thread; there is also a sizing accessory, a template with 5 holes of differing size to guide the selection of ring size. The device works by compressing the foreskin so as to cut off circulation distally, after which the distal foreskin becomes necrotic, allowing easy and bloodless removal.

Technical Support

Healthcare professionals are trained over a period of 3 days to 2 weeks. A Prepex training program is available to physicians.

Replacement Components



The components are created for single use and disposal.

Manufacturer Specified Performance Parameters

The PrePex device enables non-surgical adult male circumcision.

Vetted Performance Status

Mean time to complete healing was 25.3 days after foreskin removal or 32 days after device placement. The PrePex device was safe and effective as a means of performing bloodless adult male circumcision that can be carried out by nonphysician staff without need for anesthesia, suturing, or sterile settings. The mean PrePex skin-to-skin procedure time is 3.1 minutes. 91 of 92 patients (99%) in the PrePex group were satisfied with the aesthetics of circumcision. Ninety-one of 92 (99%) patients in the PrePex group would recommend the procedure.


This device is made for single use and disposal. The PrePex device should not be used in cases of phimosis or congenital abnormality.
