Changes

The [[Prepex]] device works by clamping the foreskin so that it is starved for blood, dies and falls off. In two cases observed during testing in Kenya the necrotic foreskin interfered with urination. This can occur only when medical personnel use the Prepex device to do a circumcision so it is appropriately classified as [[iatrogenic]]. The PrePex was withdrawn from the market in 2019.
