Abstract: This invention relates to a device for providing therapeutic support to the penis of a man who suffers either partial or total sexual impotence, which device thereby allows nearly normal sexual activity between him and his partner. The device comprises parts that are mounted on spring-loaded hinges that create external pressures on the corpora cavernosa, the erectile tissues within the penis, compressing them so less blood is required to achieve erection and/or maintain the penis in an erect state. A significant feature of this invention is that it can be applied to or removed from the penis after coitus has begun and without complete disengagement of the male organ from the female.
