Abstract: The invention is an impotence support, horizontally split, made of plastics, to be fitted over the penis (2), for the performance of sexual intercourse with a shortened and slackened penis. The end portion (3) of the impotence support is rounded and tapers anatomically to fit and correspond to the deeper portion of the neck groove of the penis glans (22) with the longitudinal split (14) so located that the frenum (26) of the glans remains free. This ensures that the glans is kept free and makes possible extension of the penis and the retention of this state of extension during intercourse. The support end edges (15,16) lie hidden behind the glans (22) and the support does not protrude outside the ridge of the glans (22). Retention of the support in place can be ensured with a binding which extends over the longitudinal split (14).
