  • Patent number: 5318042
    Abstract: A condom which has a sheath which is open at one end and closed at the other. The sheath includes a cylindrical portion of constant diameter and a portion of larger diameter between the portion of constant diameter and the open end. The open end is encircled by a ring which is of the same diameter as the constant diameter portion. The two portions are co-axial. The portion of larger diameter in use provides a pouch intended to receive and envelope the wearer's scrotum and a region which is diametrically opposed to said pouch and which ruffles thereby providing a series of circumferentially extending ridges which ridges inhibit blood flow from the penis and provide for female stimulation. In a modified form there is a teat at the closed end. In another form there is a further portion of constant diameter, smaller than the larger diameter portion, between said latter portion and the open end.
