ABSTRACT:
A new and useful contraceptive and prophylactic attachment having a dome shaped bowl which conforms to the shape of a portion of the penile glans surrounding the urethral orifice. The bowl has an aperture overlying the orifice which leads into a collapsed bladder contained within a protective retaining structure. During ejaculation, semen flows through the aperture into the bladder expanding it and causing it to extrude itself through an expandable outlet in the retaining structure. As a penile cap or micro-condom, the shape of the bowl and a layer of medical grade adhesive forms a leak-free seal between the attachment and the penis. The sensitive corona of the glans is left exposed.
