US Patent 9125688 Insemination apparatus and method

An apparatus and method for in vivo fertilization through self-insemination includes sleeve fabricated of soft silicone elastomer having a tubular portion and a distal bulbous head. The sleeve may be secured concentrically about a syringe approximating the size, configuration, and feel of a human penis. The bulbous head includes lobes arrayed at equal angles about the head, adjacent lobes being separated by narrow channels extending longitudinally to provide a flow space for air and fluids. The distal stem of the syringe extends through the sleeve at the distal end thereof. Thus seminal fluid discharged from the syringe will be ejected out of the central opening in the head of the sleeve.
