The "Mini Condom" device is designed to cover only the head of the penis, it comprises of a condom having two relatively heavily elasticised annular bands, the first elasticised band to lie around the base of the head of the penis, to be followed by a skirt of approximately one centimetre and the second elasticised band to lie approximately one centimetre below the first band and approximately half centimetre above the end of the condom, these two elasticised bands in such positions are such as to provide more positive seal and prevent semen progressing down the penis beyond said seals. A conventional condom is also provided with an integral elasticised annular rubber band adapted to form a seal around the base of the head of the penis with such enclosed sac to be with or without such solidifying agent adapted to cause the ejaculated fluid to gel and/or solidify thereby immobilising the sperm. |
