<p><P>PROBLEM TO BE SOLVED: To solve the problem in which the sexual desire of a wearing person cannot be satisfied since physical stimulation to the penis is restricted because slip between the surface of the penis of the virilia and the surface of the inside of a condom is very little and both of them are kept to nearly adhere to each other and lubricity is not sufficient even when a lubricant is applied, in the conventional condom. <P>SOLUTION: The condom has a hydrophilic part 3 formed on the surface of the inside on a distal end side excepting for the root side of the condom 1 molded of a hydrophobic material. The ratio of the length 1 of the hydrophilic part 3 to the full length L of the condom excepting for a sperm accumulation part can be set within 20% to 80%, whereas, when the ratio is set within 25 to 45%, improvement in lubricity and the preventing effect on falling can be set well-balancedly. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
