Description

  The present invention relates to a male contraceptive.

  It is common for male contraceptives to be coated and used near the base of the penis. However, although a general male contraceptive device can achieve the purpose such as contraception by covering it near the base of the penis, since the whole penis is covered, the pleasure at the time of sexual intercourse is inferior. Moreover, since the conventional condom is long, attachment and detachment of the penis took time and effort.

  As a prior art, a male contraceptive for covering and using a glans is disclosed (patent documents 1 and 2).

There is also known a male contraceptive device that is used by being attached to a glans (Patent Document 3).
Here, the male contraceptive device described in Patent Document 3 is attached with a cord so that it can be easily taken out when it is taken out in the female container, and a rubber forming a ring is attached to the end of the string. .

  Patent Document 4 discloses a male contraceptive device that is used by sticking a sticking sheet made of a flexible material on a glans head.
