Abstract:
Disclosed is an anti-slip condom, comprising a condom body. The condom body is provided with an opening end (4), a closed end (3), a male side (1) and a female side (2), wherein a part not occupying less than 5% of a bottom face of the male side (1) has a primary microstructure (8, 9, 10, 11, 13) capable of increasing a surface area, and the area ratio of the total surface area including the primary microstructure (8, 9, 10, 11, 13) on the unit area of the bottom face of the male side (1) to the unit area is 1.05-565.00. The condom can remain fitted to the penis of a male during sexual intercourse, can reduce relative sliding between the condom and the skin of the penis, and does not tend to form wrinkles or come off, thereby reducing mucosal injury and improving a sense of reality. The condom is helpful in improving a consumer's willingness to use a condom, and facilitates the prevention of sexually transmitted diseases.
