Condoms help prevent pregnancy and sexually transmitted diseases (STDs), they create a barrier that keeps semen and other body fluids out of the vagina, rectum or mouth.

Condoms help protect the body from sexually transmitted diseases and are effective in preventing pregnancy. However, due to the cultural tradition of Vietnamese people, they are often hesitant to mention sensitive issues, so in addition to their uses, many people still do not have a clear understanding of other issues such as how to use, size, and classify condoms.
