Condom products on the market are mainly made of natural latex with natural cracks between 5000 and 70000 nm, which is enough to prevent human sperm head with a diameter of 5000 nm. However, the diameter of HIV is only 120 nm, the diameter of human papillomavirus is between 45 and 55 nm, and the diameter of large spherical particles in hepatitis B virus is 42 nm.
