A traditional condom is made of a rubber thin film without through holes, is watertight, and takes into consideration the fact that bacteria, viruses and microorganisms are cut off so as to avoid cross infection between both a man and a woman. The traditional condom mainly stops sperms from entering a vagina and a uterus, and accordingly the purpose of active contraception is achieved. The traditional condom also has adverse factors, the completely-closed rubber thin film stops body fluid exchange as well, body fluid includes water, protein capable of achieving a lubrication function, small organic molecules, female hormones and male hormones, and an interaction channel of human body bioelectric currents is also cut off. After the traditional condom is used for a long time, adverse effects can be brought to both the man and the woman. A condom with transparent tiny holes can stop bacteria, viruses and microorganisms, body fluid and human body bioelectricity can be transmitted as well, and therefore human health and sexual life harmony can be promoted.
