First, AIDS, hepatitis B, human papilloma virus, such as smaller than the sperm, condoms may not be able to block sperm blocking viruses. Traditional condoms are about more than 100 million each for more than 120 nano-aperture, the latex film body exists 5000-70000 nanometers natural fissures, and may only be similar to human sperm size of the diameter of particles (diameter about 3000 nm) the effective barrier , while for diameter equal to or less than 120 nano-particles, and can not be completely blocked, ie, 42 nm hepatitis B virus, 50 ~ 55 nm of human papilloma virus, HIV virus, 120 nm is entirely possible through traditional natural rubber latex condoms;

Second, the HIV virus can invade through multiple channels genital mucous membranes, skin, sperm, only this the only channel into the fallopian tube;

Third, pregnancy by ovulation time constraints, while the HIV-infected without any time limit.

These factors have determined that even if the correct use of condoms, HIV, hepatitis B, human papilloma virus, such as a higher probability than the pregnancy.

Not only that, the German Institute for disclosure of a risk assessment of new research information: latex condoms during the curing process can generate a carcinogenic substance - N-nitrosamines. Animal experiments showed that local application of the skin and mucous membrane of about 1g total N-nitrosamines, it will induce local or systemic tumors, especially liver cancer. Although the release of nitrosamines from condoms is far failed to achieve this measurement, but if the frequency of use frequently, there is still the potential risk of inducing tumor. In addition, some people allergic to latex protein, the use of latex condoms allergy might occur after the behavior. And the traditional condom was acidic, would undermine women's vaginal acid-base balance, easy to induce a variety of gynecological diseases

As things stand, density is not sufficient to effectively block HIV, hepatitis B and other viruses; there carcinogens nitrosamines; latex protein allergy cited; and natural latex condoms, alkaline and became the traditional latex contraceptive sets can not overcome the four major flaws. Traditional latex condoms does not mean safe!

Currently on the market a new condom, using no toxic side-effects within and outside the membrane body is made of natural plant extracts, will contain carcinogenic substances, including natural latex-based film coating. With Na Valley technology to produce a new condom's unique composition and three-tier structure to solve the traditional condoms can not be 100% effective prevention of AIDS, hepatitis B, human papilloma virus, and other issues, fully compensate for the shortcomings of the traditional condom filled international blank.
