In order to avoid the mistakes related to the use of the condoms, and, accordingly, the breach of the condoms, you are to respect the instructions given on the package. The most wide — spread mistakes in use of the condoms are as follows:

• Incomplete putting of the condom on the penis;
• Presence of air in the condom;
• Putting the condom off the penis after the complete disappearance of erection.

It is recommended to put the condom on at the very beginning of the sexual game and to put it off before disappearance of erection in order to avoid the leakage of sperm in the vagina.

The quality of the condoms and the major requirements for them are established by the standards. There are the various standards: the international ones (ISO - International Standardization Organization, WHO  the World Health Organization), the European standard EN, the national standards — NF (France), BS (Great Britain), DIN (Germany), GOST (CIS countries), etc.  The requirements stated in the standards, are usually similar, especially those of the national and European standards, EN and  ISO, that are completely harmonized. If the packing of the condoms bears the signs EN (DIN EN, NF EN è ò. ä.), that means that the product is in conformity with the common European standard.

You may use the additional lubricants containing the gel on the water base; they are usually sold in the sex shops. Besides, to moisture the vagina and to ensure the double contraceptive action, you may use, together with the condoms, «Pharmatex» in form of the suppositories, the capsules, the tampons or the cream, because «Pharmatex» is made on the base of water, to distinguish from the other local contraceptives, containing the hard fats as their base. The cosmetic creams (hand cream, Vaseline, even the oil for baby care), the fats and oils should never be used as the additional lubricant, as all of them cause the destruction of latex. The spittle is also not recommended due to the possible presence of the microbes.

NF  norm (NF is the French national standard of quality of the condoms, that is, at the same time, the evidence of the conformity to the general European quality standards) provides for 2 groups of the sizes, and the condoms are to correspond to them:

• — The length of 160 mm (minimum) and the width of 52   mm;
• — The length of 150 mm (minimum) and the width of 49 mm (minimum).

The different countries produce the various models varying, besides the other features, in size. The smaller sizes are produced in Japan for the internal market, but they are not practically sold here. Europe and America produce the small lots of the large sizes, and that is indicated on the packing. Really the penis of length of 200 mm and of width of 50 mm needs to use just the large size of the condom, but the dominant part of the men feels them good in the usual condoms.

Innotex offers two sizes of the condoms: the standard Innotex size (length — 170 mm, and width — 52 mm), and Innotex Plus (length — 200  mm, and width — 56 mm), they are also in conformity with the European standards.

It is recommended to buy the condoms in the Pharmacies, as only the Pharmacy may ensure the correct storage of the rubber objects for medical use. Buying in the kiosks, you have a risk to get the products of low quality, the falsified product or the product with the expired storage date.

Nonoxynol does not destroy latex but it is not used in the modern, high — quality condoms as a result of its negative influence on the organism. Nonoxynol is absorbed for 80% by the organism; it comes in the blood stream and destroys the mucous tunic of the vagina that makes it vulnerable for the infections. That’s why nonoxynol is contra — indicated for the breast — feeding mothers and for everyone who cares about his health.

HIV has a size of 100 nanometers in diameter. The molecule of water has a size of 20 — 60 nanometers in diameter; that is much lesser than the size of HIV. If water does not penetrate through the micropores of the condom, HIV also can not pass through, if, evidently, the condom is of high quality and is not damaged. Innotex condoms were tested in A. Fournier Institute in Paris (the WHO center for the research of sexually transmitted diseases) in December of 1988. During the tests Innotex condoms were verified for penetration of some viruses, being of even smaller size than AIDS virus. The results of the tests approved that no virus could penetrate through the membrane of the condom.

The tests with the use of the latest methods, held in Virus Oncology Laboratory in the Paster Institute in Paris, in September of 1989, approved that Innotex condoms form the unconquerable barrier for AIDS virus.

No scientific researches were made on that theme. But from the point of view of resistance of the materials, any decorations lead to the appearance of the point of extremely low reliability, that’s why it is better to use the shaped condoms just for fun and amusement, not for the contraception.

The condoms of the various brands have the different content. The possibility of allergic reaction on condoms is low enough, but it exists. That’s why try not to use the condoms of the brand that could cause, according to your opinion, the allergic reaction. If the situation remains the same, you need to appeal to the gynaecologist for examination.

Yes, you have to use the condom even in this case. Primary, one of the partners could receive HIV infection by non — sexual way of transfer. Besides, the condom protects you even from such a simple virus as herpes. A lot of people suffer with clamidiosis that passes usually without the symptoms. Besides, the condom may protect you against the undesirable pregnancy.

The reliability of the condoms makes 99%. That means that the unplanned pregnancy may appear only in 1 case of one hundred (usually due to the incorrect use, bad quality or violation of storage conditions of the condom). No researches confirm the efficiency of use of two condoms put one over another. But the risk of their damage or sliding is increased in this case due to the frictions between them. The double guarantee may be really achieved when using the condom together with Pharmatex local contraceptives, produced in forms of the vaginal capsules, ovules, suppositories, tampons or cream.
