There are two types of condom: male and female.
Male condoms are made of either thin latex which is a form of rubber or polyurethane. The latex variety is commonly available. The polyurethane condoms are useful for those who are allergic to latex. Recently condoms of various sizes have been introduced. Some condoms contain spermicides, but these chemicals can cause allergies and there are reports to suggest that they may actually increase the risk of transmitting infections.
The condom is usually very effective. If 100 women used it over a period of one year then only two women would get pregnant. Success of the condom depends on the man using it. The commonest cause of failure is that either he forgot to wear it or else he wore it too late or too roughly such that it tore. It can also tear in case the couple uses oil based lubricants / creams / oils that can make holes in the c ondom.
Nowadays there are condoms that are ribbed or coated with fruit and chocolate flavors in an attempt to increase the acceptability. It is difficult to say whether they affect the efficacy.
The female condom is made of polyurethane, and has two rings: first – round the opening and another one at the closed end – which is the end that goes into the top of the vagina. The woman needs to wear the condom before sex. The closed end has to be inserted inside the vagina and the ring on the open end fits on the
vaginal opening covering the clitoris. Thus the vagina is lined completely by the condom. After sex it is important to remove and discard the condom.One advantage of the female condom over the male condom is that the use of the method is under the control of the woman.
It is advisable for all sexually active couples to use condoms not only for prevention of pregnancy but also for prevention of infection. In short it should be used at every conceivable occasion.
