Condoms
Condoms are termed barrier methods of contraception in that they prevent the sperm and egg meeting. A male condom fits over the erect penis and a female condom loosely lines the vagina. If used effectively, the male condom is 98% effective and the female condom is 95% effective. Condoms are only effective if used properly, and must stay in place throughout sex. There is a small chance that they can split in which case the couple may wish to use emergency contraceptives. When used according to instructions, and for all types of sex (vaginal, oral and anal), condoms are the only method of contraception which also protects against Sexually Transmitted Infection (STI).
If you are at risk of having contracted a sexually transmitted infection, for instance you have had unprotected sex or a condom has split, you should seek advice from your family doctor or local family planning clinic. Sexually transmitted infections can have no symptoms and seriously affect your future fertility. If you have had unprotected sex with someone whom you believe to be HIV positive you should attend your local accident and emergency department as medicine can be provided which drastically reduces the chances of you contracting the infection. The sooner the medicine is given the higher the success rate and therefore you should seek help straight away.
