The condom is the only available barrier contraception used by men. It is cheap and easily available. It has very few side effects and protects both men and women against sexually transmitted diseases such as AIDS . The condom collects the sperm and prevents the sperm from entering the cervix and fertilising the egg.
Condoms are effective if properly used.
Here are some instructions for men on the use of condoms. A new condom must be used every time you have sexual intercourse. The condom must be put on the erect penis before entering the woman. As the penis is being withdrawn, the condom must be held to ensure that it does not slip off and allow sperm to enter the vagina.
