Spermicide

Using a spermicide is a form of contraception that is best used in combination of diaphragm, female condom or sponges. It can be safely used during breast feeding. A spermicide can be used in the form of a cream, foam or suppository. It prevents sperms from moving, thereby preventing fertilization. Some spermicides act as a barrier to entry of sperm into the cervix. A spermicide must be used about 10 minutes before you have intercourse. It is effective for about an hour after insertion. Some brands of spermicides cause irritation. Many women complain of spermicides being messy. Nonoxynol-9 is a commonly used spermicide. Read instructions on inserting spermicides carefully. Failure to use it correctly reduces its effectiveness.
