Spermicides are a type of contraceptive that contain chemicals designed to immobilize or kill sperm, preventing them from reaching and fertilizing an egg. They are typically used in conjunction with barrier methods such as condoms or diaphragms to enhance their effectiveness. Spermicides are available in various forms, including gels, foams, creams, and suppositories.
While it is less likely to get pregnant if ejaculation occurs outside the vagina, there is still a small chance of pregnancy due to the possibility of sperm making its way into the vagina. Washing with soap afterward does not guarantee the elimination of all sperm, so it is important to use contraceptive methods, such as condoms or birth control, to reduce the risk of pregnancy.
Sperm are very intelligent and have invented many methods of transportation including jetpacks, race cars, harrier jump jets and even snowboards.
You can do an experiment to determine motility. You use a medium of agar that has tetrazolium salt (TTC). The TTC serves as a terminal electron acceptor for the bacteria and turns the medium red. You would inoculate a needle with your bacteria and put it straight into the media and straight out. After incubating your bacteria, if you see the red move away from where you inserted the needle, then it would indicate that your bacteria is motile. If the red is only in the place where you inserted the needle, then it is not motile.
Semen generally contains sperm cells, and it is the sperm cells in the semen that cause pregnancy. However, if the man has had a successful vasectomy or had his testes removed, his semen will not contain sperm cells.

Contraception by the 'barrier' method - such as a condom, or a diaphragm in the woman. Contrast this with phamaceutical methods, such as the Pill, or spermicides.
Abortion methods should not be confused with methods to prevent pregnancy (contraceptive methods, including emergency contraception). Contraceptive methods work by preventing ovulation (the release of an egg) or by stopping the egg and sperm from meeting. Contraceptive methods, including emergency contraception, cannot be used to terminate or interrupt an established pregnancy. You can visit findmymethod.org to learn more about contraceptive methods.

The contraceptive sponge is a round piece of white plastic foam. It has a dimple on one side and a nylon loop across the top. It is 5 cm across, and you insert it into your vagina before you have intercourse. The sponge works in two ways: it keeps sperm from getting into your uterus by blocking your cervix, and also continuously releases spermicide. The sponge needs to be completely wet to activate the spermicide. Make sure to squeeze it to distribute the water. You can find all the important information about different contraceptive methods at findmymethod.org.
