Various methods of birth control are available.

Abstinence: Celibacy or sexual abstinence means avoiding sexual intercourse.

Withdrawal: Also known as coitus interruptus, this is when the man removes the penis from the vagina so that ejaculation occurs outside of the vagina. In theory, this prevents the sperm from being deposited in the vagina.

According to the United States Health and Human Services (HHS) Office for Population Affairs, each year, for every 100 women who use this method, 20 may become pregnant.

In other words, withdrawal is about 80 percent effective, but this depends on how carefully and how consistently it is used.

The penis does not need to enter the vagina for pregnancy to occur. It can happen if sperm enters the vagina during foreplay, for example.


Barrier devices prevent the sperm from meeting the egg. They may be combined with spermicide, which kills the sperm.

Male condom

The male condom forms a barrier and prevents pregnancy by stopping sperm from entering the vagina. It is placed over the penis before sexual intercourse begins. A condom is made of polyurethane or latex.

It can also help to prevent the spread of sexually transmitted infections (STIs).

It is around 82 percent effective. Some 18 women in every 100 may conceive if their partner uses a condom.

Condoms are available from drugstores, supermarkets, and many other outlets. Health providers also supply them, sometimes for free. You can also purchase them online.

Female condom

The female condom, or femidom, is made of polyurethane. It has a flexible ring at each end. One fixes behind the pubic bone to hold the condom in place, while the other ring stays outside the vagina.

Spermicides may be placed in the vagina before intercourse. A spermicide kills sperm chemically. The product may be used alone or in combination with a physical barrier.

The female condom is 79 percent effective. Around 21 women will become pregnant each year with this method.

The femidom is less easy to find than the male condom. Only the FDA-approved FC2 is available in the United States. Health providers may supply them, or you can get them from a drugstore on prescription. You can also buy them online from Amazon or from the FC2 website.

A cervical cap is a thimble-shaped, latex rubber barrier device that fits over the cervix and blocks sperm from entering the uterus. The cap should be about one-third filled with spermicide before inserting. It stays in place by suction.

It is around 88 percent effective if used with spermicide, and 77 to 83 percent effective without.
