Birth Control Myths

Birth Control Myths:

There are birth-control methods that are medically proven to be effective in preventing an unwanted pregnancy. There are also many other methods that some people think will work to avoid pregnancy, but don't. It's great that you're reading about birth-control methods. It's just as important for you to know what doesn't work as what does. If you don't want to get pregnant, don't believe or practice any of the following so-called birth-control methods.

Several myths, or stories, about birth control deal with what is supposed to be the "safe" time of the month for a woman. Maybe you've heard that a woman can have intercourse without worrying about pregnancy 3 days before and 3 days after her period. Or that she can't get pregnant during her period.

NONE OF THIS IS TRUE. Unless you are using a medically proven effective method of birth control, she could get pregnant any time of the month that she has sexual intercourse. There are several reasons for this. Even if a woman's periods are pretty regular, she can never be sure when her ovaries are releasing an egg. Ovulation, the release of the egg from the ovaries, has nothing to do with when you had your last period. It depends on when you will have your next period, which is something you can never be sure of. Especially for younger women, this is a very risky approach to birth control, because for the first few years, the woman's periods will probably be very irregular.


Sickness, emotional strain and even a change in the seasons can affect the ovulation cycle in women of all ages. Remember also that the life of sperm is 5 to 7 days. Trying to figure out the safe period of the month is also called the rhythm method; it is very unsafe.


Some people believe that you can rinse out sperm from the vagina and uterus after sexual intercourse. You may have heard that douching--which means squirting a liquid into the vagina--will rinse out the sperm, or that urinating or taking a bath or shower will wash it out. WRONG! Another myth.

Douching with Coca-Cola is supposed to kill sperm--and it does, but is not recommended.

Some people think that deodorant vaginal suppositories or deodorant vaginal sprays will also kill sperm. Again, none of these are methods of birth control. Equally important is the fact that they can be harmful, and none of them work.


There are stories that say you can't get pregnant depending on how you "do it," or how often you've done it before. One says you can't get pregnant if you do it standing up, another that you can't get pregnant if you're doing it for the first time.

I remember hearing that you couldn't get pregnant during the full moon if you "did it" standing up in a closet. Now that sounds a bit like a myth, doesn't it? It IS a myth. Warning: A birth-control method that depends on position or how many times you have sex is not a birth-control method.



Some people believe that a woman can't conceive if she doesn't have an orgasm. The fact is that whether or not a woman has an orgasm has nothing to do with her ability to get pregnant.



Some couples rely on having the guy pull out--that is, removing the man's penis form the woman's vagina just before he thinks he will ejaculate. This is just as risky as any other things we've talked about. First, there is usually a drop or two of clear fluid at the tip of the penis that appears before ejaculation, and these drops usually contain a few sperm. Since it takes only one sperm to unite with the egg for pregnancy to occur, ejaculation isn't always necessary. Sometimes all it takes is putting the penis inside the vagina. Second, ejaculation is often such a powerful physical and emotional feeling that a guy doesn't have total control over it, no matter what he thinks. Sometimes a man means to pull out but gets carried away and doesn't. Also, it's hard for a guy to know exactly when he'll ejaculate. Third, if a guy pulls out and ejaculates near his partner's vagina, a few sperm might mix with the moisture around the vagina and move into it. Some sperm are great swimmers!



Birth-control pills are very effective--but only if the pills are taken according to your the correct directions, as we discussed in the Pill section. Many people believe that being on the pill means taking one a month, or one before sexual intercourse, or one after. See the FAQ pages for what to do if you missed a pill. If you want something to use once a month, read about Lunelle or Depo-Provera.

Plastic sandwich wrap around the penis may sound like a good substitute for a condom, but it's not! Wrap your lunch with it instead.

No, toothpaste is not a spermicide. Never use it in place of one. (Yes, people have asked that.)


We can't tell you all the myths about birth control, because there are new ones being invented all the time. If you don't want to get pregnant or get someone pregnant, be suspicious of any method that hasn't been proven medically effective. To get information on methods that work to prevent an unwanted pregnancy, visit your health-care provider, a birth-control clinic or an organization such as Planned Parenthood.
