1. The Classic Condom
A male condom is the most popular form of barrier birth control, and the easiest to find. The male condom is most often made from latex, which is waterproof. The condom is placed on the erect penis prior to intercourse. It blocks ejaculated semen from entering the other person's body. Condoms should always be used because they not only serve as birth control, but also protection from STDs.
2. The Other Condom
A female condom is another of the barrier birth control methods. It is as effective as birth control and provides protection from STDs because it physically blocks semen from entering the body. The female condom has a ring at each end of the condom. The ring on the closed end is inserted behind the pubic bone to keep it in place. The ring on the open end stays outside the vagina. Female condoms are more expensive and harder to find than male condoms. They are also less effective.
3. The Sponge
A sponge combines the barrier method of birth control with spermicidal method. It is inserted into the vagina prior to intercourse. It sits right over the cervix, which is the uppermost part of the vagina. A woman can insert the sponge right before intercourse or hours before. The sponges are also soaked in spermicidal, which will kill sperm as they enter the vagina.
4. The Cap
The cervical cap blocks sperm in the vagina from entering the uterus. A cap is not something that can be found in a drugstore, so it is more expensive and harder to find than other barrier methods. A woman needs to visit a gynecologist to determine if a cervical cap would work for her. If it is determined that it is a good birth control option, the woman is fitted for a certain size.
5. The Diaphragm
The diaphragm is a barrier form of birth control that is entered into the woman's vagina directly prior to sex. The diaphragm is most often made of silicone so it is very soft and cannot be felt during intercourse. A woman needs to be fitted for a diaphragm by a doctor. The diaphragm fits securely against the wall of the vagina and covers the cervix, preventing sperm from entering.
