BARRIER METHODS
The male condom is the most popular barrier method. The condom is also available in a female version, which is made of polyurethane. The female condom has a flexible ring at each end – one secures behind the pubic bone to hold the condom in place, while the other ring stays outside the vagina. Condoms are available over-the-counter at all pharmacies. The condom is designed for one-time use and protects against sexually transmitted diseases (STDs) and HIV.
Effectiveness: Used correctly, the typical failure rate of male condoms is about 3%. However, application problems and breakage can occur with condoms. When used incorrectly, the failure rate for condom use rises to 12%. Used perfectly and consistently female condom has a failure rate of 5%. This means that out of 100 women using the female condom correctly for one year, 5 will become pregnant.
Side effects: Some people can develop allergies to latex condoms, however, non-latex condoms are available at pharmacies.
The cervical cap – device that is contained completely within the vagina. It is the smallest cervical barrier and stays in place by suction to the cervix or to the vaginal walls. The cap must be fitted by a health professional (not every time you use it) and used with a spermicide. The cervical cap prevents sperm from entering the uterus.
Effectiveness: In studies, 10-13 women out of 100 who use the cap for one year will become pregnant. The pregnancy rate rises for women who have already had children. The use of spermicide is absolutely necessary in order to derive the full contraceptive benefit of the cap.
Side effects: Sensitivity or allergy to the rubber or to the spermicide can occur. You should also have a regular Pap smear to check for any inflammation around the cervix.
