Barrier Methods of Birth Control
Condoms
Condoms are used each time you have sex. 18 for every 100 people using condoms will get pregnant in a year so they are typically 82% effective.
- Condoms act as a physical barrier to sperm
- They are not as effective as other methods but they are the only form of birth control that also prevent sexually transmitted infection
Diaphragm
What is a diaphragm? It is a soft silicone cup to use each time you have sex. Spermicide jelly is placed inside and the cup is placed in the vagina to hold the spermicide next to the cervix.
How does it work? The cup is a physical barrier to the sperm and the spermicide stops the sperm chemically.
How effective is it? Similar to condoms, about 2% of patients will become pregnant in one year of perfect use. Since they need to be used each time you have sex, about 25% of people who choose this as their method get pregnant (because they don’t use it every time).
How do I get a diaphragm? You will need to be fitted for a diaphragm and taught how to put it in your vagina correctly. We can do this at Willow Clinic.
What does it cost? Your BC Services Card pays for the fitting by the doctor and the diaphragm costs $50-$75.
Advantages: no hormones, no latex, controlled by the patient.
Disadvantages: must be used every time you have sex, not as effective as birth control pills or IUDs.
