Contraceptives Contraception, sometimes referred to as birth control, is used to prevent pregnancy. There are many options and it is important that when considering which one(s) to use, you review all potential risks and benefits with a health-care provider. A comprehensive guide to explore hormonal, non-hormonal, natural methods and emergency contraceptives was developed by The Society of Obstetricians and Gynecologists of Canada in partnership with sexandu.ca. Condoms are the only form of contraception that will reduce the likelihood of a sexually transmitted infection (STI) and unplanned pregnancy. There are two forms available, external condoms (sometimes referred to as male condoms) and internal condoms (sometimes referred to as female condoms). It is important to always use a new condom when you switch between oral, anal or vaginal sex. Lubricant is very important as using a water-based lubricant for vaginal or anal sex helps reduce the risk of the condom breaking. Learn how to use a condom.
