Condoms are barrier devices that reduce the risk of pregnancy and sexually transmitted diseases. There are male condoms that are placed on an erect penis and female condoms that can be inserted into a vagina. The benefits of condoms are that they can be purchased at many stores and do not interfere with a woman’s hormonal cycles. They are not as effective as other forms of birth control because they can break. Another problem is that people who use condoms for birth control don’t always use them consistently, every time they have intercourse.
