RISK: The combined pill can cause headaches
BENEFIT: It is free

RISK: The Male condom is the least effective as it can split or leak
BENEFIT: Is inexpensive and often free

RISK: Requires an operation. (However, it cannot be reversed, so if they are planning to have a family in the future, they cannot)
BENEFIT: Is 100% effective
