Contraceptive Injection
The contraceptive injection contains the hormone progestogen which prevents pregnancy by stopping the ovaries releasing an egg (ovulation).
How effective is the contraceptive injection?
If used correctly (no missed injections) the contraceptive injection is over 99% effective (this means that each year less than one woman in a 100 will get pregnant using this method to prevent pregnancy).
