The contraceptive injection contains progestogen hormone which is similar to the hormone naturally produced.
It works by stopping the ovaries from releasing an egg each month (ovulation). It also thickens the mucus in the cervix preventing sperm reaching the egg and thins the lining of the uterus so it is less likely to accept a fertilised egg.
The injection is administered by a doctor or nurse and can be done at either your GP practice or local sexual health clinic
