Contraceptive patch

What is it? The contraceptive patch looks like a small plaster that is applied to the skin. It works by releasing two hormones oestrogen and progestogen through the skin. These hormones prevent ovulation (release of an egg from the ovary) and thicken the cervical mucus, creating a barrier to prevent sperm from entering the uterus.
