What are the advantages and disadvantages of hormone-based contraceptive methods such as birth control pills, implants, and a patch.

Hormonal contraceptives are methods for preventing pregnancy based on synthetic forms of female hormones: estrogen and progesterone. Some of these methods combine the two hormones, while others only have progesterone. They can be taken, injected, inserted into the vagina, applied to the skin or implanted under the skin.
