There are several types of contraception, that is, protection against pregnancy:
1. Combined oral contraceptives (Diane-35, Jeanine, Anteovin, Trinovum). They contain in their composition as estrogens and progesterones. And, unfortunately, not suitable for everyone.
2. Progesterone contraceptives or miles-drank (Microlut, Charozetta, Bret). They suit those who are contraindicated to COC.
3. Injection that contains only progesterone (Depo-provera).
4. Parenteral implant containing progesterone (Norplant).
All of these types of contraception have their own positive and negative sides.
For example, combined oral contraceptives (COCs). They are easy to use, rid of the fear of unwanted pregnancy, do not prevent conception of a child's future and have virtually no side effects. But to apply them it is necessary every day.
For miles--drank characteristically less impact on the human body, no side effects of during lactation, convenient to use, relieve fear. But they are not as effective as the first and there is a high probability of uterine bleeding.
Intramuscular injections are used in the initial days of menstruation, and then once in 3 months. They are convenient because they do not need to apply every day, have high efficacy, duration of action of the drug is almost not prevent the conception of a child's future, save from the fear of pregnancy, no complications.
Subcutaneous implants done once a year. Under the skin put a capsule, which is constantly in the right quantities secretes progesterone. This is convenient since a year nothing need to worry, the high efficiency, reversibility, the ability to use the drug daily, no complications. But frequent spotting, and the capsule can only be removed surgically.
