All combined hormonal methods are comparable in terms of contraceptive efficacy; they all have the same optimal safety features, reversibility and ease of use. What changes is the method of intake, which can be more or less convenient depending on the needs and perception of each individual woman. The patch should be applied to the skin and replaced every week. The ring should be placed in the vagina, where it remains for three weeks. This latter requires more familiarity with your own body, and requires less manual work. The combined pill has the advantage of existing in many combinations and different dosage regimens so that you can find the one that best fits your needs, as if it were designed especially for you!
