Contraception in Wisconsin: a review.

The Contraceptive Equality Mandate took effect in Wisconsin on January 1, 2010. This mandate from the Wisconsin Office of the Commissioner of Insurance requires all insurance companies in the state of Wisconsin to cover all types of contraception, making Wisconsin the 28th state to do so. This article reviews the literature related to several types of contraception including Implanon (a newly available implantable contraception), drospirenone-containing oral contraceptive pills, and intrauterine devices. We also review evidence regarding depot medroxyprogesterone acetate and bone mineral density, and new cycling regimens for oral contraceptive pills.
