Current controversies with oral emergency contraception.

Emergency contraception (EC) is a method to be used in the case of unprotected sexual intercourse, failure of a regular contraceptive method, or after rape to try to prevent an unintended pregnancy. Oral EC remains surrounded by controversy, much due to myths and misconceptions among the public, policy makers and healthcare providers. This has resulted in restrictions on its availability in many parts of the world and restrictions on women's access to it. The aim of this article is to provide an evidence-based view on some of these common controversial issues surrounding oral EC in clinical practice. TWEETABLE ABSTRACT: Controversy about emergency contraception restricts access for women.

Emergency contraception and impact on abortion rates.

Emergency contraception (EC) is a drug or a device that is taken after sexual intercourse to prevent unintended pregnancy. The most effective EC is the copper-bearing intrauterine device (Cu-IUD), but oral EC methods are more commonly used and include a single dose of either levonorgestrel (1.5 mg) or ulipristal acetate (30 mg). Although all EC methods are extremely safe, access to EC is often limited due to prevailing misconceptions over how EC works. Although EC can prevent unintended pregnancy for an individual woman, it has failed to make an impact on abortion rates at a population level. This may be because it is not used after every episode of unprotected sex and because existing oral EC methods are only effective if used before ovulation. Future strategies around EC should focus on maximising uptake of Cu-IUD, facilitating initiation of effective regular contraception after EC and developing a more effective oral EC.
