Rates of Contraceptive Failure When Unprotected Intercourse Has Occurred 6-14 Days Prior to Contraceptive Initiation

This project will quantify rates of contraceptive failure when unprotected intercourse occurs
5-14 days prior to initiation of highly effective reversible contraceptives (such as IUD's
and Implants).

Women seeking emergency contraception (EC) frequently report multiple recent episodes of
unprotected sex. Although high sensitivity urine pregnancy tests effectively rule-out
pregnancy resulting from sex that occurred more than 14 days ago, clinicians are frequently
concerned that pregnancy may result from unprotected sex that occurred <14 days prior to IUD
placement. Placement of a copper IUD within 5 days of unprotected sex is a highly effective
form of EC. Among 52 Chinese women who reported unprotected intercourse 5-7 days prior to
copper IUD insertion, no pregnancies occurred. However, the effectiveness of the copper IUD
when unprotected sex occurs 7-14 days prior to IUD placement is unknown. Intrauterine
pregnancies rarely occur with a copper IUD in place. As some clinicians are concerned about
injuring a pregnancy that occurs with an IUD in place, women who have had unprotected sex
7-14 days prior to requesting IUD placement are typically told they must use another, less
effective, contraceptive for 2+ weeks and then return to obtain an IUD. To remove this
barrier to emergency placement of a copper IUD, we propose to study rates of pregnancy when a
copper IUD is placed "any time a urine pregnancy test is negative." We believe that
simplifying guidance regarding the recommended timing of copper IUD placement has the
potential to significantly increase the number of women offered "same-day" IUD service.

Inclusion Criteria:

- Women between the ages of 15 and 45 years who request injectable, subdermal, or
intrauterine contraception, 6-14 days after having unprotected intercourse.

Exclusion Criteria:

- History of tubal ligation or hysterectomy.

- Positive urine pregnancy test
